Brief Instruction:
This cable is designed to power the Black Magic Pocket Cinema Camera from a D-Tap port found on many high-capacity V-Lock or Anton Bauer batteries and also on some power distributor systems. 
The other end plugs into the Black Magic Pocket Cinema Camera’s external power port. 
The camera connector is a very thin barrel jack(2.35mm x 0.7mm) and is right angled to reduce the likelihood of damage to the power port if the cable is snagged.
 
Cable Length: 110cm.
