Buying Guide – How to Choose the Best High Wattage Power Strip
Selecting the right power strip requires evaluating specific technical factors to ensure safety and performance for your unique electrical needs.
Wattage and Amp Capacity
Ensure the strip supports your devices total wattage without exceeding its rated limit. High wattage models often feature 20 amp capacity for industrial tools while standard ones support 15 amps.
Always check the maximum wattage rating to prevent overheating or tripping when running heavy appliances.
Surge Protection Rating
Surge protection is measured in joules with higher values offering better defense against power spikes. Look for at least 2000 joules for general use and 4000 for sensitive equipment.
Higher joule ratings provide stronger protection for valuable electronics during electrical storms.
Outlets and USB Ports
Count the number of AC outlets and ensure they are spaced to fit large adapters. USB ports add convenience but check their total output to avoid slow charging speeds.
Choose outlets and USB ports based on your devices to avoid cable clutter.
Cord Length and Gauge
A 12 gauge cord is essential for high wattage strips to ensure safe power delivery over distance. Cord length should reach your power source without strain but not create tripping hazards.
A thicker 12 gauge cord prevents overheating during high power usage.
Safety Certifications
Look for ETL or UL safety certifications which confirm the product meets strict electrical safety standards. These organizations test for fire resistance and proper insulation.
Certifications ensure the strip has passed rigorous independent safety testing.
Build Material
Metal housings offer better durability and heat dissipation for workshop environments compared to plastic. Ensure the casing is fire resistant and impact resistant for safety.
Metal housing provides better protection and heat management than plastic.
Circuit Breakers
A built-in circuit breaker automatically cuts power during overloads to prevent electrical hazards. Some models offer individual switches for each outlet giving you more control.
Circuit breakers protect against fires by stopping current flow during overloads.
Wall Mountability
Wall mountable designs help save space and keep floors clear in workshops or offices. Check if mounting hardware is included before purchasing.
Wall mounts keep cords organized and prevent tripping hazards.
How to Use and Care for Your High Wattage Power Strip
Always connect the strip to a properly grounded wall outlet to ensure safety features function correctly. Avoid using extension cords between the strip and the wall as this can reduce protection.
Check the safety indicator light regularly to confirm surge protection is active. If the light is off the protection may be damaged and needs replacement.
Do not exceed the maximum wattage rating to prevent overheating or fire risks. Allow the strip to rest if running high power devices for extended periods.
