Common Myths About Surge Protectors and Power Strips

When choosing between a surge protector and a power strip, it’s essential to separate fact from fiction. Let’s debunk some common misconceptions:

1. All Power Strips Provide Surge Protection

• The Myth: A power strip automatically includes surge protection because it looks like a surge protector.
• The Truth: Most power strips do not include surge protection. They merely expand the number of outlets available and offer no defense against voltage spikes. Always check the label or product description for the term “surge protection” and the joule rating.

2. Surge Protectors Last Forever

• The Myth: Once you buy a surge protector, it will protect your devices indefinitely.
• The Truth: Surge protectors have a finite lifespan. Each power surge they absorb reduces their capacity to protect, and eventually, they lose their effectiveness. Once the joule rating is exhausted, the surge protector acts like a regular power strip. Replace your surge protector every 2–3 years or after a significant surge.

3. A Surge Protector Can Stop Lightning Damage

• The Myth: A surge protector will prevent all types of electrical damage, even from lightning strikes.
• The Truth: While surge protectors can handle most minor and moderate surges, they may not withstand the massive voltage from a direct or nearby lightning strike. For maximum protection, consider a whole-house surge protector installed at your main electrical panel.

4. The Indicator Light on a Surge Protector Always Works

• The Myth: If the light on the surge protector is on, it’s still protecting your devices.
• The Truth: The indicator light typically shows whether the device is plugged in and receiving power. However, it doesn’t always reflect the surge protection’s status. To ensure your protector is still functioning, check the manufacturer’s specifications or replace it periodically.

5. All Surge Protectors Are the Same

• The Myth: Any surge protector will provide adequate protection, regardless of price or specs.
• The Truth: Surge protectors vary widely in quality and capacity. Cheaper models often have low joule ratings, slower response times, and fewer features. Investing in a higher-quality surge protector ensures better and longer-lasting protection.
