Electronics and technology blog    /    Materials for October 2019 year

I've reviewed a lot of batteries, including high-capacity ones, but one interesting "fellow" had never been tested. Thanks to one of my regular readers, I now have it in my hands, and today I'll be taking a look at the Sanyo NCR18650GA.

Some time ago, the ambitious Beelink GT-King Pro TV box was unveiled. Essentially, it’s an updated version of the Beelink GT1-K, and today I’ll take a look at this new model. As usual, I’ll inspect it, take it apart, run some tests, and share my conclusions.

The latest model of adjustable power supply—or, more precisely, a converter for building one—has appeared in the well-known RD official store. This post is something of a preview, since I don't have one in hand yet. But I'll have a question about that at the end of the post.

I came across a faulty power supply and decided to jot down a note about repairing it, and while I was at it, answer a few questions people ask me, using a real example, so to speak.

This is the second part of the saga, “a battery tester for a friend,” and today I’ll be talking about changing the output voltage of the power supplies and connecting them in series.

After reviewing so many batteries, I decided to bring them all together in one big article. No unnecessary information here—just inspections, tests, comparisons, and brief comments on any noteworthy features observed during testing. Warning: this page uses a lot of data!
