DC-DC 4.5-40V To 5V 2A USB Charger Step down Converter Voltmeter Module
Description:
Compact and efficient DC-DC buck converter module is designed to step down a wide input voltage range (4.5V to 40V) to a stable 5V output via USB, with a maximum output current of 2A. It's ideal for charging USB-powered devices or powering 5V electronics directly from a car battery, solar panel, or other higher-voltage DC sources.Equipped with a digital voltmeter display, the module provides real-time monitoring of the input voltage, helping users quickly identify power input levels and avoid overvoltage scenarios. This feature is especially useful in automotive or DIY battery-powered projects.
Features:
1. Wide input voltage range supports a variety of power sources (car batteries, solar panels, etc.).
2. Fixed 5V output ideal for charging phones, tablets, cameras, and microcontrollers.
3. USB-A port ensures compatibility with all standard USB cables.
4. Integrated LED voltmeter for easy voltage monitoring.
5. Compact size, suitable for portable or embedded applications.
6. Built-in safety features ensure reliable and durable operation.
