Canon LC-E4 Battery Charger

Unlike the previous-generation battery charger, LEDs clearly indicate the LP-E4 battery's state of charge, with clear indicators printed on the charger to alert the user when a battery is fully charged. The battery charger can also be used to Calibrate LP-E4 battery packs – more on that in a moment. Like virtually all Canon chargers, the LP-E4 is a multi-voltage charger than can travel almost anywhere, needing only a plug adapter. AC voltage from 100v to 240v are automatically sensed, and no voltage converter is needed. The LC-E4 can charge two LP-E4 battery packs  simultaneously.
