This module efficiently converts an input voltage range of 4.5-40V into a stable 5V output with a maximum current of 2A, perfect for charging devices via its USB port.\u003cbr\u003e\u003cbr\u003eTo use, simply connect the module to a power supply, and it will display the real-time input voltage on the built-in voltmeter. Press the \"Output Enable\" button to begin charging devices like phones, iPads, and MP3 players at a regulated 5V 2A output. When not in use, the \"Low Power\" button activates ultra-low-power standby mode, turning off the USB output and conserving energy.\u003cbr\u003e\u003cbr\u003eThis step-down converter is ideal for applications such as monitoring battery voltage in cars, motorcycles, and other vehicles, as well as for general voltage measurement in various scenarios. With its reliable 5V 2A output, it meets the charging needs of a wide range of USB devices.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eNote:\u003c\/strong\u003e\u003cbr\u003e\u003cbr\u003eThis module defaults D + D- short, most of the cell phone charger is compatible, and set aside a variety of mobile phones identification resistor installation location, if you need to add the identification resistor, please connect D + D- wires cut, then added.\u003c\/div\u003e\n\u003cdiv class=\"product_info\"\u003e\n\u003ch3 class=\"sing--sub-heading\"\u003eVoltmeter Calibration Method\u003c\/h3\u003e\n\u003cdiv style=\"text-align: left;\" id=\"p_info\"\u003e\n\u003cul class=\"pro-ds\"\u003e\n\u003cli\u003e\n\u003cstrong\u003eStep1\u003c\/strong\u003e: Press the “Output Enable” button more than 2 seconds, release, voltmeter flashes, this time into the voltage regulation mode;\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStep2\u003c\/strong\u003e: Press the “Output Enable” button (normal speed), the voltage value is adding up a unit; Press the “Low Power” button, minus a unit; Due to a unit is less than 0.1V, the minimum voltage display to 0.1V, so you need to continuously press 1-5 times to see the voltmeter change 0.1V, how many times voltmeter change 0.1V by pressing the button, depending on the current display voltage, the higher the voltage, the fewer the number of press.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStep3\u003c\/strong\u003e: press the “Output Enable” button for more than 2 seconds, release, to exit the voltage calibration mode.
