Modern EVs ship with built-in 120V outlets and Vehicle-to-Load (V2L). The battery is already huge — you just plug in.

The benchmark. Run a job site, power a house during an outage, or host a tailgate from the bed.
Two 120V outlets in the truck bed plus one in the gear tunnel. Ideal for camping and tools.
Two 120V outlets and a 240V outlet in the bed, plus a 120V in the cabin. Powershare can back up a home.
An interior outlet under the rear seat plus an adapter that turns the charge port into a 120V outlet.
Same V2L system as Hyundai. EV9 expands it to multiple outlets and a bigger battery.
Up to ten 120V outlets and a 240V outlet. Targets contractors and overlanders.
Bed outlets plus the option to power-share to another EV.
