I appreciate your math, but you’re not addressing what I said. I’m talking about weight of the devices, not the power loss/inefficiency of wireless charging. Wireless chargers require relatively a lot of wire in coils, and that adds weight. Additional weight costs fuel all the time, regardless of whether people are using it.

Given that some planes already have inverters to provide power for many types of devices, including phones, it does not make sense, from a weight perspective, to add another type of charging that can only be used by phones. It would be redundant. The power loss from wireless charging itself is just an aside.
