Looks quite great, thanks! However, the size and price is a bit overkill. For such multiport usage, the MagicFox PD180 京东(JD.COM)-正品低价、品质保障、配送及时、轻松购物! is cheaper and has higher wattage.
YZXstudio has a newer model ZC918P that does 160W. I bought one off ebay, but it’s also available aliexpress. Like other YZXstudio products, it’s good quality but quite expensive.
The Magic Fox PD180 looks very interesting. I think it is unique in offering PD input. Is it available anywhere more accessible than jd.com?
The Magic Fox one looks like an unbadged version of WEB-U2 (more recently branded as WITRN U2)
There are very similar USB testers sold under several different brands and the relationship between them is not clear to me (e.g. YZXstudio, WITRN, WEB-, POWER-Z, AVHzY)
I found another YZXstudio DC-PD adapter on ebay ZC823x3 (it’s also on their Taobao store): 180W, 6 ports arranged as 3 x 60W USB C/USB A pairs, and DC or PD input.
If you’re willing to pay pretty penny I’d recommend YZXstudio zl1100, it can trigger every charge protocol, 0-3A ramping, serial data logging and up to 60W PD (indefinitely with the correct cooling conditions).
Everything is managed via the integrated OLED screen but you can easily translate the serial data into graphs with jcharts or similar tool.
