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

why you use photos of UM34C when you are talking about UM24C :question:

Most UT25 has been removed from Aliexpress, we should support originals instead of copies , otherwise it will cause loss to the original creator and they may never create new products

hello,when did you buy UM25C, the latest version supports OnePlus Dash Charge

Does anyone know of a prepackaged 60W DC to USB C thing? https://www.nicelineshop.com/index.php?main_page=product_info&cPath=&products_id=8369 this is just the bare board, I’d like a case with it, if possible

Googling for “DC to USB PD Converter” might help.

Here’s one https://www.omnicharge.co/products/dc-to-usb-c-adapter/

Another in stock: Amazon.com

Cheaper one (90W): Amazon.com

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.

so sorry, we don’t have

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/

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 jd.com?

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

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.
