TETHERTOOLS Case Relay Coupler Compatible with Sony Battery NPFW50

The Relay Camera Coupler combined with the Case Relay Camera Power System provides constant, uninterruptable power for your camera and is perfect for time-lapse photography, photo booths, video production and power-hungry LiveView shooting or any long day on the set. Need more power? Hot swap in another power bank and continue shooting while never losing power to your camera.

Simply insert the Relay Camera Coupler directly into the camera battery port, attach it to the Case Relay CPS and power your camera with the included Rock Solid External Battery Pack or an AC power source using an USB to AC wall adapter or use the ONsite D-Tap Battery with V-Mount. Because Case Relay also has its own secondary internal 1200 mAh battery, if your external battery runs low you can easily hot swap the external battery and not lose power to the camera.

• Insert Relay Camera Coupler into camera battery cavity
• Completely close battery door allowing coupler cable to exit through the rubber trapdoor
• Battery door must be completely closed for the Case Relay Camera Power System to properly function
