On a related question - has anyone experience with/views on this type of 12v jack/inflator?
https://www.kogan.com/nz/buy/certa-3-1-tyre-repair-tool-kit-electric-jack-wrench/
While I have no need for the wrench (which only adds to the weight - 9kg for the set), I will need both a tyre inflator and jack, given my new car will have neither.
Also, how worried should I be about the car’s ability to supply the necessary power (or what this will do to the battery)? I see this unit can connect directly to the battery or 12v accessory fitting, with some figures I’ve read for my car saying the latter can provide a 12A continuous draw with a 16A peak (the specs for the Kogan say 13A max). I think, however, that relates to the previously used lead acid 12v, whereas I understand Tesla has moved to using a lithium 12v - is that a reason to tread more carefully and avoid 12v-powered items like compressors and jacks? (So therefore stick with a battery-powered or human-powered (ie bike pump!) inflator or and a conventional jack?)
So no experience with, or even opinions on, this type of jack (or the impact on the battery)? Opinions are one thing that's not usually difficult to get on GZ!

just had a quick look at it. never used one.
thing to note that the jack only lifts 30cm. that may be not enough unless you jack on the suspension. otherwise i actually like the idea, more compact bottle jack. tho personally a manual one would be better.
amp draw is pretty small for compressors. most car ones are simplistic junk. i go by the rule of get the biggest one you can carry in the car. drawing 30-40 amps is nothing to a battery.
a 12v hammer drill/wrench would actually be quite useful. but a simple wrench is a lot smaller.

Thanks for all the comments (and opinions!); I'm still kinda keen on this (if it's suitable) as it kills two birds with one stone.
In regards to stability: as I'm no off-roader, I imagine the most likely non-flat area I'd be needing to lift the car would be the side of a rural road, so I get that could be a potential issue. Would carrying a (relatively small) flat sheet of ply or similar to put under it potentially help with stability?
As for height, yeah it's hard to know if this would provide enough without actually testing it; it's not helped by the specs in the manual, which actually provides two sets of measurements (whatever is an 'update item'? New version of the product?):
I've read reports of ground clearance for the Model Y of 167mm, so I'd have hoped that would have been adequate, even on the 'common item' measurement?

Looks like the minimum number would be the device height, when the jack column is collapsed. Maximum when it's extended.
