1. A system for wirelessly transmitting power between a mobile device and a locking device, the system comprising:
a mobile device comprising:
a wireless power coil configured to receive power;
a communication module configured to wirelessly transmit an access credential; and
at least one battery configured to supply power to at least the communication module, the at least one battery comprising a storage of power, the at least one battery configured to store at least a portion of the power received by the wireless power coil;
a locking device comprising:
a wireless power coil configured to wirelessly transmit power to the wireless power coil of the mobile device; and
an authentication module configured to receive and authenticate the access credential, the access credential being received from the communication module of the mobile device, the authentication module operatively connected to a lock actuator, the lock actuator configured to lock or unlock a mechanical or electronic lock when the access credential is authenticated;
wherein the power is wirelessly transmitted from the locking device to the mobile device when the storage of power is below a critical level, and wherein
the authentication module of the locking device is configured to transmit a confirmation signal to the communication module of the mobile device when the access credential is authenticated, the confirmation signal comprising instructions to charge the at least one battery of the locking device, when the storage of power is below the critical level, and
the wireless power coil of the mobile device is configured to wirelessly transmit power to the wireless power coil of the locking device if the confirmation signal is not received within a threshold time.
