I tried a Maplin (UK) usb-c charger maplin-45w-usb-c-power-supply-n41ee and while it is a PD capable charger (multiple voltages) Unfortunately it only does fixed voltages and the nearest is 20V... tried it with the Swift3 laptop and it will not charge.
I am having some difficulty finding a usb-c charger that is PD capable that is able to give 19.5V it seems a rather odd value when most other manufacturers have opted for 20v.
Has anyone tried any other chargers that are avalible internationally?
Maplin do a 60W capable charger but again the voltage resolution does not permit 19.5V
My understanding of the PD spec is that the client (laptop) will negotiate with the host (PSU) to recieve the voltage it requires. Now either most PD capable PSU manufacturers have broken this spec by only delivering 5, 9, 12 or 20v or Acer has broken the spec. Maybe thats why they opted not to include it as part of the public specification?
