Router Battery Backups

Did you know it’s possible to stay connected to the internet during a blackout? We’re not just talking about cell service. With an Uninterruptible Power Supply system (often referred to as a battery backup), your router stays on. The length varies depending on the backup unit.

MEC Routers

  • 844 GigaCenter and U6x/U6xw routers received before August 2023 do have battery backups. They only power the router and the battery generally lasts about two hours if brand new, with that time decreasing as it ages. A backup for the U6x and U6xw will likely last about half that time, because it consumes more power than an 844GigaCenter.
  • U6 routers, U12 routers, mesh units, and U6x/U6xw routers received after August 2023 do not have battery backups. Keep reading to learn how to shop for one.

As with most things, you have lots of options when choosing a battery backup. Here are some things to consider.

Battery Life

Most importantly, you don’t want to waste money on a backup that runs out of energy too quickly.

With just your router plugged in, many battery backups will last you about 2-6 hours. If you’re counting on it to power your PC and hard drive as well, this could bring the run time down to about 10-20 minutes – long enough to save your work so the blackout doesn’t affect your data.

Some higher-end models can last much longer, while cheaper ones won’t necessarily reach these times.

When considering a backup, look at the manufacturer’s estimated run time for an idea of how long it will stay on.


Each battery backup is different. Some have extra outlets, some automatically regulate voltage, and some even include USB ports for charging small devices.

Before you start shopping, determine which devices you want to remain active during a potential outage. If you’ll use your backup for more than just your router, you might want to consider a higher-end model with more capabilities.


More expensive battery backups aren’t always better, especially if you don’t need all the extra bells and whistles.

On the other hand, spend too little and you could wind up with a system that doesn’t meet expectations.

Whenever you’re shopping for new technology, check reviews from other people who have purchased the device you’re considering. Instead of only looking at star ratings, read what people say they like and don’t like. Are there any positives or negatives that people keep mentioning? If so, do they change how you feel about the price tag?
