Eventually, I’m going to pick up a longer charger for my iPad Pro 11”, but that’s easy, I’ll just get the 2m one from the Apple store. My question is, I would like to have a car charger for it as well...I might have an old usb to usb c charger laying around from my s8 plus I had...would it be safe to use it? I’d like to not have to buy a new car charger brick just to accommodate the usb c cord if I don’t have too.
