Note, this cord is temporarily out of stock, and expected to become available the first week of December. Meanwhile, you might consider our 30 ft version available at this link.
This extension cord is designed specifically for Tesla Model S and other electric vehicles that plug in to NEMA 14-60, 14-50, or 14-30 outlets, commonly found at campgrounds, RV parks, and electric dryer and oven connections. Made with heavy-duty weatherproof 6 AWG cable, it can easily handle 50 amps continuos and is suitable for indoor/outdoor use. Weighs only ten pounds and is compact enough to carry in the car wherever you go. Length, 20 ft.
Due to its universal plug design, this cord will plug in to both NEMA 14-30 and 14-50 outlets. The one end has that universal NEMA 14-30/50/60 plug, and the other end has a NEMA 14-50 receptacle. Handles molded into both ends to make it safe and easy to plug in and unplug.
Note: The plug looks a bit different because it is a special design modified to fit more than one type of outlet. We retain the 240V and ground connections and omit the neutral prong. This makes it possible to safely fit all types of NEMA 14 type outlets. The neutral prong is only used to supply 120V and is not used by electric car chargers. Because of this, it's not suitable for RV use - intended for electric car charging only.
