shockley Battery Voltage Indicator 0.56" LED Voltmeter + Dual USB Output car bike (1 Pc) Voltmeter  (Digital)

12V Universal Dual USB Digital Voltmeter and Battery Indicator Display Module is a Digital Battery Voltmeter Indicator with Dual USB 12V To 5V Step-down is a high quality, accurate, and affordable device that can be used to measure the voltage of any DC power source. This device has an easy to read digital display with a maximum of 3.3 volts. The device comes with two USB ports, conveniently providing 5V power output. You can charge multiple devices simultaneously, such as smartphones, tablets, GPS devices, and more, making it a practical companion for long journeys or camping trips. The step-down function efficiently converts the higher 12V input voltage to a stable 5V output, ensuring a safe and reliable charging process for your USB-powered devices. Its compact design allows for easy installation in your car, boat, motorcycle, RV, or any other vehicle with a 12V power supply. It takes up minimal space while providing valuable information and charging capabilities. This device is suitable for a wide range of vehicles and settings, providing invaluable voltage information and convenient charging options for your devices during travels, outdoor adventures, or daily commuting. Suitable for all kinds of outdoor power, mobile power, instrumentation and other equipment Features:- Static Input Current: 5-25mA,the lower the battery voltage, the smaller the current. USB Output 5V/2A(max), two USB port total is 2A(a USB setting for Apple recognition, a USB setting for Android recognition) USB step down efficiency is up to 96% (because of the synchronous rectification circuit, the buck conversion efficiency is high and the heat is low. 8 segment power resolution: 10% 25% 40% 50% 60% 75% 90% 100% The accuracy of the voltmeter is about 2% Working Temperature: -10~+65? Working Humidity: 10-80% (no condensation) Uses synchronous rectification step-down chip scheme, energy saving
