The Best Battery Backup For Wi-Fi Routers

We all have some experience with the incredible frustration of watching the Wi-Fi go down. While laptops and tablets can run on battery, when the power goes off, your Wi-Fi becomes unusable. Over a prolonged period, this can have a real effect on your day-to-day life.

When this happens, you need a backup power source for the Wi-Fi. This way, you can stay connected no matter what the power is doing. A perfect plan B that ensures your connection never gets interrupted.

The Best Battery Backup For Wi-Fi Routers

To help you find the right battery backup for your Wi-Fi router, we’ve put together this guide. We cover how a backup works, why you need one, and what backup to invest in.

We also cover some alternative charging solutions. You never have to read those dreaded “connection lost” notices again!

What Is A Battery Backup For Wi-Fi? Do I Need One?

The battery backup is otherwise known as an Uninterrupted Power Supply (UPS), and this gives some better context to what they actually are.

A UPS is designed to consistently provide your devices with electricity. The main reason for this is to avoid damage from an inconsistent power supply. 

A sudden surge or less of electricity can cause damage to hardware. This is partly why we tend to see battery backups connected to desktop computers. If the power drops and comes back again, it could cause permanent damage. A UPS can ensure this doesn’t happen.

Changes in electrical charge can also damage the hardware of a Wi-Fi router. For that reason, if you suffer from regular power outages, it’s worth considering a UPS.

The other reason is that when the power is out, the router can’t work. So, even if you have a fully charged laptop, you can’t connect to the internet. A battery backup makes sure you can continue to work (or play) until the power comes back on.

Similarly, if you have young children, a battery backup can keep the Wi-Fi going for kids, so they stay occupied during a nervy blackout.

Which Battery Backup Is Best For Wi-Fi Routers?

The most common way to use a battery backup for a Wi-Fi router is the Uninterrupted Power Supply. However, this isn’t your only option. Instead, you can use a power bank to keep your Wi-Fi going. In this guide, we’ll cover the best devices for each option.

Uninterrupted Power Supply

The Uninterrupted Power Supply is connected between the outlet and modem. It powers the modem and router at all times, ensuring a steady supply of electricity, and controlling spikes. This helps to keep your router healthy.

The high-powered CyberPower UPS set up is a fantastic design that provides enough output to keep your Wi-Fi going strong for up to 4 hours in a power cut.

In the meantime, it will quietly and efficiently correct any surges and spikes, protecting your router from damage.

With 6 battery and surge protected outlets, this UPS by CyberPower can keep your entire desktop running for several minutes in a power outage.

Enough time to save any essential work, and explain the situation to coworkers. 6 additional surge-protected outlets keep devices safe the rest of the time. 

The sleek finish and thin tower of the CyberPower UPS system fits neatly into a home office. A functional LCD panel can keep you informed of battery capacity, load capacity, and detailed information on the current power conditions.

Easy to read, you can stay on top of the power situation with minimal effort.

The CyberPower UPS system is an intelligent device, able to keep your batteries working safely for longer. When the power goes out, you’ll be grateful to have the CyberPower on your side — even if you rarely notice it’s there.


  • 3-year warranty - Peace of mind over an extended period.
  • Multifunctional LCD panel - Provides immediate information on the charge and power conditions.
  • Automatic Voltage Regulation (AVR) - Corrects power fluctuations without using the battery power, keeping the battery healthier for longer.


  • Not very versatile - This isn’t a budget machine, but there are better models available which do more. CyberPower can feel simplistic.

It may not come cheap, but there are more than enough benefits to the APC UPS unit to offset the costs. This is one of the most popular uninterrupted power supply units around, from a trusted brand with a strong reputation.

This is a fantastic choice if you have important data you can’t risk losing to unexpected power cuts.

The first thing to know about the APC UPS is that it can deliver up to 847 W, which is more powerful than the majority of home battery backup systems available. That means it can handle most of the gear you can throw at it, including sophisticated desktop set-ups. 

Another advantage to the APC UPS is the Sine Wave inverter. This provides smooth power, like you’d expect from a wall outlet, allowing you to power even sensitive machines.

Automatic Voltage Regulation is also included, protecting battery life from surges and spikes in electricity.

Two USB charger ports, a USB-C and a Type-A, allows you to charge small gadgets using the APC, as well as larger electronics.

An attractive and sleek design, the first and final impressions of the APC 1500VA battery backup are good. An LCD screen makes it easy to monitor the power, and the small size fits onto desks and desktops. 


  • 10 outlets, 6 with battery backup - A decent number of outlets, including 6 with battery backup and surge protection.
  • Replaceable battery - As your device ages, you don’t need to pay for an expensive replacement. Instead, you can just replace the battery.
  • Sine-Wave and AVR technology - Keep your electronics safe with smoother power and a healthier battery life.


  • Price - This is an expensive device.

If you want a simple UPS that can provide power to your Wi-Fi for a decent period of time, then the Amazon Basics UPS is a low budget choice that’s incredibly effective.

Small, and easy to use, this is a fantastic choice if you’re looking for peace of mind at a lower price.

With the Amazon Basics UPS installed, you can expect your Wi-Fi to continue for up to ninety minutes in a blackout.

Depending on your usage, this can be more than enough. There are 12 outlets in total, 6 of which are surge-protected, and 6 of which are surge-protected and battery-backup. 

Instead of using automatic voltage regulation, this device uses the less complex standby power management. This can put some strain on the battery, but for the average router it shouldn’t cause a problem.

The Amazon Basics Standby UPS also acts as a surge protector, keeping your router safe from sudden spikes of electricity. If this is a frequent issue, then the low-cost Amazon Basics UPS provides a simple solution.


  • Price - A cost-effective UPS that outperforms its price point.
  • 6 battery-backup outlets - Plenty of outlets for versatile charging.
  • Size - A compact machine, you’ll forget it’s there until your Wi-Fi stays on during a power cut.


  • Basic - The clue really is in the name. This is a simple device, with less power and fewer additions than the standard UPS. For frequent blackouts, it may not be enough.

Power Banks

A UPS may be the best way to provide backup battery power to your router, but it isn't the only way. If you rarely experience power cuts, you may not want to spend money on an expensive UPS that only has one use. In that case, you may prefer to use a power bank.

A power bank acts as an additional battery, and is commonly used for charging phones and laptops on long trips. They can also provide a few hours of extra charge for your Wi-Fi router during a power cut. 

In order to do this, you require a 5V or 12V booster cable, and a power bank equipped with pass-through charging.

The pass-through charging of the Goal Zero Sherpa power bank has many advantages, especially when powering a router.

With pass-through charging, a power bank can charge itself, while simultaneously charging other devices. So, plug it into your router, and the power bank provides back up energy during an unexpected blackout.

Another advantage to the Goal Zero Sherpa is that it’s Qi enabled. With Qi charging, you can power a compatible smartphone without the use of cables. So, while the Sherpa powers your modem, it’s also restoring charge to your phone.

  • Pass-through charging - The Goal Zero power bank can charge and be charged at the same time, for continuous usage.
