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

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.

Also maybe with solder pads or terminals for connecting other than USB devices directly without a USB adapter, since that’s a lousy connection.

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.

Too bad my first batch ZL1100 can’t trigger PD even with a newer firmware. Just says NG. So make sure you get a recent one.

for now , we don’t have plan on load, we are designing a big display, many button and function power supply

higher voltage is useless, big current is very important , HD35 have 5A current . 35W is enough
Yes, but higher voltage is necessary to test high power USB-C PD sources.
I mean, with a 3A cable at 20V, it goes up to 60W.
At 20V with a 5A cable, that goes up to 100W.
A 100W USB PD 3.0/QC 4.0 load would be large, but very useful for many years to come.
