Can You Plug a Heated Blanket into a Power Strip: Safety Tips

As the winter chill sets in, reaching for a heated blanket becomes second nature. But in modern homes bustling with devices, finding an available outlet can be a challenge. Many turn to power strips as a convenient solution.

However, is it safe to plug your heated blanket into one? This guide delves into safety precautions and best practices for using heated blankets with power strips.

Can I Plug a Heated Blanket into a Power Strip?

Plugging a heated blanket into a power strip is a common practice due to convenience, especially in areas where wall outlets are scarce. However, this practice involves significant safety considerations that must be understood to avoid potential hazards.

Understanding the Electrical Load

Heated blankets, like many other heating devices, draw a considerable amount of electricity. Depending on the make and model, a heated blanket can use anywhere from 50 to 200 watts.

Power strips, designed to handle multiple devices, might not always be equipped to manage the high wattage and prolonged use associated with heated blankets. This can lead to several risks:

1. Overloading: Power strips have a maximum wattage rating, and exceeding this limit with multiple devices, including a high-wattage heated blanket, can cause the strip to overload. This overload can trip circuit breakers, damage electrical components, or even cause a fire.

2. Heat Accumulation: Power strips themselves generate heat when in use, especially when multiple outlets are in operation. Adding a heated blanket increases the heat output, which can compound the heat generated by the strip. Excessive heat buildup without adequate dissipation can lead to melting of the power strip’s internal components or the insulation of the cords, presenting a serious fire hazard.

Safety Precautions

To safely use a heated blanket with a power strip, follow these guidelines:

• Check the Rating: Ensure the power strip can handle the wattage of the heated blanket plus any other devices plugged into it. Opt for power strips with higher ratings and built-in circuit breakers for added safety.

• Direct Connection Preferred: Whenever possible, plug the heated blanket directly into a wall outlet. This direct connection avoids the intermediary link of a power strip and reduces the risk of electrical issues.

• Quality Power Strips: If a power strip is necessary, use one that is of high quality and certified by recognized testing laboratories. Features like surge protection and overload protection are critical.

• Monitor Regularly: Keep an eye on the power strip and the heated blanket when in use. Check for any signs of excessive heat, burning smells, or discoloration. These signs could indicate that the power strip or blanket is failing and should be turned off immediately.

• Avoid Daisy-Chaining: Never plug a power strip into another extension cord or power strip (a practice known as daisy-chaining) when using a heated blanket. This increases the risk of overloading and is generally considered unsafe.

Alternatives to Using Power Strips

• Extension Cords: If additional reach is needed, use a heavy-duty extension cord that can handle the wattage of the heated blanket. Ensure that the cord is fully unraveled to avoid coiling, which can also lead to heat buildup.

• Additional Outlets: Consider installing more wall outlets where you frequently use electrical devices. This long-term solution can provide a safer and more convenient power source for devices like heated blankets.

The Risks of Improper Use of Heated Blankets

Using heated blankets improperly can expose users to several significant risks. It is essential to understand these risks to prevent potential accidents:

1. Overheating and Fires: Heated blankets that are left on high settings for extended periods, especially when folded or bunched up, can overheat. This excessive heat might ignite the blanket itself or other flammable materials nearby.

2. Electrical Hazards: Frayed cords, loose connections, or damaged controllers can lead to short circuits or electric shocks. These electrical faults are more likely if the blanket is not regularly inspected or if it’s old.

3. Burns: Prolonged contact with high settings can cause burns, particularly for users with sensitive skin or those who might not feel the heat properly, such as the elderly or those with certain medical conditions.

4. Damage to the Blanket: Improper handling, like folding the blanket tightly or placing heavy objects on it, can damage the internal wiring, leading to malfunctions and reducing the blanket’s lifespan.

Selecting the Right Power Strip for Your Heated Blanket

Choosing an appropriate power strip for use with a heated blanket is crucial to ensure safety and functionality. Here are key features to look for:

1. Wattage Capacity: Check that the power strip can handle the wattage of the heated blanket plus any other devices connected to it. A good rule of thumb is to choose a power strip that can handle at least 20% more power than you plan to draw.

2. Safety Features: Look for power strips with built-in surge protection and circuit breakers. These features help protect against potential overloads and power surges that could cause damage or fire.

3. Quality and Certification: Opt for a power strip from a reputable brand and check for certifications from recognized safety standards organizations, such as UL or ETL. This ensures the power strip meets stringent safety requirements.

4. Number of Outlets and Spacing: Ensure the power strip has enough outlets to meet your needs and that the outlets are spaced widely enough to accommodate larger plugs or adapters without blocking adjacent outlets.

Best Practices for Heated Blanket Safety

To maximize safety when using a heated blanket, follow these best practices:

1. Read and Follow Manufacturer Instructions: Always read the user manual for specific safety and operational guidelines. Follow these instructions carefully to ensure safe use.

2. Regular Inspections: Before each use, inspect the blanket for any signs of wear, such as fraying wires, scorch marks, or exposed elements. Also, check that all connections are secure.

3. Avoid Leaving the Blanket Unattended: Never leave a heated blanket on while unattended or while sleeping, unless it has an auto-shutoff feature. Even then, it’s safer to turn it off when not actively using it.

4. Proper Storage: When not in use, store the blanket flat or loosely rolled in a dry place. Avoid folding it sharply, which could damage the internal wiring.

5. Keep the Blanket Dry: Never use the blanket if it is wet, and do not dry it by plugging it in. Let it air dry completely after washing (if washable) before use.

Conclusion

While plugging a heated blanket into a power strip is generally not advised, understanding the reasons and adhering to safety guidelines can help mitigate risks. Always prioritize direct connection to wall outlets and ensure any power strip used is suitable for high-wattage appliances.
