D-Tap to Double-Sided NP-F Dummy Battery Adapter - Thin Version

In this review the D-Tap to Double-Sided NP-F550/970/570/770 Dummy Battery Power Adapter (Thin Version) is examined for users who need a compact way to power monitors, wireless transmitters and small devices from a single V-mount source. The main reason to consider it is its three-output design that lets a pair of NP-F style slots share an 8V 8A, 64W supply while offering a Type-C PD port for up to 36W to run cameras or phones, keeping a rig neater and reducing battery clutter.

Key Features

• Dual NP-F Outputs: Two-sided NP-F interfaces share up to 8V 8A, enabling simultaneous power for a monitor and a wireless video transmitter without extra mounts.
• Type-C PD Port: Built-in Type-C output supports PD 5/9/12V at 36W, useful for powering small cameras or charging phones when on set.
• Compact Thin Version: The thin form factor is designed for device battery slots up to 7mm deep, making it suitable for slimmer monitors and transmitters.
• Durable Construction: CNC aluminum alloy frame and replaceable power cable with nut deliver a sturdy, serviceable adapter that tolerates regular rigging.
• Protection Circuitry: Built-in reverse input/output, high voltage and overload protection reduce risk to connected equipment during continuous use.
• High Efficiency: High conversion efficiency (claimed 96%) keeps heat low and allows sustained power for long shooting sessions.

Who It's For

This adapter is a practical choice for camera operators and content creators who run small on-camera monitors, LED lights and wireless video transmitters together and want to power them from a single V-mount source. It suits users who prioritize a compact setup and fewer separate batteries and mounts.

It is less appropriate for users whose device battery slots are deeper than 7mm (they should buy the thicker version instead), or for anyone who expects it to directly drive cameras that require decoded batteries, since the unit is not a camera battery substitute in that sense.

Pros & Cons

Pros

• Allows simultaneous powering of monitor and wireless transmitter from one V-mount feed.
• Type-C PD option adds flexibility to power small cameras or charge phones on set.
• Solid CNC aluminum build and replaceable cable increase durability and serviceability.

Cons

• Fit is mixed across customers - some devices such as certain monitors may not accept the thin version despite similar battery form factors.
• Not a decoded camera battery, so it cannot act as a full camera battery replacement for all cameras.

Our Verdict

The thin D-Tap to double-sided NP-F dummy battery adapter is a useful tool for anyone who runs a monitor and wireless transmitter and wants to centralize power from a V-mount source. Its three-output layout, Type-C PD port and sturdy CNC construction offer clear value for small rigs, but buyers must confirm their device slot depth and understand it is not a decoded camera battery. For the right setup it simplifies power management and reduces battery swaps on shoots.

Frequently Asked Questions
