The working principle of the surge protector is based on a special component inside it - a metal oxide varistor (MOV), which is a nonlinear resistor material. Under normal operating conditions, the MOV has a high impedance value and conducts almost no current; once it detects that the voltage exceeds the preset threshold, its impedance will drop sharply, forming a low-resistance channel, and releasing excess energy to the ground wire. In addition, some advanced surge protectors will integrate other protective measures, such as gas discharge tubes (GDTs) and transient voltage suppression diodes (TVS), to further enhance the protection effect.
The design of the extension cord is very simple and intuitive: one end is a standard three-pin plug for plugging into the power socket on the wall; the other end is a series of neatly arranged sockets for various electrical device plugs. To improve the convenience and safety of use, many extension cords are also equipped with a switch button, allowing users to manually control the on and off status of the entire circuit. Some high-end models even integrate overload protection, short-circuit protection, and other functions, which can automatically cut off the power output when abnormal conditions are detected to prevent accidents.

What is a surge protector?
Surge protector is a device designed to prevent damage to electrical equipment caused by instantaneous high voltage shocks (i.e. "surges" or "bursts") in power systems. When the power grid is abnormally high voltage, the surge protector will respond quickly to absorb or divert this extra energy, thereby preventing damage to sensitive electronic equipment connected behind it. This protection mechanism is particularly important for precision instruments that are easily affected by voltage fluctuations.
The working principle of the surge protector is based on a special component inside it - a metal oxide varistor (MOV), which is a nonlinear resistor material. Under normal operating conditions, the MOV has a high impedance value and conducts almost no current; once it detects that the voltage exceeds the preset threshold, its impedance will drop sharply, forming a low-resistance channel, and releasing excess energy to the ground wire. In addition, some advanced surge protectors will integrate other protective measures, such as gas discharge tubes (GDTs) and transient voltage suppression diodes (TVS), to further enhance the protection effect.
Surge protectors are usually installed at the power inlet or directly connected to critical equipment to ensure that potential threats are intercepted the first time. It can not only deal with external surges caused by lightning strikes, but also handle internal surges caused by grid failures, switch operations, or when other electrical equipment is started. Therefore, in homes and offices, surge protectors are one of the important lines of defense to ensure the long-term stable operation of electrical equipment.
What is an Power Strips?
Power strips, also known as a multi-hole socket or multi-purpose socket strip, is a common home and office appliance accessory. It is mainly used to expand limited wall socket resources so that multiple electrical devices can be connected to the same power point at the same time. An extension cord usually contains one or more standard sockets connected to the main power socket through a longer wire, which is convenient for users to use electrical appliances away from the power source.
The design of the extension cord is very simple and intuitive: one end is a standard three-pin plug for plugging into the power socket on the wall; the other end is a series of neatly arranged sockets for various electrical device plugs. To improve the convenience and safety of use, many extension cords are also equipped with a switch button, allowing users to manually control the on and off status of the entire circuit. Some high-end models even integrate overload protection, short-circuit protection, and other functions, which can automatically cut off the power output when abnormal conditions are detected to prevent accidents.
In addition to the basic power supply function, the extension cord has a variety of variants to adapt to different usage scenarios. For example, some models have a rotating socket design, which is convenient for inserting large plugs without taking up too much space; some products with USB charging ports are particularly suitable for quickly replenishing power for mobile devices such as smartphones and tablets. Whether in the living room, bedroom, or office at home, power extension cord sockets can effectively solve the power consumption problem caused by insufficient sockets, greatly improving the convenience of life and work.
