    Shouldn't have a problem, since the MacBook Air doesn't use that much power. I have a 150W inverter that I use with a Surface, no problem. It uses a similar amount of power to your Air.

    Tesla has a service bulletin for properly tapping into the 12V supply circuit for auxiliary devices.

    Indeed, but it still only gets you a 15A circuit. So if you need more than ~ 150W you'll want to hook up the 12V battery directly.

    Can you plug your charger cable in it? LOL!

    I hooked up a projector to my 12V plug while waiting in the Model 3 line. Not enough amps to keep it from powering down in a few seconds though. :(

    So what is the conclusion , is it ok to wire a 2000 watt pure sine wave inverter straight to the battery without voiding teslas high voltage battery warranty ?

    Mine is not a pure sine inverter, it's a 1000w inverter, I can't remember the brand (and would have to take a wheel off to check) It was something I picked up at Canadian Tire (large all-purpose hardware/housewares/automotive supply chain here)
    I used 4 AWG wire directly to the 12V battery posts with a 100A fuse on the positive terminal, and replaced the switch on the inverter with a relay that's only live when the car is "on" (fed from the fuse box relay that controls the 12v centre console outlet)

    On the downside, the location I mounted it in in the passenger fender isn't quite as weatherproof as I'd like, and it obviously is subject to occasional road spray when the roads are really sloppy out (I get occasional error beeps from that fender, but only in bad weather). I'm going to work on better weatherproofing for it in a few weeks when I'm changing over to my winter wheels and have the wheel off anyway.

    I'm curious as to the real world uses for the inverter. This mod sounds great for a SHTF scenario. What have you guys plugged into the 120V socket?
