Electrically powered firearm mounting rails are designed to provide electrical power to firearm accessories. A power clamp can tap into the rail electrical power and pass it to other items requiring electrical power. Principal among those items are firearm accessories having battery compartments and designed to be powered by batteries. The power clamp can be connected to power terminals in the battery compartment directly through additional circuitry, through modified battery covers, through false batteries, or through dummy batteries. In this manner, the need to install batteries in the firearm accessory is relaxed and the weight balance of the firearm improved.
