All car owners should know that electric appliances, such as power switch, spark plugs, and other internal electronics can be gradually damaged if the voltage is too high (exceeding normal value by 15%). Similarly, cars will not work proplerly if subject to under-voltage conditions (lower than 10% of threshold). The Volthermo 3.1A Dual USB Car Charger with LED Display is a Mutifunctional Tool for
you car! It Charges different mobile devices such as iPhone, Android Smart phone, iPad, Camera, PSP, etc. Built in LED Display present to you Voltage, Amperage, and Celcius temperature of your car. This allows you to be more conscious of your vehicle and devices you're charging. Every ten seconds, the display switches between voltage, total amperage of the devices you are charging, and internal temperature. Features:
Digital LED VAC Display - VAC stands for Voltage, Amperage, and Celcius. Be in tune with your vehicle - This device is one of the most helpful gadgets you can buy for your car. The voltage indicates the health of your battery/alternator and allows you to know when it's time for a replacement. The temperature helps you to manage the internal temperature of the car. The amperage keeps you informed of the amount of amperage your devices are using. Overcharge / Overheat Protection - The device auto powers off when input/output is greater than safety current. This ensures that your devices are protected against over-heat, over-current and over-charging. It detects the ambient temperature when not charging any device. Combined 3.1 amps; 15W; uses smart technology to ensure each device pulls the right amperage. Charger is powered by the vehicle's cigarette lighter. Auto power off when input/output is greater than safety current, protects against over-heat, over-current and over-charging
LED digital luminescence tubes;
The LEDs are bright enough to read the display without being a distraction while driving. Available in Red and Blue LEDs.
