Please Accept the use of 15v 3Ah chargers

Currently, the PPM speak “PD” to the charger and asks for 15v 4Ah. If the charger says “Sorry I can only supply 3Ah”, the PPM says “forget I asked” and the charger shuts down.

As most PD chargers and powerbanks supply 15v 3Ah (rather than 4Ah), and the 3Ah is more than enough to keep the PPM running full power, could you please make a firmware change so the PPM can accept power sources which can supply “only” 15v 3Ah ?
