A Battery Coupler acts as a dummy battery. By replacing your original battery and connecting this coupler to the low voltage output of either a Pegasus Powerbox or DSLR Buddy it will provide a more stable and consistent power source to let your camera operate all day and night long.

Note that the new version of the battery coupler includes a single cable ending in a male 2.1mm plug.

Photos of this product may not necessarily be the latest version.

Compatible with: A7 A7R A7S A7II A7RII A7SII and other cameras that use the NP-WF50 Battery
