Any 100W PD 3.0 system must support 20V/5A charging. Naively I assumed that therefore they should support 5A at any of the lower voltage rails! But for some unclear reason, I cannot find any PD based system that will output 5A at less than 20V. Here a few examples:

• Anker Prime 100W GaN Charger
• UGREEN 20000mAh Portable Charger
• AmazonBasics Four-Port GaN Wall Charger

This is consistent among all the different brands and form factors I looked at, be they AC adapters, battery banks, or cigarette lighter adapters. What could be the reason for this? If, as a manufacturer, you put in the effort to bulk up and certify your charger to work at 5A, why would you limit that to only 20V?
