Having been electrified, the module can detect the voltage in real-time. When you need to charge your digital products, like mobile phone, Ipad, MP3 and so on, you can touch the sw2 button slightly. Meanwhile, the USB power LED lights up and the USB voltage output is 5.0V. Once you need to turn off the 7-segment display, press the sw1 button softly and the module will be in the standby mode with ultra-low power consumption. And the USB output stops.
