1.21 gigawatts! No, it won't take that much power to charge your phone, but it sure is fun to say! Pulled straight from the Back to the Future universe, this flux capacitor USB car charger looks good in more than just DeLoreans. Plug it into your car's outlet, hit the on switch, and watch as the officially licensed device comes to life. Lights pulsate throughout the body of the charger just like Doc Brown originally designed it, but be careful when you approach 88 mph.
