Buying Guide for Selecting Power Strips for Space Heaters
When choosing a power strip for a space heater, consider these essential factors to ensure safe and reliable performance:
Power Rating and Capacity
Space heaters typically draw between 1000 to 1500 watts. Always select a power strip that supports at least 15 amps and 1875 watts to handle peak loads safely. For higher demand or multiple devices, consider 20 amp rated power strips. Avoid using strips rated lower than your heater’s wattage to prevent overheating or electrical hazards.
Surge Protection
Surge protection is critical to prevent damage from power spikes. Look for power strips with surge protection joule ratings above 1000 joules. A higher joule rating means better protection, especially in areas prone to electrical fluctuations. Surge protectors also often have circuit breakers or auto shut-off features for additional safety.
Outlet Spacing and Quantity
Heaters often come with bulky plugs or adapters; therefore, make sure the power strip has wide spaced outlets (generally at least 1.5 inches apart or more) to avoid blocking adjacent sockets. Pick outlets count based on your need—more outlets for multiple devices but ensure the total power draw is within the strip’s rating.
Build Quality and Materials
Heavy-duty metal or thick aluminum housing increases durability and heat resistance. Avoid cheap plastic enclosures that can crack or melt. Also, consider power strips with reinforced cords of gauge 14 AWG or thicker for improved safety and longevity.
Cord Length and Plug Type
Cord length determines placement flexibility. Standard lengths range from 3 to 15 feet—choose based on your room layout. A right-angle or flat plug option can help fit in tight spaces or behind furniture without bending the cable, reducing wear and tear.
Mounting Options
Power strips with screw holes or mounting brackets allow secure installation on walls or workbenches, reducing clutter and keeping cords organized. This is particularly useful in workshop or garage setups with space heaters.
Certifications and Safety Features
Look for UL or ETL certifications ensuring compliance with safety standards. Circuit breakers, overload protection, and resettable switches provide peace of mind when running high wattage devices like space heaters.
By carefully considering power rating, surge protection, build quality, and safety features, you can choose a power strip that reliably supports your space heater while minimizing risks.
