>Mediatek Pump Express Introduction
Yep read it. It does even more terrible things (modulating current to change voltage), but no monitoring for voltage drops.
It’s also rarely supported, and looks like they just switched to pd3 (the sane protocol)
- userbinator 1y agobut no monitoring for voltage drops Did you not see: "Do cable imp. Calculation. Protect cable from burnout" on page 12 "Adjust Vbus according to cable impedance/quality" on page 14 and "Cable Impedance Measurement" on page 15? Pump Express is their fast charging protocol, but even before that, in the days of feature phones, they were already doing the measurements and adjusting charging current.
