MULTIPLE FUNCTIONS:

1. Screen rotation function: Press the button on the back, the display interface can rotate 180 degree.

2. 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.

3. Over- & Under- voltage reminding: When the voltage is over 5.3V or less than 4.7V, there showing flashing arrow(^ 0r ˇ), and will automatically disappear when voltage within 4.7V-5.3V.

4. Support QC2.0 technology, great for monitoring Qualcomm Quick Charge 2.0 chargers, power-banks and devices.
