If you’re tired of trying to run things one battery at a time, but you aren’t quite ready for rails and a v-mount battery, this is your key to running off vastly cheaper USB-C power banks. Will you be able to make any given power bank work with it? That depends 100% on your setup. The details on power are in your manual, do the math and if your power bank can supply the correct wattage, you’re golden. (Your camera will think it’s plugged into AC, so don’t expect it to register the power bank’s charge.) OEM batteries are compact and fine out of the box, but particularly if you’re doing high bitrate video, you’re going to need more power than said batteries can supply. This gets it to you without going full-on v-mount.

It worked flawlessly in a Canon R6 MK II attached in a powerbank as well as in a standard charger. Great value for money! I didn't notice any restriction compared with standard batteries. It substitutes with good compatibility.

This is NOT COMPATIBLE with the Canon 60D model. The camera does not power on.

Works fine with my Canon EOS R5. The cable is shorter than I expected. The image on the product page shows a 30cm straight section, an 80cm (when extended) coiled section and a 25cm straight section. It's actually 80cm (about 30") total length cable that is coiled in the center and it takes a fairly significant amount of force to stretch it. The force is enough to unplug the USB-C connector if its stretched to more than about 24" in length. You will probably need an extension cable. Make sure you have a charger/adapter that outputs 9V or 12V over USB-C.

It’s perfecy

I have been using something similar, which uses DTAP, then converts it to USB-C at the right voltage. This skips a step, so I can use just about any power bank with PD.

I have an EOS R6 ii, and this dummy works fine inside the camera. It does *not* work inside the battery grip though (confirmed by seller whom I asked - no reason provided), which is too bad as I will have to first uninstall the grip every time I want to use this dummy. I will keep it as it can still help in certain situations, wasn't overly expensive, and I don't like product return hassle - but I would not have bought it had I known that it won't work with the grip, which I use practically all the time.

If you film video or stream with a Canon DSLR or mirrorless camera, this dummy battery is a smart investment. It delivers consistent power through a USB-C connection, making it easy to keep your camera running for long sessions without relying on hot-swapping batteries. It works flawlessly with the Canon EOS R series and other compatible models, as long as you’re using a stable USB power source. I tested it with a USB-C power bank and a wall adapter, and it held up during multi-hour recording sessions without overheating or cutting out. One thing to note: this isn’t a battery charger, and it won’t power the camera from just any USB source; you need one with sufficient wattage (ideally 9V/2A or higher). A quick read of your gear’s power draw is helpful before using this in the field. For content creators and live streamers, this is a practical and well-made tool worth keeping in your kit.
