The casing comprises a hidden compartment for storing a battery that charges the communication device. The casing further comprises a charging assembly that serves to charge and align the communication device inside the casing. The charging assembly transmits and converts electricity for charging the communication device. An alignment bar aligns the charging assembly and the attached communication device in the casing. Flexible tabs on the mount of the charging assembly, and springs on the sidewalls of the casing, absorb impact forces that are applied on the phone case and the contained communication device. Thus, the phone case provides dual charging means and a shock absorption. This enables the communication device to float in the x, y, and z axes of the casing, while still maintaining stability therein. ## Claims ### Claim 1 A case for providing multiple power sources and absorbing shock for a communication device, the case comprising: a casing, the casing defined by a panel, at least one casing sidewall, and a cavity, the panel formed at a back side of the casing, the at least one casing sidewall having an aperture;
