More Details on Our Top Picks

1. CyberPower AVRG750LCD Intelligent LCD UPS Battery Backup

   

   Best Overall for Moderate Power Backup and Versatility

   View Latest Price

   This model stands out for its balance between capacity and usability, making it ideal for small office setups or home routers and modems. Compared with the APC BE550G, it offers a higher capacity and more outlets, supporting multiple devices simultaneously. Its automatic voltage regulation helps maintain consistent power, which is essential during fluctuating outages. However, with a 750VA/450W limit, it may fall short if you need to back up higher-power devices or multiple electronics for extended periods.

   Best for Extended Runtime and User-Serviceable Batteries

   View Latest Price

   Compared with the CyberPower AVRG750LCD, the APC BE1050G3 offers a higher capacity of 1050VA/600W, making it better suited for longer backup needs and slightly higher loads.

With up to 36 minutes of runtime at 100W, it provides ample time during outages to save work or properly shut down equipment. The multiple outlets and USB ports add versatility, especially for small office networks and Wi-Fi setups. However, its larger size and weight can be cumbersome in tight spaces, and replacing the battery involves purchasing a separate model.

The color LCD panel offers detailed, real-time information—more comprehensive than the simple LED indicators on the APC BE550G—making it easier to monitor status. Despite its impressive features, its bulkier design may pose challenges fitting into tight spaces, and replacing the battery can require professional help. This UPS makes the most sense for tech-savvy users with active PFC supplies or high power demands who prioritize detailed monitoring and capacity.

   Best Budget-Friendly for Basic Router and Modem Backup

   View Latest Price

   Compared with larger models like the APC BE1050G3 and CyberPower CP1500PFCLCD, the APC BE550G offers a more affordable, compact solution for basic backup needs. Its 550VA/330W capacity is sufficient for powering a router, modem, and perhaps a small smart device during short outages, with up to 29 minutes of runtime at 100W. The straightforward design includes easy-to-read status indicators and a user-replaceable battery, reducing long-term costs.

   • Protection:$75,000 Equipment Protection
   • Warranty:3 years
   • Additional:User-replaceable battery
   Our verdict

5. APC UPS 600VA/330W Battery Backup for Computer, Router, NAS

   

   Best Compact Choice for Short-Term Router and Modem Power

   View Latest Price

   In comparison to the APC BE550G, the 600VA/330W model offers a slightly higher capacity, making it more suitable for supporting a router, modem, and small devices during brief outages. Its 23-minute runtime at 100W provides enough buffer to save work or safely shut down equipment, especially for users with minimal backup needs. The USB port allows for easy device charging, adding convenience. The battery is easily replaceable, helping keep long-term costs manageable. However, its limited outlets—only five with backup—restrict support for multiple devices, and its runtime diminishes quickly under higher loads. This pick makes sense for users seeking a small, simple backup solution for essential devices, but not for those needing longer or more comprehensive power support.

   Pros:

   • Compact and easy to place in tight spaces

   • Outlets:5 with backup + surge, 2 surge-only
   • USB port:1.5A
   • Warranty:3 years

   This APC 600VA unit stands out for providing reliable backup power with a compact design, making it ideal for small offices or home setups. Compared with larger models like the APC 1500VA/900W BX1500M, it offers less runtime but remains easy to place and manage. Its 30-minute runtime at 100W is sufficient for short outages, and the USB port adds convenience for device charging. The easy battery replacement feature helps keep ongoing costs manageable. However, the limited runtime for higher loads and the fact that it’s refurbished introduce potential reliability concerns over time.

   The PowMr 1500VA/800W UPS is well-suited for small businesses or demanding home setups that need dependable power during outages. Its robust capacity surpasses the APC 600VA unit, offering more headroom for multiple devices or longer outages. The ultra-fast transfer time and voltage stabilization features help keep sensitive electronics protected, especially compared to less sophisticated models.

   Best for Office Electronics and Longer Runtime

   View Latest Price
   The APC BX1000M provides a reliable backup for office electronics with over 42 minutes of runtime at 100W, making it ideal for small office environments. Its automatic voltage regulation (AVR) ensures stable power, especially compared to less sophisticated models like the APC 600VA, which lack this feature. The user-replaceable battery is a plus for ongoing maintenance, and the LCD display offers real-time insights. However, its 600W limit means it can’t support high-power devices, and the absence of built-in USB charging ports limits device flexibility. For small offices seeking longer backup and real-time monitoring, this unit offers a solid balance of features and capacity.
   Pros:

Its automatic voltage regulation helps maintain stable power, reducing stress on connected devices, which makes it more versatile than smaller models like the APC 650VA. The energy efficiency certification supports ongoing energy savings, but the bulkiness and the need to purchase batteries separately may deter those with limited space or budget. It’s best suited for environments where power stability and extended backup are priorities, rather than compactness or immediate affordability.
   Pros:

   • Provides up to 68 minutes of backup at 100W

Its 22-minute runtime at 100W is enough for quick outages, and the user-replaceable battery extends its lifespan without replacing the entire unit. Compared with larger models like the APC 1000VA/600W, this unit has fewer outlets and less capacity, but its size and price make it accessible for users with minimal backup needs. The absence of USB ports limits device charging options, which might be inconvenient for some. It’s a practical choice for those prioritizing affordability and simplicity over extended runtime or advanced features.
    Pros:

    • Reliable power during outages

11. CyberPower CP1500AVRLCD3 Intelligent LCD UPS Battery Backup

    

    Best Overall for Reliable Power Management

    View Latest Price

    The CyberPower CP1500AVRLCD3 stands out for its substantial capacity of 1500VA/900W, making it suitable for protecting multiple devices at once, including workstations and network gear. Its color LCD display provides detailed real-time info, surpassing APC’s 850VA model in transparency and monitoring. The inclusion of automatic voltage regulation (AVR) helps maintain steady power, a feature less emphasized in smaller or lower-capacity units.

Compared with the APC 850VA, this UPS offers more capacity but sacrifices portability and slightly increases complexity. It’s a great choice for those needing dependable, multi-device backup with detailed monitoring, but less so for users seeking a lightweight, simple solution.

    Pros:

    • High capacity suitable for multiple devices
    • Color LCD display with detailed real-time info
    • Automatic voltage regulation stabilizes fluctuating power

    Cons:

    • Heavy and bulky, less portable

    • Input:NEMA 5-15P plug with 6-foot cord
    • USB ports:1 Type-A, 1 Type-C
    • Display:Color LCD panel
    • Warranty:3 years including battery

12. APC 850VA/450W UPS Battery Backup & Surge Protector for PC, Router, NAS

    

    Best Value for Essential Device Backup

    View Latest Price

    The APC 850VA/450W offers a balanced blend of capacity and affordability, making it suitable for protecting a single PC, router, or small NAS setup. Its 9 outlets, including 6 with battery backup, provide enough room for essential devices, and the user-replaceable battery simplifies ongoing maintenance, unlike the CyberPower model which requires professional servicing. While it doesn’t match the higher capacity of the CyberPower or the detailed display of the APC 1500VA, it still covers the basics efficiently. Runtime at 100W is up to 35 minutes, but this diminishes quickly with higher loads, which could be limiting for longer outages. This model strikes a good balance for small offices or home users needing reliable backup without extra frills, but it isn’t suited for powering multiple high-demand devices simultaneously.

    • Reliable backup power for essential devices
    • Multiple outlets including USB charging ports
    • User-replaceable battery for easy maintenance

    Cons:

    • Limited runtime for high loads

Understanding these elements can help prevent common pitfalls like overbuying or choosing a model that fails to support your equipment during outages. Here are key considerations to keep in mind:

Capacity and Runtime

The capacity of a UPS, measured in VA or watts, determines how long it can keep your devices powered during an outage. For router and modem backup, a smaller capacity often suffices, but higher capacity models extend runtime, especially if you add a switch or other networking gear. Be cautious not to choose a UPS with just enough capacity—consider future needs or additional devices to avoid short runtimes that may leave you disconnected when you need backup most.

Pure Sine Wave vs. Simulated Sine Wave

Pure sine wave UPS units produce cleaner power, which is gentler on sensitive electronic components like modems and routers. While they tend to be more expensive, they reduce the risk of hardware issues caused by power fluctuations. Simulated sine wave models are often cheaper but may cause minor disturbances or noise, making them less ideal for critical networking equipment in a business setting.

Ease of Setup and Management

For small businesses, straightforward installation and management features matter. An LCD display can provide real-time status updates, while automatic shutdown features prevent data loss during extended outages. Avoid overly complex models if you’re unfamiliar with electrical setups; simplicity can save time and reduce errors during deployment and maintenance.

Surge Protection and Additional Features

A good UPS isn’t just about backup power—surge protection safeguards your network equipment from voltage spikes. Additional features like multiple outlets, network management, and remote monitoring can enhance reliability and convenience. Weigh these extras against cost, especially if your primary goal is just to keep internet access live during brief outages.

Price and Value

While higher-capacity models offer longer runtime and advanced features, they come with a higher price tag. For most small business setups focused solely on router and modem backup, a mid-range model provides the best balance. Avoid overspending on features you won’t use, but don’t compromise on essential capacity that guarantees your network stays online when power fails.

Frequently Asked Questions

How long should my UPS keep my router and modem powered during an outage?

For most small businesses, a backup duration of 15 to 30 minutes is sufficient to save work or properly shut down equipment. If your internet connection is critical for ongoing operations, consider a UPS with a longer runtime, typically 1 hour or more, especially if you need to sustain connectivity during extended outages or for remote work scenarios.

Is a pure sine wave UPS necessary for router and modem backup?

While not strictly necessary, a pure sine wave UPS offers cleaner power, which reduces the risk of hardware issues caused by power fluctuations. For sensitive networking equipment, especially in environments with unstable power, investing in a pure sine wave model can improve reliability and lifespan of your devices, though at a higher cost.

Can I use a regular office UPS for my home router and modem?

Yes, many office-grade UPS units are suitable for home router and modem backup, provided they have enough capacity and runtime. However, ensure the UPS supports the power requirements of your devices and includes surge protection. For typical home setups, smaller capacity models often suffice, but larger units provide more extended backup if needed.

What are the main tradeoffs when choosing a higher-capacity UPS?

Higher-capacity UPS units generally cost more and are bulkier, which might be a concern for limited space. They also tend to consume more energy even when idle, increasing operational costs. However, they offer longer runtime and support for additional devices, making them ideal for environments where prolonged outages are common or where multiple networking devices need backup power.

Should I prioritize surge protection or backup runtime?

Both are important, but if your primary concern is keeping your internet connection live during short outages, focus on a UPS with adequate backup runtime. Surge protection is a valuable bonus that can prevent damage from voltage spikes. For critical business operations, aim for a model that balances both features to protect your equipment and maintain connectivity effectively.
