The Talk & Charge [$60] for the iPhone 5/5S/5C is an ultra-slim 3000mAh portable battery that fits behind your phone perfectly. It has a built-in lightning cable to give you 13 hours of additional talk time. It mirrors the size of an iPhone 5 to fit perfectly in your hand. The Talk & Charge weighs just 3.2 oz so when you’re done using it, you can easily slip it into your back pocket and go. The unit comes fully-charged and ready to use right out of the box. This is my go-to charger because of it’s simplicity and performance. It has been thoroughly Uber-Tested and is Uber-Awesome! They sell them at Best Buy.
