I carry a USB power pack that can also be used to jump a car in the trunk. I’ve used it on several occasions to help random strangers and it’s super quick and easy to hook up to their battery and get them on their way. It’s paid for itself in good karma many times over.

But in this case, the same device could possibly be useful for jumping the 12v battery of the Tesla, enough at least to get the hood open, and possibly enough to boot the computer and select Tow mode. It’s got a decent amperage rating, and it’s specifically designed for a short burst of amps to crank an engine, but it can also do at least 10amp sustained which might be enough drive the screen.

Something like one of these: https://www.amazon.com/dp/B0748D8KT6/

Here’s a video of someone doing exactly this;


An important side-point which this is a good time to remind everyone - the frunk can be opened by applying power to those leads which can be accessed behind the little panel in the front right side of the car. So you should not store valuables in the frunk!


I've owned and used this compressor over the past five years and it's been great. Viair 00088 88P Portable Air Compressor. It does connect directly to the battery but that prevents blowing fuses when trying to use the 12v outlet in most cars.

On battery jumpers I've tried a few but found the GOOLOO 800A Peak 18000mAh SuperSafe Car Jump Starter works very well. I've owned three of them. The first time I had to use it was after it had been sitting in my trunk for six months without a recharge and it worked like a champ. I gave that one to my brother in-law as it was his battery that was dead and we were parting ways after a road trip vacation. I bought a replacement and have used it probably a dozen times, often when I see someone with their hood up in a parking lot and offer them a jump start - works every time.


I bought a set of these a couple of years ago but haven't used them yet. I've found the quality of the portable battery jumpers are very good these days so I've been using them instead.
