An energy transfer console is configured to provide wireless power transmission for multiple portable electronic devices, each device is freely oriented relative to the console. The energy transfer console is also configured to be power self-adaptable by changing the power transmission level according to the number of devices simultaneously charged. Each device is disposed within the magnetic field for the purpose of charging the battery device. The energy transfer console contains a sweep generator to produce power transmission across a frequency spectrum. The number of devices charged is determined, and an optimum frequency for maximum energy transfer to each device is realized. A single combined optimal frequency is determined by employing the specific optimal frequency for each individual device. The sweep generator is synchronized with the single combined optimal frequency, and a power transmission level is adjusted according to the number of devices.
