Abstract
A power supply device includes: a plurality of resonant coils each having a resonant portion and a power transmission portion electrically connected to the resonant portion, the resonance portion receives electromagnetic waves of a different frequency, and converts electromagnetic waves of different frequencies into electric energy; and a power converting unit electrically connected to the power transmission portion to receive the electrical energy from the power transmission portion, and storing the electrical energy. A user uses the resonant coil to generate power by the resonance of the resonant coil with the electromagnetic waves in natural environment, and the power is stored in the power converting unit. The electric power converting unit does not need to store electricity through the power source, and only needs to use the electromagnetic waves in the environment to generate electrical energy, which facilitates the user to store electricity in the power converting unit.
