Glad to get a healthy charge at the Lake Charles Supercharger as I exit Louisiana. Interstate 10 West will take me across Houston to the next SC in Columbus but I will need a boost to make it. The Tesla Houston Gallery has a High Power Wall Connection (HPWC) which is not in the same league as an SC but is a much faster than the RV 50 amp.

An HPWC at a commercial business building, such as Tesla’s garage is 205v and 80 amps. A similar power supply at a residential garage is even better with 240v.

Multiply Volts (v) by Amps (a) and you get Watts. Follows are some interesting results for comparison:

205v X 30a = 6kW or18 mph (Level 2)
240v X 40a = 10kW or 28 mph (RV)
205v X 80a = 16kW or 49 mph (HPWC)
240v X 80a = 20kW or 58 mph (HPWC)

MPH in the context of number of miles range added in an hour.

This listing excludes DC Fast Charging or the most common source of power the 115v common household outlet; subjects for a later post.
