[FEATURE REQUEST] Also show charger information like voltage/current/power/charging protocol

[KaMyKaSii]

Just as it is already done with the battery information. I currently use a personal script on Termux to see this. It needs bc installed and the logic only works if the charger has enough power to charge the battery and power the phone. charger.txt

Currently acc only outputs the voltage, current, power, and status of the device.
Your requirement is to additionally display the voltage, current, power and protocol of the charger? I don't know much about it, but I think maybe not all device kernels support getting the status of the charger. This may require help from @VR-25, who is the developer of acc.

Indeed, not many devices provide this information. Still, I'm considering the idea. I like your script. I'd like to take a look at your /sys/class/power_supply/usb/uevent as well.

Off-topic: acc wiki is live (and empty!) Anyone is free to add/edit pages.

I thought support was implemented equally as battery information. Using a good USB Tester (TC66C) I see that it reports 15% more power for a standard 5V USB charging and 30% more for a 9V QC3 charging than what is reported by the kernel. I don't know if this difference is due to low kernel precision, loss of energy in heat or both.

Here is the contents of the uevent file:

@KaMyKaSii, try the latest pre-release.

@KaMyKaSii, try the latest pre-release.

Sorry for the late reply. For me using the latest ACC release it is just printing the CHARGE_TYPE, no POWERSUPPLY* info
