Yeah once I wired it up and tried it would charge for 3 seconds , so quad lock refunded my case(got to keep it) , returned the 12v head and got a normal head with the motorcycle 12v to usb .
Funny thing is my pixel 9 XL wouldn't work with the quaf lock but worked with other wireless chargers. Quad lock support said there investigating it but it's pointing towards the phone
I have a pro and I have noticed that you have to be spot on with the wireless charger for it to connect. Here is a post on pixel forum.
My new 9 Pro XL has odd behavior with wireless charging. I first noticed this with my Anker MagSafe charging puck and a Mous MagSafe Case.
It would show charging for a few seconds, then stop. Temperature of the device was very cool.
First test was to remove the case. This resulted in the same behavior so the case is not the issue.
Next test I tried a regular, non MagSafe Qi charger. I noticed getting the right spot was more difficult than with my Pixel 8, but I could get it to work randomly. But it would seems to randomly start, stop, and get really hot.
Next, I tried the MagSafe pick again by plugging it into the USB-C port of my Macbook Pro. Oddly enough, this works perfectly! With the case on as well, charges as expected with sufficient speed and minimal heat, as I would expect the Anker 20w wall charger to do.
So it seems there is clearly something odd with the amount of power being provided. It seems to be very finicky where the Pixel 8 was not.
