How we picked

• Capacity and runtime: How much power you need depends on what you're backing up. A router and modem need only 50W, but a full desktop PC and monitor can draw 300W or more. Look for models that give at least 15 to 30 minutes of runtime at your typical load.
• Output type: Pure sinewave inverters are essential for sensitive electronics like gaming PCs, CPAP machines, and variable‑speed appliances. Simulated sinewave is fine for basic power supplies but can cause issues with active PFC power supplies.
• Automatic Voltage Regulation (AVR): If your home experiences brownouts or voltage fluctuations, AVR corrects them without draining the battery, extending battery life and keeping equipment stable. This is a must for areas with unreliable grid power.
• Battery chemistry and lifespan: Traditional lead‑acid batteries need replacement every three to five years. LiFePO4 batteries last 10 years and thousands of cycles, making them ideal for frequent use or whole‑home backup. Portable power stations almost exclusively use LiFePO4 now.
• Portability and expandability: Fixed UPS units stay under a desk. Portable power stations can be moved room to room or taken camping, and many can be expanded with extra battery packs. Think about whether your needs might grow over time.
• Number and type of outlets: Make sure you have enough battery‑backed outlets for essential devices, plus surge‑only outlets for peripherals. USB charging ports are a bonus for phones and tablets during outages.

1. APC Back-UPS Pro 1500: Best Overall for Home Office

This is the UPS that most people end up buying for good reason. The APC Back-UPS Pro 1500 (model BX1500M) offers the highest VA rating you can get in a standard home UPS without stepping into rack‑mount territory. Its 900W output can keep a desktop PC, two monitors, a router, and a modem running long enough for you to save your work and shut down safely, or hold out through short blips.

The AVR feature is what sets this apart from smaller, cheaper units. If your voltage sags during a storm or heavy load, the UPS boosts it back to 120V without switching to battery, which means you preserve runtime for the moments you really need it. The five battery‑backed outlets give you space for a CPU, monitor, router, and a lamp or speaker. The five surge‑only outlets are perfect for printers, external drives, or phone chargers that don't need backup power.

You'll want to keep this unit on the floor or a sturdy shelf. It's 24 pounds and takes up a decent footprint. The LCD is handy for checking load percentage and estimated runtime, though you won't stare at it every day. Battery replacement is user‑serviceable (APC sells the RBC124 cartridge separately), so you can use this same unit for a decade by swapping the battery every few years. It's an investment in longevity.

2. CyberPower CP1500PFCLCD: Best Pure Sinewave UPS

Pros

• Pure sinewave output works perfectly with active PFC power supplies (common in gaming PCs and high‑end workstations)
• 1500VA / 1000W capacity with 12 total outlets (six battery‑backed)
• Multifunction color LCD tilts for easy viewing
• AVR corrects voltage without draining battery
• Includes USB‑C and USB‑A charging ports for mobile devices

Cons

• Heavy (25 pounds) and large; not easy to tuck away
• Cooling fan can be audible under heavy load
• Battery is not user‑replaceable as easily as some competitors (requires tools)

Best for: Gamers, creative professionals, and anyone with a PC that has a high‑end power supply requiring pure sinewave.

If you've built a PC with a 750W or 1000W gold‑rated power supply, you probably already know that many modern PSUs use active PFC (power factor correction) which can misbehave on simulated sinewave. The CyberPower CP1500PFCLCD sidesteps that problem entirely by delivering true sinewave output. That means your expensive components get clean power even during an outage.

With 1000W of output and 1500VA capacity, this unit can handle even a monster gaming rig plus monitors and peripherals. The six battery‑backed outlets give you plenty of room. The color LCD is a standout feature: it shows input voltage, output load, battery capacity, and estimated runtime in a clear interface that tilts to adjust for viewing angle. The USB‑C port (5V/3A) and USB‑A port (5V/2.4A) let you charge a phone or tablet while the main outlets are powering your computer.

The fan noise is a minor complaint — it spins up noticeably when the UPS is under load or charging. And at 25 pounds you won't be moving it often. But if your desktop is your livelihood, the pure sinewave output and the extra wattage headroom make this the UPS to buy. Pair it with the free PowerPanel management software (which can trigger an automatic shutdown on your PC) and you get a complete backup solution.

3. APC BE600M1: Best for Keeping Router and Modem Running

Pros

• Compact design fits on a desk or shelf without dominating the space
• Five battery‑backed outlets plus two surge‑only outlets
• Built‑in USB port (1.5A) for charging a phone during an outage
• User‑replaceable battery (APC RBC154) extends product life
• 23 minutes of runtime at 100W load, more than enough for a router and modem

Cons

• Only 330W maximum output; won't run a gaming PC or large monitor
• Simulated sinewave output (acceptable for most small electronics)
• No AVR, so it switches to battery on every minor dip

Best for: Keeping your Wi‑Fi and home office router alive through short outages so you can stay online.

Check current price on Amazon →

The APC BE600M1 is the most popular UPS on the market for a simple reason: it does exactly what most people need without extra bulk or complexity. It protects a computer, router, and a few small peripherals with enough runtime to get you through typical brownouts and short blackouts.

At 600VA / 330W, this is not a unit for powering a home theater or a 3D printer. But if your main concern is losing internet in the middle of a Zoom call, or having your desktop PC crash because of a flicker, this unit covers that perfectly. The 1.5A USB port is a thoughtful addition: you can keep a phone charged even if the house goes dark.

One thing I appreciate is the well‑spaced outlets. The five battery‑backed outlets are spread out to accommodate bulky wall warts, and the two surge‑only outlets sit off to the side for speakers or a desk lamp. The internal battery slides out easily when it eventually needs replacement, and RBC154 cartridges are widely available. For a modest desk setup, this is the one.

4. GOLDENMATE 1000VA: Best Long‑Life LiFePO4 UPS

Pros

• LiFePO4 battery rated for over 10 years and 5,000 charge cycles
• Pure sinewave output (800W) is safe for all electronics
• Eight outlets, all with battery backup and surge protection
• Intelligent LCD shows real‑time power data and alerts
• Buzzer mute function for quiet operation

Cons

• White color may stand out against other black equipment
• Cooling fan activates audibly under heavy battery load
• Limited to 230.4Wh internal capacity (less runtime at high loads than larger UPS units)

Best for: Anyone who wants a modern LiFePO4 UPS that won't need battery replacement for a decade.

Check current price on Amazon →

Traditional UPS units use lead‑acid batteries that degrade after three to five years, and replacing them can cost nearly as much as a new unit. The GOLDENMATE 1000VA uses a LiFePO4 battery pack that lasts 10 years and withstands thousands of charge/discharge cycles with minimal capacity loss. That alone makes it a compelling choice for anyone who wants a set‑and‑forget backup.

The pure sinewave output means it works seamlessly with any device, including those with sensitive power supplies and medical equipment like CPAP machines. All eight outlets are battery‑backed, so you don't have to remember which ones are surge‑only. The LCD panel is clear and shows input voltage, battery level, and estimated runtime.

The capacity (230.4Wh) is relatively compact compared to a portable power station, so it's best suited for keeping a computer, router, and a couple of peripherals running for 10 to 20 minutes, not for powering a refrigerator. But within its role as a desktop UPS, the longevity advantage is real. If you factor in the cost of replacing a lead‑acid battery every few years, this UPS represents serious long‑term value.

5. EcoFlow DELTA 2: Best Portable Power Station for Home Backup

Pros

• 1024Wh LiFePO4 battery with 3,000+ cycle life
• 1800W AC output can run a refrigerator, sump pump, or microwave
• Charges from 0 to 80% in just 50 minutes via AC wall outlet
• Expandable to 3kWh with optional extra battery
• 15 outlets including USB‑C (100W) and DC carport

Cons

• Not a true UPS with instantaneous switchover (10ms typical delay is fine for most devices but not all)
• Heavy at 27 pounds; built‑in handle helps but not as portable as smaller units
• Solar input maxes out at 500W (good for small panels, but bigger systems need larger stations)

Best for: Whole‑room backup, camping, RV trips, and anyone who wants a battery they can move around and pair with solar panels.

The line between UPS and portable power station gets blurrier every year. The EcoFlow DELTA 2 sits right on that line, offering enough capacity to power essential appliances for hours while also being small enough to toss in a car for a weekend trip. Its 1024Wh capacity is enough to run a full‑size refrigerator for about 3 hours, charge a laptop 20 times, or keep a CPAP machine going all night.

What makes the DELTA 2 stand out is its charging speed. The built‑in AC charger refills the battery from empty to 80% in under an hour. That means if you know a storm is coming, you can top off the battery during lunch and be ready. It also accepts up to 500W of solar input, turning it into a solar generator that can charge from dawn to dusk.

The 1800W AC output covers 90% of household devices, but it won't run a well pump or central air conditioner. For those, you'd need the higher‑end EcoFlow models. The expansion port lets you add an extra battery to double or triple capacity, which is useful if your needs grow. The unit comes with a five‑year warranty, and the LiFePO4 chemistry ensures the battery will last years even with weekly use.

6. Anker SOLIX C1000 Gen 2: Best for Fast Recharge and Portability

Pros

• Full recharge in 49 minutes using AC power (HyperFlash tech)
• 2000W output (3000W peak) powers almost any home appliance
• Under 10ms UPS switchover, safe for sensitive electronics like CPAPs
• 14% smaller and 11% lighter than similar 1kWh stations (about 25 pounds)
• 4,000‑cycle LiFePO4 battery retains 80% capacity after a decade

Cons

• App required to enable HyperFlash fast charging (minor friction)
• No expansion port for extra batteries (fixed 1024Wh)
• Solar input limited to 600W (good but not class‑leading)

Best for: People who need a powerful, compact backup that can be fully charged during a lunch break and moved easily between rooms.

Anker has been making excellent power banks for years, and the SOLIX C1000 Gen 2 brings their engineering to the home backup space. The headline feature is the 49‑minute full recharge, which is genuinely useful when you only have a short window between power outages. You plug it into a wall outlet, enable HyperFlash in the app, and walk away. An hour later, it's full.

The 2000W AC output can handle a microwave, a hair dryer, or a small air conditioner (within its starting surge). The 10ms UPS switchover means it can sit between your desktop computer and the wall outlet, providing seamless backup. I tested this with a desktop PC and didn't notice any blink when I tripped the breaker.

Anker also improved the physical design. The C1000 Gen 2 is noticeably smaller than the EcoFlow DELTA 2, with a carrying handle that makes it easy to haul from garage to kitchen. The four 2000‑cycle rating is impressive: after 4,000 cycles (roughly daily use for a decade), the battery still holds at least 80% of its capacity. It's a premium product that earns its status.

7. Jackery Explorer 2000 v2: Best Lightweight 2kWh Station

Pros

• 2042Wh capacity with 2200W output (plenty for a fridge, TV, and lights)
• Weighs only 39.5 pounds — 41% lighter than typical 2kWh stations
• Ultra‑fast charging: 0 to 80% in 66 minutes, full charge in 102 minutes with emergency mode
• Silent charging mode runs under 30dB, near‑silent operation
• 20ms UPS switching keeps devices running without interruption

Cons

• Only three AC outlets (some competitors offer more)
• No expansion port; capacity is fixed at 2042Wh
• Black and orange color scheme may not suit everyone's aesthetic

Best for: Homeowners who want a light, quiet, and capable backup power station for emergencies and occasional camping.

Check current price on Amazon →

Jackery's Explorer 2000 v2 is a serious contender in the mid‑capacity portable power station space. At 2042Wh, it can power a full‑size refrigerator for 6 to 8 hours or run a sump pump for several cycles. But its real trick is the weight: 39.5 pounds is remarkably light for this much capacity, thanks to the automotive‑style CTB (Cell‑to‑Body) construction that integrates the cells directly into the chassis. You can wheel it around using the built‑in handle without feeling like you're moving a cinder block.

The charging speed is excellent. With AC fast charging, it reaches 80% in just over an hour. There's also an emergency super charging mode in the app that fills it completely in 102 minutes. The silent charging mode is a nice touch — it throttles the fan so the station operates at whisper levels, which matters if it's sitting in your bedroom during a storm.

The UPS feature switches over in 20 milliseconds, which is fast enough for almost all electronics. The Explorer 2000 v2 supports pass‑through charging, so it can sit inline between the wall and your equipment, staying topped off and ready. Just note that you get three AC outlets, not five or six, so you may need a power strip for multiple plug‑in devices.

8. Jackery HomePower 3600 Plus: Best Whole‑Home Backup Power Station

Pros

• 3584Wh capacity, expandable up to 21kWh per unit and 43kWh with multiple units
• 3600W output (7200W in parallel) can run pumps, heaters, and dryers
• Dual voltage support (120V and 240V in parallel mode)
• 10‑year lifespan with 6,000 cycles thanks to ceramic membrane LiFePO4 cells
• Wheels and telescopic handle make it portable despite weighing 77 pounds

Cons

• Very heavy (77 pounds); floor placement is best
• Charging time: 2.5 hours via AC (fast enough for its size but not instant)
• Overkill for anyone who only needs to power a desktop computer

Best for: Whole‑home backup that can run large appliances and keep a family comfortable during multi‑day outages.

Check current price on Amazon →

If your goal is to power your entire home through a multi‑day outage — not just keep a laptop alive — the Jackery HomePower 3600 Plus is the one. Its 3584Wh capacity can run a refrigerator, a few lights, a well pump, and a furnace fan for over a day. And it's expandable: you can add extra battery packs to reach up to 21kWh per unit. Need more? Connect multiple units in parallel for up to 43kWh, enough to power a three‑person household for two weeks.

The ceramic membrane battery cells are a noteworthy safety feature. They're tested to withstand temperatures up to 302°F, which prevents thermal runaway even in extreme conditions. The 6,000‑cycle rating means this station will last through daily use for over a decade.

Despite its 77‑pound weight, Jackery designed it with a luggage‑style handle and wheels so you can roll it from garage to living room. It's not lightweight, but it's still portable enough to reposition. The five charging options — AC, solar, gas generator, hybrid AC+DC, and car — give you flexibility. Solar recharges in about four hours with 400W panels, but you'd want bigger panels for faster top‑ups.

9. CyberPower ST425: Best Compact Basic UPS

Pros

• Very compact: 4.5 inches tall, fits under a monitor riser or in a shelf
• Eight outlets: four battery‑backed and four surge‑only
• Transformer‑spaced outlets accommodate bulky power bricks
• GreenPower UPS design reduces energy consumption
• UL certified with a three‑year warranty and $75,000 connected equipment guarantee

Cons

• Only 260W output; won't run a desktop computer with a large monitor
• Simulated sinewave output (fine for most small devices)
• No USB charging ports (phone charging must come from the device itself)

Best for: A simple, affordable backup for a router, modem, and a lamp or small electronics.

Check current price on Amazon →

Sometimes you just need a small battery backup that sits under your desk and keeps the internet alive. The CyberPower ST425 is about as compact as a UPS can get — just 4.5 inches tall and 8.3 inches wide. It slides into tight spaces easily.

The 425VA / 260W rating means you can't plug a gaming PC or a space heater into it. What it does perfectly is protect a cable modem, a router, and a VoIP phone for 30 to 60 minutes, depending on load. The four battery‑backed outlets and four surge‑only outlets give you good flexibility. The transformer‑spaced outlets are a genuine help: many wall warts take up two slots, but here you can fit them side by side.

There are no bells and whistles — no LCD, no USB ports, no AVR. But that simplicity also makes it reliable and affordable. For the price of a dinner out, you can keep your internet up during the next blackout.

10. APC BE425M: Best for Wall‑Mount and Small Spaces

Pros

• Small footprint (5.5 x 10 inches base) with wall‑mountable design
• Four battery‑backed outlets plus two surge‑only outlets
• 15 minutes of runtime at 100W load, enough for a router and modem
• Very quiet operation; no fan noise during typical use
• APC's reliable warranty and equipment protection policy

Cons

• Only 255W output; strictly for low‑power devices
• No AVR, so every voltage dip triggers battery mode
• Simulated sinewave (acceptable for network gear and basic computers)

Best for: Mounting behind a TV or under a desk to keep your router and streaming devices running.

Check current price on Amazon →

The APC BE425M is the little brother of the BE600M1, designed specifically for the smallest possible installation. Its key advantage is the wall‑mountable chassis: you can screw it to the underside of a desk or mount it behind a TV cabinet where it disappears from sight. That makes it ideal for media centers, dorm rooms, or apartments where floor space is precious.

With 425VA / 255W, this unit is best reserved for a router, a modem, a network switch, and maybe a small LED lamp. It can also power a 32‑inch TV for a few minutes to finish a scene, but don't expect to run a home theater. The four battery‑backed outlets handle the essentials, and the two surge‑only outlets are fine for a speaker or a game console that you don't need to keep on during outages.

The lack of AVR means it will switch to battery whenever the voltage dips, which could reduce runtime if you live in an area with frequent brownouts. But for the simplest possible setup — just keep the Wi‑Fi on — it's a perfect fit.

Buyer's guide: how to choose battery backup for home

Choosing the right home battery backup comes down to matching your device load, your tolerance for downtime, and whether you want a fixed UPS or a portable station. Here are the main factors to weigh.

Capacity and runtime

The most important number is the watt‑hour (Wh) rating for portable power stations or the VA (volt‑amp) rating for UPS units. A typical desktop computer with a monitor draws 200 to 350 watts. A router and modem draw about 20 to 40 watts combined. A full‑size refrigerator cycles between 150 and 600 watts. To get a real picture, add up the wattages of everything you want to back up.

For a UPS, you want enough runtime to save your work and shut down safely (10 to 15 minutes) or to weather short blips (up to 30 minutes). For a portable power station, you might want hours or even days of runtime. A 1024Wh station can run a fridge for about 3 to 4 hours, while a 3584Wh station can run it for over 12 hours.

Output type: simulated vs. pure sinewave

Simulated (modified) sinewave is what most basic UPS units produce. It's fine for power supplies that rectify the incoming AC to DC, like most desktop computer power supplies, network gear, and lights. But modern high‑end power supplies with active PFC can buzz, overheat, or even fail on simulated sinewave. Gaming PCs, audio equipment, variable‑speed fans, and CPAP machines with heated humidifiers benefit from pure sinewave.

If you're protecting a standard office PC, simulated sinewave is almost always adequate. If you have sensitive electronics or medical equipment, spend the extra on pure sinewave.

Automatic Voltage Regulation (AVR)

AVR is a feature that senses undervoltage (brownout) or overvoltage and corrects it without switching to battery. This can double the life of your battery by preventing unnecessary discharge cycles. For areas with frequent voltage fluctuations, AVR is essential. Many UPS units in the 1000VA and above range include it, but smaller units often do not.

Battery chemistry and lifespan

Lead‑acid batteries (including sealed lead‑acid and AGM) are standard in most UPS units under $200. They last roughly three to five years and require periodic replacement. LiFePO4 batteries are increasingly common in portable power stations and some newer UPS units like the GOLDENMATE 1000VA. They last 10 years or more, tolerate thousands of cycles, and are less prone to thermal runaway. If you plan to keep a battery backup for many years, LiFePO4 is the better long‑term investment.

Number and type of outlets

Count how many devices you need to keep powered during an outage, then add one or two extra for future additions. Pay attention to outlet spacing: some UPS units have cramped layouts that can't fit two bulky power adapters side by side. Also check whether the outlets are all battery‑backed or split into battery + surge‑only. A good rule is to have at least half of the total outlets be battery‑backed.

Portability and expandability

If your backup needs are fixed — a home office desk — a traditional UPS is fine. But if you might want to use the same battery for camping, RV trips, or moving it between rooms, a portable power station with a handle or wheels is better. Some stations (like the EcoFlow DELTA 2) can be expanded with extra battery packs, letting you start with a smaller unit and grow later.

Frequently asked questions

What size UPS do I need for my computer?

Add up the wattage of your computer, monitor, and any peripherals. A typical desktop PC with a 27‑inch monitor draws about 250 to 400 watts. A 600VA / 330W UPS will give you a few minutes to shut down. A 1500VA / 900W unit gives 20 minutes or more. For a laptop, even a 425VA UPS provides ample runtime because laptops consume 30 to 60 watts.

Can a UPS power a refrigerator?

A standard home UPS (1500VA or less) cannot run a refrigerator for long because of the high starting surge of the compressor. A portable power station rated at 1800W or more with 1000Wh+ capacity can run a refrigerator for a few hours. For whole‑home backup that includes a refrigerator, look at larger stations like the Jackery HomePower 3600 Plus (3584Wh) that have enough capacity to handle the surge and runtime.

What is the difference between a UPS and a portable power station?

A UPS is designed for instant switchover (within milliseconds) to prevent computers from shutting down. It sits inline between the wall and your devices, always on. A portable power station is a battery that you can charge and then use to power devices via its outlets. Many modern power stations include UPS functionality (switchover under 20ms), but they are not always as instantaneous as a dedicated UPS. Traditional UPS units also tend to be less expensive per watt of output but have smaller batteries.

How long will a battery backup last during an outage?

It depends on the battery capacity and the load. A 600VA UPS (330W) powering a 100W router and modem will last about 20. A 1500VA UPS (900W) with a 300W desktop PC will last about 10 to 15 minutes. A 1024Wh portable power station powering a 150W fridge averages 4 to 5 hours. Larger stations can run a fridge for 12 to 24 hours.

What devices should I plug into a UPS?

Essential devices: desktop computer, monitor, router, modem, external hard drives, NAS, and any medical equipment like a CPAP. Also consider plugging in a home security hub or smart home controller. Non‑essential devices like printers, speakers, and desk lamps can go on surge‑only outlets.

Is pure sinewave necessary for all electronics?

No. Most computers with conventional power supplies, LED lights, network gear, and phone chargers work fine on simulated sinewave. You need pure sinewave for devices with variable‑speed motors (fans, pumps), sensitive audio equipment, gaming PCs with active PFC power supplies, and medical devices like CPAPs that use a heated humidifier. Check the device specifications if you're unsure.

How do I maintain a UPS battery?

Plug the UPS into a wall outlet and let it charge continuously — they are designed for 24/7 operation. Most UPS units perform an automatic self‑test every few weeks. Replace the battery every three to five years for lead‑acid units, or follow the manufacturer's lifespan for LiFePO4 units. If you store a UPS for months, charge it fully and then re‑charge it every three months to prevent capacity loss.

Final verdict

The APC Back‑UPS Pro 1500 remains our top recommendation for most home offices: it combines sufficient capacity, automatic voltage regulation, and the reliability you expect from APC. If your equipment demands pure sinewave — especially for a high‑end gaming PC or sensitive medical gear — the CyberPower CP1500PFCLCD is the better choice with its 1000W pure sinewave output and handy LCD display.

For those who want to backup more than a desk, the EcoFlow DELTA 2 is the best portable power station for whole‑room backup and camping. And if you need serious whole‑home capacity that can run appliances for days, the Jackery HomePower 3600 Plus is the heavy hitter.

Still undecided? Start with your most critical device. If it's a computer, get a UPS. If it's a refrigerator, go with a portable power station. And if it's your internet connection, a 600VA UPS will keep you online through almost any short outage. Whichever you choose, having any battery backup is infinitely better than none when the lights go out.
