When you’re in the heat of the action, you don’t want your camera’s battery giving out on you at the wrong moment. That’s what the SP-Gadgets Powerbar Duo is for. This handy mobile power source and charger lets you recharge any two HERO3 or HERO3+ batteries and a large variety of US devices.
Recharge your GoPro® battery or your USB device on the go or plug the Powerbar into the wall socket to charge its own battery in addition to any two HERO3 or HERO3+ batteries plus your GoPro®’s battery. The Powerbar has enough power for charging two batteries or can power USB-chargeable devices – so you can be sure you capture all of the action.
