I use my Canon EOS R8 quite a bit and my photo/video usage is split about 50/50 with a slight lean towards video. While I find the LP-E17 are adequate for photography, for video they are less than adequate. That’s where this dummy batter power adaptor comes in handy. I paired this with an Anker powercore battery/charger supply and I can now shoot 4K video for hours remotely! This has become an essential part of my camera kit and if I lost it, I’d buy another. Highly recommended!

Doesn’t work on R8. Cable power light came on, but camera wouldn’t power up.

A brilliant device if you're using a tripod. Great to not worry about my battery dieing when I'm filming.

This is an excellent product that allowed my R8 to record the entire 2 hour limit while connected to a PD power bank.Only 4 stars due to slow shipping for a product from Amazon.

Works perfectly with my Canon R8.

I would not recommend this dummy battery. It broke my camera and had to send it to Canon for a repair, I was getting error 70 with different power banks when i was trying to take photos and at the end the camera die. DO NOT BUY.

Very good

What can I say? It works. No more faffing with batteries every hour on set. Just be aware that a PD power bank can only be used for the camera at one time. Second you plug another device in camera shuts off. Pick up a tiny extra bank if you need a supplemental cooling fan or something
