Features:

1, this product can measure the USB power supply equipment when empty, the load voltage, the USB terminal voltage and current at work.
2, current and voltage loop display, use simple convenient and practical.
3, small easy to carry, no other power supply.

The electric energy meter adopts a new generation of four and a half double integral type conversion IC, equipped with precision band gap reference source, accurate range and high precision, stable work, reliable performance, strong anti-interference ability, high temperature resistance.Can be used to measure the USB interface, mobile phone charger, USB products such as power supply or power consumption.

It can easily measure the USB port of the output voltage and device working current!(please note: it can only display to work with real time of electric voltage and current according to the facts, do not have to put all of the functions, namely cannot set the xyz voltage to current discharge!)

Small size, no need for power supply and other ancillary equipment, plug and play!
