Can you jump start a car via the cigarette lighter?
I have seen a cigarette lighter plug in devices that claim to jump start cars within five minutes, do they work?

That can only work if the lighter/accessory socket is hardwired directly to the battery. Some are. Some aren't.

I'm thinking of buying a small, portable jump starter to keep in the glovebox just in case I get a flat battery. Is there a specific model or brand that you'd suggest looking at and how much should I pay?
