I think 5mph is pretty typical on a standard 15 amp circuit (pulling 12 amps per code). That would get 40 miles of charge in 8 hours.

And if you hire an electrician to upgrade the outlet to 20 amps you can add another 1-2mph. This can be trivially easy or somewhat complicated, depending on what kind of wire is supplying the outlet. But even in the latter case it's usually less work than installing a Level 2 (240v) charger.
