What Is a Power Strip? Uses, Types, Safety Tips & Buying Guide

Written by

A power strip is a device that lets you plug multiple electrical devices into one wall outlet. It is commonly used in homes, offices, dorm rooms, entertainment centers, workshops, and charging stations when one outlet is not enough.

A compact example is the LINKVOLT 6-Outlet Surge Protector with 2 USB-A Ports. It plugs directly into a grounded wall receptacle and adds six AC outlets, two USB-A charging ports, 1200-joule surge protection, three rotating outlets for bulky plugs, and protection-status indicators. Its total electrical rating is up to 15A/1875W for compatible indoor devices.

What Is a Power Strip

A power strip consists of multiple electrical sockets connected to a flexible power cord that plugs into a wall receptacle, allowing several devices to receive power from a single outlet.

Power strips come in a variety of designs, from compact plastic units to larger metal-housed models with multiple outlets. Many feature illuminated switches that show when power is active, while some include built-in safety mechanisms such as resettable circuit breakers or push-button protection that automatically disconnects power if the unit overheats.

How Does a Power Strip Work

A power strip works by distributing electricity from one wall outlet to multiple receptacles on the strip.

When you plug the power strip into the wall, power flows through the cord and internal conductors to each outlet on the strip. Devices plugged into the power strip draw electricity through that same connection.

Some power strips include extra safety or convenience features, such as:

  • On/off switch
  • Circuit breaker
  • Surge protection
  • Protected indicator light
  • Grounded indicator light
  • USB-A ports
  • USB-C ports
  • USB-C PD charging
  • Flat or low-profile plug
  • Wall-mounting holes
  • Wide-spaced outlets for bulky adapters

Is a Power Strip the Same as a Surge Protector?

No. A power strip and a surge protector may look similar, but they are not always the same.

A basic power strip gives you more outlets.

A surge protector gives you more outlets and helps protect connected electronics from voltage spikes.

To know whether a power strip is also a surge protector, look for terms such as:

  • Surge protector
  • Surge protection
  • Joule rating
  • Protected indicator
  • Grounded indicator
  • Clamping voltage

Common Types of Power Strips

Power strips come in several styles. The right one depends on your space, devices, and protection needs.

Basic Power Strip

A basic power strip provides several AC outlets. It may include an on/off switch or breaker, but it may not include surge protection.

Best for:

  • Lamps
  • Small fans
  • Chargers
  • Low-power accessories
  • Temporary indoor setups

Surge Protector Power Strip

A surge protector power strip adds surge protection to help protect electronics from voltage spikes.

USB Power Strip

A USB power strip includes AC outlets plus USB charging ports. This reduces the need for multiple charging bricks.

USB-C PD Power Strip

A USB-C PD power strip supports USB-C Power Delivery, which can charge compatible phones, tablets, and some smaller laptops faster than older USB ports.

What Should You Not Plug Into a Power Strip?

Power strips are not designed for every device. High-wattage appliances should usually be plugged directly into a wall outlet.

Avoid plugging these into a standard power strip:

  • Space heaters
  • Microwaves
  • Refrigerators
  • Air conditioners
  • Toaster ovens
  • These devices can draw more power than a power strip is designed to handle, increasing the risk of overheating or tripping a breaker.

A power strip gives you more outlets, but it does not give you more electrical capacity.

How to Choose the Right Power Strip

Choosing a power strip is not just about the number of outlets. Consider your devices, space, and safety needs.

1. Decide Whether You Need Surge Protection

If you are plugging in electronics such as a TV, computer, router, gaming console, or monitor, choose a surge protector power strip.

2. Check the Joule Rating

For surge protector power strips, the joule rating tells you how much surge energy the product can absorb.

3. Count the Outlets You Need

Choose enough outlets for your devices so you do not need to daisy-chain another strip.

4. Look for USB-A or USB-C Charging

If you charge phones, tablets, earbuds, or accessories, choose a model with USB ports.

5. Consider the Plug Shape

A low-profile or flat plug can fit better behind furniture, desks, or entertainment centers.

6. Choose the Right Cord Length

A longer built-in cord is safer than plugging the strip into an extension cord.

7. Check the Electrical Rating

Look at the amp and watt rating. Common household power strips are often rated around 15A and 125V, but always check the product label.

8. Look for Certification

Choose products with recognized safety certification such as UL or ETL.

Conclusion

A power strip is a simple but useful device that turns one wall outlet into multiple outlets. It is commonly used for desks, bedrooms, entertainment centers, dorm rooms, and charging stations.

However, not every power strip is a surge protector. If you are powering sensitive electronics such as TVs, computers, routers, gaming consoles, or monitors, choose a surge protector power strip instead of a basic strip.
