Designed for today's "power hungry" HD-video SLR's and still cameras, our dual charger is the smart way to make sure you're always in power. Thanks to a unique intelligent circuitry and Interchangeable plates it charges up to two batteries (of same model or different) in the same amount of time, then "tops off" that charge without causing memory issues. If you want your shooting day to be about performance not power, keep our dual charger at your side.
