I have no affiliation with Clipper Creek - I just remember them as the provider of the original Tesla Roadster EVSE's and they had the lowest price J1772 EVSE's when I was looking to outfit my garage. I came across a new product of theirs... the HCS-60 which is a J1772 EVSE that can charge at 48A. The introductory price is $899 which makes it cheaper than a HPWC and since it is J1772, more durable than the Tesla UMC for daily use. Obviously it would charge at 40A on a single charger Model S. If this was available, I may very well have chosen to go this route rather than Tesla's HPWC which was the least expensive option for more than 24A charging at the time aside from the UMC. Another advantage is that it has a 25' cord. I have no idea how long this product will stay at the introductory pricing. HCS-60, 48A, 240V Charging, 25?
