Buying Guide – How to Choose the Best High Wattage Power Strip
Choosing the right power strip involves more than just counting outlets. Here are the key factors to consider for safety and performance.
Surge Protection Rating
Surge protection is measured in joules. Higher joule ratings like 4800J offer better defense against power spikes than lower ones. For sensitive electronics like computers, look for at least 2000J to ensure adequate safety.
Always prioritize higher joule ratings when protecting expensive equipment.
Outlet Count and Spacing
Consider how many devices you need to plug in simultaneously. Strips with 12 outlets are great for desks but ensure they have wide spacing to accommodate bulky plugs without blocking adjacent sockets.
Check spacing measurements to avoid outlet crowding.
Cable Gauge and Length
Thicker cables (12 AWG) handle high current better and reduce heat buildup. A 6 foot length is standard but measure your distance to the wall to ensure reach.
Opt for 12 AWG cord for high power applications.
Build Material
Metal housings dissipate heat better and resist physical damage compared to plastic. For workshops, metal is safer and more durable. Plastic is lighter for office use but can melt under extreme heat.
Use metal strips for workshops and plastic for desks.
USB Port Availability
Modern strips often include USB ports. Check if they support fast charging and the total output wattage. Some ports share power which limits speed for multiple devices.
Verify USB wattage if charging phones frequently.
Safety Certifications
Look for UL or ETL listings which certify safety standards. Also check for indicators that show when protection is active to avoid using an unshielded strip.
Never buy without UL or ETL certification.
Wall Mount Features
Some strips allow mounting to walls or under desks to save space. Mounting holes and low profiles make them ideal for organized setups.
Choose wall mount options for organized spaces.
Circuit Breaker Reset
A reset switch allows you to restore power quickly after a trip. Overload protection is essential for preventing fire hazards during high usage.
Ensure your strip has an accessible reset button.
How to Use and Care for Your High Wattage Power Strip
Place your power strip in a well ventilated area to prevent overheating. Avoid stacking other equipment on top of the strip which can block vents or cause heat buildup.
Regularly check the outlet and cord for signs of wear or discoloration. If you notice any strange smells or heat, unplug the strip immediately and inspect it for damage.
Turn off the strip using its switch when not in use for long periods. This saves energy and reduces the risk of surges during storms affecting your devices.
Frequently Asked Questions
What is the difference between a power strip and a surge protector?
A power strip simply extends outlets without safety features while a surge protector includes components to divert excess voltage. Always use a surge protector for sensitive electronics like computers and TVs.
Can I use a high wattage power strip outdoors?
Most indoor power strips are not rated for outdoor use and can be dangerous in wet conditions. If you need outdoor protection, look for strips specifically rated for weather resistance.
How do I know if my power strip is working?
Look for an indicator light that turns on when the protection is active. If the light is off, the protection may be disabled and you should replace the strip.
Is it safe to plug a power strip into another power strip?
No, plugging power strips together is called daisy chaining and significantly increases the risk of overloading and fire hazards. Always plug your strip directly into a wall outlet.
How long does a surge protector last?
Surge protectors lose effectiveness over time after absorbing hits. Even if the indicator is on, replace your strip every three to five years to ensure continued safety.
Do all power strips support USB charging?
No, standard strips only have AC outlets. Modern options include USB ports for convenience but verify the total wattage if you need to charge multiple devices simultaneously.
What does a 12 gauge cord mean?
The gauge refers to the thickness of the wire. A 12 AWG cord is thicker and carries more current safely than thinner cords which is why it is preferred for high power strips.
