For most home internet setups, I’d start with the CyberPower CP1500AVRLCD3: its 1500VA/900W capacity and LCD make it a flexible choice when you want room for a modem, router, and other network gear. The APC BE600M1 is a more compact fit for a simple modem-and-router pair, while the GoldenMate 1000VA/800W stands apart with lithium battery technology. The main tradeoff is between a smaller unit that suits basic equipment and a larger backup that offers more capacity but takes up more space. Runtime depends on the power draw of your specific devices, so capacity alone does not tell the whole story. Read on for my full comparison and guidance on choosing the right UPS for your home internet.

Key Takeaways
- The CyberPower CP1500AVRLCD3 leads as a flexible home-internet pick because its 1500VA/900W capacity and LCD support a wider range of connected equipment than the smallest models.
- Compact UPS models suit a modem and router better than a crowded desk: the APC BE600M1, CyberPower ST425, and APC BE425M offer lower-capacity alternatives for simpler setups.
- More capacity is not a runtime guarantee: actual backup time depends on the combined wattage of the modem, router, and any other connected devices.
- The CyberPower CP1500PFCLCD is the standout when sine-wave output matters, while the larger APC BX1500M provides another high-capacity option without that specific feature in its listed name.
- The GoldenMate 1000VA/800W is the lineup’s lithium option, giving buyers a distinct battery-technology choice rather than another conventional-looking capacity step.

Our verdict“Choose the CP1500AVRLCD3 for a larger home internet setup with many connected devices, provided a few minutes of backup is enough.”
CyberPower SL700U 700VA/370W Standby UPS Battery Backup and Surge Protector
The SL700U suits buyers who want a slim UPS near a modem and router without giving up much floor or desk space. Its keyhole slots allow wall mounting, a placement option the larger CyberPower CP1500AVRLCD3 does not emphasize. Five of its eight outlets provide battery backup, leaving three for surge-only equipment, and its two USB-A ports can charge devices with a shared 2.4A output. This is a simpler standby model, though: it lacks the CP1500AVRLCD3’s AVR and LCD monitoring, and its listed runtime is only two minutes. The simulated sine wave output and limited backup window make it a better fit for basic home networking than a setup where several power-hungry devices need support.
Pros:- Slim enclosure and keyhole slots support discreet wall mounting
- Five battery-backed outlets suit a basic modem-and-router setup
- Eight outlets include three surge-only connections for less critical devices
- Two USB-A ports provide shared 2.4A charging
Cons:- Listed runtime is two minutes

CyberPower CP1500PFCLCD 1500VA/1000W Sine Wave UPS with Battery Backup and Surge Protection
For home internet gear paired with a computer or other equipment that calls for clean sine wave output, the CP1500PFCLCD is the most capable fit here. Its pure sine wave output supports active PFC power supplies, unlike the simulated sine wave CyberPower CP1500AVRLCD3 and SL700U. It also offers 1500VA/1000W capacity, AVR, and a tilting color LCD, making it easier to monitor a more involved home setup. The tradeoff is size and weight: at 24.9 pounds, it is less convenient to move or tuck into a tight space. As with the other large CyberPower option, only six of its 12 outlets have battery backup, so plan which devices matter most during an outage.
Pros:- Sine wave output supports active PFC and conventional power supplies
- 1500VA/1000W capacity offers more output headroom than the CP1500AVRLCD3
- AVR helps manage minor voltage fluctuations without using battery power
- Tilting color LCD and USB-A and USB-C ports support monitoring and charging
Cons:- Six of the 12 outlets are surge-only rather than battery-backed

APC Back-UPS BE600M1 600VA/330W Battery Backup and Surge Protector
The APC Back-UPS BE600M1 is a compact choice for buyers whose priority is keeping a modem and router powered through a brief interruption, rather than backing up a whole room. Its listed 23-minute runtime at 100W gives a more useful reference point for a light load than the short runtime figures supplied for the CyberPower SL700U and ST425. Five battery-backed outlets leave room for network equipment and a few other essentials; two more outlets provide surge protection only. The unit is also wall-mountable, and its user-replaceable battery can extend its service life. Its 600VA/330W capacity is limited, however, and the replacement battery is sold separately. Buyers with a larger setup should look to a higher-capacity option such as the CP1500AVRLCD3.
Pros:- Listed runtime of 23 minutes at a 100W load offers a useful light-load reference
- Five battery-backed outlets can support essential networking equipment
- User-replaceable battery can extend the unit’s useful life

Our verdict“Choose the BE600M1 for a compact modem-and-router backup with a stated light-load runtime, but skip it for a larger electronics setup.”
CyberPower ST425 Standby UPS Battery Backup and Surge Protector
The CyberPower ST425 is a straightforward option for a small home internet setup where the goal is brief backup and surge protection, not extended runtime. Its eight outlets include four battery-backed connections, which can cover a modem and router while leaving surge-only outlets for less critical gear. Compared with the APC Back-UPS BE600M1, it offers one more total outlet but less capacity and no stated longer runtime; its listed runtime is one minute. The compact design, transformer-spaced outlets, and LED indicators make placement and basic status checks simple, but there is no LCD or AVR. Its simulated sine wave output also limits its fit for devices that need sine wave power. I’d reserve it for low-draw essentials and choose the BE600M1 when longer stated runtime matters more.
Pros:- Eight outlets include four battery-backed connections
- Compact design includes transformer-spaced outlets
- LED indicators show power status and wiring faults
- Three-year warranty covers the battery
Cons:- Listed runtime is one minute

Our verdict“Pick the ST425 for a compact, low-capacity backup for essential home network gear, not for sustained internet service during an outage.”
APC BX1500M 1500VA/900W UPS Battery Backup and Surge Protector
The BX1500M is my pick for home internet setups that also need backup for a desktop, monitor, or other office electronics. Its 900W capacity gives it far more headroom than the APC BE425M, which is better kept to a modem and router. Five outlets provide battery backup, while five more offer surge protection only, so I can reserve battery power for the devices that keep internet access available. AVR corrects qualifying voltage dips without drawing on the battery, and the LCD reports load and estimated runtime. Coaxial and Ethernet surge protection add useful connections for a network setup. The tradeoff is size and capacity that may be unnecessary for just a modem and router; runtime falls as the load grows, and the battery is sold separately when replacement is needed.
Pros:- 900W capacity supports a broader home-office load than the APC BE425M.
- Five battery-backed outlets are separate from five surge-only outlets.
- AVR corrects qualifying low voltage without using battery power.
- LCD monitoring, replaceable battery, and coaxial and Ethernet surge protection.
Cons:- Runtime depends on the connected load and may be limited when several devices are attached.
- Replacement battery is sold separately.
- Stepped approximation sine-wave output may not suit every connected device.
Best for: Home internet users who also want battery backup for a computer and several other compatible home-office devices.

- Data-line protection:Coaxial and Ethernet
Our verdict“Choose the BX1500M if your home internet backup needs to cover a modem and router alongside a substantial home-office setup.”
GoldenMate 1000VA/800W Lithium UPS Battery Backup and Surge Protector
For buyers who want a UPS that may need fewer battery replacements over its service life, the GoldenMate 1000VA/800W stands apart with a LiFePO4 battery rated for more than 5,000 charge cycles and up to 10 years of battery life. That makes it a different kind of choice from the lead-acid APC BX1500M: the GoldenMate offers less capacity, but its battery chemistry is the main draw. Its pure sine wave output and eight battery-backed outlets suit a modem, router, and compatible networking or computer equipment. An LCD shows power conditions, and the buzzer can be muted. This tower is less compelling if you want a compact, quiet unit: its cooling fan can run under heavy battery use, and a full charge is listed at 10 hours. The supplied runtime figure is 30 minutes, but actual duration depends on load.
Pros:- LiFePO4 battery rated for more than 5,000 charge cycles.
- Pure sine wave output for compatible equipment.
- Eight outlets provide battery backup and surge protection.
- LCD status information and a mute option for the buzzer.
Cons:- Cooling fan may activate during heavy battery use.
- Listed battery charge time is 10 hours.
- Lower capacity than the 900W APC BX1500M.
Best for: Home internet users who want a long-cycle-life battery and pure sine wave output for a modem, router, and compatible network equipment.
Not ideal for: Buyers prioritizing a compact, fanless UPS, or those who need more than 800W of capacity.
- Capacity:1000VA / 800W
- Battery type:LiFePO4
- Battery life and cycles:Up to 10 years; more than 5,000 charge cycles
- Outlets:8 NEMA 5-15P
- Waveform:Pure sine wave
- Input and output voltage:90–140V AC input; 120V output
- Runtime and charge time:30 minutes runtime; 10 hours to charge
- Form factor and display:Tower; LCD panel
Our verdict“Pick the GoldenMate if long battery cycle life and pure sine wave output matter more to your home internet setup than maximum capacity or a quiet, compact design.”
APC Back-UPS 650VA/390W Battery Backup and Surge Protector, BE650G1
The APC BE650G1 is a straightforward choice when the goal is keeping a modem and router powered through a short interruption, without paying for capacity intended for a larger office setup. Its 650VA/390W rating sits between the compact APC BE425M and the much larger APC BX1500M. Four outlets have battery backup, leaving four surge-only outlets for devices that do not need to stay on during an outage. Status indicators, audible alerts, and data-line surge protection make it easier to monitor a basic network setup. APC lists up to 22 minutes at a 100W load, but runtime changes with the equipment connected. Compared with the BE425M, this model gives more capacity and outlets, though it is also heavier and larger. Only four outlets keep running on battery, and replacement battery cost is separate.
Pros:- Four battery-backed outlets plus four surge-only outlets.
- Up to 22 minutes listed runtime at a 100W load.
- Status indicators, audible alerts, and data-line surge protection.
- More capacity than the APC BE425M for a broader home internet setup.
Cons:- Only four of the eight outlets provide battery backup.
- Replacement battery is sold separately.
- At 13.6 lb, it is heavier than the compact APC BE425M.
Best for: Households that want a mid-capacity UPS for a modem, router, and a few additional low-power devices.
Not ideal for: Buyers who need all outlets battery-backed, long outage coverage, or a particularly lightweight wall-mounted unit.
- Capacity:650VA / 390W
- Input and output voltage:120V
- Outlets:8 total: 4 battery backup and surge protected, 4 surge-only
- Listed runtime:Up to 22 minutes at 100W load
- Battery:User-replaceable; replacement sold separately
- Dimensions:11.89 × 7.09 × 3.46 in
- Weight:13.6 lb
- Warranty:3 years
Our verdict“Choose the BE650G1 for basic home internet backup with room for a few additional devices, but skip it if every connected outlet needs battery power.”
CyberPower EC850LCD Ecologic UPS Battery Backup and Surge Protector
The CyberPower EC850LCD makes sense for a home internet station that shares space with a computer and several peripherals. Its 12 outlets exceed the eight on the APC BE650G1, while six provide battery backup and six are surge protected; three of the surge outlets are ECO-controlled to switch off peripherals when a connected computer is off or asleep. That feature is more useful for managing a desk setup than for a modem-and-router-only load. The LCD displays battery and power information, and the three-year warranty includes the battery. The key limitation is the listed two-minute runtime, so I would not choose it for extended connectivity through an outage. Its simulated sine wave output also makes it a less specialized option than the pure sine wave GoldenMate for equipment that calls for that waveform.
Pros:- 12 outlets, including six battery backup outlets.
- ECO-controlled outlets can shut off peripherals when a connected computer is off or asleep.
- LCD shows battery and power conditions.
- Three-year warranty includes the battery.
Cons:- Listed runtime is only 2 minutes, limiting outage coverage.
- Uses simulated sine wave output rather than pure sine wave.
- ECO-controlled outlets are less useful in a modem-and-router-only setup.
Best for: Home-office users who need many outlets for a computer, networking equipment, and peripherals, with ECO-controlled power management.
Not ideal for: Buyers whose priority is keeping internet online for a long outage, or who need pure sine wave output.
- Model and capacity:EC850LCD; 850VA / 510W
- Outlets:12 total: 6 battery backup and 6 surge protected
- ECO outlets:3 ECO-controlled surge-protected outlets
- Runtime:2 minutes
- Output waveform:Simulated sine wave
- Battery type:Sealed lead acid
- Warranty:3 years, including battery
- Connected equipment guarantee:$100,000
Our verdict“Choose the EC850LCD for a crowded home-office setup where outlet count and peripheral control matter more than extended modem-and-router runtime.”
APC BE425M 425VA/255W UPS Battery Backup and Surge Protector
For the narrow job of keeping a modem and router online, the APC BE425M is the most focused pick in this group. Its 425VA/255W capacity is suited to low-power electronics, and the compact case can sit on the floor or mount on a wall. Four of its six outlets have battery backup, leaving two surge-only outlets for devices that can shut down during an outage. APC lists up to 15 minutes at a 100W load; a modem-and-router pair may draw less, but actual runtime depends on the load. Compared with the BE650G1, this unit is lighter and easier to place, but it gives up capacity and two outlets. It is not the right fit for a desktop-heavy setup or long outages, and only four outlets stay powered by the battery.
Pros:- Compact 425VA/255W design suited to low-power network equipment.
- Four battery-backed outlets and two surge-only outlets.
- Can be wall-mounted or placed on the floor.
- Includes status indicators, audible alarms, and a wiring fault indicator.
Cons:- Limited capacity and runtime under heavier loads.
- Only four of six outlets provide battery backup.
- Listed battery average life is three years.
Best for: People who want a compact, wall-mountable backup focused on a low-power modem and router.

- Battery average life:3 years
- Dimensions and weight:4.13 × 9.98 × 5.52 in; 5.7 lb
- Mounting and warranty:Wall-mountable or floor placement; 3-year warranty
Our verdict“Choose the BE425M when you want a small, simple UPS for a modem and router rather than backup for a larger home-office load.”
How We Picked
I ranked these UPS units around the job readers are trying to do: keep a modem and router powered through an outage so home internet can remain available when the service provider’s network is still operating. I compared listed VA and watt capacity, output type where specified, form factor cues, LCD or other monitoring features, and how much extra connected equipment each unit can plausibly accommodate. I gave the lead position to the CyberPower CP1500AVRLCD3 for its balance of capacity and at-a-glance monitoring, rather than treating the largest rating as an automatic win.
Lower-capacity units rank well for readers who want a simpler, smaller setup, but they are less suited to adding several devices. Models with specialized features or battery technology earn distinct roles, not automatic top placement: sine-wave output matters for some equipment, while lithium chemistry may appeal to buyers comparing battery formats. Product names and listed ratings cannot establish runtime for a particular installation, so I avoid promising a specific number of minutes. Buyers should check device wattage, outlet layout, and the manufacturer’s runtime information before choosing.
Factors to Consider When Choosing Ups For Modem And Router
A UPS for home internet is a small system decision, not just a capacity contest. I’d start with what must stay online, then match the unit to that load and the space available.
1. Decide Which Devices Need Backup
List the equipment that must remain powered: usually the modem and router, but possibly a separate optical network terminal, mesh node, or network switch. Each extra device draws from the same battery, so backing up a whole desk can shorten the time available to your internet equipment. A common mistake is plugging every nearby device into battery-backed outlets simply because they are available. Keep essential networking gear on battery and use surge-only outlets for less important electronics, if the UPS provides them. Also check that the outlet layout accommodates the adapters and plugs in your setup.
2. Match Watt Capacity to the Actual Load
VA and watt ratings describe limits, not a guaranteed backup duration. Check the power draw printed on each device or its power adapter, add the loads you plan to connect, and leave headroom rather than operating at the UPS limit. Modems and routers often draw less power than desktop computers, which is why a lower-capacity unit can be enough for a basic network pair. Still, adding a mesh system or other equipment changes the calculation. Do not assume that a 1500VA unit will keep your internet running a fixed number of hours; consult the manufacturer’s runtime chart for an estimate at your combined watt load.
3. Think About the Outage You Need to Cover
A UPS can bridge brief power interruptions or give you time to shut equipment down, but it cannot keep internet service working if the provider’s local equipment also loses power. For short outages, a compact model may meet the need; longer interruptions call for closer attention to battery capacity and published runtime at your load. Decide whether your goal is to avoid a brief Wi-Fi drop, maintain access during a typical short outage, or support a wider group of devices. Those goals can point to different sizes even when the same modem and router are involved. A bigger rating can offer flexibility, but it also brings a larger unit and does not remove the need to check runtime data.
4. Check Output Compatibility Before Paying More
Most buyers powering a modem and router can begin by checking the UPS output and their equipment’s power requirements. A sine-wave model such as the CyberPower CP1500PFCLCD may make more sense when other connected equipment calls for that output, but it is not a reason by itself to buy a larger unit for basic network gear. Look at the specifications for any additional devices, especially if they have power supplies with specific compatibility requirements. Do not confuse surge protection with battery backup: confirm which outlets provide each function. Paying for a feature your devices do not need may be less useful than choosing a unit with the right capacity and outlet arrangement.
5. Plan for Battery Replacement and Placement
A UPS battery is a consumable component, so consider how replacement works before settling on a model. Check the manufacturer’s guidance on battery availability, service, and replacement procedure rather than assuming every unit is maintained the same way. The GoldenMate in this lineup uses lithium battery technology, which gives it a different battery format from the other listed models, but buyers should still review its own care and replacement information. Measure the space near your modem and router, allow for ventilation, and place the unit where its status display or indicators remain accessible. A model that fits the shelf and can be maintained is more useful than one chosen on capacity alone.

It can keep your modem and router powered, but that does not guarantee that your internet provider’s service will remain available. The provider’s equipment serving your home may also lose power during a wider outage. A UPS is most useful for local power cuts when the external network remains active. Connect only the networking devices you need and check their combined power draw against the UPS specifications. If you need internet for work or emergencies, ask your provider how its service behaves during outages in your area.
Is a 1500VA UPS too large for just a modem and router?
Not necessarily, but it may be more capacity and physical bulk than a basic setup needs. A higher-capacity unit can leave room for additional networking equipment or other devices, while a compact UPS may be a tidier match for a modem and router alone. Compare the unit’s size and outlet arrangement with your available space, not just its rating. Check runtime estimates at your actual load, since the VA number alone does not predict how long the network will stay powered. If you do not plan to expand, a smaller model may be a simpler fit.
How do I estimate how long a UPS will power my modem and router?
Find the wattage for each device, add the numbers, and use the UPS maker’s runtime chart for that load. If a device lists volts and amps rather than watts, its power adapter label can still help, though the figures may represent a maximum rating rather than typical use. Runtime changes with the connected load and battery condition, so treat published estimates as a guide rather than a guarantee. Avoid adding unnecessary equipment to battery-backed outlets if maintaining internet access is the priority. For this lineup, the product ratings alone do not provide enough information to promise a specific runtime.
Should I choose a sine-wave UPS for a modem and router?
For a basic modem-and-router setup, check the equipment makers’ power requirements before paying extra for a particular output type. The CyberPower CP1500PFCLCD is the listed sine-wave option here, so it is a more distinct choice for buyers whose connected equipment calls for that feature. If you plan to power other devices alongside networking gear, assess those devices too. Do not assume that sine-wave output automatically means longer runtime or greater backup capacity. The right choice depends on compatibility and the total load, not the feature name alone.
Can I plug a mesh Wi-Fi system or network switch into the same UPS?
Usually you can connect additional networking equipment if the UPS outlet type and capacity support it, but each device adds to the total load. Add the watt draw of the mesh nodes or switch to the modem and router figures, then check the unit’s watt limit and runtime chart. This can make a higher-capacity model more suitable than one intended for a simple two-device setup. Avoid connecting devices that are not needed to keep your home internet available. Also verify that the UPS has enough usable outlets for your adapters without blocking neighboring sockets.
Conclusion
For most readers who want a flexible UPS for home internet, I’d choose the CyberPower CP1500AVRLCD3 as best overall for its 1500VA/900W capacity and LCD monitoring. The APC BE600M1 is my best value-style choice for a basic modem and router, while the CyberPower CP1500PFCLCD is my premium pick for buyers who specifically want sine-wave output and higher capacity. For beginners with a simple setup, I’d start by comparing the APC BE425M or CyberPower ST425 and checking their limits against the devices’ power draw. Choose the GoldenMate 1000VA/800W if lithium battery technology is a priority. Whichever one you select, match the UPS to your actual connected load and check manufacturer runtime guidance before expecting a particular amount of backup time.
