The Hollyland D-Tap to DC Power Adapter Cable (Model: HL-DT02) is an official factory-spare power cord engineered to drive Mars and Cosmo series wireless transmitters or receivers directly from professional, high-capacity cinema batteries.
On a busy film set, swapping out standard NP-F style batteries every few hours can slow down your workflow and disrupt your camera setup. This adapter cable allows you to consolidate your power management by tapping into your rig's main V-Mount or Gold Mount battery system. This provides your wireless transmission gear with hours of uninterrupted runtime while stripping away unnecessary weight from the camera cage.
Core Electrical and Structural Features
-
Continuous Production Power Distribution: Connects professional V-mount, Gold mount, or cinema-tier baseplates directly to your wireless setup. It allows you to run your image transmitters or director's monitors for full production days on a single master power source.
-
Premium Gold-Plated D-Tap Male Pin: Connection Terminal A features a rugged, industry-standard male D-Tap (P-Tap) interface. The internal gold-plated pin layout provides clean electricity transfer and guards against arcing or voltage sag under heavy loads.
-
2.1mm DC Barrel Connector: Connection Terminal B features a standard $2.1\text{mm}$ inner diameter male DC barrel plug. It slides firmly into your Hollyland hardware's native power port, ensuring a reliable fit that prevents intermittent power cuts from vibration.
-
Tough, Flexible 2-Foot Jacket: The cable is constructed with a highly pliable outer insulation jacket measuring 23.6 inches (60 centimeters) in length. This gives you plenty of room to route the cable through complex camera cages without leaving long, dangerous loops of slack that can catch on nearby gear.

On-Set DC Power Polarity Warning: Always double-check the physical alignment arrow or "+" icon on the D-Tap plug housing before sliding it into your battery's accessory socket. D-Tap connectors are D-shaped to prevent backwards installation, but lower-quality or well-worn battery ports can still allow a forced reverse-polarity connection. Forcing a D-Tap connector in backwards can bypass the safety grid, causing a short circuit that can instantly damage your wireless transmitter's internal electronics.
