    Wireless Charging Coils

    Wireless charging coils are used for inductive charging and wireless charging. Wireless charging coils are installed into a device for the purpose of receiving a wireless signal that will be used to charge and power another device. They are a popular method for charging smart phones and tablets as they are not required to be plugged in, like a traditional charger.

    The coil is optimised for inductive charging. Wireless charging coils use an electromagnetic field between two devices to transfer energy. There are two functions, a transmitter and a receiver, with one beaming the field and the other receiving it. The transmitter and receiver must be on the same frequency. Please note that only devices with a compatible battery that will accept this type of charging.

    Where are wireless charging coils used?

    Wireless charging coils are used to charge portable devices such as:

    • Smartphones
    • Tablets
    • Wearables i.e. smart watches
    • Fitness trackers
    • Smart home i.e. heating controls
    • Medical devices
    • Clean rooms
