You must already be wondering how a simple device like an ashtray can be USB powered. This device requires USB power to properly suck all of the delicious tar out of the air. When I'm sitting around at my computer smoking I would hate the thought of possibly getting smoke in or around my computer components, but I am more than happy to allow it to flow throughout my lungs. Fifty bones to further my quest to completely tar over my lungs while keeping my computer components smoke-free, sounds like a hell of a deal to me.
