ReVIVE PowerUP DV2 Dual USB Car Charger. Dual USB Smart Charging - Dual USB ports allow you to charge two devices at once. With both 1A and 2.1A ports, you can conveniently charge output specific devices. Smart charging technology identifies your device to deliver maximum charging currents for each device. This powerful charger offers protection that you can count on including overcharge, overheat, and car over/under voltage warning. LED Display Screen - The easy-to-read LED display shows the voltage/amperage of the devices you are charging as well as your vehicle. A solid LED read out alternates between displaying your car?s operating voltage and the total USB charging output. A flashing display indicates a potential vehicle voltage problem. Sleek Design - The DV2 not only looks great but also offers convenience with its premium design. Measuring only 2.3x1.4", it fits in the palm of your hand.
