Can You Plug a Power Strip into a Power Strip? Exploring Safety & Alternatives

Can You Plug a Power Strip into a Power Strip? Exploring Safety & Alternatives

When it comes to increasing the number or reach of electrical outlets in your home or office, you might be tempted to just connect one power strip to another. But can you plug a power strip into a power strip? While this method might seem convenient, it is important to understand the safety implications it entails.

This guide delves into whether it's safe to connect two power strips, offers guidelines on safe usage of power strips in your living or working space, and explores alternative methods to extend your power capacity without compromising safety. Join us and learn to power multiple electronics safely and efficiently.

Is It Safe to Connect Two Power Strips?

Connecting two power strips together, a practice commonly known as "daisy chaining," is generally considered unsafe and advised against by electrical safety experts. Although it might seem like a convenient way to extend the reach or add the number of electrical outlets, it's important to understand the risks involved.

The primary concern with connecting power strips together is the risk of overloading the devices. Each power strip is designed to handle a specific electrical load, and by chaining them, you potentially exceed the total power load that the first strip can handle safely. This can lead to overheating and might even result in fire hazards.

Secondly, daisy chaining power strips can lead to circuit overload. Most residential and office circuits are designed to handle a defined maximum amount of current. Connecting multiple power strips can draw more power than the circuit can handle, leading to tripped breakers or even more dangerous electrical incidents.

Electrical standards and safety organizations like the U.S. Consumer Product Safety Commission and the National Electrical Code strongly advise against daisy chaining power strips. They recommend that each power strip be plugged directly into a wall outlet to ensure that safety mechanisms function correctly.

How to Use Power Strips Safely in Your Home?

Ensuring the safe use of power strips in your home is crucial for preventing electrical hazards and protecting your devices. Here are some essential tips on how to use power strips safely:

  • Choose Quality Power Strips:Not all power strips are created equal. Invest in quality power strips from reputable brands with built-in safety features to ensure reliability and durability. The Anker 615 USB Power Strip (GaNPrime 65W), for instance, utilizes ActiveShield 2.0 technology, which conducts temperature checks three million times daily to prevent overheating.

It also incorporates the latest GaN technology for enhanced safety and a comprehensive 7-point safety system. This system includes a fire-resistant casing, internal safety shutters, short-circuit protection, grounded protection, and more, providing reliable power with added peace of mind.

  • Check the Load Capacity:Each power strip is rated for a specific electrical load, usually denoted in watts or amps. Make sure the combined load of all devices plugged into the strip does not exceed this rating to prevent overheating and potential fires.
  • Avoid Daisy Chaining:As mentioned, connecting multiple power strips together, known as daisy chaining, is a dangerous practice and should be avoided. It significantly increases the risk of overloading the circuit and causing a fire.
  • Mind the Placement:Avoid placing power strips in enclosed spaces or areas with poor ventilation. Heat can build up around the strip, increasing the risk of overheating. Also, keep power strips away from water sources like sinks or tubs. Moisture can cause short circuits and other electrical hazards.
  • Regular Inspection:Periodically check your power strips for signs of damage, such as frayed wires, loose connections, or scorch marks. Discontinue use immediately if any damage is evident.
  • Use Surge Protectors:For added safety, consider using surge protectors instead of basic power strips, especially for sensitive electronics. Surge protectors help shield your devices from sudden spikes in voltage, providing an additional layer of safety.

Alternative Ways to Extend Your Power Strips without Safety Concerns

To safely manage and extend your electrical capacity at home without resorting to unsafe practices like daisy chaining power strips, consider these alternative approaches:

  • Upgrade to a Higher Capacity Power Strip:Opt for a power strip with more outlets and a higher electrical load capacity. This allows you to plug in more devices safely without exceeding safety limits.
  • Use a Quality Extension Cord:If distance is the issue, use a high-quality, heavy-duty extension cord that can handle the required load. Ensure that the extension cord is rated for the appliances or electronics you intend to connect and directly plug it into a wall outlet.
  • Install Additional Wall Outlets:For a more permanent solution, consider having additional wall outlets installed where you most need them. This can be especially useful in older homes that may not have enough outlets to meet modern electrical demands. Hiring a qualified electrician to install new outlets is a safe and effective way to enhance your home's electrical infrastructure.
  • Install Dedicated Circuits:For appliances that require a lot of power, like home air conditioners or washers and dryers, installing dedicated circuits can prevent overloads. This means these appliances won't share a circuit with other devices, which can reduce the risk of tripping breakers or potential electrical fires.


So, can you plug a power strip into a power strip? As we've learned, connecting one power strip to another may offer a temporary fix, but it's not a recommended solution due to potential safety hazards and the risk of overloading circuits. Instead, employing alternative methods such as upgrading to a power strip with more outlets or installing additional wall outlets can enhance safety and efficiency. By understanding the risks and exploring safer alternatives and practices, you can ensure that your approach to managing multiple electronic devices is both practical and prudent.


Is it against electrical codes to plug a power strip into another power strip?

Yes, it is generally against electrical codes to plug a power strip into another power strip. This practice, known as "daisy chaining," can lead to overloading and overheating, which are major fire hazards. Most fire safety guidelines and electrical codes recommend against this to ensure safety and prevent potential electrical accidents.

Can daisy chaining power strips void equipment warranties?

Yes, daisy chaining power strips can void equipment warranties. Many manufacturers specify that their products must be plugged directly into a wall outlet or used in accordance with all local electrical codes. These electrical codes typically advise against daisy chaining power strips due to increased risks of overloading, electrical fires, or equipment failure. If damage occurs under such conditions, warranties may not cover the repairs or replacements.

Is it a fire hazard to plug a power strip into a power strip?

Yes, it can cause a fire hazard to plug a power strip into another power strip, often referred to as "daisy chaining." This practice can overload the circuit, potentially leading to overheating and causing a fire. It's important to connect power strips directly to a wall outlet to ensure electrical safety.
