you are all kinds of awesome. I am thrilled to have found your page, and subsequently this forum, a few days ago. I glean from other posts that suggested items for testing need be available to aliexpress or banggood. What about ebay? I have a dozen or so wall chargers marked PPS capable I had planned to buy from Amazon but your testing makes my plan of usb meter “testing” silly by contrast.
On your recommendation I will be replacing my J7-c plus-shaped usb tester with YZXstudio ZY1278
