SmallRig D-tap to Dual-Sided NP-F Dummy Battery - Clean Power

In this review of the SmallRig D-tap to Dual-Sided NP-F Dummy Battery, the bottom line is simple: this adapter is designed for shooters who want to centralize power from a V-mount source and eliminate battery clutter on monitors and wireless transmitters. The reviewer found it particularly useful when running two NP-F style devices simultaneously while also feeding a Type-C device, with clear value coming from the real-time voltage readouts and the retractable cable that keeps setups tidy. It is not a camera-mounted power source, but it excels as a rig-level power distribution accessory.

Key Features

• D-tap to NP-F distribution: Allows one V-mount D-tap feed to power dual-sided NP-F devices so accessories share a single centralized battery.
• Quad-channel outputs: Four-way output shares 8V/4A (33W) so two NP-F devices and additional outputs can run concurrently without unexpected shutdowns.
• Type-C PD port: Supplies 5/9/12V at up to 33W to cameras or mobile devices for added versatility on set.
• Real-time monitoring: Two displays and an indicator light provide immediate D-tap input and NP-F/DC output voltage feedback for safe, visible power management.
• Durable construction: CNC aluminum housing with fire-resistant PC/PU materials and multi-layer protection helps prevent overheating, short circuits, and voltage faults.
• Retractable cable: Cable extends from about 39cm (1.29ft) to 139cm (4.56ft) to reduce tangles and accommodate varied rig layouts.

Who It's For

The SmallRig adapter is aimed at camera operators, gimbal pilots, and video technicians who run external monitors, wireless video transmitters, or NP-F style dummy batteries and want to consolidate power from a single V-mount source. It is especially useful on longer shoots where swapping multiple batteries would interrupt workflow.

Those who need a dummy battery that plugs directly into a camera battery compartment should look elsewhere, since this unit is a distribution module and explicitly cannot be inserted into a camera. It is best paired with external V-mount batteries and used as part of a rig-level power plan.

Pros & Cons

Pros

• Centralizes power to reduce battery and cable clutter across monitors and transmitters.
• Multiple outputs including dual NP-F sides, DC output, and Type-C PD give flexibility for various accessories.
• Transparent monitoring with two screens and an indicator light improves safety and confidence during shoots.
• Robust materials and built-in protections help ensure reliable operation in demanding conditions.

Cons

• The module is not designed to be plugged into a camera body, so it does not replace an in-camera dummy battery for run-and-gun setups.
• The device adds a small amount of bulk and connections to a rig compared with single-cable solutions.

Specifications

Our Verdict

The SmallRig D-tap to Dual-Sided NP-F Dummy Battery is a practical, well-built power distribution accessory for shooters who rely on external monitors and wireless transmitters. Its combination of dual NP-F outputs, a Type-C PD port, clear voltage displays, and a retractable cable make rig management easier and safer. For anyone consolidating power to a single V-mount source, it represents good value and reliable performance.

Frequently Asked Questions

Can this unit be plugged into a camera?
No. The adapter is a distribution module and cannot be inserted into a camera battery compartment; it is intended to power external accessories from a D-tap source.

What voltages does the Type-C port supply?
The Type-C PD port supplies 5V, 9V, or 12V at up to 33W for cameras or mobile devices.

How long is the cable when fully extended?
The retractable cable extends from about 39cm (1.29ft) to 139cm (4.56ft) to accommodate different rig layouts.
