I have a few Canon cameras that all use the CA-570 power adapter for wall power. I'm also running USB-power to all of the cameras to power various accessories like tally lights, signal converts and whatnot. Has anyone managed to dig up a USB (preferably type C with PD) to 8.4V 1,5A coupler with the same plug as the CA-570? I know there are dummy battery types that do this but I'd much rather have an adapter that uses the DC plug already on the camera. My cameras use different types of batteries and I like to keep a battery in the camera as a backup.
