LED Display for Vehicle Voltage and Charging Amperage
The cool white LED display is easy to read yet is not harsh on the eyes. A solid LED read out displays your car’s operating voltage or the total USB charging output. When not charging a device, the easy-to-read LED screen displays the condition of your battery/charging system. A flashing display indicates a potential vehicle voltage problem - High or Low voltage can indicate a battery issue. When charging a device, the amperage will be displayed to show how much power your device is drawing.
