I have a question as I ran into this few months ago.My model 3 just die out few miles before the supercharger.I got it towed to supercharger after a long delay and it was only two miles away.Is there a portable charger available with enough volts and amp to charge any Tesla car to give it enough power to drive few miles to the supercharger.I am not talking about charge for long drive but just few miles.

Sometimes you have to stop at a free slow charger for 20 minutes. Chargepoint is the most common one. Plugshare shows Tesla destination chargers that are a little faster as well as several others.

Nothing you could just carry around yourself, no.
Some tow companies and roadside assistance services are starting to equip trucks with the ability to do this.
Zipcharge Go is supposed to begin shipping 'soon'. Its basically a (large) suitcase filled with batteries. Seems like a really mediocre thing, TBH. I can't really see the market for it, considering it takes up much of ones trunk space, costs a ton of dough, and unless you aren't paying attention you should really never need it.

Zipcharge looks interesting
So, I found this proposed device today - supposed to be coming in 2022: https://www.zipcharge.global Since I live in an apartment, it seems like a worthwhile thing to have. I have signed up for further information, and if you also fall into the demographic (EV owner without charging ability at...

Yes there is!
YouTuber Tesla Bjørn has been uploading videos of what happens to different EV's when they reach a low state of charge enough that they can no longer move on their own.
He carries out this test on a side road near a DC fast charger which has nearly no traffic at all, but the important thing is he brings the EV's back to life, just enough to move a few miles to the DC fast charger, using an EcoFlow DELTA Max with a 4 kWh setup. (You can have a 2, 4, or 6 kWh setup with the DELTA Max model).
He has found quite interesting results doing this experiment, as the BMS deals with the very low SOC very differently in each EV.
For example the fat Audi e-tron wouldn't move after receiving nearly 3.6 kWh (after losses) from the EcoFlow. He is also able to see how much lower hidden buffer the battery has (after the vehicle claims 0%) and what user alerts the car shows the driver before killing the powertrain due to lack of power and protection to the high voltage battery.
Anyway, I highly recommend watching those videos and I've even bought an EcoFlow myself, which I bring with me every road trip I take, (it's very heavy as you might imagine), but fortunately I haven't been able to use it... yet.

Thanks Art,
Yes exactly that was my question and you answered it perfectly.I did look at those videos and ecoflo is costly.I think it will take few years before cheaper versions will be available.I feel all EV owners should have the opportunity to carry something like this for emergencies.

Some areas may never have the charger population necessary to be practical. For drivers that regularly have a charger shortage an auxiliary will make sense. Otherwise the extra weight will be reducing range nearly everyday. And if not maintained properly would fail when needed.
