Hope this isn’t a dumb question- but does anyone know of a portable battery charger/maintainer that’s can be used to keep a battery at 12v while I’m working on the car? I have to store it in garage with no power available. I’ve used a charger in a friends garage that you can hook up and it will keep it at 12 while you work on it but it has to be plugged in to the wall. I’ve seen all the portable jumpers but don’t know if I just leave it attached if it will do what I’m looking for, or if those are only to start it and you have to disconnect right away. Don’t want to damage anything. Thanks for any help
