The headline at the top of the page is what is misleading. It says it works with Huawei, OnePlus and Xiaomi. What it should say is "only works with Huawei, OnePlus and Xiaomi." There's a big difference. Yes, that information is in the text description much lower in the page, but it should be in the headline.
It means this device does not comply with the USB-C standard, which is why it doesn't work in USB-C compliant phones. UGREEN probably should not use the term USB-C in the headline either, as it doesn't comply with the standard. If you buy other devices in your home, like iPad Pro, or LG, Sony, Google or Nokia phones, this thing won't work.
