Tether Tools ONsite Relay Camera Power System Kit with Coupler for Sony Cameras with NP-FW50 Battery

Power your camera continually, and without interruption, with the Tether Tools ONsite Relay Camera Power System Kit from B&H which bundles in a coupler for connection to select Sony cameras that use NP-FW50 battery packs. Equipped with a built-in 7.4V, 1,200mAh lithium battery and a 5 VDC input via USB, this system will provide power, while being connected to an external power source for a nearly constant source. When connected to a 2A USB battery pack or an AC adapter, the ONsite Relay can still be able to provide a constant supply of power to your camera, and thanks to the internal battery the system will support hot swapping of external power sources. An LED indicator light will shift from green to yellow to red to show battery percentage so that you will not accidentally lose power during a long time lapse or video production.
