There are so many third party power inverters for cars now days. The problem is, they all have awkward sizes and don’t fit anywhere convenient. If you don’t screw is down somewhere, they just bounce around and get in the way. The PowerLine 0900-66 has the answer as it’s designed to fit in a cup holder. They even made an effort to make it look like a coffee cup. The PowerLine provides 200 watts of continuous power (400-watt peak) via two 120 colt AC outlet and USB ports. Power the mp3 player, laptop or even the toaster.
