I'm looking for an extension cord that will fit between the UMC and the charging adapter. I have a NEMA 14-30p dryer outlet and the Tesla 14-30 adapter, but the dryer outlet is pretty far away from the garage. I actually already have http://www.amazon.com/Camco-55195-Extension-PowerGrip-Handle/dp/B0024ECIP0/ref=sr_1_1?ie=UTF8&qid=1449278627&sr=8-1&keywords=14-50+extension+cord, but I don't think this will work with my 14-30 adapter. I know I could buy a 14-30 to 14-50 adapter here (http://www.amazon.com/Conntek-14-30P-Electric-Vehicle-Adapter/dp/B00STD8CXC/ref=sr_1_2?ie=UTF8&qid=1449278695&sr=8-2&keywords=14-30+14-50) - but I was hoping to use my Tesla supplied adapter and not deal with dialing down the amperage. Any leads? Thanks!
