Non-magnetically-aligned wireless chargers are far worse than fast charging.
Wireless charging is a gimmick like 3D TV was. There's only one use case, and it's car use. But it doesn't need to be fast. In every other case it's worse than cable in every aspect
Wireless charging sucks. It costs significantly more energy to charge the same battery to full.
Your phone doesn't have that much energy stored in it. 5 watt hours or so? Now consider the energy cost of making usb-c cords
The charging pad itself probably requires a USB-C cable itself? It takes much more materials to make them than a cable...
It doesn't have plugging and unplugging cycles and doesn't get bent in different directions, so it will basically never break unless you use the phone while holding the charging pad

It's true, but wireless charging is still inefficient and should be avoided.
It's literally a few watt hours. Not kilowatt hours, watt hours. I pay $0.08 per kwh, so after a few years of wireless charging I might pay $1 more
But the USB-C cord might break in less than that time and cost more. Manufacturing cords is never going to be green, but electricity can be made renewable
The charging pad might also break and they require cables themselves, plus all the materials to make the charging pad, plus every phone has to support wireless, which is even more materials. I've never broken a USB-C cable, that's a user issue, you are either being way too aggressive with them, buying low quality ones, or both.
You keep on connecting and reconnecting the USB-C cable, and if you use it while charging you probably bend it.
The cable in the charging pad never gets unplugged
