Tether Tools Case Relay Camera Adapter CRN5 for Nikon EN-EL9a Battery

Tether Tools Relay Camera Coupler CRN5 for Nikon EN-EL9a battery

The Tether Tools CRN5 Relay Camera Coupler takes the place of the Nikon EN-EL9a battery in the camera and, together with the Case Relay Camera Power System (sold separately), keeps the camera powered continuously from an external 5V USB battery pack or from wall power through a USB AC adapter. The coupler is simply an insert for the battery cavity: it contains no battery and holds no charge.

It suits time-lapse photography, photo booths, video production, power-hungry LiveView shooting and long days on set. Because Case Relay has its own internal 1200 mAh backup battery, the external battery pack can be hot-swapped without the camera losing power.

Key features

• Insert for the camera battery cavity, contains no battery
• Continuous power from standard 5V USB power banks or wall power via Case Relay
• External battery can be hot-swapped without powering down the camera

Notes

• Insert the coupler into the battery cavity and close the battery door completely, letting the cable exit through the rubber trapdoor: the door must be fully closed for the system to work properly
