The LC-E4N Battery Charger from Canon will charge two separate LP-E4N battery packs--at a rate of 120 minutes per battery. The charger plugs directly into AC outlets, and includes a CB-570 cable adapter which can be plugged into a DC car socket. When in use, the charger performs battery capacity calibration so that the remaining battery level can be indicated accurately when used in the EOS-1D X camera.
