The good news is that after rebooting and giving AirPower commands, they were able to gather a wealth of information about the prototype unit. For example, its firmware version number is June 7, 2017, supplemented by details such as coil settings.
It should be pointed out that the version with 22 coils is shown in the video, and Apple has applied for a design patent for 16 coils (the latter seems to be more likely to be put on the market).
Of course, this isn’t the first time we’ve seen AirPower prototypes. As early as August 2020, another whistleblower had shown a wireless charging pad that was suspected to be scrapped by Apple.

The Cupertino tech giant first announced AirPower in 2017 that can wirelessly charge devices like iPhone/AirPods/Apple Watch.
However, after bouncing back and forth, the company finally axed the hardware product line in March 2019.
The reason Apple gave at the time was that the AirPower couldn’t meet the “high standards” the company had expected, and it was later reported that the company had experienced overheating problems with the product.

Although Apple is quite willing to stack up for AirPower, the densely stacked coils still cause considerable trouble. The company then destroyed most of the test units to prevent leaks, and it was quite rare that they leaked to the outside world.
In 2018-2019, we did not see another prototype of the new AirPower. But the company developed AirPower prototype hardware in 2017 and spent the next two years trying to solve the problem through software or firmware.
Finally, it remains to be seen whether the company will continue to work on AirPower-like wireless charging pads.
