Extended batteries are a regular option from some laptop manufacturers, but MacBook and MacBook Pro owners have largely resorted to second batteries to get more than the stock amount of battery life. On Thursday, these Apple laptop owners were given a second option by power accessory maker Battery Geek. The 140 Watt/hour Portable Power Station is an external battery that now has an optional connector that supports both MacBook models and extends their portable runtime significantly: the company claims that even the power-hungry MacBook Pro can last up to 6 additional hours on the lithium-ion based adapter. The device can also charge iBooks and PowerBooks, most Windows laptops, and USB-powered devices, including the iPod. The Portable Power Station is currently shipping at an official price of $399.
