Old APC Mobile Power Pack Can Recharge an iPhone 4 or iPad

I bought my APC Mobile Power Pack several years ago for about $50 (if memory serves me correctly). I carry it with me nearly everyday even though I only use it a couple of times a year (think of it like a spare tire). The card pack sized device is small and light enough that I don’t mind carrying around. It has served me well the few times I’ve needed it recharging Windows Mobile phones, Android phones and even my iPhone 3G.
