I actually had a USB-PD laptop charger with me on the Meet FP3 event in Düsseldorf, but sadly I didn’t try to charge the FP3 because its battery life is so good that it needed no charger. I still assume it shouldn’t be a problem, though, as long as the phone does not violate the USB-C specification. USB-PD chargers default to 5V if the connected device doesn’t negotiate anything higher.
