The cost of my 2015 Subaru Forester is apparently around 7k. A gas powered generator is 2-3k (and can be refilled with quick trips to the nearest usable gas station) and you can also pair it with a solar-powered one with panels for 3k.
That puts the total setup price to about 10% of a CT-Energy station.
That’s a used car that’s more than halfway through the median lifespan of a vehicle.
We could start comparing used EVs if we want to.
