I googled a bunch of sellers on Amazon to get more info about products before buying a home charging cable extender for my Ford Lightning truck. I have to park outside and my outlet is in my garage, so I needed an extender cable that was legit. This company has their own website but sells through Amazon. The products are manufactured in the USA and they’re UL certified, unlike a lot of other products on the market. The cable is thick and sturdy, the connectors on both ends are secure and well made. I have been running the cable under my garage door to my driveway to charge my vehicle for about a month and it’s been much better than a standard extension cable, no noticeable heat from the cord or any other issues with charging. It has been raining a lot and the connection is clearly water-tight. I will absolutely buy more products from this manufacturer in the future, and I hope they create additional products (such as charging adapters) in the future.

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.

Size: 20 ft- 48 amp
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.

We needed an extension cable for your Juice box cable for our Tesla. Bought this, works great, easy to hookup. No problems with charging. High recommended

The charger worked well for several months, then I noticed the cable and adapter were separating after 12 months of use. I attempted to contact Interset several times via their website email support system, and received no response. I’ll try to find a support phone number to speak to them directly, otherwise I’m very disappointed in their lack of service and 2 year warranty support.

Could have been great. Works exactly as described and 40 amp charging is consistent and reliable. However the casing and wires are prone to twisting. I have a home charging unit and the wires and casing are thick enough and sturdy enough not to twist up. You can easily wrap up the cable. This extension is harder to coil up as it twists up and you have to take more time to wrap it up. Otherwise it's a good deal and works well.

Used this 21ft, 40A cable to extend our Rivian home charger cable outside of our garage while the garage concrete was being re-poured. Kept the same charging rate (18mi/hr @ 40A) as the charger alone. Comes with a nice carrying case as well and build quality seems very good. I’m very happy with the purchase.
