USB Rechargeable AA Batteries
The batteries (1450mAh) will power any device you need them for, then when the time comes take them out, pop off the caps and insert them into a USB port for quick easy charging.
There is even a handy blue LED to show when the batteries are charging which turns off when they are fully charged.
