Roughly where in the world do you live that garages don't have power?
You need an electrician to run a new 240v circuit and, in many cases, a new main service for the house to accommodate it.
I only ever charge on 120V personally and have no problem, though anyone who was going to buy an EV planning on charging that way should run the numbers with the EV they’re looking at. ABRP can do a pretty good job of it.
