High Quality Product, fast shipping

I was very impressed with the quality of the product. The rubber of the cable is the same type used for touring concert equipment. It is made to stand the rigorous road life. The J1172 receptacle, welded box and strain relief demonstrate an attention to detail and provide me with confidence in that my investment will last and keep my car safe. Keep up the good work, I'll be happy to recommend you to any of my EV colleagues.

Excellent quality product!

"After checking out several J1772 extension cords, reading reviews and specifications, I settled on the JLong. The plug is of excellent quality and seems to be better than the one that came on my Panasonic EVSE (modified version of what comes with the Nissa Leaf) or that came with my 2016 Kia Soul EV+. Because there aren't any standard corded J1772 inlets a special inlet holder was built. It is of superior quality with excellent welds and a quality finish. The cord is super flexible which makes it easy to roll up and store in the car. The JLong also comes with two velcro tie straps and a small pad lock. This is definitely a worthy investment."
