The single most important detail separating a dependable hardware guardian from a paperweight is its joule rating. A higher joule number means the strip absorbs more stray electricity before failing.
Finding the Best Surge Protectors for Modem and Router involves looking past standard power strips to find models with dedicated data line shielding. Power surges travel through coaxial cables and telephone lines just as easily as they travel through standard wall sockets.
Keep reading to see five top configurations designed to keep your networking equipment safe from erratic voltage.
Key Takeaways
- Prioritize a minimum joule rating of 2000 to ensure your sensitive networking hardware absorbs substantial electrical shocks without failing.
- Verify that the unit includes coaxial and ethernet ports so power spikes cannot sneak in through your internet service cables.
- Choose a model featuring automatic shutdown technology that permanently cuts power to connected devices once the internal components wear out.
- Look for spaced outlets or a flat plug design to accommodate bulky power adapters commonly used by modems and routers.
- Consider a mini DC uninterruptible power supply if you need continuous internet uptime during short power outages and brownouts.
