@c_joerg I am also using one of those cheap CA-PS700 replacements with USB connector and an original Canon DR-E17 coupler.
It's working fine but I can't attest that it needs 2.5 – 3A as input. With my M5 it's even working from a USB 3.0 Port of my PC, which delivers 0.9A max. My USB amp meter says the camera is drawing about 0.6A.
