Digital Power Grip f/ Nikon D7100 Camera

The Bower Professional Battery Grip for Nikon D7100 Camera provides the power you need for the Nikon D7100 SLR digital camera. It adds to the power by using one EN-EL15A rechargeable, high-capacity battery, or 6 AA batteries. In addition, the battery pack provides a vertical shutter release that makes holding the camera in the vertical orientation as easy and secure as in the horizontal position. The included EN-EL15A rechargeable battery will provide hours of uninterrupted shooting, and in an emergency, rechargeable or alkaline AA batteries can be used.
