“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.”
Since my iPhone’s battery isnt that good it actually goes low after around 1hr of internet usage so I searched for an alternative solution since the iphone’s battery is irreplaceable and no bigger battery can be added, so I found an article about this product and after checking the website out, I really liked the idea that a skinny hardcover protection can be used also as an external battery to extend the iPhone’s battery, it actually doubles the usage of the normal battery
Mophie is offering two juice packs for $99 but its a bulk hardware cover to be used with the iphone, the other one is Juice pack light which is much thinner and lighter than the normal juice pack and it comes in 3 colors white, purple and black. the product is for $79.95 and it’ll be available in sprint 2009. you can pre-order it now from their website
