1. A wireless power transmitter that wirelessly transmits power to a wireless power receiver, the wireless power transmitter comprising:
- a cylindrical housing,a power supply; and
a power transmission unit that wirelessly transmits the power to the wireless power receiver based on a first power received from the power supply,wherein the power transmission unit comprises a first capacitor, a first coil connected to the first capacitor, a second capacitor, and a second coil connected to the second capacitor and physically disposed in parallel with the first coil,wherein the wireless power receiver is mountable on an outer surface of the cylindrical housing with a curvature corresponding to the outer surface of the cylindrical housing, and is positioned between the first coil and the second coil, and a diameter of the first coil corresponds to a diameter of the second coil,wherein a receiving coil of the wireless power receiver is oriented vertically with respect to the first coil and the second coil, andwherein a first portion of the cylindrical housing contacts the wireless power receiver while the wireless power receiver is mounted on the cylindrical housing, and the first portion of the cylindrical housing constitutes a circumference between the first coil and the second coil such that the first portion is parallel with the first coil and the second coil.
