Make sure you always have power to burn with the AC-VQH10 AC adaptor/charger. This adaptor is compatible with both InfoLITHIUM® P and H Series batteries. And since this adaptor provides super quick recharging with your InfoLITHIUM H Series batteries, you'll never miss an important shoot. The AC-VQH10 also features sequential charging which automatically starts charging your second battery once the first battery is fully charged. The supplied DC cable enables the AC-VQH10 to function as an AC/DC adaptor. Plug the other end of the DC cable into your camcorder and toggle the switch on the top of the AC-VQH10 to stop charging the batteries in the bays and begin charging the battery within your camcorder.
