Have you ever been annoyed with the fact that you need to buy again and again batteries for your gadgets?
Well, these AA batteries are pretty old technology but the sure thing is that they are going to be in use in the future.
The good thing is that you can buy rechargeable batteries but, most of them also require a charger. And when you have to carry with yourself a pack of batteries and a charger all the time, it just doesn’t work so well.
However, USBCell has came up with a solution which definitely solves the problem. They created AA rechargeable batteries which can be charged via USB port! Isn’t that amazing? Just plug them into your computer or any kind of USB charger and let them charge for about 5 hours. And that’s it.
