I was super-annoyed this week with the lack of storage in the Model S for one very specific item: the J1772 adapter. I wanted it somewhere in the front seat, so that I could easily grab it. And of course, due to all the minimalism in the cabin, there was no place to put it but the glove box... where it rolled around every time I took a sharp corner. Except that at some point it stopped rolling around. It turns out that in the left rear corner of the glove compartment, there's a tiny space that seems perfectly suited for holding the J1772 adapter. It's not exactly "precisely" contoured to the adapter, but it seems like a very good fit, and the adapter certainly fits in there tight enough to stay put. I can't think of what else this little void would be for.
Is this something you're going to use on a daily basis or multiple times a day? I don't have the 3rd row seats so have that huge area below the floor of the trunk and just keep it there so it's out of the way.
I was wondering what else would go there since it's so deep... I hadn't thought of an umbrella! But I think an umbrella might still fit better sideways. As far as how often I'll use it -- I'll be using it several times a week, depending where I'm parking during the day. And it just seemed silly (to me) to have to open up the liftgate (AND then pile around in the bug area under the floor or the small spot on the left back there) every time I wanted it.
There will be various storage options in the center console area from Tesla and others soon so that should take care of the problem.
Although I have not looked at the "slots" in the glove compartment yet, I suspect that at least one of them is an AC/heat vent.
I just keep the adapter in the bag in the cubby on the left side of the trunk with the mobile charging cable.
Left, rear slot in the glove compartment is a perfect fit. Keeping it in the trunk is a pain, because I don't need to get the UMC out when I'm using the J1772.
Surprise space in the glove box If you haven't noticed on the far left side of the glove box there's space to put a compact umbrella
Warning: It fits great and stays put most of the time, but if you corner crisply it will rock out of that position easily.
Rolls Royce has it right, the adapter should be stashed in the door jamb or on the driver's seat itself. So you can access it standing up, with the charge nozzle in your right hand. If I have to drill a 2.5in dia core-sample out of the upholstery I will! --
