MDP-P906 power issue, PD 20V/5A not always

RamPhleg

I'm using the PD3. 1 power source, see the photo. This one works well with TS101 and MHP50 (black Miniware cable, 20V, 5A). However, my new MDP-P906 behaves strangely. Sometimes, it inputs as 20V/5A, but most often as 5V/3A. If I call the menu then the device set 12V/3A. Sometimes, if the current mode 20V/5A, then the device autoshutdown, after that 5V/3A. Also, it doesn't save the setting, max input current as 5A (after restart 3A). I recorded the video. Link https://cloud.mail.ru/public/Xe4R/CwkSPbSJZ

This is most likely a PD protocol compatibility issue. When the P906 connects to certain PD chargers, the voltage increases step-by-step from 5V to 9V to 12V to 20V. If you press the output button when the voltage reaches 5V, it may continue to connect to 5V. You may need to wait until the voltage reaches 20V before pressing the output button again to connect to 20V. We recommend that you use a different power supply with the P906.
