The LC-E19 Battery Charger from Canon will charge two separate LP-E19, LP-E4, or LP-E4N battery packs. LP-E19 batteries charge at a rate of 170 minutes per battery, while LP-E4 and LP-E4N charge at a rate of 140 minutes per battery. It plugs directly into AC outlets and includes an AC adapter.
★★★★★ Charges both my LP-E19 batteries reliably and quickly, and the built-in AC plug makes it super convenient. A solid, well-made Canon charger that does exactly what it should.
