Charger for Watch
I go my Apple Watch today. They sent a magnetic USB-C charging cable but no charger. I really don't understand about the different wattages for these chargers but, there is a charger for USB-C cable that is 20W for $19. Is this what I need? Does the higher wattage simply charge faster? Would I be smarter to get the regular Magnetic USB cable since I could charge my watch with my computer or any of my regular USB charger?
