Mophie iPhone 4 / 4S Juice Pack Air Charging Case - Refurbished
Product Review (submitted on February 26, 2013):
I've used Mophie Juice Packs since my first iPhone which was the 3Gs. As one who uses his phone for audio and video recording, it's essential that my phone stays on for up to and beyond 8 hours of heavy use. The Juice Pak provides that and then some! The special price on the refurbished model was a no brainer for my iPhone 4.
