Portkeys BD1 NP-F Dummy Battery with D-Tap Cable

SKU CH-56QD-ZZ3XX

A dummy NP-F battery with D-Tap cable powers monitors and transmitters simultaneously via dual-orientation NP-F plate, USB-C and barrel inputs

  • Powers monitor and transmitter simultaneously via dual NP-F output
  • Accepts 7–16.8 V barrel and 9/15 V USB-C sources
  • D-Tap cable draws from professional V-mount or Gold-mount packs
  • Removable double-sided NP-F plate reorients in four directions
  • Compact 2.8×1.6×1.5 in body weighs 2.7 oz

Power Solution for Portkeys Monitors

The Portkeys BD1 NP-F dummy battery replaces a standard NP-F pack and connects to professional D-Tap batteries via the included Type-B to DC cable, delivering continuous power to compatible Portkeys monitors during extended shoots. It suits camera operators who need reliable mains-free runtime without swapping internal cells.

Upgrade from Internal NP-F Batteries

The jump is worth it when a shoot exceeds the capacity of a single NP-F battery or when hot-swapping power sources is impractical, because the D-Tap link draws from larger V-mount or Gold-mount blocks that last all day. It is not for users who only need a spare NP-F cell or who rely solely on USB-C power banks.

Build Integration and Mounting Flexibility

The unit measures 2.8 by 1.6 by 1.5 inches and weighs 2.7 ounces, so it fits inside compact rigs without shifting the centre of gravity. Dual inputs accept 7 to 16.8 V through the barrel connector or 9, 12 and 15 V at 2 A via USB-C, freeing the monitor’s native battery slot for other accessories. The removable double-sided NP-F panel allows downward, upward, leftward or rightward cable routing to keep cables clear of matte boxes and follow-focus gears.

Questions about this item

What are the exact dimensions of the dummy battery so I can confirm it fits my NP-F plate?

The unit measures 2.8 by 1.6 by 1.5 inches and weighs 2.7 oz.

How do I connect the D-Tap cable and which input do I use on the dummy battery?

Plug the D-Tap Type-B end into your battery plate and the DC barrel connector into the dummy battery's 7-16.8V coax input.

Will the USB-C PD port need a specific charger profile to keep the monitor running?

The USB-C input accepts 9, 12 or 15V at 2A; use a PD charger that can negotiate one of those voltages.
