Power outages are inevitable. Research shows that the average electricity customer in the United States loses experiences loses power for about two hours per year. If your power goes out, of course, you’ll typically lose internet access. Most consumer and commercial internet services feature a router, and routers require power.

Choose a Router With an Internal Battery

If you’re worried about losing internet access from power outages, you may want to choose a router with an internal battery. Some routers feature an expansion slot in which you can insert a battery, or they may come with a battery already installed in this slot. Regardless, an internal battery will keep them running during a power outage.

If the router loses power, it will automatically switch over to the internal battery. You won’t lose internet access. Rather, the internal battery will provide the necessary power to keep the router running until the utility power is restored.

Use an External Backup Battery

Even if your router doesn’t feature a built-in battery, you can use an external backup battery to keep it running during a power outage. External backup batteries are exactly what they sound like: batteries that are externally connected to devices for the purpose of providing those devices with emergency or backup power.

There are different types of external backup batteries, but most of them work the same way. You can plug your router into an external backup battery. You can then plug the external backup battery into a wall outlet via the original power adapter. If the power goes out, the external backup battery will keep it running.

Use a UPS

Another way to keep your router running during a power outage is to use an uninterruptible power supply (UPS). UPSs are similar to external backup batteries. Many people, in fact, use the terms “UPS” and “backup battery” synonymously. They are both batteries, and they provide emergency or backup power to the devices with which they are used. With that said, UPSs and external backup batteries aren’t necessarily the same.

UPSs are designed to constantly provide power to the devices with which they are used. After all, they are called “uninterruptible power supplies.” External backup batteries, on the other hand, will typically only provide power to devices when there’s a local power outage. A high-quality UPS may cost more, but it’s a smart investment that offers greater reliability during power outages.
