PinePower + PinePhone? - marcih - 01-12-2021
I've recently had the displeasure of trying to find a USB-PD charger, having to wade through numerous "fast charging" USB chargers with no indication of whether it meant USB-PD, Qualcomm QC (never mind which revision), Samsung's Adaptive Fast Charging, or any other one from the myriad of other fast charging protocols. After finally finding one, it (unsurprisingly) still didn't work with the PinePhone, probably due to the incomplete anx7688 driver.
The recent release of the PinePower and improvements of the aforementioned driver renewed my interest, however. Has anybody tried charging their PinePhone with the PinePower? Does PD work (reliably) or does it too charge at 1.5A? Which distro and kernel version were you on?

1.5A is the typical limit that most kernel/distros set.
It is up to yourself to change the values, if you want something different.

There's a very good reason for the 1.5A limit, it's according to the spec. From USB article on Wikipedia:
Quote:USB-PD allows safely negotiating a higher voltage and current. Playing around with kernel voltage limits via sysfs isn't ideal, which is why I asked about people's experiences with the PinePower.
- Battery Charging Specification 1.1 Added support for dedicated chargers, host chargers behavior for devices with dead batteries
- Battery Charging Specification 1.2: with increased current of 1.5 A on charging ports for unconfigured devices, allowing High Speed communication while having a current up to 1.5 A and allowing a maximum current of 5 A
