@matildalove@wetdry.world @valpackett@social.treehouse.systems however, this causes a problem: if a device manufacturer *assumes* that the source is one of these noncompliant ones that just lets you draw 1.5A no matter what, then they can save a few fractions of a penny per unit by not including the resistors!
unfortunately when you plug the device into a USB PD compliant source it *does* check for the (missing) resistors and won't give any power.

@matildalove@wetdry.world @valpackett@social.treehouse.systems these adapters monkeypatch the 5.1kΩ resistors back in, so that the device now works properly with proper USB PD compliant sources.

@gsuberland@chaos.social @matildalove@wetdry.world @valpackett@social.treehouse.systems Would it even give you 500 mA? I always thought you get no voltage at all, and that seems to track with how my PD chargers from UGREEN and Pine64 behave
