    For any reason – be it a storm or a localized blackout, losing internet connection is a nightmare in the digital age. Thankfully, technology has allowed many devices to be developed to ensure that you have a plan B when that happens. In this article, we are going to be explaining how battery backups work and laying out for you our top picks for the best battery backup for wifi routers.

    What is a Battery Backup and Why do I Need One for my Wifi Router?

    A battery backup, also known as Uninterrupted Power Supply (UPS), is a dedicated battery that provides your electronics with power even when blackouts or electricity fluctuations happen. Their main purpose is for protecting desktop computer hardware since inconsistent electricity flow can and usually does cause permanent damage to your device. That being said, it is also encouraged for you to use a UPS with your wifi router as they are also prone to hardware damage from sudden surges and drops in electricity.

    Another reason to use a UPS for your router (and modem, if they’re separate devices) is to be able to stay connected to the internet no matter what interruptions may occur. It will enable you to continue working online even in blackouts until the power comes on or until a backup generator is activated.

    How to Use a Battery Backup for your Wifi Router?

    We will cover two ways on how to use a battery backup for your wifi router: through a UPS and through a power bank.

    Uninterrupted Power Supply (UPS)

    CyberPower Intelligent LCD Series on desk

    Firstly, you need to place your battery backup between the outlet and your router and modem. The set up would be your router and modem plugged into the battery backup, and your battery backup plugged into the wall. More than powering up your router when electricity is out, it also provides a steady stream of electricity as well as controls spikes or surges.

    APC Back-UPS (BEM600M1)


    The APC Back-UPS (BEM600M1) is a bulky power strip with seven 120V AC power outlets and a 1.5A USB port. Of the seven 120V outlets, five are supplied with battery power in the event of a blackout. Also, it was made to be placed at the floor so it’s a heavy duty option that can withstand being accidentally kicked or bumped without getting damaged. It can deliver two to six hours of battery life – five hours for a cable modem with wireless networking and four hours on a high-end modem and router combo. With all the features that this UPS has, you get great value with prices starting at $58.

    CyberPower Intelligent LCD Series


    The CyberPower Intelligent LCD Series is a towering UPS with a textured plastic casing around a shiny black face that positions it as a premium option. It’s only 3.9 inches wide with an LCD display lets you know the status of the device which is incredibly useful. Its size also makes it so that you won’t need to sacrifice much of your desk space for this UPS. It has an impressive over 15 hours of battery life that can power not just your modem and router but also a variety of other essential gadgets such as your PC or monitor. This UPS also has an alarm that alerts you when the power changes from AC to battery and when the battery is within 10 minutes of dying. It has 12 120V power outlets along the back for every device you may possibly want to charge. For its capabilities, the CyberPower Intelligent LCD Series is pretty expensive compared to the previous option but has great value for money with prices starting at $120.

    APC UPS Battery Backup (BR1500G)


    The APC UPS Battery Backup (BR1500G) is a premium offering from APC with a tower design and cooling vent that makes it possible to be operated from the side. It also has an LCD display similar to the previous option which shows some key information about the operation of the UPS such as the battery charge level, output voltage, and rate of battery drain. Aside from this, it has a huge battery that has 24 hours of power. Now another great feature that this APC model has is master power output control that allows one specific device to control the battery output. For example, you have your PC plugged in and you only want to turn it on from time to time whilst saving the battery when it’s not in use. So with the master power output control feature, you can set it up so that when the PC is plugged into the master port is the only time the rest of the outlets will be powered. This is great for both future emergencies and the environment. As for its value, it’s on the expensive side as it is a premium option at $160 but you would be getting a ton of great features with that price.
