This small charger can be tucked into the flap of your camera or recorder case. It occupies less space than a pack of cigarettes. There are only two negatives, which are not really negative once you understand how the device works. Two batteries must be in the left or right pair of holders to charge. Also, there is a switch inside which MUST be in the 110v position to charge right. Mine came in the 220v, and I can see how someone might just use it and think it's broke. If you're in the U.S., and it's set to 220, it will not charge the batteries correctly making you think it's not working right. OK, now that we have that said, I had no problem with the device. I purchased it for my minidisc recorders, and it charged up all four AA batteries in about 25 minutes to full level. The bonus to this charger is there is no wall-wart or long cords to tangle in your case. Just slip batteries in, and plug the charger into the wall. That it!
