USB power meter/tester thread - YZXStudio, Power-Z, RDTech and more.

hope you get the better one

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

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

Depends on the output of the charger you want to test :)
Here are some of the ones I use for my videos :

These are just loads, so you'll need something to trigger the protocol you need.

These are just my two cents, btw :)

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)

not , it is web-z meter , they are different

they are all USB load , but the first one is a trash

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.

for not , there is not PD trigger load

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.

I ordered one.

this is a charger, not a load, I just talked about the USB load

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.
