With O-Ring seals on all pins and IP65 waterproofing, it’s built to last.
With a latching feature on the inlet connector, you can be sure your connection won’t be accidentally disconnected.
Ergonomic handles are machined from 100% Ultraform (homopolymer) to very high tolerances and connections are fully encased and sealed internally for protection. Withstands a 5,000-pound collision load from an electric vehicle. Easily fits in the trunk when folded. Built-in mechanism to unlock the EV inlet at the end of charging.
Keep your Tesla charged on the go with this handy extension cord. Compact and durable, it’s perfect for charging up your electric vehicle quickly and easily. Keep it in your car for convenient charging wherever you go.
In addition to using this cable to connect to the Supercharger, there are options for Tesla Destination networks and Tesla High Powered Wall Connectors gen 1, gen 2, and gen 3 appliances. The Tesla Mobile Connector (all TMC / UMC generations) having a proprietary single connector is also quite compatible with the cable. Alternatives for Tesla Destination and home AC chargers are described in the review of different extension cords for Tesla.
How to use?
Make sure to plug the extension cable into the charger connector first and then into the car. The extension cable must be powered first or it will not send a signal to the charger to start charging.
How do I order if the cable is out of stock?
It’s true that the cable is supplied in small batches. If we have an exact date for the next delivery, it will be indicated on this page. Add the page to your bookmarks to monitor.
Is it possible to order a different length?
Since this cable is designed for use with Direct Current Fast Charging, it is limited in length due to security requirements. The manufacturer does not offer any other length at this time.
Is this cable compatible with adapters?
Yes, you can use this Tesla-to-Tesla extension cable with Tesla-to-J1772, J1772-to-Tesla, CCS1-to-Tesla adapters.
Can I use multiple extension cords combined together?
No, it is not safe.
How to protect against theft?
There are different methods, such as using a padlock on the inlet mount with the power cable passing through the shackle of the padlock. We do not recommend a method such as pressing the cable down with a car wheel, as this can damage the cable over time.
Does Tesla allow the use of extension cords?
In the manual for the home charging stations, you may see a warning about using extension cords. That said, Tesla Semi prototype vehicles have been seen using an extension cord on the Supercharger station on multiple occasions.

I was first introduced to the extension cord for the Tesla at the Miami EV expo. The cable was no different from the one shown on the web site and was 6 ft. long. Unlike the longer length cables, they have a notice about the possibility of using the extension cord at Supercharger stations. The plug and socket of the cable locks in well and is similar to the proprietary ones. It looks quite thought-out and safe to use.

If you compare this product to NEMA high voltage extension cables, the Tesla cable is much heavier and less flexible. I will assume that the weight is due to the cross section of the cable for the Supercharger’s power. The connectors are responsive, moderately elastic. The price of course for a piece of wire is excessive. The quality is ok.
