Wireless charging is a technology of transmitting power through an air gap to electrical devices for the purpose of energy replenishment. Wireless charging technology gets power from a power source, like a charger, to a load, like a phone, wirelessly across an air gap, so there aren't any wires to get in the way. Power can be sent from one place to another wirelessly, without the need for wires or links.
