I took this extension cord on a nearly 6,000 mile road trip in my 2015 Tesla Model S 85D and this extension cord enabled me to easily reach 240 volt outlets at the 4 friends/families homes we stayed at to charge our car overnight. I used NEMA 10-30 and 14-30 adapters on the end to be able charge from dryer outlets, and just used the extension cord as is to charge from NEMA 14-50 outlets. It is heavy and bulky, but it fits easily into the frunk and we could fit many other things still in the frunk with it. Totally worth buying and having to greatly expand the charging possibilities. This 30 foot cord along with the gen 1 mobile connector the Tesla came with which is 20 feet long means we can reach outlets up to 50 feet away! We've never needed that, but we have parked out in the driveway of the home before and this cord enables us to reach through the garage and into the laundry room of the home. The biggest inconvenience is that the cord is real thick and it forces any doorways to remain open by an inch while charging but that's not the cord's fault. As far as extension cords go this cord is quite expensive, but considering how heavy duty it is I think the price is worth it. I was never able to charge at the full 40 amps this cord is capable of due to the circuits I was plugging into all being 30 amps. Charging at 24 amps overnight and this cord was still cold, but that's not saying much.

Great Cord and Great Price

Size: 30-Foot, Style: Standard End

I got an email from Camping World telling me about a sale on these extension cords. I looked at their site and they wanted about $140. I really needed the cord and almost ordered from them, but I checked Amazon first. Surprise: It was lots cheaper here. Yay. Deal done. This is a great cord. My stock 50A power cord that came with my fifth wheel is too short to reach to my house and plug in and charge my coach batteries. I've used other extension cords, but they sometimes get hot--especially if I don't completely uncoil them. So now I use this Camco extension to reach the outlet in my garage. Even though the garage outlet is only a 20A breaker, it's still a more efficient charge and safer connection to use the stock cord, plus this extension, plus the dog-bone adapter to reduce down to the 110 outlet. The connections are clean and I get the best charge I can possibly get from that outlet. As long as I don't run the air conditioner or any other heavy appliances, I won't trip the breaker in the house panel. This cord is constructed well. The ends are good and easy to plug/unplug. The Velcro carrying handle is a big help too. Well done.

Honestly. Hope for the best, will update...

Size: 15-Foot, Style: Standard End

Durable solid high quality built. Got a 15 ft and the length is perfect. It's so heavy, can't imaging if I have got a 25ft or 50ft one. I bought it because of its using 6 gauge wires, and 8 gauge for the ground. I am using it on a 40a circuit breaker and running on a 8 gauge wire from the breaker to the NEMA outlet, so limited it to charging the EV with 32a max. Not expecting it to be heating up the wires or burning the heads, will update this posting if it does. May 20, 2025 update: solid build cord, very durable. It does a perfect job what I have expected. The head feels just slightly warm with my setup. Glad that I bought this.
