This is the 40V variant of the DC-DC 4.5-40V To 5V 2A USB Charger Step down Converter Voltmeter Module in Buck Converter. Available at ₹149.86 (₹127.00 + GST) with free shipping across India.
Product Description
- This device combines a 2A charger with a voltmeter, capable of converting an input voltage range of 4.5-40V down to a fixed output of 5V 2A. It features a USB port for charging phones or other devices, though it’s important to note that the output is set at 5V 2A.
- To operate this module, connect it to a power source; the input voltage will then be displayed. To charge a device, press the “Output Enable” button, which activates the USB power indicator, and 5V 2A will be supplied to the USB port.
- For turning off the voltmeter, press the “Low Power” button, which puts the module into a low-power standby mode and deactivates the USB output.
- This module is ideal for monitoring vehicle battery voltage and providing power to various USB devices.
Features
- The voltmeter has an automatic calibration function.
- With reverse connection protection.
- With overheat protection and short circuit protection.
- High efficiency and low ripple.
- With USB power indicator light.
Voltmeter Calibration Method
- Step1: Press the “Output Enable” button more than 2 seconds, release, voltmeter flashes, this time into the voltage regulation mode;
- Step2: 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.
- Step3: press the “Output Enable” button for more than 2 seconds, release, to exit the voltage calibration mode. Data is not lost after the power failure.s-l1600
Application
- Cars and Electric Bikes
- Motorcycle for voltage measurement and to charge the phone

Applications & Use Cases
The DC-DC 4.5-40V To 5V 2A USB Charger Step down Converter Voltmeter Module is a versatile buck converter used across a wide range of applications including voltage step-down for electronics, battery-powered projects, LED driver circuits, microcontroller power supply, and solar power regulation.
Common use cases:
- Converting 12V car battery to 5V for USB devices
- Powering a Raspberry Pi from a drone battery
- Regulating solar panel output for charging
This product is ideal for electronics hobbyists, IoT developers, and power supply designers.
Technical Tip: Buck converters are more efficient than linear regulators (LM7805). Choose one rated for at least 1.5x your required current. Ensure input voltage is at least 2V above output.
