This statement isn't quite accurate. First, there's no such unit as "KW/h." That has to be a typo. It's like saying "horsepower per minute." KWh doesn't work, either. The unit you're looking for is kW -- kilowatts. Second, it all depends on what kind of "wall socket" it is. Behind my range on the wall is a receptacle that will deliver 9.6kW (at the NEC required 80% demand factor) for as long as you wish. Allowing for 90% charging efficiency, that would charge a Tesla 50kWh battery to 80% SOC in 5 hours and 48 minutes. Third, you're a little low even for a regular 20 amp branch-circuit receptacle. As long as it's a 20 amp rated receptacle, it can deliver up to 80% of the circuit's rated capacity -- 1.92kW -- for an indefinite period. Even a 15 amp receptacle can give you up to 1.44kW continuously.
