You would have thought someone would have come up with idea a long time ago but apparently not. These USB rechargeable batteries, available from Chinavision, are a gadget-geeks dream (and at GadgetHeat we have plenty of those).

.

The AA batteries can be used for all your standard gizmos such as remote controls, cameras, torches etc. and when depleted, you can just lift the lid on the USB rechargeable batteries, plug them into the nearest USB port and watch these bad boys recharge themselves.

There is even a LED indicator that lights up when the batteries need charging and switches itself off when they are full. The USB Rechargeable batteries retail at $20.40 for a 4 pack with further discounts for bulk purchases from Chinavision.
