Better Buys including Ali-buys

Here are the products purchased from AliExpress, ebay or other online commerce platforms that were useful or better than or equal to my expectations or those that were not as such but could be bettered with some customizations, not all of those but some of my major concerns.
Products with great cost-effectiveness would also be reviewed in detail.

< From March, 2023 till the date of this writing >

Mainly describes how-tos regarding customizing those products that seem to be less attractive to keep onwards or could be bettered by some customizations after purchase.

5PCS Kailh Mouse Micro Switch 80M 3 Pin GM8.0
Delivered fast. All units look and feel good.

The mouse button switch works fine after replacement.
My almost dying mouse had been revived and it is still alive and kicking as of the day of this writing!

Order: Mar 23, 2023 Delivered: Apr 06, 2023

10PCS Kailh Mouse Mute Button, 6*6*7.3mm
It has arrived much earlier than scheduled without any shipping fee. All the units look and feel good and are working fine.

My HP mouse and others whose switches had been replaced with these are still working fine without errors, as of Sep 21, 2024. I have been writing this article with the very HP mouse fixed.

G50 Wireless Bluetooth Speaker with FM Radio
Cost-effective, bettered with customization.
Superb! It looks good, finished good and works all right. Bluetooth speaker, FM Radio, clock... all working fine. The quality of sound isn't bad for its price. It keeps the time even when it has been turned off then turned on again.
But it has a demerit: Its sound volume has to be re-adjusted whenever the FM Radio is turned on. It seems to be starting with its maximum volume. Otherwise a super product. Quick delivery in few days (and even 1 day earlier than scheduled). Low price( cannot say they are cheap but just really inexpensive ).

I later replaced its 18650 battery with another having greater total capacity. From about 900mAh to 1500mAh to get longer run-time duration from a single full charge.

Simple Style Folding Computer Desk
Cost-effective, bettered with customization after purchase.
It has arrived in few days as always. Great bargain! It is really good for its price. Well-polished with a strong and sleek board and edge-rounded metal legs. Its leg joints does not seem to be very robust, though.
A very small trivial defect was found on its board, which could be simply ignored for its price. BTW, a great product for its price! Dimension:60cm x 40cm.

gukeedianzi Replaceable battery 2600mAh for COWON D2 series
A well-made product with small but helpful aiding tools. It has greater capacity than the original Cowon D2 battery which has 1800mA. But this one boasts of way greater capacity of 2600mA.
The default Cowon battery lasts longer than that of most other devices with similar features, but this one has even greater capacity and costs less than D2's original battery. My Cowon D2 has revived and started working fine again. I hope this battery has greater durability also.

I'm still using the PMP device that is, Cowon D2 with the battery. The capacity of the battery actually turned out to be over about 2800mAh. The charge was performed with USB power source for the test while it could be charged way faster with its own charger. Nice seller and a durable quality battery.

TR6 Bluetooth USB Receiving Transmitter 2-in-1 Audio Adapter
Not recommended as there are better products in the same price ranges but just a usable product.
Listed it here for reference's sake for novice users of this kind of product and for comparison with other better products.
Both of the RX and TX mode work fine. There was some noise while using it. It has converted my non-BT TV to a Bluetooth-speaker output capable one. It has made all my wired speakers and earphones Bluetooth-capable.

There's some noise with earphones while it does not transmit any sound and little delay on transmitting sounds to a Bluetooth device (TX mode).

X2 Wired in-Ear Eearset
Quality product with cost-effectiveness.
Its sound quality is good and its cables and covers are all rigid and finished right. Good to wear different way from other earphones.
Wearing from back to the front ear-round. And it emits no closed or dull sound unlike other low-priced ones. It has clear sound but its bass seems to be a bit weak. I hope its durability will be good too.

Simply great for its price. Enough bass portion and clearly heard high-pitch tones. Both are well-mixed. But it seems it lacks a bit in middle range tone of sound. And its gears do not fall off from ears easily. A good buy.

Order: Apr 19, 2023 Delivered: Apr 25, 2023

Essager Bluetooth 5.0 Receiver
Quality product with cost-effectiveness.
Works fine for converting a wired speaker or ear-set to a Bluetooth capable one.
Well-made and clean-cut thus looks sleek. Its male-to-male gender makes it more versatile.

It transfers clean and clear, balanced sound and it involves no noise even with earphones. Of course speakers connected with it do not evolve any noise even while no sound is being transferred. Having been working fine until now without and disorder. Surprising quality for its price.

S20 Mirror Bluetooth Earset 5.1 Black
Quality product with cost-effectiveness.
Very nice! Its sound quality is almost the same as those with 10 times more expensive price than this, I presume based on my use. Looks and feels robust overall. What concerns me further now is its durability. I hope it will be also good.

Its clear and well-balanced high-, middle-, row-pitch range sound tones make me feel inclined to listen to it anytime. Still working fine without any disorder or malfunction. Quite a quality product!

Essager 2M 540 Rotate 3A Fast Charging Magnetic USB Type C Cable
Well-made, cost-effective.
Ordered: May 5th, arrived: May 11th. Its magnetic strength exceled my presumption. Strong enough not to be disconnected with any small accidental touch. And its rope is robust and cleanly finished. Supports fast charging and fast data transfer.

Its actual maximum charging capacity is 15W with Xiaomi Redmi Note 12 whose maximum capable capacity is declared to be 33W. But most capable cables support up to 25W actually for it. But this cable supports lower wattage volume than that as : 5V → 10W - OK. 9V → 15W 10W.
BTW: Eessager's magnetic cables do not work for charging a device with the current of below one watt. It has been verified by myself while trying to charge a hybrid solar-charged lamp which also supports electrical charge at a very low wattage (below one).
All other non-magnetic cables seem to work fine for charging with the very low wattage regardless of the brand of the cable. The point is that Essager's magnetic cables cannot charge a device supporting charge only with a very low wattage. Thus I could not charge the hybrid solar lamp with any of Essager's magnetic cable.
But their cable's quality is great overall. I have never been disappointed with their cables in quality.
Order: May 05, 2023 Delivered: May 11, 2023

2 packs of Essager Type-C USB cable
Well-made, cost-effective.
It is just a single meter long which may be proper for most transferring or charging tasks without losing much of data or current being transmitted through it. Even better, it supports high-speed charging also.

Its maximum available wattage for a mobile phone of Xiaomi which is declared to support 33W fast charging was 15W maximum. But actually the phone only supports 27W maximum, but mostly 25W in use. As most other C-to-A types of cables also support the 15W as maximum its performance/capacity could be labeled as normal.
But its quality is relatively and competitively better than most other cables around.

Rectangular Solar Outdoor LED Wall Lamp
Cost-effective. Customized for betterness after purchase.
Ordered: May 6th, arrived: May 11th. Works right out of the box.

Personally I evaluate it as one of the superior solar lamps sold on AliExpress.
Brightness, battery duration, reliability, charging capability and capacity, all good. A good cost-effective buy.

Order: May 06, 2023 Delivered: May 11, 2023
2nd:
10-18/10-25. 7 days delivery. Arrived in a box without any manual inside it but with all of its parts and a remote controller. The remote controller uses CR122 lithium cell battery which is already installed inside it. It works within a distance of three meters.
But at times it does not work arbitrarily even within the working range. Also, it isn't quite easy to pin-pointedly press a desired button on the remote controller. Its composing plastic material has some improvements(sturdier and well-polished). All other parts are also finished better than before.
All its lighting settings could be set or changed with its accompanying remote controller. But it does not remember previously used settings. Most of all, now it has a physical switch to turn it on/off which ensures to keep it from working in unwanted ways or occasions.
However it still leaves much room for improvement with some customizations, though.
I personally regard it as one of the nicer cost-effective solar lamps sold on AliExpress.

Fingerless LED Gloves
It uses a 3V CR2016 button battery for each glove. And these two batteries were already installed in these gloves on arrival. No other extra lights are needed when working with parts in a PC even in a dark room.
And handy as no additional movements of lights needed whenever the user's hands move. This is really a handy gadget provided at such a low price: Two pairs with batteries for each.

100 LED Solar wall lamp Pentagon
Cost-effective. Customized for betterness after purchase.
Works right out of the box. Its light was brighter than expected and it had some steps of brightness adjustment devices implemented.

Its solar charging works fine under strong sunlight. But it does not seem to be charging properly under dim or gloomy weather.
Anyway, it works fine under right conditions. Its sensor also works fine as described.

Order: May 06, 2023 Delivered: May 11, 2023
2nd Buy:
2nd buy of the same item. Its battery seems to last shorter than expected as time goes by but it is being solar-charged right anyhow.

Mini Intelligent Sweeping Robot
Simple and a bit clumsy but cost-effective.
It works anyhow after getting all parts assembled for an entity product. It seems its power is little weak. but its sensor works right most of the time but it gets stuck in a spot and does not come out from there at times.

It could not gather things that are heavier or equal to a piece of rice in weight and turns only in one direction (anti-clockwise) when met with an obstacle which it cannot pass through. Its power is too weak to clean up all tiny debris. It sometimes cannot gather long hair drops.
Anyway it works in its own tiny capacity and with its tiny limited power. Proper price for its capability. Limited tiny dirt master in short.

Dual channel mini Bluetooth power amp
DIY, cost-effective.
A buyer should assemble it after purchase, which is easy even without any manual. It works fine both in Bluetooth mode and with wired connection via 3.5 mm AUX jack. Yes, it supports Bluetooth.
Good product for its price. But there were some stains and dirt on its board even though it had been delivered sealed.
FYI, this version does not include any USB port or SD card slot.

HIFI Bass Wireless Bluetooth 5.0 Headset
Bettered by customization after purchase.
Arrived in 3 days. What a delivery! Its ear caps are wide and long so these may not cause ear-aches with long wears and tears. High parts are being clearly heard and low parts are heavy enough but it emits sort of inner-can sound. which is one of the most easily encountered symptoms with low-priced products. This defect tends to deteriorate overall sound quality no matter how clear the sound is.
Yet it can be also used as a wired headphone without power on. It could be a merit. And it has some other handy features such as TF card playing and some. Good product for its price with one-and-only big demerit after all.

Additional summary after use since its buy:
- Capable of playing what are in a 128GB SD card.
- True stereo system.
- Charge by USB type-C port.
- Bluetooth v5.1 : Better locating, better and prompter connectivity.
- It started to announce several charge prompts after 2 hours and 37 minutes of contiguous use.
- After about five or so times of the prompt announcements, it automatically powered itself off in two or more minutes.
- FM radio and TF Card playing feature exist.
- It has been working fine with 128 GB sized micro SDXC card in TF Card mode but not sure about bigger ones...
- Total running time turned out to be about 3 hours in TF Card mode and about 8 hours and 30 minutes in Bluetooth mode.
- Short Battery Longevity : Its battery has been verified to be of only 150 ~ 180mAh maximum which plays sounds in TF card mode for about only three hours maximum.
Not adequate for serious music listening.
However, it could be mentioned as a cost-effective, versatile and useable headset after all.

Deli-3.6V Electric Screw Driver
Took 3 days only for delivery. It exerts much stronger power than I have thought it would. Left, right directions support. It accompanies various cross-headed and other driver bits with a micron 5-pin charger cable, not a C-type one.
But it does not support speed variations. No such options wheresoever. Guessing from its power it might penetrate a metal side panel of a computer case.
Clean-cut and well finished product deviating a bit from what has been advertised on its web site. BTW, a good buy overall for its price.

Its power is great. I could not stop the turning drill bit with two of my fingers on its upside and downside no matter how much power I put on to my both fingers. But what can be of concern to buyers might be the speed not the torque it exerts on drilling or tightening a screw.
And I tried to penetrate a mental cover of a PC case which is rather thicker than those of most low-priced ones. The result was a success with a hard trying for about 5 to 10 minutes of drilling on the surface. The outcomes are shown on the images attached. It is a good drill for its price. BTW, I used it out of the box without electronically charging it at all.

Essager 65W GaN USB Type-C chargers
Black:
It has charged a cellular phone of mime once from start to end. And that's when its life has ended silently. It never worked after that. It worked perfectly as a single-use-only product.
It has one USB type A port and two type C ports. None of them worked then. And its accompanying C2C cable had some stains on its connector node, so I had to wipe it out before use.

Full replacement:
I asked them for a new product with a video describing the product disorders which was not working at all. And they sent me a new one as I asked, after a while, which has arrived on July 19. (just about 20 days for delivery after I had received their message about the new one to be sent)
A whole new product of the same kind has arrived much earlier than scheduled which was September 5, without any shipping fee. And this instance works fine with all its 3 ports. I felt they really care for user's experiences for betterments. A promising brand, I presume!

White:
Clean-cut, sleek, well-composed, flexible, modern design.
Somewhat bigger and heavier than most other chargers around, proportionate to its versatile features and flexibility . It works fine and has a detachable socket head for different sockets and voltages. That's very handy and flexible feature.
Provides two USB ports. One USB A and the other Type C ports while it has room for another port. Users need not buy another separate chargers per country because changing its header to an appropriate one would do with it, as the header alone is being sold separately. But it was way expensive than I have expected.

Deli 13-Inches Tool Bag
Delivered in a single day. Fabulous swiftness for overseas delivery!
Well-organized, well-finished with handy pockets inside outside. Robust, and tough fabric consists its cover and bottom area. Its bottom is thick enough to hold heavy stuff hard. Its size is a bit smaller than what it looks like in the advertising images.
Steel rods inside its cover cloths extend and uphold the cover cloths upright and tight. Provides a long shoulder-around belt for carrying it around on one's shoulder. A quality robust neat tool bag in short.

Essager 7A USB Type-C Cable, 66W
Charge works fine at normal speed with a smart phone having 5v,2A charging capability. Data transfer speed equals to that of USB 2.0 specification. A good buy of two packs at a low price.

While several other Essager C-to-C 100W cables exert up to 25W, it exerts 15W maximum, for charging a smart phone actually supporting 27W (9v, 3A). That might be related to USB A port limitations, I guess.
BTW, it had been well-finished and sturdy enough to last to date without any flaws or errors.

Aluminum Alloy Phone Holder, Singpod
A quality product. Made of metal not just metal but rather of heavy kind. It is the heaviest of all such holders I've ever purchased thus very stable and sits firm on the ground. Unlike similar non-metal products, it does not rock when a spot is touched with a finger. Stern and firm.
I could also feel its robustness by its weight. And it rotates 360 degrees horizontally by little steps, not to mention vertical front and rear tilting. One demerit is that its height cannot be adjusted flexibly as it bears few joints, which can be gracefully ignored for other great merits. It may well hold light-weight tablets. A hyper-quality product, in short.

Order: May 25, 2023 Delivered: Jun 01, 2023
2nd buy:
2nd buy of the same product from the same seller with a different color this time, silver.
Previously I had bought the same kind with a black color. Sturdy, heavy and ultra-durable. Almost a crackerjack among phone holder products, I presume. A caveat is that its anti-slip rubber pads on both of its small legs deviate from its original position with many uses in a long period.
The thickness of its phone-touching plate has increased by 0.4mm from l.3 to 1.7mm. I have many other such phone holder gadgets but I have been mostly using it whenever such holder was needed.
On its durability: The state of the previous one is almost as same as it was first delivered here. No looseness of any joints. No fall-offs of any parts. Still firm on the ground. Just the sliding anti-slip pad is a tiny flaw that could be easily ignored. 'Singpod', I could not help remembering it. Almost a crackerjack with ultra-durability, in short.

Temperature-adjustable Electric Soldering Iron, 60W
Provided in a plastic vinyl only. It is somewhat smaller than common soldering sticks. But it provides several selective temperatures with visual red LED working notification inside its housing and quite quick to be heated up in full.

With a few months of use its connecting plastic joints have become loose and its working status has gone awry to the point that the soldering tip was about to fall off with further lots of uses. So I had to apply a strip of rubber tape a round around the male joint screw portion tightly with some strength and now it works fine again.
if its plastic material's quality were better(harder or denser) it would be a great cost-effective product as its functionalities are still all OK. Its heating up speed is still real quick and its temperatures are still high enough to melt down threads of soldering wire quick.

High Power LED Flashlights Rechargeable Camping Lantern
The two scopes of brightness levels are not much different from each other but only bright enough to be used outdoors.
- Front center light (2 scopes of brightness and a blinking mode)
- Front two side lights (2 scopes of brightness)
- Side light (single brightness)
Solar and electrical hybrid charging support: As it is geared mainly for solar charging, which is good, it is very slow on electrical charging.
Once a lighting source of the above three is selected, it is turned off right away not circulating all its lighting sources when its power button is pressed again after some meaningful seconds.
Handy as it is portable. The solar charging capacity and the working time of the charged battery are the main concern onwards.

It isn't easy to verify the exact capacity of its batteries as weather conditions are varying day by day. It could be somewhere between 800mAh~3800mAh judging from my current tests up until now.
BTW, The lamp could go awry easily if dropped from a height above 1 meter. If that's the case it might well not be a serious disorder mostly. Just any of the lines connected to a battery inside it might well have been disconnected thus it should be located and reconnected and then it would work right again.
A caveat is that there are several dim yellowish strips around the light's outmost diameter.
Some other few solar lamps also show this symptom.
Anyway it is a useable product.

18650 Power Bank case 20000mAh
White:
(3500mAh x 6 = about 20000mAh)
Its total capacity depends on that of each battery put inside it. Their declared 20000mAh is for batteries of 3500mAh capacity respectively, which is almost maximum available with normal 18650 batteries: (3500mAh x 6 = 21000mAh)
With 1500mAh batteries the total capacity mounts to only 9000mAh (1500 x 6) maximum and the total usable capacity is way less than that depending on its circuit's efficiency. Mostly less than 15 to 30%.

For real-time reference:

For the case of nominal total capacity of 21000mAh (3500 x6), the actual capacities are roughly expected to be as follows:
→real-time charging capacity: about 16000 ~ 19000mAh
→ Usable discharging capacity: about 13000 ~ 15000mAh.

For the real case of 9000mAh (1500 x6) of mine, the actual capacities verified were as follows:
→real-time charging capacity: about 8400mAh
→ Usable discharging capacity: about 5800mAh.
→ On my interim tests, the resulting battery efficiency was about 70 % as shown in the following image:

It has arrived here with covers firmly closed(which shouldn't had been) and I could not open it without breaking it. It does not support reopening it once closed, originally. So I couldn't even see its inside, initially.

I finally succeeded in managing to re-open the closed case and making it work right in hours of efforts. But it wasn't easy at all.
- Single-pressing its power button which is on the right side, turns it on for use.
- Then consecutively quick-pressing it twice turns it off.
- Long-pressing the button toggles turning on/off its small center light on its upper side.

Black:
2nd buy of the same product from the same seller with a different color this time, black.
Arrived here safely in a bubbled vinyl bag inside a box.
Previously I had bought the same kind with white color. This one has arrived with most of the housing parts as they were, not closed or assembled, which is the right state when it has reached a customer. It declares 5V, 2A charging maximum and it has kept the state as was. Thus I bought one more of it.
As its batteries are connected in parallel with each other it even works with only a single battery inside it, not to mention with only two also. It is currently being used with solar panels with 6 batteries in full. Its LCD display color seems to have become more natural than before. A nice cost-effective product.

The one in my images is with a black front and a white back covers. Its button on its right side needs to be modified a bit to function properly, otherwise it is stuck and wouldn't move at all. As of February 13, 2024.
Before closing the covers:
Some portion of the button should be cut off in order not to let the button be stuck between the outer cover and the actual tiny button inside it, as follows in my images, before closing it up with its covers.

Clip LED Desk Lamp
A product very disappointing but working fine only for a simple lighting and none other features.
Bettered by customization(DIY) which involved additional little cost.
To my dismay, does it lack the following of what has been asserted on its descriptions:
1. No USB charging: Wired USB charge only.
2. No touch switch (Just a classic analog on/off switch) - That's the only controller available for it.
3. No anti-slip pads on its bottom or around.
4. No dimming or selectable colors. The only controller available for it is the on/off button.
5. No brightness adjustment - just a single brightness. It is rather bright though. It could be sort of a console factor among all other disasters.
1st revision: not recommended as the two ports on the board are being made unusable.
I finally revised it to be a USB-chargeable portable lamp with additional little cost as follows:
[Total additional cost for the revision: US$1.25]
1. Voltage controller (motor speed controller) for brightness adjustment: US$0.15.
2. Lithium Polymer battery protection PCB board (The two ports on the board are not being used right now. Those are currently reserved for later re-revision): US$1.1.
3. [No cost for the 18650 battery as it is reuse of an existing one]
BTW, one thing that should be noted is that this lamp is not a recommended item as it differs much from what have been described on its description page. But it could be a right object for enhancements by DIY.

2nd revision: bettered.
I revised it again for better resource utilization using a TP4056 charger module replacing the previously-implemented over-spaec module. The way and the port for charging have changed also:

3rd revision: recommended.
I revised it once more for better functionalities adding a dimmer module and an on-off switch:

Essager 540 Rotational Magnetic Cable 3A
Robust and well-finished product. Works fine with 1A, 2A, 3A current capacities. Its magnetic connector tip enables quick switching between devices being charged or connected for data sharing.
Handy on switching between micro 5-pin and C-type phones on the spot, for example. I ordered rather moderately shorter one(1m) for little faster data transfer or electrical charging. (Cable length also talks for charging speed actually) A good buy at a low price.

Adequate for common moderate charge operations.

Essager USB Type A To USB C Cable 7A
Best cable of type A to C ever used, in look & feel, performance and features.
Works fine and got hardly no defects but the LCD screen for current display is a bit clumsy compared with what's been shown on its description page. Otherwise a nicer product.

It supports 15W charge under maximum 25 charge-capable environment of mine. As it is connected to a charger through USB A port (not type C) its does not seem to support the maximum available 25W charge. But it is one of the most capable, reliable and sturdy one of A-to-C type cables by my experiences.

However, as it is limited to my charging environment, the result might well be better under better charging environments.

Order: Jun 30, 2023 Delivered: Jul 15, 2023

Essager USB Type C To USB C Cable 100W
Best cable ever used.
Works fine with 1A/2A/3A (5W/10W/15W/27W) charging and...

It is one of the best cables I've been currently using for various purposes. It even has a little Liquid Crystal Display pane showing current amount of wattages being transferred through it.
It supports the maximum available wattage currently available under my charging environment which is only 25~27W. Xiaomi's Redmi Note 12 declared that it supports 33W but actually 25W was the maximum available for the phone.
And the charger should be 65W-capable to get the maximum wattage.

Its the same as Xiaomi's Turbo-charging performance.

Yes, it exerts the same performance through well-known PD protocol as Xiaomi's Turbo-charge capability without the turbo-charge protocol. No need to resort to the protocol, which is closed kind not open to public, for maximum charging performance with the Xiaomi phone. Great! Its durability is also good. No defects, disorders or malfunctions up until now.
Well-made, high-speed and sturdy product from Essager. But its fabricized cable is more rigid than those of most other similar cables'.

2nd buy:
Another buy of the same product at the same price from the same seller. I bought it again because it is too good to be bypassed. Now it could grip objects more firmly as the two would work as a pair.
It is truly sturdy, rigid and big enough to hold most objects.
Excellent cost-effectiveness and its quality is also superb!

LED Outdoor Solar Garden Street Lamp
Arrived in a boxed fashion. A remote controller with a battery(CR1220) already contained inside it accompanies it. Works right out of the box and bright enough to be used outdoors.
Like most other solar lamps of similar kinds it also supports three lighting modes. One caveat is that it squeaks loud when changing the sustaining stem tilt and requires quite a strength for doing it. But as it wouldn't change frequently it won't be quite a trouble actually.
Anyway, no severe defects found except for its battery damage by over-charge. No protection device implemented for that by default.

Thus I customized it for betterness later on as its battery had been damaged(swollen) by over-charge under the sun one day. It started to flicker though faintly and irritatingly while working and denied charging its battery under the sun.
So I fixed it repalcing the damaged battery with new one implementing a protective PCB board strip on it and it works fine now. Real nice, strong and durable after the fix.
Be ware that it needs a protective measure against over-charging as of August 12, 2023, or it may well be made unusable (dim lighting only and no charge available at all anymore no mater what) in a few days as soon as it has gotten over-charged under strong sunlight.

Portable Aluminum Laptop Stand
It might well be the real one for every one who had been searching for such metallic stand or holder. Previously, I had bought the same kind as this from somewhere else but made of plastic material overall. But now I've reached one that has been actually constructed with metallic material from ground up.
It even really sustains Acer Aspire v3-571G right which is very heavy for a notebook computer. (It should be duly labeled rather as a sketch book computer than notebook one) But it withstands the heavy sketch book computer which could not lean against the afore-mentioned one made of plastic even with very little slant.
Better not buy one made of plastic as that would collapse easily under most of the notebook computers around. This one is highly recommended instead of such ones. Obtained a long-sought-for right one here.

One of the best of the same kinds. Still working fine. Sturdy enough to last any longer.

Separated Solar COB Lamp
1st:
Works right out of the box and it is the brightest of all the other 4 kinds of solar lamps I've bought from AliExpress and it also seems to be lasting longest than the others. Sensors work fine in 3 different modes. Its separated solar-charging panel makes it more convenient and flexible.

Order: Aug 06, 2023 Delivered: Aug 18, 2023
2nd:
Purchased at a very low price compared to its features and components. It is so bright as to be used outdoors. Solar charge operation works adequate enough with its separate solar-charging panel so that it may last long as expected. A great bargain for its components and features.

4th:
It has become closer in light tone to that of the sun light: Warm white and this one involves no flickers. Its merit lies in the separation of the lamp from the solar-charging panel. Thus it is really useful in many ways. I also use its charging panel separately to charge a supplementary power bank, though it takes quite long... Cost-effective real energy-saving versatile item.

Kingbank KP230 Gen3x4 M.2 2280 NVME SSD 512GB
Great cost-effectiveness. Purchased it at about 16 dollars only. What a bargain!
The NVME M2 module and two screws for fixing it to a main board were there in the box. Its product details page does not mention the screws but these accompanied it anyhow. A heat sink panel is not included, of course.
The product is and works as they have described on its details page. I checked its capacity and it has been proved to be of adequate 476 Giga-bytes. It exerted the right speeds for its described specifications as I have performed these with CrystalDiskmark application as follows:
- Sequential read tasks : 3.5 GB/sec
- Sequential writes : 2.6 GB/sec
- Random read operations : 906 MB/sec
- Random sequential writes : 1.36 GB/sec
A greatly bargained product at a very low price compared with its equivalents.
Its durability is also fine as its price against quality.

I have been using it as main disk on which Windows OS had been installed and running fine ever since its buy. And it has been working fine to date (as of September 21, 2024) without any delay, misbehaves or malfunctions. Rather, my system has become a bit faster after its install.

6.5A USB Tester Digital Voltmeter Ammeter
Delivered in an air-bubble bag at a scheduled date. Good to support type-C port not to mention type-A. I was able to detect the exact battery capacity of my suspicious cellular phone from Xiaomi with it. Surprisingly, only a half(2500mAh) of their declared 5000mAh had been implemented inside the phone.
It would really be of help detecting such scam products onwards. A really nice gadget which could work as a real-life detective in this electronic world.
- Maximum detectable voltage: 32V.
- Maximum detectable current: 6.5A.
- Maximum detectable wattage: about 160 Wh.
- Maximum cumulative wattage: about 900Wh.
- Maximum cumulative current: about 90000 mAh.
It starts with a detailed information display and changes to simple three major values(Voltage, Amperage, Wattage) display status after scores of seconds by default. I've got a detective against a fake products.

Out of order, full replacement:
It has gone out of order in two months. The display didn't come back after being turned off on a day. So I contacted the seller and s/he suggested shipment of the same new product with no strings attached after looking into my video clips on the non-working product.
Took only 10 days for the delivery. Received the same whole set as the gone-awry product without any actual cost. Very good to see it working.

M.2 NVME to PCIe4.0 GEN4 X1 X4 Adapter
Well-made and working fine. Lacks none for its installment and operations. It is mainly geared for PCIE version 4.0 but it installs and works flawlessly on a system with PCIE version 3.0. Great bargain at such a low price. Its bracket is made of plastic but its mechanism of connection with the PCB board is of clever design. Fun and easy working with it.

Drivers and screws are all provided enough. Well-made and working fine. It is for PCIE version 4.0 but works fine also on a system with PCIE version 3.0.

It (PCIe x1) makes an NVME M2 module exert about 400MB/s on a system with PCIe version 2.0 and about 800MB/s on a system with PCIe version 3.0 regarding read/write speeds.

Type-c Mini 18650 TP4056 Lithium Battery Charger Module 5V 1A(10pcs)
Arrived way faster than usual via combined delivery with several other products. Exactly 10 pieces all told as ordered and I have tested all of them and all worked fine without exceptions.

I have fixed my charging-capability-disabled headset with it along with its battery replacement for higher capacity. As the headset's charging function had gone awry (always zero watt on charging) I had to implement a new charging capability and port for it with the PCB board in separation from its own one.
The headset's charging portion of circuit seemed to had been burnt for some reason I had been unaware of. All have been going fine and better ever since the fix. A quality charger board item.

LM2596 Step-down DC to DC Adjustable Buck Converter Voltage Regulator
Works fine without any malfunction. Tested with 12V 2A DC adaptor and I could adjust the voltages in a range of 10V down to 4V visibly. On account of my tester's limitations on their display (not the flaws of the tester's as they do not take powers for display from external sources), the remaining lower voltages could not be tested with my bare eyes. But with the pre-gone tests it could be safely presumed that those would also be right.
Tested mainly down-stepping 12V input to 9v and 5v outputs respectively and all went OK. All other voltage points also worked fine but it wasn't easy to pin-pointedly adjust a desired value on the spot as the voltage points seemed to had been divided very near each other for precise adjustments, which is good.

I tested it for 5 volts step down with solar panels of 5.5V 1W capacity and it has been proved to be working fine without flaws or defects.
Cost-effective.

Bluetooth Audio Receiver Transmitter Music Stereo Adapter
It includes a short helpful manual illustrating it in simple and bright ways, in French, German and English. It is nicer that it has its own rechargeable battery inside itself despite the fact that it includes TX mode which could deliver Bluetooth signals to various sound devices. I bought it mainly for this reason that it could make a wired playback device a perfectly wireless portable one.
- Transfer(TX) Mode: Tested with a now aged COWON D2 music player which has ample bass ranges. It worked well with S20 Bluetooth ear-set. The LED on the center of it blinks slowly in red.
  A little demerit is that it involves a bit of noise while idle, which is hardly being perceived while playing-back something. Small enough to be simply ignored for a few seconds between playing sound streams.
- Receiver(RX) Mode: Tested with wired little speakers and all went fine. The LED now blinks in blue.
Charge starts with 5V 0.2A (= 1Watt) and finishes in about 1 hour and 30 minutes. It would be better if it gives any signal minutes before closing itself off from battery depletion.
Battery capacity has been proved to be about 190~200mAh as described. (battery capacity as declared) It has lasted for 8 hours and 20 minutes without interruptions or any halt in RX mode.
It is recognized as 'BT-01' in RX mode. It lasts one or two hours less in TX (playback device to Bluetooth-capable) mode than in RX(Sound output device to Bluetooth-capable) mode. A cost-effective useful item.

DC1.8-15V PWM Speed/Dim Controller Potentiometer (on/off)
Tested with a 5V 2A DC adaptor which isn't of good quality but it worked fine with it. Dimming an LED light went on till the end without any error or clumsiness. Turning its adjustment knob till the end counterclockwise turned off the light completely.
It was felt there was a tiny switch inside the controller to turn its power off. No defects found except for the late delivery way behind the schedule.

I have installed it inside a static lamp as scheduled, which lit and worked fine powered by a single 18650 battery of 3.7v. And it worked way finer than what I had expected. A quality product with cost-effectiveness and a good buy of two at once.

10PCS of 1S 3.7V 3A Li-ion BMS PCM Battery Protection Board
All 10 pieces have arrived safely in an intact state. It wasn't easy to solder +/- wire ends on the battery +/- nodes respectively. It seems to be working fine. Anyway a good buy with cost-effectiveness.

Over-charge / under-discharge protections work fine respectively. I have already used five of them and all have been working fine without defects. And no electrical short curcuits occurred during every use or application of them. Optimistic for next buys.

Solar Panel Dual USB Voltage Controller Regulator Charger (5V, 3A)
Not any screws were included. Only the parts for the product were there. Thus I had to use my own spare screws. M 2.0 of length 6mm was the right size for the missing screws.
I tested it with a DC adaptor emitting variable voltages from 3V to 12V and it has been proved to be working fine in all the tested ranges. It turns off itself with way lower voltages than 5 volts, which is right for the gadget. No malfunctions or flaws from the product itself were detected.
It is rather quite effective and stable with user-friendly interfaces. It helped 4 solar panels (5.5v, 1W total capacity) accumulate about 710mAh of solar energy in about 4 hours and 50 minutes as shown in the images. It would have been a good buy if all the screws had accompanied it.
It works finest of all three similar kinds I've tried.

Handheld Mini USB Electric Drill
Well-made, robust, sturdy, powerful and handy product. Works fine even with energy source of a supplementary power bank. It has got right spinning speed and moderate power (torque) to drill tiny holes easily on a plastic plate.

It could create holes fast on a metal plate. The drill bit kept being stuck several times while drilling a metal plate but the task went on without delay as it started spinning again with a small touch on any part of the surface being drilled. As its spinning speed is high it was possible. Very handy and useful.

I customized it later for better handiness regarding its switch.

3.7V Lithium Battery Capacity Indicator 4.2V Blue Display Module (1s~8s)
A Choice item. As declared has it been delivered before 10 days passed with other two AliExpress Choice products. Only the capacity indicator module itself was there in a sealed transparent blueish vinyl bag. I have tested it for a single cell battery and all results have been proved to be fine.
It has got plenty of flexibility as it supports 8 types of serial connections maximum which could be selected respectively via soldering joining or disjoining two points on its back board. A good cost-effective buy at about almost a single dollar.

Tested it for 3 batteries in serial connection and proven to be working fine. Obviously it is not for precise detection but for quick referring to what has left currently of the batteries'.

Metallic Power Bank Case for Single 18650 Battery(5V 1A)
It has looks that is a bit chic but not quite, i.e., sleek specifically for its cylindrical cover material, thus good to be looked at. Works fine without major defects. Very little misplacement of its inner body containing its main module was detected and corrected instantly by myself with a flat screw driver.
It differentiates charging and discharging tasks by colors: The LED color blinks in red when the power bank itself is being charged and in blue when it charges other devices. Quite good for discernibility's sake and thus user-friendlier. A cost-effective product with user-friendliness and good looks. What has left to be checked further now is its durability.

USB Type-C Power Bank Case (5V 2A, 18650 x 2)
Short-click on its button turns it on and double-click on it turns it off.
Its LED light on its upper front face turns on and off with a long-click on its button for 3 seconds.
It charged itself and other gadgets too by about 10 Watts as declared in its descriptions. Overcharge/under-discharge worked correctly: Automatically cut the current flow right on reaching its full capacity while charging itself and turned itself off before the batteries drained out while charging other gadgets or devices.
It is not recommended but it could accommodate protected 18650 batteries also inside it. It also has four tiny LED dots on its front cover to show the currently available current amount of batteries. Its quality is rather superb for its price.

Mini Stainless Electronic Scale (1Kg)
Its cover and body are made up of plastic and its measurement plate is of stainless steel. Its height(18.mm) was twice as thick as I have thought of. Requires two good AAA batteries for it to work right. Using some unstable low quality batteries causes wrong weights to be displayed.
Measurements work fine if an object whose weight is being measured is placed at the center of the scale plate. Wrong placement of one may well cause some discrepancies.
I found out with several measurements that a tiny mismatch could occur depending on the position and the contacting dimension on the plate of an object whose weight is being measured. The more the contacting dimension of an object being measured, the more precise would its weight be measured. It turned itself off when no activities were detected exactly in a single minute.
