Short and sweet J-1772 to Roadster adapter - lockable

[hcsharp]

I made some more of my short J-1772 adapters. The latest version has a place to insert a small padlock to prevent removal. At 6.5" long it's small enough to leave in your trunk all the time, and especially nice on long trips to free up trunk space. It clamps tight to the Roadster inlet and rated for over 70 amps continuous. All metal parts are stainless steel or aluminum and it's designed for charging in rain and snow. I've made several of these for other Roadster owners and many of them are used daily. I can offer them at a lower price now that I've got a local machine shop helping with production.

The price for the new black anodized version with rounded corners on the J end is $695 including domestic postage. It also includes a free neoprene storage bag! The optional padlock is $4 at any local hardware store.
PM me if you want one.

I ordered one . The small size is a bonus, but the fact that it is lockable is huge. In addition to the adapter cable itself, I carry a cable that allows me to lock it to the car. I always worry during roadtrips that it will be missing when I come back to the car. This design locks, takes less of valuable storage space, and because there is no long cable, it should be less appealing to thieves (no copper cable to walk off with).

I already have the Tesla adapter, but will either sell it or donate it to a Tesla HPC site in the wild.

I'll post a picture after it arrives.

Doh! I just ordered my adapter from Tesla a week ago.

Your design looks very good.

It looks like the lock is on the J1772 side. That means the adapter stays with the charge station's cable, but they can, as always, disconnect it from the Roadster. It also means that if your car is fully charged only other Roadster owner's can share if you're not physically present. Then again, charger sharing can be an iffy thing.

Locking to the car would be superior, but I understand the challenges. Someone here made a ring-like lock unit for the Roadster connection - would that work on this as well? It would work on the Tesla J1772 adapter cable.

I think you're wrong. The lock looks like it stops the barrel from turning and releasing from the Roadster side. This allows the J1772 to be disconnected and shared.

DrComputer is correct. Once you have the outer sleeve twisted onto the Roadster plug, the holes for the padlock line up to insert the lock. Then you can plug or un-plug the J- connector coming from the EVSE while the adapter remains locked to the car.

Return it! Shouldn't be a problem if you haven't used it.

Any issues with the extra lever forces that the adapter will put on the Roadster inlet? If not, this is the product Tesla should have made in the first place.

By the way, has working with the machine shop also allowed you to reduce the price of your 70A plug?
