1. Convenience: There is no need to connect with wires when charging, just put it near the charging appliance. When there are multiple electrical devices, multiple chargers can be saved, multiple power sockets are not occupied, and multiple wires are not entangled with each other.
2. Safety: There is no energized contact design, which can avoid the danger of electric shock.
3. Durable: Because the power transmission components are not exposed, they will not be corroded by moisture and oxygen in the air, and there will be no loss caused by mechanical abrasion and flashover during connection and separation.
