The Tenergy Smart Charger for AA and AAA Batteries (Tenergy T-3150) is a compact charger that also works for AAA batteries. Its universal input (AC 110-220V 50/60 Hz) coupled with its small size makes it good for travel and it is ideal to use with batteries for digital cameras and pocket PCs as well as radio control toys such as the Sumo RC vehicles from Redcat Racing. A temperature sensor avoids battery overheating and a negative delta V cut-off also exists.
