D-Tap to LP-E6 Dummy Battery Power Cable Adapter for SmallHD

In this review the POWRIG D-Tap to LP-E6 dummy battery cable is evaluated for filmmakers and videographers who need reliable run-time for SmallHD monitors. The reviewer found the adapter straightforward to use, with the single biggest reason to buy being its built-in LED display voltage that removes guesswork about battery state while powering a monitor directly from a D-Tap or P-Tap output. It is particularly useful on location where swapping camera batteries is impractical and a pro battery pack is available to supply continuous power.

Key Features

• Anti short-circuit design: Protects your monitor and battery by preventing accidental shorts when connecting and disconnecting the cable on set.
• LED display voltage: Shows the output voltage in real time so you can monitor battery health without additional tools.
• LP-E6 compatibility: Presents a dummy LP-E6 battery connection so SmallHD 501, 502 and 702 monitors accept power as if from a camera battery.
• D-Tap input: Draws power directly from a pro battery D-Tap or P-Tap output for extended run times during long shoots.
• DC 7.2V output: Supplies the correct nominal voltage expected by SmallHD monitors for stable operation.
• 70cm max length: Offers a practical reach at roughly 27.5in to position the monitor and battery comfortably on rigs.

Who It's For

This cable is aimed at camera operators, gimbal pilots and location shooters who already use pro batteries with a D-Tap output and need uninterrupted power for SmallHD monitors. It is ideal when the monitor must run for hours and swapping multiple LP-E6 batteries would be inconvenient.

Those who should look elsewhere include users without access to a D-Tap or P-Tap power source or shooters who need a multi-voltage regulator or USB power options, as this adapter is designed specifically for DC 7.2V output and LP-E6 form factor.

Pros & Cons

Pros

• Provides a clean method to run SmallHD monitors from professional battery packs using a standard D-Tap.
• Built-in LED voltage display keeps you informed of battery voltage at a glance during shoots.
• Anti short-circuit protection increases safety when connecting power on set.
• Compact form and 27.5in length give practical reach for most rig layouts.

Cons

• Outputs a fixed DC 7.2V and therefore is not a universal regulator for other voltages or devices.
• Only includes the cable connector; no additional mounting or weather protection is provided.

Frequently Asked Questions

Will this power my SmallHD 702 monitor?
Yes, the cable provides a DC 7.2V LP-E6 dummy output designed to power SmallHD 501, 502 and 702 monitors.

Does it include a battery or mount?
No, the kit includes only the D-Tap to LP-E6 power connector; you need a compatible pro battery with a D-Tap or P-Tap output and any desired mounts separately.

Is the voltage display accurate enough for safe use?
The built-in LED display gives a real-time voltage readout to monitor battery state and helps avoid unexpected shutdowns, though it is not a substitute for a full battery management system.
