Bests & Worsts Reviews from Amazon

While the official line is to not use any extension cord with the Tesla UMC/EVSE for charging the Model S, I'm concerned that there will be a time that the 18' cord just won't be long enough. This is a very well made, heavy duty (6 gauge) extension cord, the handles are convenient and it works perfectly well with no warning alerts or anything of that sort when used on the Model S. Can pull a full 40amps continuous without overheating or any warnings. Will be a great backup when traveling. It is very heavy, as you might expect.
