Frequently Asked Questions (FAQs)

1. Is a 4000 joule surge protector good?

Units with surge protector ratings of 1000 to 2000 joules will provide sufficient protection for power tools and office equipment such as printers, copiers and routers. Consider the highest joule ratings—2000 and above—for home theater components, gaming consoles and any computer that stores important data…

2. How strong should a surge protector be?

A higher number indicates greater protection. Look for a protector that is at least rated at 200 to 400 joules. For better protection, look for a rating of 600 joules or more.

3. What is better than a surge protector?

While a surge protector functions like a power strip, uninterruptible power sources (UPS) work like temporary back up power. UPS devices work independently, providing power when the main power supply fails. A UPS protects users as well as devices during disrupted power.
