A power strip is also known as a power board. It allows people to connect multiple electronic devices to a single wall outlet. According to electrical safety organizations, a power strip is a portable outlet box used to connect devices. They connect to branch circuit outlets. These devices allow multiple devices to draw power from the same power source. Most power strips operate at 250 volts AC or less and 20 amperes or less. They must comply with safety regulations, such as the UL 1363A standard, especially in hospitals. The terms ‘power strip’ and “power board” are used interchangeably to refer to the same thing. Both provide additional outlets, but neither prevents power surges.
Power strips have several main uses in homes, schools, and offices. The table below lists the main functions and their meanings:
| Function | Description |
|---|---|
| Multiple Device Connection | Allows multiple devices to be connected to a single outlet, making it easier to use multiple electronic devices together. |
| Outlet Expansion | Increases the number of available outlets in a room or workspace. |
Power strips do not prevent voltage surges. Their primary function is to provide more power outlets for everyday use.
People use power strips wherever they need more power outlets. Students use them in dorm rooms to connect desk lamps, laptops, and chargers. Offices use power strips to connect computers, printers, and monitors on desks. Homes use them in living rooms or kitchens to connect TVs, game consoles, and small appliances. Power strips help organize wires and keep spaces tidy. They are best suited for connecting low-power devices that do not require surge protection.

A surge protector protects electronic devices from damage caused by sudden voltage spikes. Some people think it’s just like a power strip, but that’s not the case. A surge protector does more than just provide extra outlets. It prevents power surges that can damage computers, televisions, and other devices. When a power surge occurs, the surge protector acts like a shield, blocking or diverting the excess current. This helps prevent fires and extends the lifespan of electronic devices. People use surge protectors to protect valuable items.
Surge protectors have special components inside to handle power surges. These components provide a path for the excess voltage, diverting it away from electronic devices. They convert the excess voltage into current and direct it to the ground wire. This prevents the surge from damaging your equipment. Surge protectors are the first line of defense against surges. They can absorb harmful energy even from large surges. Some surge protectors plug directly into wall outlets, protecting individual devices. Others are installed in electrical panels, protecting entire rooms or buildings. Newer surge protectors use self-healing components and nanomaterials. These technologies help extend the lifespan of surge protectors and improve their performance.
| Innovation Type | Description |
|---|---|
| Self-healing surge protection | Able to repair itself after minor damage, thus extending its lifespan. |
| Nanomaterial application | Uses special materials to improve performance and reduce size. |

People use surge protectors in many places. Home offices need them to protect computers and printers. Living rooms use surge protectors to protect televisions, game consoles, and sound systems. Kitchens use them to protect microwaves and refrigerators. Schools and businesses use surge protectors to protect projectors, servers, and other electronic equipment. Surge protectors are especially important in cases of lightning strikes or line faults. They can prevent power surges at any time. Surge protectors are also used in sensitive environments such as hospitals and data centers. Using a surge protector is a smart way to protect your electronic equipment and ensure its safe operation.
Tip: Be sure to check if your equipment needs a surge protector, especially if the equipment is expensive or difficult to replace.
Power strips and surge protectors work differently. A power strip simply provides more outlets; it does not protect your devices from power surges. A surge protector protects electronic devices from sudden voltage spikes. These voltage spikes can occur during thunderstorms or when large machinery is switched on or off. Surge protectors use special components to block or divert excess current, thus protecting computers, televisions, and other devices.
The table below compares their protection functions:
| Feature | Surge Protector | Power Strip |
|---|---|---|
| Voltage Spike Limiting | Yes | No |
| Transient Overvoltage Protection | Yes | No |
| UL 1449 Compliant | Yes | No |
| Surge Limiting Components | Yes | No |
| Overload Protection Circuit Breaker | Optional | Yes |
Surge protectors adhere to strict safety standards, such as UL 1449. Power strips follow other standards, such as UL 1363. If you want to protect your electronic devices from power surges, use a surge protector.
Power strips and surge protectors may look the same externally, but their internal structures are quite different. Surge protectors contain special components called metal oxide varistors (MOVs). These components absorb and divert excess voltage when a power surge occurs. Surge protectors usually have indicator lights to show whether they are functioning correctly. Power strips do not have these components or indicator lights; they simply provide more outlets.
The table below shows the main internal differences:
| Component Type | Surge Protector | Power Strip |
|---|---|---|
| Voltage Protection | Yes, uses MOV to clamp surges | No protection |
| Indicator Light | Yes, usually labeled ‘Protected’ | Usually none |
This means that only surge protectors can protect your equipment from damage during a power surge.
Surge protectors are typically more expensive than regular power strips. The higher price is due to the special components inside surge protectors. These components help prevent power surges. Regular power strips are less expensive because they lack these safety components. When you buy a surge protector, you’re paying for extra safety protection. For simple appliances like lamps or fans, a regular power strip is sufficient. However, for expensive electronic devices, a surge protector is the best choice.
Note: Spending a little more on a surge protector can protect your devices from damage, saving you money on future repairs.
You can distinguish between regular power strips and surge protectors by a few features. Surge protectors usually have an indicator light that displays “protected.” This indicator shows whether the surge protection function is working correctly. If the light is green, it means the device is protecting your electronics. If the light is red or off, it means the protection function may be malfunctioning. Surge protectors typically have a label indicating compliance with the UL 1449 standard. Regular power strips usually lack these labels or indicator lights.
The following table can help you identify each device:
| Indicator Type | Description |
|---|---|
| Indicator Lights | Surge protectors typically have an indicator light showing the protection status. Green indicates normal operation, while red or off indicates a fault. |
| UL Rating | Surge protectors should have a UL 1449 certification label, and regular power strips should have a UL 1363 certification label. |
Always check these labels before purchasing. This helps you choose the right device for your needs.
