I just read where Apple will not include the charger in the box, will be sold separately, probably for an extra $100.
I usually don’t need a new charger. I have so many chargers stuck around in different places, I don’t need another. The ones that come with my new iPhone stay in the box. The new iPhones, all of them, can be charged with inductive charging and come with an inductive charging cable. Plug it into any 5V USB source and slap it onto the back of the iPhone. It magnetically adheres and charges the iPhone. Alternately, put the iPhone 12 down on any of many available inductive charging devices (some are as low as $10 on Amazon) and charge away.
