Kensington battery packs for iPhone

As someone who regularly runs his iPhone battery all the way down I was interested when Kensington announced two new external batteries for the iPhone. The standard battery pack and charger is a larger stand-alone battery that connects to the iPhone via a dock cable and offers "playing time up to 100 hours of music; 21 hours of video; 6 hours of talk." Personally, however, I find the smaller mini battery pack (pictured right) more intriguing since it simply plugs into the dock connector and offers up to 3 hours extra talk time.

The standard battery pack is available for $69.99 while the mini battery pack is $49.99.
