ABSTRACT:
A small-sized power package includes a tubular case, a magnet tube, a coil, a power-generating magnet, a shaft, a movable box, and a positioning magnet. The power-generating magnet is attracted by the positioning magnet and thus suspended within the magnet tube. The small-sized power package has enhanced power generating efficiency by utilizing the benefit of magnetic levitation. An electronic device including such a small-sized power package is also provided.
