If you complain about your iPhone or Android phone running out of battery at the most inopportune times, you need a backup battery. But which one do you buy? They come in all shapes, all sizes and all capacities. But the one thing the Powerskin PoP’n backup battery pack has going for it is the fact that it’s only going to cost you 1 cent (not including shipping) if you order before May 16th at 11:59pm (ET) when the offer expires. The Powerskin PoP’n backup battery pack isn’t an ordinary battery pack that requires a USB cable for connection to your phone. This one has been designed to stick to the back of your phone with suction cups. It features a 2000mAh capacity battery in a thin design with a micro USB, 30 pin iPhone or lightning connectors. The PoP’n is available in versions for the iPhone 4/4S, iPhone 5/5s and a variety of Android phones that have a micro USB connector. I’m assuming that the iPhone 5/5s version also works with the new iPhone 6 and iPhone 6 Plus phones. To buy this battery pack for only one penny, visit Powerskin.com and use the promo code ONECENT. You will still be responsible for shipping which is $9.99 at the low end and up to $38 if you want overnight Fedex delivery (these are the shipping charges I saw when I tested the ordering process so they may be different depending on your location). Act fast if you’re interested in getting this deal because I’ve noticed at least one version is already on back order.
