USB-C PD to NP-F550 Dummy Battery Coiled Power Cable - Compact Power

In this review the focus is on a practical accessory for shooters and monitor users: a USB-C PD to NP-F550 dummy battery coiled cable that lets cameras and monitors run from PD power sources. The bottom line is simple: if you use Sony NP-F550/ F770/ F570/ F970 cameras or Atomos Ninja V, Shinobi or Shogun 7 monitors and need longer runtime without bulky batteries, this cable delivers a reliable, lightweight alternative that converts USB-C Power Delivery into a 7.4V camera feed. It is best for users who already carry USB-C PD chargers or power banks and want a compact, coiled cable that keeps power flowing during long shoots.

Key Features

• Wide compatibility: Works with Sony NP-F550, F770, F570 and F970 style devices and powers Atomos Ninja V, Shinobi and Shogun 7 monitors for extended operation.
• PD-capable USB-C input: Accepts USB-C Power Delivery chargers and power banks so you can use modern PD supplies instead of camera batteries.
• 7.4V, 3A output: Provides a steady 7.4V, 3A output to keep cameras and monitors running without drops in power under typical loads.
• Indicator light: Built-in LED turns green when inserted into a PD-capable USB-C socket with 9V/12V output so you can quickly verify correct power negotiation.
• Coiled, stretchable cable: The cable spans roughly 15.7 in (40cm) collapsed and stretches to about 31 in (80cm) for flexible mounting and tidy cable management.

Who It's For

This cable is aimed at photographers, videographers and content creators who use Sony-style NP-F batteries or Atomos monitors and want to replace or extend battery life with USB-C power. It is especially useful on location when you carry a PD power bank or compact PD charger and prefer a lightweight, coiled cable to bulky V-mount systems.

Operators who require absolute plug-and-play support from every USB-C source should check their charger or power bank supports PD and 9V/12V negotiation, since the indicator will remain off if the socket only supplies 5V. If you need higher voltage rails or studio-grade continuous power, a dedicated battery plate or AC adapter may be more appropriate.

Pros & Cons

Pros

• Converts USB-C PD to a stable 7.4V 3A output compatible with Sony NP-F style devices.
• Indicator light makes it easy to confirm PD negotiation with compatible chargers.
• Coiled design keeps the cable compact while permitting extra reach when needed.

Cons

• Will not indicate power when used with USB-C sockets that only provide 5V, limiting compatibility with non-PD chargers.

Our Verdict

The USB-C PD to NP-F550 coiled dummy cable is a solid, cost-effective way to power NP-F style cameras and Atomos monitors from modern USB-C PD supplies. It is good value for run-and-gun shooters who already rely on PD chargers or power banks and want a neat, coiled cable with a clear indicator to confirm PD negotiation. For studio setups needing heavy continuous draw or legacy 5V-only USB sources, consider a dedicated power solution instead.
