New Trent Easypak 7000mAh Portable Triple USB Port External Battery Charger/Power Pack for Smartphones, Tablets and more (w/built-in USB cable)
I purchased 2 of the IMP500 over a year ago when I was flying coast to coast so I could arrive in DC or home and have full batteries on my head sets Ipod and Iphone after using them for 12 hours. I was not disappointed and love them I have tried other options in the past and none compared to this. I was also happy to find out it even kicked my Ipad in to charging mode when I tried it. If you travel at all this is a must !!
