1. Joule Rating: Look for a higher joule rating, which indicates the amount of energy the surge protector can absorb before failing. Aim for at least 1000 joules.

2. Clamping Voltage: Check the clamping voltage, which is the voltage level at which the surge protector begins to act. A lower clamping voltage offers better protection.

3. Response Time: Opt for a surge protector with a fast response time to ensure it can react quickly to power surges.

4. Number of Outlets: Choose a model with enough outlets to accommodate all your devices, considering future needs as well.

5. Battery Backup: If necessary, consider surge protectors that include battery backup for critical devices like computers.

6. Indicator Lights: Look for models that have indicator lights to show when the surge protector is functioning properly and when it needs replacement.

7. Form Factor: Depending on your setup, consider the design and size of the surge protector (e.g., wall-mounted vs. power strip).

8. Child Safety Features: For homes with children, consider surge protectors with safety shutters on unused outlets.

9. Warranty: Check the warranty or equipment protection policy offered, which can provide coverage for connected devices in case of a surge.

10. Brand Reputation: Purchase from reputable brands known for reliability and quality in surge protection.

11. UL Certification: Ensure the surge protector is UL (Underwriters Laboratories) listed, indicating it meets safety standards.

12. Physical Reviews: Read customer reviews to gauge real-world performance and reliability.

13. Price vs. Value: While cheaper options exist, investing in a higher-quality surge protector can save you money in the long run by protecting your devices.

By considering these tips, you can make a more informed decision when choosing a surge protector for your devices!
