Losing power is never fun, but it can also seriously mess with your electronics, especially if you don’t have a battery backup on-hand. Computers, external hard drives, home Wi-Fi networks, and more all feel the negative effects of an outage. So, it’s important to create a plan of action to keep your home or your business, or both, running during these possible future blackouts. One important part of your plan should be to consider the best battery backups (uninterruptible power supply, or UPS), which will automatically take over when the power drops or goes out entirely.

But there’s no one solution that’s perfect for everyone. Some might need a more powerful and versatile solution—particularly if you’re looking to back up the equipment in your business. Or maybe you have computers and laptops that are particularly sensitive. And you’ll find that UPS models have a broad price range—you can buy one for under $100 or spend thousands of dollars. 

To help you narrow those choices, we’ve put together a list of the best 5 UPS models currently available.

Even if you’re not prone to power outages, many UPS models also include surge protection features. An automatic voltage regulator smoothes over brownouts and spikes without needing to change your battery. It’s one of a number of capabilities you’ll want to look for in the best battery backups.

How we chose the best battery backups

For the majority of the UPS models in this guide, we focused on the home user, which is why we selected units that were less than $300. However, for one, Best UPS for business, we selected a more expensive model, since most small business owners are likely to pay more for a more robust UPS that can handle more machines. 

Next, we prioritized UPS options that output as a clean sine waveform, instead of a simulated sine waveform: This feature is important for more sensitive computers, like gaming systems, and audio equipment. 

We also considered a number of other features that we considered important—for instance, we looked for UPS models that included surge protection features, like line interactive topology, which uses an automatic voltage regulator to normalize any dips or spikes in power in active (or non-battery backup) mode. We also considered other features: How many outputs did the UPS have? How many outlets were both battery-and-surge-protected outlets? How many outlets had only surge protection? Plus, we considered USB ports, the length of the power cord. These details can sound pedantic, but they can make a huge difference in day-to-day use.

What to consider when buying the best battery backups

If you’re looking to buy a UPS, you’ll find that there’s a rather large range in prices—from less than $100 to more than one thousand dollars. So, how do you choose? Use the following guide to help you make your decision. Here are some factors to consider before making your purchase:


When you’re looking to buy an uninterruptible power supply, or UPS, which is a device that will not only provide power to various devices, like a laptop or wireless router, but it also serves as a surge protector. Depending on how powerful your UPS is, you can have it provide battery backup power to many different devices. However, you’ll need to make sure that your supply has enough output power for the job. In general, the best battery backups can output at least 400W.

Sine wave inverter

UPS models include a number of different features, but you’ll want to focus on a couple, depending on what you want to back up. A sine-wave inverter allows a UPS to produce a clean sine waveform, which is the best type for power output. In contrast, some inexpensive models output a simulated sine waveform, which can be problematic for some higher-end gaming laptops and audio gear. Another key feature is to look for line interactive topology, which in some UPS models, use an automatic voltage regulator to compensate for small dips and spikes in the active power coming into your house. So, this feature acts as surge protection for your computers and system.

Endurance and outlets

A unit’s longevity depends on how powerful your UPS is, as well as how it’s configured. For budget or low-end UPS models, you’ll only be able to power devices that aren’t as powerful. Also, lower-end UPS models won’t let you run your computers and other gear as long. (This is called “run-time” and some manufacturers include this information on the product sections of their websites.) Be sure to research how much power you’ll need to run your devices in case of a blackout.

Most UPS models include a number of outlets that include both battery backup and surge protection and outlets that only have surge protection. Be sure you factor that in when making your battery backup plan.

Device compatibility

There are some types of products that you won’t be able to run—such as a refrigerator or microwave, which would be too taxing on the UPS. Also, there are some smaller products that just draw too much power. Hairdryers fit that description. 

It’s also important to remember that a UPS isn’t meant to take the place of a home generator, which has a more robust power capacity. But for many consumer electronic devices, even monitors and power PCs, a UPS should give you the ability to run them, at least for a short amount of time. (Again, be sure to study the features and specs of the USP models you’d like to purchase to see if they will back up your system effectively.)

The best battery backups: Reviews & Recommendations

Losing power is stressful—don’t let your offline router and computer add to it. The best battery backups can give you peace of mind that your electronics aren’t in the dark while you call the electric company. Here are our choices.

It also has a lot of power, for hooking up many devices, including your network, into the system. You get ten outlets, eight of which are both power-backed and surge-protected. The UPS also has both line interactive topology (via an automatic voltage regulator) and uses a clean pure sine wave form for output, which makes it compatible with most any computer or audio gear.  

Best budget: Tripp Lite AVR750U 750VA UPS

Tripp Lite


Why it made the cut:  A very small investment provides solid backup to protect your pricier devices.


  • Power/Watts: 750AV/450W
  • Battery & Surge Protected: 6 outlets
  • Surge Protected Only: 6 outlets


  • Inexpensive
  • 12 outlets (6 with both battery backup and surge protection
  • Includes line interactive topology, with automatic voltage regulator


  • Simulated sine wave form (in backup mode)

If you’re on a tight budget, you might be tempted to skip on buying a UPS for your gear. However, that would leave you vulnerable to power outages. Instead of foregoing a UPS, consider a budget-priced model, like this one from Tripp. The Tripp Lite AVR750U 750VA UPS can generate 450 watts, and has 12 outlets—6 battery & surge protected and 6 surge protected only.

It also provides you with line interactive topology, with automatic voltage regulator—for regulating dips and spikes in your active system without needing to switch to battery power. According to the specs, the line-interactive battery backup can correct for “brownouts and over voltages from 83V to 147V.” 

At this price, though, it should be a surprise that it uses a simulated sine waveform (in backup mode) and may not perform adequately with sensitive gear. However, it does include a USB port, has TEL/DSL protection and it can mount to the wall.


Q: What is a UPS for a computer?

A UPS stands for an “uninterruptible power supply” and is essentially a battery back for your computer or other devices and network should you lose power. If the power dies, a quality UPS will kick in automatically.

Q: Does a UPS offer surge protection?

Most UPS models offer line interactive topology via an automatic voltage regulator to compensate for small dips and spikes in the active power coming into your house. Even if a model does offer it, however, it may not provide it to every outlet, so make sure to check the listing or the manual before you plug in.

Q: How long can I run my computer or devices on a UPS?

It depends on the system, computer and your UPS: If you’re only using a computer, you might be able to run it for 45 minutes. But if you add a monitor and an external hard drive to that, your UPS might only last for 10 minutes. Some of the UPS manufacturers include some runtime figures that might be useful to get an idea of how much time you have to run your devices.

Finals thoughts on the best battery backups

Today, many of us are not only buying more computer gear and mobile devices for our homes, but many of us are also working more from home in hybrid-work situations. That’s why it’s more important than ever that you have a backup plan for your computers and other electronic devices. And that plan should include seeking out the best battery backups.
