We've all used AA rechargeable batteries. They are great, save you money, reduce waste, but they all come with that bulky charger -- often not at your fingertips. But USBCELL AA rechargeable batteries are a whole different story.

They can also be recharged hundred of times but no charger is required as they charge from any USB port. Pop off the lid, plug them in a USB port and within 5 hours, they are charged to over 90% of capacity!
