IMO, some of docking stations presented on this Forum do not deliver more than 5V/0.9A (as we are talking about Librem 5 only here, about 5 volt to be precise, not about PD2.0 in general, not even about PD3.0 with or without PPS, neither about PD3.1 range). It is about pass-through voltage and amperage that Librem 5 is getting from the dedicated USB-C male cable/connector, host related one on any used docking station. AENZR AZ2406 by itself consumes very little power and the shown value of 4.71V/1.37 charging Librem 5 comes from the compliant SoftBank PD2.0 5.00V power supply, therefore way under 5V (and I do not use those that provide 5.20V at all, not even for indirect charging of the Librem 5 as some PD power supplies do provide within nominated 5V specification). Do you want me to post picture with the 20V/3A (60W) PD2.0 power supply entering AENZR AZ2406 (although I do not have Librem 5 with completely empty battery at this moment, need to check, perhaps)? Just because I do not have much time to show everything.
