The Deluxe Power Grip for Canon 5D Mark III from Vivitar is a battery grip designed for use specifically with the Canon EOS 5D Mark III digital SLR camera, and accepts one or two Canon LP-E6 batteries. With two batteries installed, your shooting time is effectively doubled. In addition, the Deluxe Power Grip can utilize 6 AA batteries and comes with a battery tray designed to hold 6 AA/LR6 batteries.

The design of a battery grip offers a comfortable and secure way in which to hold your DSLR, especially in the vertical position. And the Deluxe Power Grip comes with an alternate shutter release button, ON/OFF switch, AF point selection/Magnify button, AE lock/FE lock/Index/Reduce button, and main dial to facilitate shooting when held vertically. The grip is designed with anti-slip rubber grip to further improve handling, a tripod socket to mount your camera directly to a tripod, and a wonderful touch: a holder for the camera's battery door so as not to lose it when the battery grip is installed.
