Short power cuts happen far more often than major blackouts, and each one knocks your internet offline, reboots your smart home and cuts off Wi-Fi security cameras and video doorbells right when you might want them. A small uninterruptible power supply (UPS) keeps your modem and router running through brief outages and gives you time to ride out longer ones. The best UPS battery backup for a router is compact, quiet and keeps your internet on for an hour or more.
We compared the most popular UPS units for home networks on run time with a typical router and modem, outlet layout, output type, battery chemistry, noise and price. Here are our picks for 2026.

How to choose a UPS for your router
1. Know how much power you need
A typical modem and router use about 10 to 30 watts together. Check the labels on your power adapters. Add any security hub or mesh node you want to keep running.
2. Pick run time over raw size
Look at the maker’s run-time chart for a 25 to 50 watt load. A small UPS can run a router for an hour or more, while larger units or DC models can run it for many hours.
3. Consider a DC UPS for long outages
DC UPS units power routers directly and waste less energy, so they last much longer on the same battery size. Make sure your devices’ plugs are supported.
4. Choose sine wave for computers
Simulated sine wave is fine for routers and modems. Pure sine wave is better for desktop computers with active power supplies.
5. Plan for battery replacement
Lead-acid UPS batteries usually last about three to five years. Choose a model with a user-replaceable battery, and recycle old ones properly.
Will my internet work during a blackout?
A UPS keeps your own equipment running, but your internet also depends on your provider’s network. During short outages, most networks keep working. In longer or wider outages, some neighborhood equipment may run out of backup power.
- Fiber service often uses a small box (an ONT) in your home that needs power too; plug it into the UPS.
- Cable internet usually stays up through short local outages.
- Plug your phone’s Wi-Fi calling and smart home hubs into the UPS so they keep working.
- For long outages, pair a UPS with a portable power station or generator to recharge it.
Frequently asked questions
How long will a UPS run my router?
It depends on the UPS size and how much power your gear uses. A small 600 VA unit often runs a router and modem for an hour or more; larger or DC units can run them for many hours.
Is a UPS the same as a surge protector?
No. Most UPS units include surge protection, but a surge protector alone does nothing when the power goes out.
Can I plug a power strip into a UPS?
Makers generally advise against it. Plug devices directly into the UPS’s battery-backed outlets.
Why does my UPS keep beeping?
It beeps to warn you that it is running on battery. Most models let you silence the alarm, and some beep when the battery needs replacing.
How often should I replace the UPS battery?
Lead-acid batteries usually last about three to five years. Many UPS units run a self-test and warn you when the battery is weak.
Will a UPS keep my security cameras running?
Wi-Fi cameras with their own batteries usually keep recording, but they need your router to send alerts. Keeping the router on a UPS helps them stay connected.
The bottom line
For most homes, the APC Back-UPS BE600M1 is the best UPS battery backup for a router, with five battery-backed outlets, a USB charging port and a 3-year warranty. Choose the CyberPower EC650LCD for a compact unit with a screen, the CyberPower CP1500PFCLCD to back up a PC too, or the APC Back-UPS Pro BR1500MS2 for a larger APC tower.
