Benchmark Reviews posted a review on the Arctic Dual USB Car Charger

People love their portable electronics, and can't get escape without their phone, tablet, and digital multimedia devices in tow. We take our ebook readers with us everywhere, carry a Bluetooth wireless headset for calls on the road, and occasionally find time to take pictures with the digital camera. All of these devices require power, and when you're away from home it's hard to keep batteries charged during long trips or after prolonged use. Every vehicle has a 12V cigarette lighter receptacle, but most lack USB power outlets. Arctic Cooling offers the Dual USB Car Charger (model PSAEQ-AC01901-BL) to keep your devices working while on the road, with two USB ports and the ability to fast-charge at up to 2.1 amps of power.

Perfect for older-model vehicles that lack factory-installed USB power outlets, the Arctic Dual USB Car Charger is an easy upgrade that fits into the standard 12V/1A DC receptacle. Since I don't smoke, the 12V cigarette lighter receptacle on my car is rather useless. By adding the Arctic Dual USB Car Charger, I can easily update my vehicle and get more use out of portable electronics when I travel or take long road trips. This is ideal during extended travel, when battery power for items like the Apple iPad or iPhone runs low after a movie.
