Buying Guide
What to Look For
Choose a UPS with sufficient capacity (VA/W) to support your modem and router simultaneously. Look for features like automatic voltage regulation (AVR), backup duration, and number of outlets. Portability and ease of installation are also key factors depending on your setup.
Common Mistakes to Avoid
Overloading the UPS by connecting too many devices reduces backup time and risks damage. Ignoring backup duration needs can leave you without power during outages. Not considering battery replacement costs might affect long-term affordability.
Additional Tips
Regularly test your UPS, keep batteries maintained, and choose models with clear monitoring indicators for peace of mind during outages.
FAQ
How long should a backup last for a typical modem and router?
Generally, 10-20 minutes is sufficient for saving work and shutting down properly or maintaining connectivity during brief outages.
Can I connect other devices to the UPS?
Yes, but ensure the total load does not exceed the UPS’s VA/W capacity to prevent overload and reduce backup time.
Conclusion
Choosing the right power backup for your WiFi router and modem ensures reliable internet access during outages. Consider capacity, features, and your specific needs to find the best fit. With the right UPS, stay connected no matter the power situation.
