Yeah, it'll be easier to stick a bunch of extension cords into the various CT receptacles.People are likely not realizing that this setup (if they dont already have a Tesla Gateway / backup switch from an existing solar + powerwall installation) is going to be a "multi thousand dollar" setup, not counting the car, or the EVSE.
Meaning, even once someone has a cybertruck (or potentially any other tesla vehicle that supports this specific feature), its going to require an installation of hardware, and labor that is likely to be at least 3k more, along with additional permitting.
If you are in power outage prone area though, you might want to go the Powershare route.
