The Canon LC-E6 battery charger is designed for use with the LP-E6 battery pack, which powers the Canon EOS 5D Mark II, 5D Mark III, 7D and 60D digital SLR cameras. This unit can be used to charge a battery for these cameras from a standard electrical outlet. It operates on 100-240VAC power. Its 2-prong US plug goes directly into a wall outlet, so no power cord is required.
