D-Tap to Double-Sided NP-F Dummy Battery Adapter - Compact Power

In this review the D-Tap to double-sided NP-F series dummy battery adapter is assessed for people who need a compact way to power field monitors, wireless video transmitters and small accessories from a single V-mount source. The biggest reason to consider this adapter is its three-way output design: two NP-F style outputs that share up to 8A at 8V and a Type-C PD port up to 36W, which keeps a run-and-gun kit streamlined and reduces the number of batteries and mounts required on a rig.

Key Features

• Double-sided NP-F outputs: Two NP-F style contacts allow simultaneous power to a monitor and wireless video transmitter without needing separate batteries, saving space on the rig.
• Three-way output: The two NP-F interfaces share an 8V, 8A, 64W capacity while a Type-C PD port provides up to 36W at 5/9/12V to power cameras or phones.
• Thicker version housing: The CNC aluminum medium frame in the thicker version provides a sturdy, reliable shell suited for deeper battery slots and repeated field use.
• Modular cabling: The power cable uses a nut and can be disassembled or replaced to meet different connector needs or to swap in a coiled cable for tidier routing.
• Protection circuitry: Built-in reverse input/output, over-voltage and overload protections increase safety and help protect connected devices during long shoots.

Who It's For

This adapter is aimed at independent filmmakers, ENG shooters and content creators who mount a monitor and a wireless video transmitter on a small rig and want to run both from a single V-mount battery. It fits users who appreciate the space and weight savings of consolidating power sources and who often work with NP-F style monitor mounts and compact transmitters.

It is not a direct camera battery replacement for models that require a decoded battery; the Type-C PD and NP-F outputs will not act as an internal camera battery for all cameras, so buyers who need guaranteed camera battery emulation should confirm device compatibility or select a purpose-built camera power solution instead.

Pros & Cons

Pros

• Consolidates power for monitor and transmitter, reducing the number of batteries and mounts needed on a rig.
• Type-C PD output adds flexibility to power a camera, phone or accessories up to 36W.
• Solid CNC aluminum construction and replaceable cable provide durability and serviceability.
• Built-in protection circuits and high conversion efficiency reduce heat and improve operational safety.

Cons

• Not suitable as a decoded replacement for all camera batteries; verify camera requirements before relying on it for camera power.
• The thicker version requires measuring device battery slot depth to ensure a proper fit.

Our Verdict

The adapter is a practical, well built option for creators who need to power a monitor and wireless video transmitter from one V-mount source while retaining a Type-C PD outlet for accessories. It delivers good value by reducing battery clutter and adding modular cabling and protection circuitry, though buyers should confirm slot depth and camera power requirements before purchase.

Frequently Asked Questions

Can this power a camera directly?
It provides a Type-C PD output up to 36W but is not a guaranteed decoded camera battery replacement; confirm your camera accepts external PD input or requires a decoded battery.

Which battery slots fit the thicker version?
The thicker version is intended for device battery slots with depth between 7mm and 12mm; measure the slot depth before ordering.

Are replacement cables available?
The adapter uses a removable power cable with a nut so you can replace it or choose optional coiled cable variants for different setups.
