Inductive charging (also known as wireless charging or cordless charging) is a type of wireless power transfer that uses electromagnetic induction to provide electricity to portable devices. The most common application is the Qi wireless charging standard for smartphones, smartwatches, and tablets. The technology can also be used for vehicles, power tools, electric toothbrushes, and medical devices. The portable equipment can be placed near a charging station or inductive pad, without needing to be precisely aligned or make electrical contact with a dock or plug.
