Working AC Adapter
#1
Since the PinePhone Braveheart edition does not come with the AC(Wall) adapter I figured maybe we could start up a comparison of results/charge times for consideration.

The only adapters I have are from my current Personal(P30 Lite) and work phone (S9) and previous phone(Essential PH-1)

The S9 Adapter does not specify wattage just says 9.0V == 1.67A or 5.0V == 2.0A

The P30 Lite Adapter does not specify wattage just says 5V == 2A or 9V == 2A

The Essential adapter clearly says 27W 5V == 3A or 9V == 3A not sure I'll use this one since Pine says 15w...

I'll update this post with charge times once i have my device in hand.

I'm no electrician so those numbers mean nothing to me. I also realize that those are note actual = signs but it's the closest thing i could find to represent.

W = V x A

Manufacturers will quote the highest wattage the charger can do, but it may not be capable of the same wattage at all voltages - as an example your Essential charger can do 27W at 9V but only 15W at 5V.

Given all your chargers do both 5v and 9V they're most likely all PD capable, so should work with the PinePhone. The Essential will charge at maximum speed, but the S9 and P30 chargers will be slower.

Good idea, grondinm, I'm in.
I can provide the low-end data points; the two chargers I see around here that are appropriate are in the 1 amp / 5 watt range.

I will post actual specs and charging time when the phone arrives.

Having the "developer" edition ...

CHARGEROBOT MODEL ZST-0650 USB-C charger
INPUT 100-240V 50/60Hz 1.2A
OUTPUT 5V/9V/12V/15V/20V 3A

DOEST NOT WORK - No matter what cable you use, the PinePhone doesn't recognize it.

Okay, it arrived today, hurrah !

Battery seemed to have zero charge, after pulling the tab, phone did not boot.
Plugged into charger (Anker PowerPort Elite 2 (model # A2023)) via a USB volt / amp meter I had laying around, started out at 5.29 volts / 0.11 amp; phone remained inert. About 15 min later I observed that the phone had booted and was now charging at 5.23 volts / 1.49 amps. Current has been tapering off slowly; right now (maybe 1/2 hour later) I see 5.23 volts / 1.17 amps. Another 15 min, 5.25 volt / 0.95 amp.
About 1 hr, 15 min charging, 5.26 / 0.67. Battery got warmer than body temp, but never even close to uncomfortably so, now it is cooling off.
1 hour 40 min, 5.28 / 0.39.
2 hours+, varies between 0.39 and 0.41 amps, this may represent the steady-state load.

Maybe more later, if anything of interest occurs..

The current kernel for the PinePhone doesn't do usb-pd yet, it just uses regular old USB BC 1.2. The max power it will use is 5V 1.5A

Thanks, Martijn !

That exactly matches my observations.
