I just moved from charging my Lumia 1020 using a 2.4 amp charger in the car (I think it only maxed at 1.3a), to a Lumia 950. If I use the 2.4 usb-a to usb-c (Lumia 950), will I still get a decently fast charge? Is it better for the battery to simply purchase a usb-c type car charger that supports the full 3a?
