If you’re looking for a USB car charger, Future Shop currently has the Kensington PowerBolt Dual USB car charger (3.1 amp output) for $19.99, which also comes with a Lightning cable. This unit is advertised to charge an iPhone 5/5S/5C plus another iOS compatible device, which includes the iPad 4 or newer, iPad mini or newer, iPod touch 5th gen, and iPod nano 7th gen.
How to nab it for $16.99? You need to do a price match at Best Buy since they are selling it for $49.99. After the price match plus 10 percent of the difference, it works out to $16.99 plus tax, which is pretty good deal since there’s a Lightning USB cable included. Good luck!
