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 a 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 are a few nice extras in this very fancy monitor, such as showing the ambient temperature and 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 * 1 x NTC Temperature Sensor Technical Details Revision History: * As of June 23, 2020, this power mini kit no longer comes with positive and negative alligator clips, but now includes an NTC temperature sensor.
