The iPhone 12/12 Pro Silicone case comes in 8 colors and has embedded magnets that help Apple's MagSafe wireless charger to seamlessly align and snap into place. It costs $49 in the US and €55 in Europe.
The iPhone 12 and 12 Pro Clear Case is a blend of clear polycarbonate and flexible materials and also features MagSafe magnets. The Clear Case for those two again costs $49 and €55.
The new Leather Wallet snaps onto the back of any of the four new iPhones and offers space for an ID and credit cards. It comes in four colors and is made from specially tanned European leather. The stylish Leather Wallet costs $59 or €65.
The new MagSafe wireless charger is the only way to get 15W fast wireless charging. It costs $39 or €45. Of course, you can also use any Qi-compatible charger but that will bring your charging speeds down to 7.5W.
Finally Apple's USB-C 20W wall charger isn't new - it's the charger that comes with the latest 10.5-inch iPad. However with the new quartet coming without a charger, it's probably the one to get if you don't have a USB PD charger at hand. It will maximize your charging speeds and costs the reasonable (by Apple's standards anyway) $19 or €25.
All of the MagSafe accessories, except the USB-C 20W charger, are listed as unavailable as the time of writing, but that should be changing soon.
Next step from Apple: iPhone 13 with usb type-c interface and abolish cable. :)))))
If you'd have read any of my other comments you would know I've owned windows phones, iphones and android phones in the past (currently on an S10), I'm not an apple fanboy. Of course everyone needs a charger, but not everyone need...
