Many problems were caused by the discovery that Pixel 3's wireless charging on third party pads was limited to 5W. Although the device with the Pixel Stand was able to fill up to 10 W, other brands of chargers could only deliver so much power if they were included in the Made by Google program. The Pixel 4 avoids this ridiculous limitation and can be charged wirelessly with up to 11 W, even on third-party Qi pads up to 11W. We checked this out at the end and were able to get 8.4W on a third-party Qi charger supporting 9W. Justin Duino of 9to5Google achieved 10.8 W in a separate test .
Left : 8.4 W in our test on a 9 W pad, measured with the Inware app. Correct : Justin Duino's test.
This confirms that the Pixel 4 family has finally lifted this silly restriction on third-party chargers. You no longer need the Pixel Stand or Google approved hardware to charge your phone wirelessly.
