I was recently looking for something on AliExpress, but got a bit carried away and started browsing all sorts of interesting products. Here are a few I’d like to show you today—maybe you’ll find them useful.

Vapcell batteries, part four: 16340, 14500 and protected 18650 sizes with built-in chargers
3-09-2020, 00:16
This is another installment in my series of reviews of Vapcell products, but this time they’re not just batteries—they have built-in chargers. That’s partly why I gave them a separate review, so they wouldn’t get mixed up with the others.
Battery for the Teclast Tbook 10S tablet
2-09-2020, 12:25
Three and a half years ago, I reviewed the Teclast Tbook 10S tablet. I really liked it, and it saw fairly heavy use for almost the entire time since I wrote the review. But after about two and a half years, its battery started to give out, and by the three-year mark, it was basically running only on mains power, so I decided to replace it with a new one.
Vapcell batteries, sizes 16340, 18650 and 21700

In the spring, I published two reviews of Vapcell batteries, both conventional lithium-ion and LiFePO4. Now I’ve got another batch of cells with this company’s logo. To avoid overwhelming readers with too many reviews, I split the batteries into several groups. Today I’m reviewing the first group.

It's been quite a while since I last posted a product roundup, so today I decided to make up for it. There won't be too many products, but I've tried to pick out ones that might be interesting, including some I've bought myself. That doesn't mean you can't share links to products you think might be interesting, too.

The second part of my introduction to Light Route products. In the previous part, I covered 60 W power supplies with 12 V and 24 V outputs. Today, I’ll be looking at drivers for powering high-power LED modules used in lights, floodlights, and street lamps.
6Y880 Spot Welder Controller and Various Other Components
Not long ago, I published a review of a board for building a simple spot welder powered by supercapacitors. Today, I’m continuing that series: I’ll tell you about a much more capable device and, along the way, build a welder based on it.

A friend recently asked me to test a small battery for quadcopters and similar toys. I was curious, so that’s how I came up with the topic for today’s review.
A quick look at a small pair of tweezers
I ordered some things from Taobao not long ago and needed something to fill out the package. I spotted these tweezers and ordered one to try, just out of curiosity. This is probably one of the shortest reviews ever :)
RPM-416 Electrical Parameter Recorder from Novatek-Electro
3-08-2020, 03:52
Today I'm reviewing a product that isn't exactly unusual, but is definitely quite rare. In general, based on my personal observations, the number of reviews of devices for industrial and specialized applications is close to zero, and with this review I want to help fill that gap a little. So today I have a rather interesting gadget on my desk with a complicated name: an Electrical Parameter Recorder.
A pair of 60 W power supplies rated for 12 and 24 V
31-07-2020, 02:08
I've reviewed quite a large number of different power supplies by now, but today's review is a little different. No, the power supplies themselves are much the same; the difference is the manufacturer. If I'm not mistaken, this is my first review of power supplies made in Ukraine.

It’s been a while since I posted a power tool review, and now I’ve got my hands on a cordless angle grinder designed for standard Makita batteries—and it also has a brushless motor. Today I’ll take a look inside, take it apart, run a few tests, and include a small bonus.
