How We Picked

These days making sure that your essential appliances and electronic devices receive consistent power is more important than ever. While a complete power outage is certainly a cause for concern, even a brownout or a momentary power surge can still damage electronics and lead to a loss of critical data.

Connecting your computer and other essential electronics to an uninterrupted power supply with built-in surge protection is a relatively inexpensive way to preserve high-value electronics. More commonly referred to as a UPS, these sophisticated devices pay for themselves with peace of mind.

Of course, there are a few things that go into finding the best-uninterrupted power supply for your home or office. Throughout the review process, we tried to keep our eyes out for key features and thoughtful engineering.

Wattage Capacity

Most of the best UPS systems use Watts as the unit of measure. To determine the capacity you need, you will have to check the wattage rating of each device you want to connect. You can find this in the owner’s manual or stamped into the back or bottom.

For our review process, we tried to target UPS systems that had at least an 800 Watt load capacity. This should be enough to let you safely power down a typical home or small office during a power outage. Though we did make sure to include a few lower wattage budget models that you might want to place in a child’s bedroom. Some units are designed to handle more than just a single office, with the wattage requirements and sophisticated software to support a server room or similar IT environment.

AVR

Automatic Voltage Regulation is increasingly popular for protecting today’s sophisticated, yet often sensitive electronic devices. A brownout or a power surge that manages to make it from the external power grid to a plugged-in laptop, or server could cause severe damage as well as potential data loss.

AVR essentially acts as a buffer against these problems. We tried to look for it, or something similar in the UPS systems we reviewed.

Connectivity And Management Software

A lot of the best UPS systems on the market today have some type of management software. This lets you check the status of your system at a glance, or make any necessary alterations. Remote access via a cloud-enabled system was also something we tried to keep an eye out for when it comes to units with a higher price tag.

Buyers Guide

Right off the bat, the temptation is to assume that an uninterrupted power supply system is only necessary for power outages. Sure, they are an absolute life-saver for a short-to-mid-term blackout. However, that’s not the only time you might consider yourself blessed to have a UPS in your home or office.

On the face of it, an uninterrupted power supply is a sophisticated battery backup system that is designed to power your essential electronics during a power outage. They play a critical role in preventing data loss or the potential hardware stress that can sometimes occur during a hard shutdown.

At the same time, a quality UPS also acts as a surge protector. This can be especially handy if a local power surge affects your area, which can cause short-term damage or reduce an electronic device’s long-term lifespan.

Beyond surges and total blackouts, there are a few other scenarios where a UPS can come in handy. Especially, if for powering essential office electronics to maintain the normal flow of operations. This includes things like:

A Brownout is where there is a prolonged drop in voltage. Some brownouts are related to weather, though with our aging electrical infrastructure it could be a failure in part of the electrical grid. Sometimes a brownout is an early warning sign of a blackout. Being able to keep essential electronics powered up can help you prepare for total power loss. Especially if you need to do things like backup crucial data.

A Voltage Sag is like a miniature brownout. The problem here is that they sometimes occur in a short series, which can potentially damage certain types of electrical equipment.

An Over Voltage Event is like a mini-surge that lasts longer than normal and can damage sensitive electronics. A UPS with a sophisticated surge protection feature helps buffer the voltage to keep electronic devices safe.

Line Noise can disrupt or potentially degrade the performance of a circuit.

Frequency Variation can be a problem if you are running off a generator and the power frequency fluctuates. Here again, the UPS acts as a buffer to maintain a consistent frequency level.

Different Topologies Of UPS System

At first glance, UPS systems pretty much all do the same thing. They act as a battery backup as well as a buffer against surges and other electrical events that might otherwise travel from the grid to your sensitive electronic devices.

However, different “Topologies” or types of UPS are engineered with features that cater better to specific needs.

A Standby UPS – Sometimes referred to as an Offline UPS, it essentially draws current from a standard electrical outlet and switches over to the power from the internal battery backup the instant it detects a power failure. This is arguably the most common type of UPS system and one you might often find in an individual office setting to provide backup power for a computer, printer or other electronic devices.
is the most common type of UPS found in a computer or office supply store. It draws current from the AC outlet and switches to the battery within a few milliseconds after detecting a power failure.

A Line-Interactive UPS – This type of system uses AVR or Automatic Voltage Regulation to effectively correct abnormalities in voltage without having to immediately resort to the reserve battery power. It does this through a special type of transformer that either lowers or boosts the voltage as needed. A

Line-Interactive UPS is essentially a buffer to protect your sensitive electronics from events that affect the power grid or the internal wiring of a building. They are particularly handy for protecting Network-Attached Storage devices and modest-size data storage servers.

A Double Conversion On-Line UPS – It shares a lot of features and functionality with a Standby UPS. One of the key differences is that it inverts the AC power to reduce heat output and improve efficiency.

Wattage Load Capacity

For a UPS system to run properly it must have the capacity to meet the power demands of every electronic device that’s connected to it. This is typically expressed in a wattage rating, that you can then correspond to the total overall load of the devices you plug into it.

To accurately calculate your load needs, you will have to add up the wattage of every single device you want to connect to the UPS. You can usually find this information in the owner’s manual. Though a lot of appliances and electronic devices will have some sort of plate stamped or printed on them with wattage and other key specs.

Once you have your load calculated you start filtering through the UPS systems that are closest to your needs. Though you shouldn’t push it right up to the limit. It’s a good idea to target a UPS system that is rated at least 10% higher than you need. Especially if you’re thinking of upgrading or updating your devices a year or two down the road.

To make your UPS run properly, your UPS has to be large enough to support all of the equipment plugged into it. You will need to find the UPS capacity. Capacity is how much power a UPS system can provide (measured in Watts). The higher the capacity, the more electronic equipment, and devices it can support. To find the UPS capacity, you will need to calculate the load. The Load is the combined amount of power each of the devices uses.

To identify the load, make an equipment list, including the total watts each piece of equipment requires to run properly. Include all of the devices the UPS will need to support. If a piece of equipment has a redundant power supply, only count the wattage of ONE power supply.

If you are unsure how many watts your equipment requires, consult the manufacturer or power supply specifications in the user manual.

The Number Of Outlets

A quality UPS system is not the sort of thing you want to daisy chain like Christmas lights. You really should have 1 outlet per power cord. Plugging in a power strip or a splitter is a bad idea and could impact performance when you need it most. If you plan to plug three devices in the UPS system, you need to find one that has at least three outlets.

Determining Runtime Needs

Since the UPS is essentially a sophisticated battery backup system, it has a finite capacity. As time goes on, the current stored inside the battery will gradually start to dwindle. The “Runtime” is essentially the number of minutes of consistent power the UPS system can support from a full charge.

It helps to take a moment to do a little thought experiment on how long you’ll want the power to your essential electronics. If you need time to save essential data on your laptop or print another copy of a business proposal during a short-term blackout, you might be fine with a shorter runtime. If you want to keep working for hours after a power outage, or you simply want enough power to finish watching a movie on a stormy day, while you wait for the power company to restore the lines, then you might prioritize a longer runtime.

It’s important to remember that the runtime will be influenced by the wattage of each device. The lower the wattage demand, the more minutes of runtime you will get from the batteries.

Frequently Asked Questions

Q: Do I Need A UPS With A Sine Wave Or Simulated Sine Wave Output?

A: The power grid delivers AC power in a sinewave. When everything is operating normally, you UPS is simply passing this sine wave on to all the connected electronic devices. In the event of a power outage or brownout, the UPS will produce a sine wave or simulate a sine wave to your electronics.

With a simulated sine wave, there is sometimes a minor power gap during each cycle. Some appliances like refrigerators, microwaves, and air compressors with motors that run on AC electricity can be damaged by a simulated sine wave.

Q: What Is A Hot-Swappable Battery?

A: A UPS with hot-swappable batteries allows you to exchange additional backup batteries without having to shut the unit down. They are especially nice for times when your area suffers a prolonged power outage, and you want to continue working or using some essential electronics.

Q: What Is The Difference Between A Rack-Mounted UPS and a Tower?

A: With most UPS manufacturers a rack-mounted or tower UPS tends to have the same basic specifications and features. The rack-mounted version tends to be more popular for a UPS device that’s meant to support a server or a Network-Attached Storage device. If you are just looking to back up a single office computer, a work station or a home theater, then a tower is probably easier to work with.

Q: Why Do Some UPS Devices Only Have Half The Outlets Connected To The Battery Backup?

A: UPS manufacturers recognize that part of the value of the system is acting as a surge protector. At the same time, when there’s a power outage have a ton of devices plugged into the battery backup outlets. The last thing you want is the lamp in the corner or a digital picture frame on the wall draining current and reducing the overall runtime available to safely shut down your workstation computer.

Q: Should I Max Out The Load Capacity?

A: While each UPS is rated for specific maximum load capacity, it’s also best not to push it to the max. The general rule of thumb is to only ask it to deliver 80% of the maximum load capacity at any one time. So, if you have a UPS that’s rated for 1,000-Watt maximum load capacity, you should try to keep the wattage demand of the devices on the battery backup side to around 800 Watts.

Conclusion

Investing in a UPS system makes a lot of sense beyond just buying you some extra time to save your work or finish watching a movie when the power goes out. A quality UPS system also helps protect your investment in the electronic devices and data it supports. In a worst-case scenario, a single surge or brownout event could cause thousands if not tens of thousands of dollars in damage. Taken in this light even a high-priced UPS system pays for itself in short order.

Finding the best UPS system for you still will require a little filtering and some basic mathematics. Right off the bat, you will want to double-check the wattage rating for each device you want to connect. This will give you a target range for load capacity to help weed out the field.

If you aren’t going to support a server or NAS box, then you can just stick to a “Standby UPS” If you do need to support some type of server environment, then you might want to prioritize a Line-Interactive or a Double conversion topology. In the case of a server support UPS, you might want to also look for a rack-mounted UPS rather than a tower.

At that point, you can start to dial in special features like management software and price. You should also keep an eye out for warranty coverage, as well as taking a look at how much insurance coverage the manufacturer offers for connected devices.
