Could you look at anker 5 port chargers, especially those with PowerIQ and QuickCharge features?
As far as I know at the moment, Power IQ appears to be Anker's trademark for using device identification chips, quite possibly the same CX1901/2901 and equivalents everyone else use.
As for QuickCharge, PassMark sent me one of its USB-PD testers and I was told they MIGHT implement QuickCharge support in the future. Right now, I'm waiting to hear more about how likely that is to happen while I decide how I am going to use the tester in the future, which currently means pestering PassMark with bug reports and feature requests to enhance its versatility.
I did receive three adapters with QC 3.0 support and a plain 5-ports adapter, two from Aukey, two from Anker courtesy from Roger. I could do tear-downs and test them as regular 5V adapters for now, then revisit them once I have something to emulate the protocol with. I could certainly start that batch from the 5-ports non-QC one and pit it against SilverStone's UC01.
At the moment, I have two more cube-style generic adapters in the publication pipeline and I'm partly done putting together a third one about a house-brand unit. (Spoiler: that third one is disappointing for unusual reasons. Though the 'unusual' could simply be because I am breaking into a new form-factor category - at least for me - on that one.)
