± 5% Charging Coils | e絡盟 Hong Kong

Our range of wireless charging coils includes one coil, two coil and three coil devices, with inductance from 2.5µH to 47µH.Wireless charging coils are electronic components at the core of wireless charging technology; an approach which allows battery-operated mobile and portable devices to be recharged without need for cables or plugging in.Broadly, there are three types of wireless charging. There are charging pads that use tightly coupled electromagnetic inductive or non-radiative charging; charging bowls or through-surface type chargers that use loosely coupled or radiative electromagnetic resonant charging that can transmit a charge a few centimetres; and uncoupled radio frequency (RF) wireless charging that allows a trickle charging capability at distances of many feet.Both tightly coupled inductive and loosely coupled resonant charging operate on the same principle of physics: a time-varying magnetic field induces a current in a closed loop of wire.Qi wireless charging coils are important because they comply with the Qi charging standard. This is not the only wireless charging method available, but it's the first one that is supported by two of the largest and most-influential smartphone makers: Samsung and Apple.

Applications of wireless charging coils

Wireless charging is currently being used in many applications including:

Smartphones and wearable technology
Notebooks and tablets
Power tools and service robots, such as vacuum cleaners
Multicopters and electric toys
