Dummy Batteries, AC Adapters and DC Couplers

A dummy battery (or DC coupler) is a hollow adapter shaped identically to your camera’s standard lithium-ion battery that connects your camera directly to an external, continuous power source:

• Uninterrupted Power: Eliminates battery swaps, allowing your camera to run indefinitely during long studio shoots, multi-hour livestreams, podcasts, and overnight timelapse photography.
• Prevents Power Loss Interruptions: Eliminates the risk of a camera shutting down mid-take, corrupted video files, or missed frames due to a drained battery.
• Reduces Internal Camera Heat: Since lithium-ion batteries heat up significantly during heavy video recording and charging, using a dummy battery keeps the battery compartment cool and reduces heat-induced camera throttling.

Dummy batteries connect to power sources using three primary interface types:

• AC Wall Power Supply Kits: Plug directly into standard wall sockets via a DC transformer (such as KingMa DR-series kits), ideal for fixed studio setups, streaming desks, and indoor video production.
• USB-C Power Delivery (PD) Cables: Draw regulated power from portable USB-C power banks or high-wattage wall chargers, providing portable continuous power for field recording and outdoor timelapses.
• D-Tap / V-Mount Rig Connections: Connect directly to heavy-duty V-Mount or Gold-Mount cinema batteries via D-Tap ports, powering your mirrorless camera and rig accessories off a single central battery source.

Dummy batteries are strictly camera-model specific and must match your camera's native battery compartment dimensions and voltage requirements:

• Sony Mounts: Match NP-FZ100 (for full-frame Sony A7 IV, A7S III, FX3, A6700) or NP-FW50 (for earlier Sony A6000-series and older A7 models).
• Canon Mounts: Match LP-E6 / LP-E6NH / LP-E6P (for Canon EOS R5, R6, 5D series) or LP-E17 / LP-E12 (for Canon R10, R50, M-series).
• Nikon, Fuji & Panasonic Mounts: Options available for Nikon EN-EL15 series, Fujifilm NP-W235 and NP-W126, and Panasonic DMW-BLC12.
• Cable Pass-Through: Always route the dummy battery cable through your camera's rubber door grommet/pass-through port so the battery door closes completely, as most cameras will not turn on with an open battery door.

High-quality dummy batteries from trusted brands incorporate built-in voltage regulation and electronic safeguards:

• Step-Down Voltage Regulation: Converts higher input voltages from D-Tap sources (12V–16.8V) or USB-C PD profiles (9V/12V) down to the exact 7.2V–8.4V operating voltage required by camera mainboards.
• Integrated Safety Circuits: Protection against over-voltage, over-current, short circuits, and reverse polarity shields camera logic boards against electrical surges.
• Stable Power Delivery: Prevents sudden voltage drop-offs that can cause camera error messages or emergency sensor shutoffs.
