thanks again for the advice but 1. not in my home and 2. when traveling and I am only able to access a 110 outlet, I take whatever I can get and 3 at my main home I have 220 50 amp service installed so all of this is a moot point for the majority of my charging needs.Check your breaker box and see what breaker that circuit is on. Odds are it's 20A. That's most common in the US, because people run power tools and the like in their garage. No guarantees of course. BTW, if it is only 15A, switching out a breaker is really easy. Your wiring should technically support over 30A (although you wouldn't actually want to put such high loads on it sustained!)
the only reason I commented is because you are offering very broad advice that is not valid in many situations.
