The listing, Maxboost Charging Case for I-phone 5 has ended.
I got this on Listia about a year or so ago. I used this maybe 10 or 12 times and it works great. The blue lights pictured indicate a full charge. Put the case on and when your phone runs low press the button until the lights come on. It charges faster than plugging into a wall outlet and you can use the phone as it is charging. To charge the case itself use the cord pictured with any USB plug or car charger you can leave your phone in the case and charge both at the same time. I have since upgraded my phone and this case does not fit the new phone. My loss is your gain, shipping is free!!
