After the module is energized, it can detect the voltage in real time. When you need to charge the phone, Ipad, MP3 and other digital products, touch the ''output enable'' button, then USB power indicator light, USB output 5.0V voltage; when you need to turn off the digital display, touch ''Low power'' button, then the module into the ultra-low power standby mode, USB output is also turned off accordingly.
Ultra-wide voltmeter range: DC4.5 - 40V;
5V / 2A output current capacity (input voltage in the 6.5 ~ 40V when the output can be stable 5.0V);
With reverse polarity protection, overcurrent protection, over temperature protection.
Voltmeter can be self-calibration, there is no voltage meter is not accurate problem.
