This is now a feature of most new Tesla vehicles:

> Powershare allows you to draw power directly from your compatible Tesla vehicle to power your devices, your home or the grid.
> Powershare is currently available for all Cybertruck vehicles, and all new Model 3 and Model Y2 vehicles ordered on October 1, 2026 or later.
> To verify if your vehicle has Powershare, navigate to ‘Software’ > ‘Additional Vehicle Info’ > ‘Powershare Support: Enabled’ on your vehicle touchscreen.
The caveat is that Powershare is low wattage. You really need to pair it with a Powerwall and have an average draw less than the limited capability of the car to supply it.
To power a house directly from an EV, the main options now are the EV trucks -- Lightning, Silverado, Cybertruck all can have this ability, 240V 30A typically
It's not _that_ low, from the Tesla site: https://www.tesla.com/ownersmanual/model3/en_us/GUID-E261502...
> Model 3 provides a maximum draw of 11.5 kW.
You can't run your heating or air conditioning at full tilt, but otherwise that will get you at lot, this is 240V at ~45A.
