Nice, even higher than the 21 kw previously shown on reveal night!
Someone posted these relevant stats on Cybertruck forum, showing how useful and practical wireless charging is even if it's not nearly as fast as plugging in.

Here's some great points I saw posted by Sawyer Merritt
A lot of people in the comments are saying 25kW is too slow, but it’s not. Remember, Tesla’s Cybercab will likely have a battery ~50% smaller than a Model Y’s. 25kW is nearly 2.2x faster than Tesla’s home Wall Connector, which charges at speeds of 11.5kW. A Cybercab doesn't need to charge at 250kW.
If you need to take long trips, Model 3/Y cabs will exist, but the vast majority (about 95%) of all taxi trips are shorter than 10 miles. For the transit-competing taxi trips, about 75% are shorter than 2.6 miles, and the average is about 2.1 miles. The average Uber ride is under 6 miles.
The Cybercab will probably be able to fully charge within 2 hours or so, but even 30-60 mins of charging will be enough at times. It's also likely that the majority of Cybercabs will be part of Tesla’s own fleet, rather than owned by individual consumers, so faster speeds won’t be necessary if the fleet is big enough.
Because the Cybercab doesn’t have a physical charging port, this lowers cost and makes it easier to manufacture.

For anyone wondering about the efficiency of wireless charging vs. wired, this should put you at ease --
https://witricity.com/media/blog/a-beginners-guide-to-wireless-charging-or-is-it-really-that-easy#:~:text=In one word, yes.,(and is most efficient).
In one word, yes. When it comes to wired vs. wireless EV charging efficiency, wireless charging is just as efficient as a Level 2 plug-in charger. In fact, it's likely you're operating in the 20-80% state of charge (SOC) range that your battery likes (and is most efficient).
With plug-in charging, it’s less likely that the 20-80% SOC range will be maintained since many drivers tend to forget to plug in. Some drivers even charge only once a week or drive all week and then plug in on the weekend. Not only is this less efficient, but it’s harder on the battery. With wireless charging, simply park and charge.
