Corn Electronics NP-FW50 Dummy Battery USB Cable 1.5 m 7.6 V 5 V 2 A camera battery

SKU CH-YEAC-SPZQK MPN NP-FW50

Powers compatible Sony cameras from a 5 V 2 A USB source through a 1.5 m cable with 7.6 V output and built-in protection

  • Extended shooting sessions with 1.5 m USB cable
  • Safe operation via short-circuit, over-voltage and over-current protection
  • Broad Sony compatibility from NEX to a7 and A6000 series
  • Plug-and-play USB 5 V 2 A input for power banks
  • Lightweight 62 g dummy battery replaces NP-FW50 pack

Power adapter for Sony cameras

This dummy battery replaces the NP-FW50 pack and draws power from any USB source that delivers 5 V at 2 A. A 1.5 m cable lets you keep a power bank in a pocket or bag while shooting. Built-in short-circuit, over-voltage and over-current protection guards the camera during extended sessions.

Suited for long takes and studio work

Videographers and event photographers who need continuous runtime without swapping batteries will benefit. Users who rely on the camera’s own battery contacts for weather sealing or who cannot tether to an external USB supply should look at a conventional spare battery instead.

7.6 V regulated output from USB 5 V 2 A input

The adapter steps the USB supply up to 7.6 V, matching the voltage the camera expects from an NP-FW50 cell. If your power source cannot sustain 5 V at 2 A the camera may shut down under load, so verify the charger or power bank rating before trusting it for critical work.

Questions about this item

Does the 1.5 m USB cable need any special care to avoid wear?

No special maintenance is required; avoid sharp bends or heavy tension on the cable and store it coiled loosely when not in use.

What stops continuous shooting first — the 7.6 V output limit or the 5 V 2 A input limit?

The 5 V 2 A input from the power bank is the first bottleneck; if the supply cannot sustain 2 A the camera will shut down before the 7.6 V regulator reaches its limit.

How warm does the dummy battery get during an all-day shoot?

The unit runs cool under normal use; the built-in short-circuit, over-voltage and over-current protection prevents excess heat, so it stays near ambient temperature during extended operation.
