Air Power Bank $1

We find most people fall in love with their battery packs once they see how easy it is to charge their phone. We invite you to try the battery pack for $1 for 30 days. Despite being only 9mm thick and weighing less than 1/2 pound, the Air battery will recharge your smartphone 3 full times at the same speed as a wall outlet. No hidden fees, and there's no 'catch'. One month after your purchase if you're both getting along, we'll charge your card once for the remaining cost of $49. If you're unsatisfied (and enjoy your phone dying), simply send it back and we'll cover the return shipping to our headquarters.
