My wife need to be at Hotel that has a the standard NEMA 5-20 (with a 20 Amp breaker because its a commercial setting) in the garage. How much charge can be drawn on it using the Tesla mobile connector? I tried to search but could not find any chart for that. At 80% draw that should be around 16 Amp. How many miles per hour would that add to the Model Y? This will help figure out how many times she needs to hit the Supercharger that is far off. Thanks
