I found this unit on Ebay at a dealer called lakeyx101.



How does it look

The four digit display is used to show both voltage and current at the same time, this means only one digit after the point.

The box did not use any screws, I only had to pry the top off.

The resistor is a wire, not a smd component.

The trimmer is used to trim the voltage display.

Measurements

Test

Red means flashing display


Temp739

M1: 47,4C, M2: 52,6C, HS1: 65,1C
The resistor do get fairly hot, this is because it has a "high" resistance.



Conclusion

The usb meter has a fairly high internal resistance and the resolution is low with only one decimal place.
This usb meter works fine enough, but there are better devices.
