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

I can’t seem to find the power banks anywhere. Does YzxStudio still make them?

I guess that means no, the YzxStudio power banks are no longer available. Unless someone has a link to one

Hello there,

Updated the app:
should work with the ZL1100 load?
sample rate can be defined in settings, also path and logformat

But chart is not finished yet, therefore I removed the icon until finishing this function.

Download here

Nice! I’ll give it a go tomorrow when I get back home from the Netherlands.

Please download again, I fixed a small bug… Forget the chart icon, it displays something, but it is not working.

You’re welcome :slight_smile:

I updated the second link again, no idea why it doesn’t work. Checked all permissions at google sheets, everything the same as the file in the first link.
But you’ll find the information here too:

I got the last one from Franky, but sad to hear this great powerbank isn’t available anymore.

Hi! Franky Tong here :slight_smile: I’ve known about this forum through my customers for a while and finally decided to register for an account so I can post directly :slight_smile:

I contacted YZXstudio just now and they told me there’s no plan to stop producing their power banks (perhaps it was another product KAAYEE was referrring to?). They will continue to make and improve them. I’m not sure who else would sell and ship them outside of China though.

Second link doesn’t seem to work for me too. Possibly because the first one is “usp=sharing” while the second one is not?

Thanks! Was wondering if the DataExplorer opensource app can also be configured to work with the ZL1100 load tester?

Hi and welcome to BLF Franky Tong. Thanks for the update. :+1:

I‘m not the developer of Dataexplorer, and I don‘t prefer Java. So do you miss a feature in my app?

Not working for me with ZL1100. Says time out after trying to connect, same as with the original version.

I will add variable timeout setting, now it is fixed 2 seconds.

But the other zy is working or also broken? Can you please try to connect with putty? So when putty is working, then my app is fault, otherwise it‘s your zl1100. Anyone else here with a zl1100 for testing?

Regards
Patrick

Edit: my zy only times out when I display the chart screen on it, other screens don‘t cause a Time out

Putty or any other terminal program works fine with the ZL1100. ZY1270 also works with the new version.

Welcome to BLF Franky. If you happen to find out who could sell the power banks, let us know. I would think someone could sell quite a few of them if there was a solid place to buy them from, especially if they were converted to English.

Yea, great to have you here Franky :crown: :+1:

Pardon my ignorance, how does one connect a serial-USB adapter to the ZY127x meters? Does the ZY127x meter have to have the bluetooth module installed for this to work? Or just need to buy some kind of serial-to-USB chip and (temporarily) connect it to certain contact points of the ZY127x meter?

I also have the ZL1100 load tester, and getting same error message as maukka above.
I actually haven’t tried to connect the ZL1100 tester to the computer yet before, so it’s my first time to test it connected to the PC.
(I’m not familiar how to use Putty, but I searched and downloaded a free software called RealTerm, opened the correct COM port, and it started to log results on the window); I had to use “Run as Administrator” to get RealTerm to work:

The above image correspond to reading of 5.0097v, 0.1000A, 0.9869Ah, 11.3322Wh

The “CPS” status window fluctuates between 740 to 1110 cps.
Not sure if this will help in debugging your great app.

Find the 4 solder pads near the edge of the main PCB. Starting from the square one, connect the 1st, 3rd and 4th solder pads to the GND, RXD and VCC of your serial-USB adapter.

Thanks for your reply! Just need some more clarification… somewhat newbie here.

Let’s say I purchase something like this (PL2303 USB to RS232 cable adapter)

https://www.lazada.com.ph/standard-pl2303-pl2303hx-usb-to-ttl-uart-cable-module-4p-4-pin-rs232-converter-serial-cables-adapter-48443490.html

Then I connect the pins:

“1” = GND
“2” = (no connection?)
“3” = RXD
“4” = VCC

Is that right?

That’s correct.
