Every EV can just hook up with a (mostly) passive adapter to any outlet and get a charge. It won't be fast (especially if you are cursed with a 110V outlet), but even in the boonies an overnight trickle charge will get you to the nearest fast charger. Just get the relevant adapters for your car.
This is basically what your generator would do except you want to lug it around instead of leveraging the cables that we pulled within driving distance of everywhere but the most remote trails? The whole point of electricity is its versatility and ubiquity!
FYI using a wall plug to charge an EV is a perfectly normal thing to do. For a small(ish) commute, regular 220V@10A is way more than enough to get back to full overnight. It won't give you 500 km of range, but only freaks and truckers drive 500 km every day.
