Anything you put them in that can charge while in use won't work. People try them in solar lights all the time and are frustrated and write reviews about the failure. This points out they don't understand how they work.
As long as you understand that, go experiment.
If it's worth the trouble to charge them vs change them more often, might be worth a shot
See this review: https://www.amazon.com/gp/custome...tl?ie
These are more like 1768 to 2010 mAh @400mA current from one review.
Look up eg "aa power supply adapter" or "battery eliminator"
Again: pretty limited use cases but for where it's useful it's magick lol

I find that the mAh ratings of these USB batteries are inflated, and don't match up to quality NiMH batteries.
