I've been encountering a dead car on a regular basis -- every few days it seems. The weather has been colder than normal (I was in a snowy area) and it seems to happen more often when it's cold. I have purchased a small jump starter from Walmart, but I was recently thinking it would be nice if I could use a jump starter that works through the lighter plug so I can do it without having to open the hood. I have seen small 20000mAh jump starters/usb chargers before that claim to be able to jump start a car, and from what I can see there's no real draw from the jump starter when I connect it to the battery terminals under the hood (since it just turns on the car, doesn't have to start the engine) so I believe one of these smaller units would do the trick. I just wonder if there would be any weird electronic configuration given it's an EV that might be damaged putting the power back into the lighter plug.
While we are on the topic, does anyone have any suggestions on how to resolve this no-start issue? I remember reading about a recall that has something to do with this, and the Ford dealer says the car was treated for that recall, though I wouldn't be surprised if they're wrong.
Thanks a lot
