Out of curiosity I hooked the PT2 up to my Anker 65w PD charger and connected it to a killawatt meter. I'm drawing .5 amps at roughly 8 watts. I haven't tested with a 15 watt 3 amp charger yet but that's next on the todo list. Just thought I would drop my findings here.
From what Segfault mentioned in the discord is that it's configured to draw 5V 1.5A with some chargers being able to do 5V 3A.
Did another quick test using a Lenovo tablet charger rated for 10 watts @ 2 amps and I'm drawing .6 amps and 9.9 watts on the killawatt meter.

Since I thought PD was supposed to negotiate the safe limits between the devices.
A couple of possibilities come to mind:
1. The testing just hasn’t been completed to certify that higher voltages are okay
2. The BMS/PD is programmable and Pine has no way to know what OS distributions have done to it.
3. There are inherent limitations in the circuitry that preclude the use of higher wattages.
Basically if someone with knowledge of the charging circuitry weigh in that would be great.
Thanks
