The scoop: PowerCup 200 Watt Inverter with USB Power Port, about $35.
What is it? Shaped like a large-size cup of coffee that you'd get at Starbucks or Dunkin' Donuts, the PowerCup fits nicely into your car's standard cup holder slot. But instead of coffee, tea or hot chocolate coming out of the cup, instead you get power for your mobile devices.
Why it's cool: The PowerCup lets you power up two regular "household devices" through its regular power ports (basically you could power a laptop, DVD player, blender, fan, etc.), as well as one USB-powered device (think iPod, iPhone, iPad, etc.). The PowerCup itself is charged via your car's cigarette lighter adapter, so as long as your cup holders are near the cigarette lighter port, you're good to go.
Some caveats: Be careful that you don't accidentally grab the PowerCup on your morning commute instead of your hot beverage. Or spill your coffee into the PowerCup.
