An extension wire with USB socket is an electrical device that allows multiple devices to be connected to a single electrical outlet. It typically consists of a cord with one or more power outlets on one end and a plug on the other end that can be inserted into an electrical outlet. In addition to power outlets, this type of extension cord also features USB sockets, which can be used to charge devices like smartphones, tablets, and other USB-powered devices. The cord length of an extension wire with USB socket can vary, but it is typically long enough to provide flexibility in positioning devices around a room or workspace. The cord is usually made of durable, fire-resistant materials that are designed to withstand daily use. Extension cords with USB sockets are useful in situations where there are limited power outlets, such as in an office or home workspace, or when charging multiple devices at the same time. They are also convenient for travel, allowing users to charge their devices without the need for multiple chargers or adapters.
