1. A device for wireless power transfer, the device comprising:
- a power transmitting element configured to use a current at a first level to wirelessly transmit power sufficient to provide power to one or more chargeable devices positioned within a charging region; and
a controller operationally coupled to the power transmitting element and configured to;
adjust the current to a default level in response to detecting the one or more chargeable devices;
adjust the current to the first level from the default level, the first level being different from the default level;
detect a subsequent chargeable device positioned within the charging region while the current is at the first level;
adjust the current, in response to detecting the subsequent chargeable device, from the first level to the default level prior to communication with the subsequent chargeable device; and
adjust the current to a second level different from the default level to charge the one or more chargeable devices and to charge the subsequent chargeable device.
