I've already explained how to turn an ordinary power supply into a charger, but for a long time I couldn't shake the thought that a charger should work more properly. Then I came up with the idea of making one that was not only proper and simple, but also based on the adapter board I'd already shown.

Given the current situation—or, more precisely, the lack of "power"—charging batteries has become a serious problem, preferably with fast charging. On top of that, I got the idea of building a small UPS for the refrigerator, which also needs a charger. I bought several LRS-350-12 power supplies for this whole project, but as you can imagine, things aren't quite as simple as I'd hoped :)
