Buying Guide

What to Look For

Choose a UPS with enough capacity (VA) to support your modem and router. Look for features like surge protection, runtime, LCD displays, and number of outlets. Ensure compatibility with your devices’ power requirements for seamless backup.

Common Mistakes to Avoid

Avoid underestimating power needs; selecting too small a capacity can lead to rapid shutdown. Don’t ignore runtime estimates—plan for longer outages. Also, neglecting surge protection can leave your equipment vulnerable.

Additional Tips

Opt for units with user-friendly features like LCD screens for status updates. Consider the size and weight if portability is important. Regularly test your UPS to ensure it functions properly when needed.

FAQs

How long should a battery backup last for modem and router?

Ideally, 10-15 minutes of runtime is enough to save work and shut down properly during short outages.

Can I connect other devices to my UPS?

Yes, but ensure the total power consumption doesn’t exceed the UPS’s capacity to prevent overload.

Conclusion

Choosing the best battery backup for your modem and router ensures continuous connectivity during outages. Focus on capacity, runtime, and surge protection features. The right UPS can safeguard your online activities and keep your network running smoothly when it matters most.
