I tried the accubattery app and didn't trust it.
I wound up buying inexpensive usb-c power meters on Amazon.
Start with a phone at a low state of charge.
I've seen up to 25 watts on my Pixel 10 pro xl.
I should have said that Accubattery wasn't giving me enough timely information to troubleshoot the problem.
The problem my Pixel 10 Pro was experiencing is that USB charging started, negotiated, and stopped in a repeated loop with a period of a few seconds, never stabilizing and generally stopping entirely after 5-10 seconds. Accubattery was averaging out the process, so it wasn't giving the full picture of what was happening.
A USB-C power meter clearly showed the USB-PD negotiation starting, the charging voltage steps, charging current ramping up, then quitting entirely, all within 3-10 seconds of plugging in.
My new Pixel 11 Pro charges just fine. So if you have a Pixel 10, it seems the options are:
Charge from the back seat USB port to max out the phone charging rate
Use a USB-C to USB-A adapter with a USB-A to C cable for 10W max charging
Use a Qi2.2 25W charging puck like Google PixelSnap or UGREEN for 25W max charging
Get a Pixel 11. I'm not a fan of black phones in general, but the matte black is actually pretty nice. Mine pulled 19 watts while already at 80% SOC.
Oops, I spoke too soon. I'd previously plugged my Pixel 11 Pro Xl into the console USB while the phone was near 80% SOC and it charged fine. But today when I really needed to charge with the phone at 30% SOC, it only charged for a couple of seconds, then stopped.
I'll submit a bug report to [email protected], and also buy a Google wireless charging puck to leave in the car.
My father-in-law and my sisters brother both have android phones and the charging on the front row USBc ports on a Gravity Grand Touring is to put it mildly "shit". My wife and I both have iPhones and the charging is very quick. Was going to try the USBc ports on the back of the front seats but didn't get the chance.
The ports on the back of the front seats will likely work great for your in-laws, as they did for me, but are inconvenient enough to reach while driving that they are little practical help.

Oops, possible false alarm there with respect to the Pixel 11 Pro - reversing the USB cable at the phone makes charging work or not work every time, with any cable. Reversing the cable at the console end doesn't make any difference, with any cable. I don't know enough about USB-C PD negotiation to understand what this implies.
So this is different from my Pixel 10 pro, which didn't charge no matter how much cable swapping/reversing I did.
