Can You Plug an Extension Cord into a Power Strip?

We’ve all been there: you have numerous devices and appliances that need power sources, but your home or office lacks the appropriate number of outlets to run everything at once. You might be tempted to get creative with your available resources and plug an extension cord into a power strip in order to meet your needs. However, this can have disastrous effects. 

When you daisy chain these supplementary power cables, you risk dangerous electrical fires and irreversible damage to your devices. Today, we’ll discuss the many dangers of piggybacking extension cords and power strips and explain why it’s safer to find another option. 

What’s the purpose of an extension cord?

An extension cord is a cable used to power devices that aren’t in close proximity to an outlet, but they’re not a permanent solution for long-term electrical needs. Here’s a detailed look at when, why, and how to use an extension cord: 

Functionality

Extension cords bridge the gap between certain devices and the nearest available wall outlet. They’re not intended to power appliances that use a lot of electricity or those with heating elements, so never plug a clothes dryer, oven, or dishwasher into one of these cables. Even smaller appliances like toasters and air fryers should be plugged directly into the wall. 

So, which devices are safe to plug into an extension cord? It’s fine to use electronics like computers, lamps, and radios with these extenders as long as they don’t exceed the joule rating on your particular cable. 

Temporary use

Over time, consistent use and exposure to the elements can quickly degrade the insulation protecting the interior components of your extension cords. After all, they’re only made to function on a temporary, short-term basis, not continually. 

Choosing the right cord

When you purchase an extension cord, the label should clearly state the amperage, gauge, and plug type. Compare these figures with the specifications of the device you’ll use it with. Additionally, be sure you buy one that’s long enough to cover the necessary distance without excessive slack, as extra length can reduce the available voltage. 

What does a power strip do?

A power strip is a device that sends electricity from a single wall outlet to multiple outlets located on a receptacle at the end of a cable. Unlike extension cords, power strips can be used for long-term energy needs. 

Saves energy

Many power strips on the market today include sensors that detect when a device is off and cut power to that connection. In turn, you’ll use less “standby” energy or electricity that typically flows to devices that aren’t in use. 

Protects against power surges

Power strips typically include a surge protector to fortify your devices against electrical fluctuations. When your home experiences a power surge, the strip will automatically turn off to minimize damage to connected devices. 

Prevents circuit overload

Another feature of modern power strips is their ability to prevent an overloaded electrical circuit. When you connect too many devices to your strip, it cuts the electrical current to safeguard against short circuits that can fry your electronics.

Is it okay to plug an extension cord into a power strip?

The answer to this question is no. It is never safe to plug an extension cord into a power strip. Here are a few reasons why: 

Can cause overloading

Both power strips and extension cords are built to handle a certain amount of power at any given time. When joined together, you increase the risk of major complications and compliance issues. According to the Occupational Safety and Health Administration (OSHA), the law surrounding the use of these devices prohibits daisy chaining in all forms. 

Product warranties and insurance will not cover the cost of repairs, damage, or burns caused by improperly used extension cords and power strips, and manufacturers can’t be held responsible. 

Could lead to electrical fires

When multiple power strips and extension cords are connected to a single outlet, there’s a significant risk of burns and electrical fires. Placing excessive loads on one receptacle throws off the balance of your electrical circuit and puts you in danger. This may be especially true of multiple cords that include an adapter. 

Can cause damage to electrical devices

While most modern power strips contain surge protectors, you can’t rely on these internal components to safeguard expensive devices. These built-in mechanisms may limit potential damage, but they can’t always protect against substantial power surges. Pulling more electricity to these strips increases the chances of power surges that could fry your laptop.
