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.

There are a few discounts on various soldering and welding tools; this may be useful to someone.

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.

Banggood is running some promotions right now, with stars to collect, and while browsing I kept coming across this impact wrench at what seemed like a reasonable price. I don't actually need one, but a few times I nearly bought it. I thought it might be useful to someone.

I think many of my readers remember that I often test batteries, and for quite a while I've also had my eye on a dedicated battery tester. Yes, friends, today we're talking about the EBC-X electronic load and tester, which I finally bought :)

Like many people, I have a WiFi router at home for tablets, laptops, and lately various IoT (Internet of Things) devices. But because of the apartment's layout and the less-than-ideal placement of the router, the connection is poor in some areas, so I decided to improve things a little by installing a WiFi repeater.

Discounts on both models of Ruideng adjustable voltage converters

Last fall, a very interesting adjustable voltage converter, the RD6006, went on sale. It stood out from previous models with its large display, convenient controls, battery charging function, and WiFi connectivity. But discussions soon started: 60 V is certainly nice, but 6 A is a bit on the low side. The manufacturer replied, “Don’t worry, a more powerful version will be out in about six months.” In fact, it took longer, mostly because of the virus, but the manufacturer didn’t abandon development, and today I’m reviewing the version with an output current of up to 12 A.

Lately, I’ve been seeing quite a few reviews where people either build spot welders or use them in their projects to assemble battery packs. I’ve got one of these devices myself now, though it’s quite different from the ones I’ve seen before.
