The Alpatronix BX114 is designed for the Apple iPhone 5C.

The BX114 works with your original iPhone 5C cable, so a charging cable or a USB wall charger are not included. The BX114 has overcharge protection and is available in a variety of fun colors. All of the phone's functions can be performed while it is in the case.

The case has a built in feature that stops the case from charging the phone once your phone reaches 100 percent, to prevent any damage to your phone battery. The Alpatronix BX400 has an easy to handle, slim design, and is available in black and white.
Battery cases are a great way to extend the life of your phone, reducing your need for a constant power source and juggling cords. The cases also provide all the protection you would expect from any phone case.
