4/Feb/2018 UPDATE: This thread has been repurposed to include more brands and models into it. YZXstudio is no longer the only company to make high quality USB testing devices. New brands such as Power-Z, AVHzY and RUIDENG have come up with many interesting products
. Quick links to popular power meters:
-$20 and less
-RUIDENG UM24: USB-A/Micro, QC, Bluetooth (opt), Offline logging: Banggood
I have spoken with Franky (probably the main overseas distributor for yzx products) and he tells me the Y1270 color oled version is still in its very first FW versions, and that it’s best to wait for a couple upgrades to have bugs sorted out and get a more accurate calibration. Anyways I think one could upgrade it at home with an ST usb programmer, the new FW archives are posted on chongdiantou chinese forum.
Here’s the Y1270 with some more specs on the official store: taobao | 淘寶
I also ordered some interesting yzx products that I will review once they arrive, a YZX 7th gen 4-cell powerbank, the fan-cooled usb dummy load and the new Y1266 meter.
You’re right but communication with him is really easy and quick, he also provides a custom translated user manual and flashes the meters to the latest FW version available before shipping. Some other sellers don’t even know which version they’re shipping…
To buy from taobao you can use mistertao agent, but the only time I used it the item took 3 months to arrive, and they don’t accept paypal.
