Sometimes, when looking at tool batteries, I wondered why no one had combined one with a power bank. Yes, I’d come across adapters that offered a similar feature, though only in one direction: discharging. But recently I saw something in the TPcell store that really caught my interest: a battery with a built-in power bank.

Back in the spring, I bought a pair of tweezers on sale (three items for next to nothing), tried them out, and ended up tossing them in my desk drawer. Now I’ve finally found a little time to tell you what they’re like, why I don’t use them, and how they compare with my main pair of tweezers, which I bought quite a while ago.

Not long ago, I spotted a new product from Atorch, got interested, contacted the manager, negotiated a discount (unfortunately, not a very big one), ordered it for review, received it, and now I’m sharing it with you.

Not long ago, I posted a couple of reviews—one of a voltage converter and one of a power supply—and mentioned that I’d bought them specifically for a new version of one of my projects: a battery tester. Today, I’ll tell you a little about it.

A quick look at a handy little gadget. I bought a few to have on hand, and maybe I’ll include one with one of the new loads.
