Are car jump starters viable?

At CAP3 Sechelt there is an electrical contractor. He has a couple of EVs and has installed a couple fast chargers. So that’s one already. :smile:

None of the places I will fly from will even have that for a verrrrrrry long time. 2 of us flyers at our local strip have EV’s but in no way would expect it – too much of a cost to install.
