Theo Power is an ingenious smartphone case that is equipped with wireless charging technology as well as a back-up battery pack which can be used to charge your phone.
The Theo Power case's battery can be removed to enable seperate charging, but users also have the option of charging the case and phone via cable and wireless charging in order to achieve reduced charging times. The case's battery can be charged simultaneously along with the phone, although the technology is set up in such a way that the phone is always charged first before the case.
The device can also be used for charging any other devices who have a compatible port. For example, the Theo Power case for iPhone 5 can also be used to charge the iPad Air and iPad mini.
