It's about the same as wired AC charging. There are always charging losses:

I don't understand the mention about battery capacity (80 kWh, which would translate to around 7½ hours of charging at 11 kW, if a battery could charge at a uniform rate) or where the "9 kW lost" figure comes from.

*Which is probably useful to melt snow above the device, when installed outdoors on cold climates.

*kWh

Using the right units is important.

They were claiming that they’d gotten the losses down to 2x the wall to battery losses of wired chargers, by removing the transformer in the charger and handling the voltage conversion in the coils.

Also you’re prematurely optimizing. By comparing wireless charging to wired instead wireless to internal combustion. If we did things your way it would reduce the rate of electrification of the market. So calm down.

The way my house is set up I can only get power from the passenger side of my car and almost twenty feet away. There’s no EV I’m interested in that can b charged from that side. They tend to put them on the driver’s side to keep you from driving off while still plugged in. Wireless has no plugin. Which would also simplify public charging stations.

Plus you just got home. You probably want to go inside and may be carrying packages or such, which you might have to juggle or put down to get the cable and plug in.

When it’s time to leave you have to unplug and then store the cable, leave it on the floor (trip hazard for others), or have installed an overhead cable system.

With wireless it’s all gone. Pull into you’re garage? You’re done. You were doing that anyway, so it’s no different. Ready to leave? Just back out. Again, same thing. Nothing extra.

Yeah it’s convenience. But it’s not a small win, it’s big. And it’s every time you use your car. Twice.

Your car can always charge. It can always precondition. You used to have to go to gas stations, now you don’t even have to plug in. It’s fully automatic and taken care of for you.

“You don’t need a remote. You can just get up to change the volume”. How well did that argument go over? Every TV has remotes. Buttons are hidden and effectively dead.

Yet, the five seconds you save by not plugging in a USB cable have led to charging coils being added to nearly every phone to the market these days.

It's a flashy convenience feature, but this is Porsche we're talking about. People interested in buying these cars are all about flashy features without any practical use, because if they wanted a practical car, they wouldn't be buying a Porsche.

Yet I can see the advantages for someone with a disability.

And what a lot don't seem to understand: at 11kW we aren't talking about high charging efficiency anyway. Meaning, you cannot assume close to 100% for cable based charging and talk about how much 90% loose on a full battery (like others here do).
