With this GoPro-friendly Action Battery Grip (and mount) you can triple the battery life of your camera while keeping things lightweight and compact. Don't worry about running out of power midway through a shoot. You even can use it to charge your smartphone or any other accessory on location (and use your smartphone to shoot video).

Triple the life of your action cam. This grip has a built-in battery that can re-charge your action camera fully two times while you’re out on your adventure.
Comes with USB charging cable. A shorter cord makes it easy to charge your GoPro while in use. Even charge any accessory – including your smartphone.
Resizable tether for an added and secure hold. The removable wrist strap provides extra security against drops.
Bottom 1⁄4"-20 mount for numerous mounting options. Mount to a tripod for an eye-level, hands-free set-up, or to the UltraPlate 208 to create a powered mini rig.
Works with any action cam with 1⁄4"-20 design. Comes with built-in, standard GoPro mount and thumbscrew, plus includes a top pin for use with any other action camera (1⁄4"-20 screw).
