SmallRig has introduced USB-C and D-Tap dummy-battery cables for selected Canon, Sony, Nikon and Panasonic cameras, offering continuous external power for extended recording, streaming and interview setups.
SmallRig has expanded its power accessories with a new set of USB-C and D-Tap dummy battery cables aimed at camera users who need longer run times without swapping cells. According to the company’s product information, the range is designed to feed compatible cameras directly from external power sources while maintaining a compact, coiled cable form for field use. The practical appeal is clear: for continuous recording, live streaming or long interview setups, removing battery changes can simplify operation and reduce interruptions.
The USB-C versions are intended for users who want to power a camera from a USB-C power bank or wall adapter. SmallRig says these cables support 9V and 12V USB Power Delivery fast charging, and are available for battery types including Panasonic DMW-BLK22 and Nikon EN-EL15C. The company also says the design includes overvoltage, overheating, overcurrent and short-circuit protection, with fire-resistant PVC and ABS construction. SmallRig’s reseller listings add that the cable is meant to provide continuous power during extended shooting sessions.
For users already working with V-mount or other D-Tap-based rigs, SmallRig is also offering D-Tap to dummy battery cables. The company lists compatibility for Canon LP-E6P, Sony NP-FZ100, Sony NP-FW50 and Nikon EN-EL15C variants, with a 7.8V to 8.4V output and the same coiled cable format. SmallRig says the upgraded chip provides full decoding, which avoids pop-up warnings on supported cameras, and it adds protection against reverse connection, overvoltage and overheating. The company’s own product pages for the NP-FZ100 version and the broader D-Tap range also mention continuous power delivery for Sony FX and a7-series bodies.
One recurring limitation remains the same as with most dummy battery solutions: the camera’s battery compartment door must stay open or partially modified, which may not suit every rig or production environment. Even so, the approach is useful where uninterrupted operation matters more than full weather sealing or quick battery swaps. SmallRig says the cables are now available to buy.
