If you use only AA and AAA rechargeable batteries, the Photocam Mobil charger from ANSMANN offers great performance and flexibility, wherever you need to recharge your batteries. It uses microprocessor electronic charge control, rather than a fixed-time charge cycle to ensure you can safely top up partly charged batteries without the risk of damage from overcharging. The four included 2400mAh NiMH AA batteries pack all the power you need for very demanding applications, such as top range digital cameras. The charger's 1400mAh AA charge current is strong enough to fully charge in the included batteries in about 2 hours, whether plugged in via the universal voltage (100V-240V) mains adaptor. The charger will also work with NiMH AAA batteries, but does not work with NiCd batteries. It charges two or four batteries at a time
