I've been living in a rental for a while, and I have a woodshop in the garage. I've been really wanting to have a 220V outlet to run some bigger power tools, but if figured doing that would require hiring an electrician to come do some work in the breaker box. This has me curious if I can do something like this just to power some stuff in my garage, and also potentially charge an electric car.

Hiring an electrician is going to be cheaper probably, depending on the length of the run and how annoying the location is (and if your panel has enough capacity to spare). Unless your landlord is an asshole they probably won't care, in my experience, as long as you get a qualified person to do it. You're basically improving their place so it's not a hard thing to get approved.

Btw for the second part, you _can_ charge electric cars over just normal 15amp circuits you already have. It's just slow, so you'd only want to do it for nightly charging and it may depend on your commuting range if it'll work out or not.

You could get something like an eco flow battery, charge it on your 120v service and then use its inverter to run your intermittent 240v loads. IIRC their models support being in charge and invert mode simultaneously, so you wouldn't have to swap plugs or change settings throughout the day.

The Delta Pro series is capable of running a 3 ton AC condensing unit, so if your tools are less demanding than this it should work out.
