Tesla J1772 mobile connector standardizes Roadster, costs $750 the industry standard J1772, adopted by automakers and energy firms over a full year after the Roadster's debut Tesla Roadster, that's just another drop in the ($100,000) bucket.

That non-standard charge port on your Tesla Roadster isn't proprietary, it's just outmoded -- but don't worry, a four foot adapter is here to save the day. This new J1772 to Roadster connector bridges the Roadster's 2008 designed charge port to the industry standard J1772, adopted by automakers and energy firms over a full year after the Roadster's debut. The new coupling cable will juice up your wheels in just four hours at EV stations outputting 70 amps, or in seven and a half hours for the average 32 amp level 2 charger. Native plug access to those thousands of ChargePoint stations will set you back $750, but if you've already bought a Tesla Roadster, that's just another drop in the ($100,000) bucket.
