The outside plug is seldom on its own circuit in a condo, and you can't pick up much power there. Usually it is GFI protected from a circuit in your condo, most likely a bathroom, or possibly 2 bathrooms. To do what Tony is talking about, you would lose power to these other plugs, and as he said you still don't get much power. To get the kind of power most of use use to charge our Teslas, you need a new circuit from your main panel. It's usually difficult to run a new circuit to the outside in a condo. You need an electrician to look at it and see how difficult it would be to run a new 240v circuit, and if your panel could even accommodate it. If you can't run a new circuit then you need to turn off the breaker to that outside plug and see what you would be giving up inside to convert it, and whether it would be worth the cost and the loss of plugs, for what power you would get. Depending on how old the condos are you would need to check all the plugs to find out what you would loose, because very old condos might not even be wired thru the bathrooms, but thru another circuit. Good luck.
