The GoPro Battery Eliminator with Wall Adapter from Core SWX is designed to provide a secure way of powering a HERO3 or HERO3+ action camera from an external USB power source. The GoPro's form factor may be a major part of the camera's appeal, but it limits the effective battery life to what an internal battery can provide. Where the camera is readily accessible, it is simple enough to keep spare GoPro batteries on hand and simply swap out as needed. However, especially as a growing number of professional filmmakers are drawn to the GoPro's versatility, the camera is increasingly finding itself placed in spots that are difficult to access for a quick battery change. The GoPro Battery Eliminator employs a similar concept to a DC coupler that you may be familiar with from camcorders and DSLRs, using a coupler plate that mimics the original battery, but with a 10' power cord that terminates in a USB type A male power connector.
