Did you know that using an extension cord can significantly impact a blow dryer’s performance? While extension cords offer convenience by allowing flexibility in where you style your hair, they can also introduce potential risks and limitations. Let’s have a look on how extension cords affect blow dryer performance and what are good practices for choosing the right extension cord.
What Power is needed?
Typically a regular blow dryer consumes between 1,200 to 1,875 watts of power. Hair blow dryer requires a steady and reliable electrical current. Household electrical outlets generally provide 110-120 volts. It is sufficient for most blow dryers. However, when you use an extension cord, it can interfere with the normal power supply and lea to your tool’s performance issues.
How an Extension Cord Affects a Blow Dryer’s Performance
Voltage Drop and Reduced Power
One of the biggest concerns when using an extension cord with a blow dryer is voltage drop. When electricity travels through a long or thin wire, resistance increases, causing the voltage to decrease before it reaches the blow dryer. This can lead to:
- Slower heating times. The heating element in the blow dryer may not reach its full potential, making it less effective at drying hair.
- Reduced airflow power. The motor that powers the fan might not run at optimal speed, leading to weaker airflow and longer drying times.
- Inconsistent heat levels. Voltage fluctuations can cause the heat to be inconsistent, affecting styling results and potentially damaging hair.
Overheating and Fire Hazards
Blow dryers draw a high amount of current, and if the cord is not rated for such power loads, it can overheat. Here is what can happen is the cord overheats:
- Melt its insulation, exposing live wires and increasing the risk of electrical fires.
- Overload the circuit, potentially tripping the breaker or causing damage to the blow dryer.
- Cause damage to the extension cord itself, leading to short circuits or electrical shocks.
Increased Wear on the Blow Dryer
A blow dryer running on an underpowered or unstable electrical supply may have to work harder to compensate for the lower voltage. In such case, you can experience the following issues:
- Faster motor burnout. The motor may wear out more quickly due to inefficient operation.
- Shortened lifespan. Components such as the heating element and fan could deteriorate faster, leading to the need for frequent replacements.
- Unusual noise or vibrations. The motor may struggle to function properly, resulting in a noisy or unstable operation.
Finding Suitable Extension Cord for a Blow Dryer
If you must use an extension cord with your blow dryer, make sure to selecting one that meets high-power requirements and ensures safe operation.
Here is what things you should consider:
Use a Heavy-Duty Extension Cord
Choose an extension cord specifically designed for high-wattage appliances. Look for one labeled “heavy-duty” or “for appliances”, as these are designed to handle high currents without overheating.
Check the Wire Gauge (AWG Rating)
The wire gauge of an extension cord determines its ability to handle power loads. The lower the AWG number, the thicker the wire and the better it can carry high power. For blow dryers, use:
- 14 AWG or lower (12 AWG is ideal). Suitable for high-power appliances.
- Avoid 16 AWG or higher. These are too thin and may cause overheating.
Keep the Cord Length Short
Remember, the longer the extension cord – the greater the voltage drop. To minimize power loss, choose a cord that is 10 feet or shorter.
Look for Safety Features
Select an extension cord with built-in safety features such as:
- Surge protection. Protects the blow dryer from electrical surges.
- Grounded three-prong plug. Ensures better electrical stability and reduces shock risk.
- High-heat resistance. Prevents melting or fire hazards.
Consider a Dedicated Circuit
If you frequently use a blow dryer in areas with limited outlets, consider having a dedicated circuit installed instead of relying on a cord. This will ensure a steady power supply without voltage fluctuations.
Alternatives to Extension Cords for Blow Dryers
If using an extension cord is unavoidable, consider these alternatives:
- Use a power strip with a built-in circuit breaker. This provides better power management and prevents overloading.
- Move closer to an electrical outlet. Reducing the need for an extension cord eliminates potential power loss and overheating risks.
- Use a battery-powered blow dryer. Some new models are designed for portability and don’t require an extension cord at all.
Final Thoughts
Yes, using an extension cord with a blow dryer does sound like a convenient solution. On the other hand, it can have serious consequences for performance, safety, and appliance longevity. Indeed, blow dryer’s functionality can be affected by voltage drops, overheating risks, and electrical inefficiencies. A heavy-duty, low-gauge, short-length cord with proper safety features will for sure reduce potential risks.
By understanding how extension cords affect blow dryers you can get optimal performance, safety, and long-term durability of your hairstyling tool.
