For this week's contest, I'm giving away a cell phone charger that plugs into the cigarette lighter in your car. You can use it with any gadget that has a USB-to-mini-USB adapter, and it has a flashlight on it as well. (More details here). The charger is made by a company called Flashlight-er, and it ordinarily costs $29.95 plus shipping and handling. To win, leave a comment below describing your favorite tech tool (and, ideally, how you use it in your business). If you already wrote about your favorite tool in last week's contest, go with your second-favorite! The contest is open until Friday at 5 p.m., and I'll use a random number generator to pick a winner.

Also, congratulations to Amy Ng of Fides Fashion, winner of last week's contest. Ng wrote about Google Analytics, but she uses another interesting tool as well: eCRATER, a Website where anyone can build an online store for free. She won the book AdWords for Dummies, which comes with an AdWords gift card worth $25.
