Rexing - Tesla Extension Charging Cable - 48A 20ft - Black

This extension works, though it could use improvement for safety. Where the wire enters the female connector it is not secured into the shell except by a sleeve that both sides of the shell clamp onto, except the wire still has rotational and in and out movement. This means the wires are secured to the female connector exclusively at the pins of the connector with no internal strain relief. If you used this regularly, pulled or rotated the wire too hard on that end, it may break off at the pins. I improved it by wrapping the wire in electrical tape both where it enters the connector and inside the connector so the wire cannot pull in and out. Solving rotation seems not possible unless the shell is revised to positively clamp the wire internally or if the manufacturer applied an adhesive or epoxy where the wire enters the sleeve. The male end that goes into the car seems to have no issues, though it does not have the button to open the charge port, so you need to use the car or app to open it, and to stop charging and unlock the connector. Most of these cables are like that so no issue from me, I believe the listing says so. The product works, but for how expensive these extensions usually cost (MSRP for this is $300!) I expected the wire to at least be secured to the connector shell properly. If you are handy it can be improved. If you only needed this every now and then it would serve it’s purpose. Just be careful with it.

This works just great! Long enough so that I can charge my second car! No problems at all, the only complaint is that I wish it had a way to unlock the cable manually, you have to either go to the car app and unlock or go to the original cable and click on the button

This a great add on to the existing tesla home chargers. Now i can charge on both sides of the garage and outside as well. No button to open up the charge port is a bummer.

It’s a good length & works fine. Is a bit tight fitting into Tesla charging port at first and should loosen up over time.

Although, to me, it's a little bit pricey, I bought this extension for it's purpose. To extend the wall charger's reach. It works. I read a few "complaints" about this product before buying. Yes, I agree with some of the complaints. One in particular. I have a Tesla M3. It's a hassle to unplug this extender when charging is completed because the uninstall button for the charger is on the wall charger unit. For one person, it's almost unreasonable and frustrating to uninstall it. I usually ask for someone to hit the charger button, while I'm standing ready to remove the extender, at the car charging port. It WOULD be nice to have these "suggestions," looked at. But, overall, it works. Built solid and it's "plug and play."
