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.

It’s perfecy

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.

This thing does not deliver enough voltage to power the camera as a WebCamera. When i change to battery the camera works perfectly, perfect frame rate. With this dummy battery i get very little frame rate. I have tried many different power bricks and still no change. I am out of my return policy window to return it. This thing is trash now.

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.

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.

This dummy battery is working great so far. I really like that I can set my camera up for extended shutter shots and not worry about the battery depleting. I am using this with a hefty power bank and I am able to shoot the sky at night for much longer than I could with the single camera battery. Very happy with this and the price is really great for what it provides.

Could not get to work with a Canon R5 II. It did work with a R7 so it's better than the other one I tried. I have used this brands batteries in the past so I had high hopes for it. It supplies power to the R7 indefinitely so it's good for long sessions like astrophotography. I suspect that maybe these types of power supplies are not going to be supported by camera manufacturers in the future due to the higher power requirements of modern mirrorless cameras.
