I can’t begin to explain how much a dead battery irritates me. I have been in the market for a good external battery and for $2 this one is a steal!
Here’s the deal: $2 for a mobile power pack for Apple devices. Ideal for road trips and outdoor days, this low-profile charging pack (about 6 inches wide) boosts everything from your iPhone 4s to your iPod. So you’re unplugged, but not out of touch.
$6 flat-rate shipping and handling applies per power pack; code cannot be used toward shipping.
I was reading the Q&A and on a dead battery this should charge your iPhone up to 1/3 – 1/2.
