plugged in a 110 to recharge.

It is for use with an oxalic vaporizer. Is there something like a car jump starter? I wouldn't mind spending a little more if it can also be an automobile battery charger. I wondered about a centech 3, but I don't see the terminals to connect my vaporizer and there were a number of bad ratings. Right now I remove the batteries from one of my cars, but it is a pain. I don't want to buy a battery and a charger, but I know nothing about power chargers or jump starters. Below is a photo of a vaporizer. I connect the clips to a car battery and use it for about an hour at a time, several times a year. But it would be nice to have a backup auto charger if there is a combo unit. TIA for suggestions.
