Just finished having the HPWC installed. It was a little complicated because the house was built in 1929 and the panel was 100 feet away through underground conduit. Even though we could only use a 50 amp breaker I chose the HPWC anyway for 4 reasons: The cord is 25 feet long, since the unit had to mounted on a wall in front of the car the extra 5 feet should make reaching the charging port a little easier. We only had to run 3 wires instead of 4. I can leave the mobile charger in the car and not worry about forgetting it. It looks cleaner. Now I just need my car to arrive!
