I live in an apartment so I don’t have access to any outdoor plug outlets for plugging in a trickle charger. Nearly every car battery charger requires a plug outlet. I’ve had issues at times in the past with my car battery dying and would like to be better prepared especially as winter approaches in a few months. Not that it’s happened that frequently, but it’s severely annoying when it does happen.
Can anyone recommend one that has its own big battery to supply power from? It would be particularly nice if I could get a good one that trickle charges my battery from the cigarette lighter inside the car, so I could leave it locked in my car charging overnight.
