This one might be your best bet:

That bare board has great specs, but I find it hard to believe it would be able to handle 60W of output at lower range of input voltage for long times, say 12V which is 5A+ constant input, chargers usually get quite hot at that rate.

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.
I plan to feed it with 20V. The Lenovo 135W charger looks like great target. https://www.reddit.com/r/thinkpad/comments/bpnc9o/the_p1x1e_small_135w_charger_available_retail/

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 ?

If I want to test the maximum output of a charger, which adjustable load can I buy? Some recommendations?

I’ve found a new meter similar to YZXstudio ZY1280, is it a copy or is original?

I’d suggest a load with more power than your charger can use. With USB, 35W are usual:

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 have the RD LD35
https://www.aliexpress.com/item/32882318330.html
This is just a load: if I want to do triggering, I prefer to do it separately.

this is our LD35, it don’t have trigger function, if you need trigger function, you can check our other version HD35

I believe it has only QC trigger function. It would be great to have a load that also had PD trigger function.

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.
https://www.ebay.com/itm/ZC823x3-PD-180W-Multi-Protocol-Fast-Charge-Apple-Xiaomi-Huawei-Samsung-QC4-PD3/133054595939
I ordered one.

Do you plan to release a usb load with PD trigger and higher power capability?
Yes, I’d love one.
I’d also be willing to pay a pretty penny for one.
