If you're like me, you've at some point wondered why nobody thought to include "standard" electrical outlets in your car. The bad news is that there's no solid answer to this question. The good news is that someone out there with more technical knowledge (and motivation) has decided to do something about it.

Calling it the Coffee Cup Inverter, this conveniently shaped power source coverts your car's DC power into two 120-volt AC outlets just like on your walls at home.
Perhaps even more clever is the fact that it's shaped just a like a cup of java from your favorite drive-thru window so as to fit nicely in your car's cup holder.

Perfect for powering or charging portable game consoles, cell phones, and iPods or even to plug in and watch television during the camping trip. It also has a USB charging port providing 500mA.

It sells for around $29 and the only question that remains is. Why didn't I think of that?
