Product Description
PARAMETERS
USB meter is a highly practical testing tool for measuring voltage, current, time, capacity via your phone/USB cable or other electric device. It is a portable and handy device for you to detect the quality of the power source/ USB wall charger/ USB car charger anywhere and anytime you want.
Measure the output current(0A-3.3A) and voltage(4V-20V) of a USB power supply. With the multimeter you could know clearly the charging status of your phone or tablet and distinguish bad chargers and cables.
DETECTING, CHARGING WITHOUT HAMPERING EACH OTHER: Our multiple USB detector is not only a multimeter but also a USB charger supporting Qualcomm Quick Charge 2.0. It is compatible to all USB devices with 5V, 9V or 12V output and to devices such as iPhone, Samsung, Android, solar panel, etc. The USB signal line do not affect normal USB telecommunication.
LCD display ,clearly,Real-time monitoring of your state of charge,and display your battery capacity

MULTIPLE FUNCTIONS:
1. Power-off storage function: When power off, the accumulated MAH will be automatically stored. And the accumulated MAH will twinkle next time when item is power on. If the actual capacitance reaches 1mah next time when item power on, then the accumulated MAH last time will stop twinkling, and the screen display actual capacitance.
2. Support QC2.0 technology, great for monitoring Qualcomm Quick Charge 2.0 chargers, power-banks and devices.
