Why Does My Power Strip Keep Turning Off? A Comprehensive Guide

Dealing with a power strip that unexpectedly turns off can disrupt your day and raise concerns about the safety of your electrical devices. If you find yourself asking, "Why does my power strip keep turning off?", it's important to get to the root of the problem. This guide will explore the typical issues that lead to power strip shutdowns, walk you through a comprehensive diagnostic process, and share key practices for using power strips safely. Read on to ensure that your power supply is both reliable and secure, keeping your devices running smoothly without any unwanted interruptions.

Common Problems That Lead to Power Strip Shutdowns

Let’s discover the typical issues that can cause your power strip to unexpectedly shut down.

  • Overloading

One of the most common causes of power strip shutdowns is overloading. When too many high-wattage devices are plugged into a single strip, the capacity can exceed the strip's. As a safety measure, the circuit breaker within the strip trips.

  • Short Circuits

Faulty wiring or damaged devices can cause short circuits. When a short circuit occurs, the power strip shuts off to prevent potential electrical fires or damage to your devices. Regular inspection of your devices and cords can help mitigate this risk.

  • Surge Protection Activation

Many modern power strips come with built-in surge protection. During a power surge, the strip's internal mechanisms activate to protect connected devices, often shutting off the power strip. This feature is crucial for safeguarding electronics.

  • Faulty Power Strip

Sometimes the problem lies within the power strip itself. Aged or defective power strips can malfunction, leading to random shutdowns. It's important to replace power strips that show signs of wear or have been used for many years.

  • Environmental Factors

External factors such as excessive heat, moisture, or dust can impact a power strip's performance. These elements can cause internal components to overheat or short out, leading to shutdowns.

Step-by-Step Guide to Diagnosing Your Power Strip Issues

Now that we've explored the typical problems causing power strip shutdowns, let's walk through how to diagnose these issues with your power strip step by step.

  1. Check for Overloading

Unplug all devices from the power strip and plug them back in individually. Monitor if the strip shuts off when a particular device is connected. This helps identify if a specific device is causing the overload.

  1. Inspect for Damaged Cords

Examine all connected device cords and the power strip's cord for any visible signs of damage such as fraying or exposed wires. Replace any damaged cords immediately.

  1. Test with Another Outlet

Try plugging the power strip into a different wall outlet, preferably on a different circuit, to determine if the issue lies with the original outlet. This can help identify whether the problem is with the power strip or the electrical wiring in your home.

  1. Reset the Power Strip

If your power strip has a reset button, press it to reset the strip's internal circuit breaker. If the power strip operates normally after this, the issue might have been due to a temporary overload or power surge. Frequent resets, however, could indicate a more serious issue.

  1. Use a Multimeter

Test the power strip for continuity and proper voltage output if you can access a multimeter. This can help identify internal faults within the strip.

  1. Check Environmental Conditions

Ensure the power strip is placed in a dry, cool, and dust-free environment. Avoid exposing the strip to direct sunlight, high humidity, and excessive dust, as these conditions can cause overheating or other issues.

  1. Replace the Power Strip

If none of the above steps resolves the issue, it may be time to replace the power strip. Look for a new one with features that suit your needs, such as a sufficient number of outlets, surge protection, and safety certifications from recognized standards bodies like UL or CE.

For those needing a reliable solution to manage multiple devices safely, the Anker 351 Power Strip presents an ideal option. This power strip is designed to cater to all your power needs effectively, featuring 12 AC outlets and multiple USB ports, including a fast-charging 20W USB-C port. It stands out with an 8-point safety system that encompasses surge protection and temperature control, ensuring the highest safety standards. The thoughtful layout with spaced outlets accommodates larger plugs, making it a smart choice for both home and office environments.

How to Use Power Strips Safely?

Using power strips safely is crucial to prevent shutdowns and ensure the longevity of both the strip and connected devices. Here are some essential tips for safe usage:

  • Understand the Power Rating. Always check the power strip's wattage rating and that the combined wattage of all connected devices does not exceed this limit. Overloading the strip can lead to shutdowns and potential fire hazards.
  • Use Surge Protectors. Opt for power strips with built-in surge protection. These strips provide an extra layer of safety by protecting your devices from voltage spikes and surges.
  • Avoid Daisy Chaining. Never plug one power strip into another. This practice, daisy chaining, can significantly increase the risk of overloading and cause both strips to shut down.
  • Regular Inspections. Periodically inspect your power strip for signs of wear and tear. Replace it if you notice frayed cords, loose connections, or other damage.
  • Proper Placement. Keep your power strip in a well-ventilated area away from heat sources and moisture. Place it on a flat, stable surface to prevent accidental tipping or disconnection.
  • Turn Off When Not in Use. If you are not using the devices connected to the power strip, turn off the strip to conserve energy and reduce the risk of overheating.
  • Avoid High-Wattage Appliances. Due to their high power consumption, avoid using power strips for high-wattage appliances such as microwaves, space heaters, or refrigerators. Instead, plug these appliances directly into wall outlets.

Following these safety guidelines will help you make the most out of your power strips while minimizing potential risks. When choosing a power strip, consider reputable brands like Anker. Anker power strips are designed with high-quality materials and incorporate advanced safety features such as surge protection and durable casings. Their products ensure reliable power distribution and enhanced protection for all your devices, making them an excellent choice for both home and office use.


In conclusion, understanding "why does my power strip keep turning off" not only protects your devices but also ensures electrical safety. From diagnosing common issues to adhering to safe usage practices, taking the right steps can mitigate shutdowns and extend the lifespan of your power strip. If you're experiencing frequent issues, consider upgrading to a reliable Anker power strip, known for its superior safety features and durability. Try Anker today and experience the peace of mind that comes with using high-quality, dependable products. 


Is There a Reset Function When a Power Strip Turns Off?

Many power strips are equipped with a reset function, typically a circuit breaker or reset button, that activates when the strip turns off due to an overload or short circuit. This function allows the power strip to be reset and used again once the underlying issue causing the shutdown has been addressed.

Can an Overloaded Power Strip Cause It To Turn Off?

Yes, an overloaded power strip can cause it to turn off. Power strips have built-in circuit breakers that detect excessive current flow, which can occur when too many devices are connected and drawing power simultaneously. This safety mechanism prevents potential damage or fire hazards by automatically shutting off the power.

What Should I Do When My Power Strip Turns Off and Won’t Turn Back On?

If your power strip turns off and won’t turn back on, first unplug all devices and attempt to reset the strip using its built-in reset button or switch. If it does not reset, check for any visible damage or signs of burning. If the strip still fails to function or shows damage, it should be replaced to ensure safety and proper functionality.
