Okay product
This is very small, and you can only charge name brand batteries, but since I had a bag full since we do not have a recycle place where I live, I have used successfully for AA And AAA batteries, great if you run out of batteries . Have no idea how long will last, much more lightweight than I expected, but so far has been usefull.  It tells you if not rechargeable. I got caught with no batteries when had a 19 hr, power outage, so this what I took the chance and purchased, I can not drive any longer and have to stay prepared. Satisfied with purchase.
