What is the suggested extension cable for this? This cable is too short. I need extension cable for this to connect to adapter connected to power outlet.
Very long USB cables tend to lose power, so to extend the reach of the Tether Tools ONsite Relay C Camera Power System, I recommend plugging the USB-C to AC adapter that you are using into a regular wall outlet extension cable, for example, this Watson AC Power Extension Cord (16 AWG, Black, 25'), BH # WAACE1625BU.

Do I need to buy a Coupler to connect my EOS R5 to the AC wall power? Or just can do it throughout the USB-C included?
No, the Tether Tools ONsite Relay C Camera Power System only work with a coupler.
This is the coupler for the R5, https://bhpho.to/3GNG1xc .
