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.

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!

Also detect any USB charger (computer USB, home charger, car charger) of the charging current and voltage, to judge the performance of the charger and charging line performance is in line with the requirements!

Applicability is wide and any phone, any electronic products, all can use, easy to operate, suitable for factories, laboratories and users!
