Battery will die then what
Battery will die then what. You die. Don’t leave it plugged into car charger. When new cars are off they kill the portable batteries. Live and let learn or die and let learn. Probably same goes if you plug in ac out let and unplug the wall but leave it plugged into battery. So it sucks watching someone gasp for the needed air for 399. Unhappy customer here and ask for credit card info to help but say it will be refunded. Nope pass
