D-Tap to DMW-BLK22 Coiled Dummy Battery Cable - Regulated 9V Power

In this review the focus is on a practical power accessory for Panasonic LUMIX users: a D-Tap to DMW-BLK22 coiled dummy battery cable that stretches from 20' to 36' and provides a regulated 9V output. The bottom line is simple: this cable is for shooters who need reliable, on-camera power from D-Tap sources without bulky adapters. It stands out for its braided nylon construction and reinforced connectors, and the built-in regulator in the dummy battery keeps voltage stable for compatible LUMIX bodies during long shoots.

Key Features

• Regulated 9V Output: The dummy battery houses a power regulator so the camera receives a stable 9V supply from a higher-voltage D-Tap source.
• Wide Input Range: Supports D-Tap input voltages from 12V to 17V, allowing compatibility with most V-mount and Gold mount batteries and adapters.
• Coiled Length: The cable relaxes to about 20 in for tidy setup and stretches to around 36 in when extra reach is required on rigs or gimbals.
• Durable Build: Nylon braided jacket and reinforced connectors reduce wear and keep the cable serviceable on location.
• Camera Compatibility: Fits Panasonic LUMIX models that use the DMW-BLK22 dummy battery, covering S1RII, S5, S5II, S5IIX, GH5, GH5S, GH6, GH7, G9, and G9II.

Who It's For

This cable is aimed at professional and enthusiast videographers who power cameras from on-board battery systems or V-mount/Gold mount plates with a D-Tap output. It is particularly useful for long-form run-and-gun, studio, or location shoots where swapping camera batteries mid-shoot is impractical and a regulated feed is required.

Those who should look elsewhere include users who need a multi-voltage or higher current solution than 2A, or photographers who only shoot short sessions on standard camera batteries. Also avoid it if your camera model is not listed among the compatible Panasonic LUMIX cameras.

Pros & Cons

Pros

• Provides a regulated 9V feed so the camera receives stable power from D-Tap sources.
• Nylon braided coiled cable minimizes tangles and resists abrasion on set.
• Reinforced connectors improve long-term reliability under repeated use.
• Stretchable design gives flexibility for compact rigs or extended cable runs.

Cons

• Maximum 2A output may limit use with accessories that draw higher current from the camera.

Our Verdict

For LUMIX shooters who need a tidy, durable way to run camera power from D-Tap sources, this coiled D-Tap to DMW-BLK22 cable is a practical choice that balances portability with reliable, regulated 9V output. It is good value for users who require a stable feed and rugged build, though those needing higher current should consider a different solution.

Frequently Asked Questions

Will this work with non-LUMIX cameras?
The dummy battery is designed to fit cameras that accept the DMW-BLK22 shape, so it will only work with listed Panasonic LUMIX models and not with unrelated camera battery compartments.

Can it be used with a V-mount plate?
Yes, any power source with a standard D-Tap output within 12V to 17V will work, including many V-mount and Gold mount battery plates.

Is the 9V output regulated inside the dummy?
Yes, the power regulator is built into the dummy battery so the camera receives a regulated 9V output without extra inline modules.
