[THANK YOU, WE HAVE A WINNER! THIS CONTEST IS CLOSED. CONGRATS TO FAITHFUL MACENSTEIN READER VINCENT!]

When you think about it, batteries may be the single greatest invention ever. They give us the freedom to use our electronics virtually ANYWHERE, completely freeing us from having to interact with other people. And probably the greatest battery of them all comes from Mophie, makers of the Juice Pack line of iPod and iPhone external batteries. And probably the greatest battery that Mophie makes is the Mophie Juice Pack Air, the super slim battery and iPhone case combined into one sleek, stylish, black, white, or purple case.

If you have an iPhone 3G, you want the Juice Pack Air. Why? Well, because the iPhone eats batteries for breakfast, and odds are you want an iPhone that still works well after lunchtime. The Juice Pack Air is a rechargeable external battery concealed inside of a protective form-fitting case for the iPhone 3G. It offers you the full protection of a hard-shell case while providing virtually twice the battery life of the iPhone alone; all in an ultra-thin, light-weight, low-profile design.
• The world’s thinnest Apple certified “Works With iPhone” external battery for iPhone 3G and 3Gs!
• Rechargeable 1200mAh lithium polymer battery virtually doubles your time to rock, talk, surf and send.
• Pass-through USB charging and sync with iTunes
• Extended smart battery and full case protection
• On/Off switch offers choice of battery or case
• Integrated 4 LED charge status indicator Iight combines nearly all the battery charging goodness of the Juice Pack (almost doubling your iPhone’s battery life) while protecting it inside a protective form-fitting case.

To enter: Batteries do nothing but bring joy to all that behold them, and are responsible for so many wonderful memories. So this week in order to enter, simply tell us what is the best battery powered item you own, or ever owned? (Keep it clean, people). Was it the giant AT-AT star was toy as a kid? Your digital camera? A Zune? Contest ends July 27th, and one winner will be picked randomly (US residents only this time, sorry folks). Good luck, and thanks for reading Macenstein!
