Could be colder outside, the battery could be fuller, could be that the charger is malfunctioning, could be any number of other things.

Mine is gas, but still needs power for the igniter and the fan. It is a lot more efficient than constantly keeping a tank of water hot, and it never runs out.

Just in my garage I have a fridge and tankless water heater that would benefit from V2L in a blackout. Within easy extension cord reach I also have my modem, router, and TV. My EVs could easily keep these essentials running for a week or two, and indefinitely if charging is available somewhere nearby.

They’re a Tesla rival in the same way that I’m a Michael Jordan rival because I played in middle school and stunk.

You need an EVSE (commonly confused with a charger) that is compatible with the plug type, regardless of voltage. A level 1 (110) EVSE usually comes with the car, and those sometimes have comparability with level 2 (220) via an interchangeable plug adapter.
