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.
