Great Scott! This USB Car Charger looks like a Flux Capacitor from the Back to the Future series! Each Flux Capacitor Car Charger has two USB ports, each capable of charging almost any USB powered device (1 x 1A and 1 x 2.1A), plus it lights up! Flexible arm pivots up and down so you can better customize it to best fit your vehicle's power port placement. Compatible with anything that charges via USB (iPhones, smartphones, iPads, tablets, GPSes, etc.) as long as you have the cable. Dimensions: Flux Capacitor unit: 2.5" x 3" x 1", Power Plug: extends 3.5" out the back of the unit.
