A wireless power system has a wireless power transmitting device and a wireless power receiving device. The wireless power transmitting device may be a wireless charging mat with one or more coils or may be a wireless charging puck with one or more coils. In some embodiments, the wireless charging puck may have six coils or other number of coils arranged in a ring. The wireless power receiving device may have an elongated magnetic core such as a C-shaped core with pillars at opposing ends. First and second coils may be formed on the pillars and a third coil may be formed between the first and second coils. The coils of the wireless power receiving device such as the first and second coils on the magnetic core may be configured to receive magnetic flux emitted by a pair of the six coils in the wireless charging puck.
