Product Description

This Mini Power Meter with Voltage, Current, Watts, mAh & mWh Display (whew that is a mouth-full) is a lot like the USB In-Line Voltage and Current Meter we carry but can  be used with a wide range of voltages (not just USB connections). Measure the working voltage and current output for any project with this really fancy power meter.

This power meter has an small LCD display that shows off voltage, watts, amps, and mAH and instantly reads the numbers out for testing devices, such as chargers, cables, and cell phones. There's a few nice extras in this very fancy monitor, such as showing the impedance of the connected device as well as calculating the cumulative Watt-hours and milliAmp-hours over a running time. Basically it's an all-in-one power management solution that doesn't require any calculation or data logging on your part.

You can have it self-power from the power source it's measuring (it has a quiescent of about 20mA and requires at least 3V) or you can power separately from a JST connector or power-only micro USB socket.

Comes with

  • 1 x 2-pin JST Connector 
  • 2 x Positive Alligator Test Clips
  • 2 x Negative Alligator Test Clips
