Energizer AA & AAA Battery Charger w/4 AA Batteries

This charger works great. I've moved from wired mice to wireless so I wanted to have rechargable batteries nearby so I don't have to continuously purchase new AA batteries all the time. The batteries charge rather quickly and the device lights up to let you know how charged they are based on color. If you aren't completely knowledgeable about eloctricity and how it works it's important to look at the instructions included as the batteries have to be placed in a specific way to actually charge. So long as instructions are followed then it's easy peazy. I also loved the fact that this product was not only a charger but also came with rechargable batteries instead of making me buy them seperately and all for a really good price.
