Wagan's 150-watt SmartAC inverter

As frustrating as having to use inverters in your car is (your car generates DC electricity, which needs to be converted to AC, which is converted back to DC by your electronics), they can be such an awesome convenience. And even a couple of years ago you couldn't expect to easily get a 150-watt inverter, let alone one for $40, like Wagan's 150-watt SmartAC inverter. It peaks at a 450W surge; if you're using near that much probably means you've got a power strip and a mobile office all jacked in, which is both enormously stupid and totally awesome of you.
