This DC-DC 4.5-40V To 5V 2A USB Charger Step down Converter Voltmeter Module, is an integrated circuit with 2A Charger and voltage checker.In this module, by connecting to the power the voltage can be detected in real-time.
When you want to charge the phone, IPAD, MP3 and other digital products click the “Output Enable” button. Then USB power indicates lights, and USB output voltage 5.0V. By clicking on the “Low Power” button, you can turn off the voltmeter. Thus enter the ultra-low-power standby mode, USB output set to the corresponding shutdown. It offers wide input voltage, for car/battery car/motorcycle used for monitoring battery voltage. Hence measure the voltage needed for a variety of occasions. The output current capability 5.0V/2A, enough to satisfy a spread of USB devices, voltage is extremely stable.
The module converts an input of 4.5-40V into a really stable 5V 2A output. The device features a USB port through which you can charge your phone. While charging your device please consider that the output of this device is regulated at 5V 2A. This module features reverse connection protection, overheat protection, and short circuit protection. Thus achieves high efficiency and low ripple performance.
Note: This module is compatible with most of the cell phone chargers when default D + D- short, and set aside a variety of mobile phones identification resistor installation location. In case if you need to add the identification resistor, please connect D + D- wires cut, then add.
