Is It Safe to Leave Power Strips Plugged in All the Time?

Sometimes I forget the power strip even exists—tucked behind my desk, always on. But is leaving it plugged in 24/7 really safe?

Leaving a power strip plugged in all the time is generally safe if it’s high quality, not overloaded, and used in a well-ventilated area. However, aging strips, poor ventilation, or proximity to flammable materials can pose fire risks. Experts recommend unplugging when not in use for added safety, especially in homes with children or pets.

We use power strips¹ everywhere—but few of us stop to think if it’s okay to leave them running all the time.

Potential Fire Hazards: What the Experts Say

Fire safety professionals are clear: not all power strips¹ are created equal.

Old, overloaded, or poorly made power strips¹ can overheat and spark fires—especially when left plugged in around the clock.

Overheating and Electrical Fires

Fire departments report that many home fires start from improper power strip use. Heat builds up from overloading or dust accumulation, especially behind furniture. When placed near curtains or in tight spaces, a small spark can escalate quickly.

Age and Wear Are Hidden Dangers

Worn-out internal wiring or damaged insulation can silently fail over time. Strips over five years old—especially ones without surge protection²—should be replaced. Look for cracks, discoloration, or buzzing sounds, which may indicate danger.

Energy Consumption When Not in Use: Standby Power Explained

Power strips can quietly add to your energy bill.

Even when your devices are off, plugged-in power strips¹ can draw “phantom” electricity—wasting energy and money.

Standby Power: A Hidden Cost

According to the U.S. Department of Energy, standby power can account for 5–10% of household electricity use. That means even your “off” printer or TV could still be draining power.

Smart Strips Can Cut the Waste

Some modern power strips¹ detect when devices aren’t in use and cut power automatically. These are ideal for TV centers, computer desks, and even gaming setups.

When Is It Safe—and When Is It Not? Situational Guidelines

Context matters when deciding whether to keep a power strip always on.

If the strip is newer, has overload protection³, and isn’t overloaded, it’s typically safe. But in certain settings—like near water or unattended for long periods—it’s best to unplug.

Use Cases: Green Light vs. Red Flag

Safe Situations:

• Surge-protected strip powering a desktop
• Strip placed in open air (not under rugs)
• Smart strip with auto-shutoff⁴

Unwise Situations:

• Plugging in space heaters or hair dryers
• Behind couches or under beds
• Wet or humid environments (bathroom/kitchen)

Simple Safety Checks

• Is your strip warm to the touch?
• Do plugs fit loosely or spark?
• Is there visible damage on the housing?

If yes, it’s time to unplug and replace.

Smart Alternatives: Auto-Shutoff and Timer Power Strips

For those of us who always forget to turn things off (guilty), smart power strips⁵s](https://www.cnet.com/home/kitchen-and-household/best-surge-protector/)[^1] offer a better solution.

Smart strips with auto-shutoff⁴, timers, or app control can reduce risk and save money. They’re ideal for tech-heavy homes and offices.

Modern Features That Protect and Empower

Smart strips today go beyond just “on/off”:

• Auto-shutoff: Turns off when a device idles
• Wi-Fi control: Schedule usage via mobile app
• Voice assistants: Alexa and Google-compatible models available
• Overload alerts: Some models send a notification to your phone

Choosing the Right Smart Strip

Look for CE, RoHS, or UL certification. Reliable brands include Belkin, TP-Link (Kasa), and How-dy’s own OEM options—built for safety-conscious buyers in Europe and beyond.

Conclusion

Leaving your power strip plugged in isn’t always dangerous—but it’s not always safe either. If in doubt, unplug, upgrade, or go smart. Your devices—and your peace of mind—are worth it.
