A.N. –
I purchased the 48 amp extension. It is made of #8 (or 8 AWG) wire. This is the same size as the cable used on a 48A Clipper Creek charger. A 40A Clipper Creek charger uses #10 (or 10 AWG), which lines up with the 40A extension sold by Inteset. I’ve only used the cable once at 24A so far, but it worked flawlessly. The terminations look professional, and the bag is a nice touch. The cable itself is heavy but flexible and has no memory issues (it does not curl up on its own when stretched out). It came with a label zip tied to the cable that indicates the maximum size charger to use. I plan on leaving that attached as a reminder.As an emergency extender this cable seems to be the best choice. I purchased a 50A extension cord that would go between the charger and socket, but realized that only works with a 14-50 receptacle. This 48A extension will work with whatever charger is available and at L2 or L1 charge rates. I purchased the 48A version as that is the highest charge rate my Mustang Mach E will accept. So I can use this extension with higher rated chargers as the car will limit the current to 48A, which happens to be the rating of this cable.I want to include some information on the NEC (NFPA 70) and the rating of this cable. These reviews had me really concerned as I do not want to burn down my house! However, people are attempting to apply building code to the size of this cable. That is not appropriate. For anyone interested please refer to NEC, 2023 revision, section 625.17(B), pg 559: the NEC does not specify the size of the cable between the charger (EVSE) and the vehicle, they leave that to UL. There are NEC specifications (625.17(A)(2) pg 559) for the cable between the charger and the receptacle (or electrical box that connects to the building wiring) but that references the ‘flexible cord’ tables 400.4, 400.5(A)(1), and 400.5(A)(2) on pages 287 and 288. Those tables do NOT use the 80% rule; probably because these cables are not to be placed inside walls, use different insulation, etc. As these tables should not be applied to this extension I included what size of cable 40A and 48A chargers use which is #10 and #8 respectively and is the same size as the cables offered by Inteset. This would be a safe check when using the extension… if the charger cable is smaller or the same size as the extension (per label on the side of the cable, not the diameter of the cable) then you’re good to go! Also, wire size is backwards: #8 is bigger than #10, which is bigger than #12, etc.

Perfecto como extensión
Just a reviewer –
I bought it when I bought my car 3 years ago. I never had any problem with it. I keep it in our trunk now, and I used it every day for our first year. I never even think about it because it just works as expected. I read somewhere you’re supposed to plug the charger into the outlet first, and THEN plug it into the car. Tbh not sure why, but I usually try to do that. I’ve used this thing in the rain without any problems. Seems to be good quality and I’m happy with it.

I bought a different extension cord at first. Slightly cheaper, but it didn’t have ANY markings on it and seemed to generic for my comfort level when running 220 power. This one, however is stamped properly and appears very heavy duty. Love it so far and it’s charging beautifully while getting us out to the driveway.

I was a little skeptical of this cable based on the mixed reviews and online searching generally being against J1772 extensions, but the cable has been working for my needs so far, which is occasional use when I can’t get close enough to my charger.Generally I can park within reach of my Wallbox and avoid using this. But in spring/winter when I have other things parked on the driveway and I can’t get close enough, I will pull this cable out. It has never given any troubles with the car or charger, doesn’t get hot to the touch, and feels solidly built. So full marks.One caveat is that I haven’t used it at 40A. My Wallbox is normally set for 40A, but based on the other reviews, when I’m using this cable I lower it to 32A output. If your charger doesn’t support easily adjustable output amperage, you may want to go for the 48A cable.

After getting a second EV I needed to be able to reach the rear of my garage for charging. Unfortunately I had positioned my charger where it was convenient to reach the first car but not the back. This product completely solves that problem. Have used it numerous times since purchase and not encountered any of the reported issues from other reviews (fraying of plastic cover at junction to connectors, damage to connector port). Works perfectly with Tesla adapter and running 32A charger. This product is a little more expensive than some others advertised on Amazon but since it is made in the USA I figured there is probably better product QA/QC than other cheaper products. A little more important since you’re working with something that’s hooking up to your car and electrical system.Would definitely purchase again if necessary.

Has worked great since I purchased it a year ago. Only minor issue is that the part that attaches the hose with the connector to the car slides and exposes the (covered) wires, so I reinserted it and now grab the handle lower (including that part) when holding, connecting and disconnecting it to the car and it has not been an issue. Use it to charge a Tesla Y in a 2 car garage.

The cable is not a great quality, and not very flexible. The J1772 connector is built /formed well, and it doesn’t fit well into any of my car’s ports. It gets stuck going in and getting taken out. I cannot recommend it.

I have a few of these in use at various places I charge and bought this one to try as the one I usually have was out of stock.Unfortunately, the cable cover is coming off the handle and it seems to be warmer than usual when charging. I am concerned that the wiring inside is loose or worn causing higher resistance to occur.My other cables I’ve had for over 4 and 2 years with no issue. Hoping this can be repaired.
