Can I Plug a Hair Dryer Into an Extension Cord? A Safety Guide

If your hair dryer’s power cord is just a little too short to comfortably reach the outlet, you may wonder – can I safely use an extension cord instead?

Most experts advise against plugging high-power electrical devices like hair dryers into extension cords or power strips. But in reality, there are times you may have no other option.

The good news is that with the right precautions, you can use an extension cord with a hair dryer without risks. In this comprehensive guide, we’ll cover everything you need to know to do it safely.

Are Extension Cords Safe for Hair Dryers?

The main concern with using extension cords for hair dryers is fire risk. Hair dryers draw a lot of power and generate heat. Plugging them into undersized, poor quality extension cords can potentially lead to:

• Overloaded, overheated cords
• Melted insulation
• Exposed wires
• Electrical fires

However, there are ways to minimize risks when using an extension cord with a hair dryer:

• Choose a heavy duty, adequate gauge cord
• Don’t exceed length limits
• Inspect for damage regularly
• Avoid cheap, thin cords
• Don’t daisy chain multiple cords

While not ideal, with proper precautions a quality extension cord can safely be used with a hair dryer when necessary.

Extension Cord Size for Hair Dryers

The key factor in safely using an extension cord with a hair dryer is selecting the right gauge cord for the power needs. Gauge refers to the thickness of the internal wires – thicker wires can handle more power.

Match the Amperage Rating

• Check the amps (amps) or wattage your hair dryer requires. This is usually indicated on a label on the dryer.

• Choose an extension cord with an equal or higher amp rating. This ensures the cord can handle the electrical load.

For most hair dryers that pull 10-15 amps, a heavy duty 14 gauge extension cord rated for 15 amps is sufficient. More powerful dryers may need a 12 gauge cord.

Gauge Guide

• 16 gauge: Only for light loads like lamps, phone chargers. Not hair dryers.

• 14 gauge: For medium loads like hair dryers under 1500-1800 watts.

• 12 gauge: For high loads like 1875-2000+ watt hair dryers.

• 10 gauge: For extra high loads over 2000W.

Extension Cord Length Limits

The longer an extension cord is, the more power it loses along the way from resistance. A longer cord also generates more heat.

To maintain safety, keep extension cords under these maximum lengths:

• 16 gauge: Under 25 feet
• 14 gauge: Under 50 feet
• 12 gauge: Under 100 feet
• 10 gauge: Over 100 feet

Try to use the shortest, thickest cord possible for your needs. Never exceed the recommended limits.

Other Extension Cord Safety Tips

In addition to correct gauge and length, follow these tips for safely using extension cords with hair dryers:

• Fully unwind cords to prevent overheating.

• No daisy chaining: Never connect multiple extension cords.

• Indoor use only: Don’t run cords outdoors/through windows.

• No permanent use: Extension cords are temporary solutions.

• Proper outlet: Plug cord into a GFCI outlet with the proper amperage.

• Replace damaged cords: Don’t use cords with damaged plugs or exposed wires.

• Secure the cord: Don’t let it hang where it can be tripped over and unplugged.

• Unplug when not in use: Don’t leave plugged in unsupervised.

• Avoid cheap cords: Invest in a heavy-duty, UL-certified cord from a reputable brand.

Recommended Extension Cords for Hair Dryers

These top-rated extension cords are recommended for safely using with hair dryers:

• Twine 12FT Heavy Duty Extension Cord – 12 gauge, 1875W, 15 amps

• Holiday Living 25 Foot Extension Cord – 14 gauge, 15 amp, UL-listed

• Conntek Extension Cord – 14AWG, 15 amp, 150V, yellow jacket

• Amazon Basics Extension Cord – 14 gauge, 15A, UL-certified

• ** Woods Outdoor Extension Cord** – 10 gauge, 50 feet, all-weather

Carefully compare your hair dryer’s wattage and amp rating against the extension cord specs to ensure a proper match. Invest in a quality cord from a trusted brand for safety.

Are Power Strips Safe for Hair Dryers?

Power strips or surge protectors should not be used with high-draw electrical devices either according to safety standards. The fire concerns are similar to extension cords regarding overheating and overloaded circuits.

However, modern heavy duty power strips that specifically indicate they are rated for high-power devices like hair dryers can provide a safer alternative when an extension cord isn’t available.

Features to look for include:

• 15 amp power rating

• 1875 watts (or higher)

• Built-in circuit breaker

• Indicator lights

• Heavy 14+ gauge wire

• UL-certified

Always check your hair dryer wattage against the power strip rating to ensure it can handle the load. Never plug high-wattage devices like dryers into cheap, regular power strips.

The Bottom Line

While not considered ideal, you can safely use an extension cord or power strip with your hair dryer as long as you follow important safety guidelines. This includes matching the proper cord gauge thickness and length to your dryer’s wattage needs.

Invest in a heavy-duty, UL-rated cord from a reputable brand, and be diligent to inspect for any damage regularly with use. With the right cord and safe usage practices, an extension cord can provide the quick fix you need to give your dryer some extra reach.
