That said, it's rare that only one or two outlets in a garage are tied to a breaker. Usually they're all on one circuit in older homes, in my experience.

If you can find a circuit like this, though, it's perfectly valid. Many chargers made for 110V also have a 230V/15 or 20 amp mode. My Mother-in-law's portable charger has a 230V NEMA 2-20 adapter that comes in the bag with it.
