The SmallHD D-Tap Power Adapter for 500/700 Series Monitors lets you use an external power source with your 500- and 700-series onboard monitor. The adapter is shaped like an LP-E6 battery and mounts to one of the monitor’s battery slots.
This rental includes a three-foot D-Tap-to-barrel power cable, which connects the adapter to many batteries’ D-Tap outputs. This powers your monitor for longer than LP-E6 batteries.
