Another power supply, and Sanmim again—but this time it’s a 50 W model, somewhat similar to the Meanwell LRS-50-12, which I reviewed just recently. In short, it’s a very interesting power supply.

More batteries sent to me by a blog reader. This time, though, we're looking at the very common 32700 form factor. I've had batteries of this size before, with various capacities, so I'll not only show you the new ones but also compare them with the previous ones.

Another power supply I bought at the Kharkiv Cosmodrome. It's been sitting around for a long time; somehow I never got around to showing it. But now I've finally caught up a bit with the day-to-day stuff and tested it.

These are the third batteries I've received from a reader, and this time they're from the relatively well-known BAK. Sure, they're not Samsung or Murata, but BAK is still a recognizable name.

The second set of batteries from a group shipment sent by one of my readers. This time they’re some no-name (at least to me) Gotion/Guoxuan cells, but as it turns out, they’re actually quite interesting.

Another compact power supply from a fairly well-known manufacturer, this time rated at 12 W. The short version: I was impressed.

It's been a while since I wrote a review. I've been pretty swamped lately with work on new electronic loads. But a little while ago, one of my readers sent me several different types of batteries to test, and today I'm reviewing the first ones.
