This USB Power Meter is a versatile little tool that can provide voltage readings down to 0.01V and current to 0.001A, displayed on the built-in color TFT LCD, while your device is connected through it to a power source. You can also measure the capacity and power of battery packs/power banks as well as temperature and cable impedance!
In addition to the main numeric measurement interface, you can also toggle to voltage and current bar graph interfaces (because who doesn't like a good graph?), quick charge identification mode, wire group impedance measurement, and a simple settings screen. And with the recording option, you can easily record your data. Mmmmm data...
If you notice your USB Power Meter is not turning on when connected to a USB Type-C power source that can deliver multiple voltages depending on what device is connected, simply plug in whichever device you want to measure the power consumption of and the USB Power Meter should turn on. The issue seems to stem from USB Type-C handshaking protocol to confirm the proper voltage for a device attached to a USB Type-C power supply. The USB Power Meter passes these connections through the USB C input to a device connected to one of the outputs so without a device connected to the output of the Power Meter, it does not know what voltage to request from the power supply and will not turn on.
If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics.
Skill Level: Competent - You will be required to reference a datasheet or schematic to know how to use a component. Your knowledge of a datasheet will only require basic features like power requirements, pinouts, or communications type. Also, you may need a power supply that?s greater than 12V or more than 1A worth of current.
