The best uninterruptible power supplies (UPS) will be able to support your devices, especially desktops, even when there is a blackout in your area! For that reason, looking into the battery life and device support will be two of the most important factors when looking for your new UPS. Other honorable mentions for factors include compatibility and portability. If looking for more power than a UPS can provide, maybe a portable generator is a better option to suit your needs.
Battery run time may be shorter than you expect with some of the longer-running models lasting through the night, and others lasting around a half-hour. The amount of devices each device can accommodate varies as well. Some machines can power up to two devices, while others can reach a maximum of ten. Before purchasing, knowing how many outlets you intend to plug in will be critical. While the backup time for the Tripp Lite AVR750U UPS Battery Backup at Amazon, is short, it can support up to six crucial devices, and an additional six can be supported as well, making this UPS perfect for multiple gadgets that need support for a limited time. The APC UPS 2200VA Smart-UPS with SmartConnect, at B&H Photo Video, is perfect for people who would prefer a more lengthy battery life of over five hours and extras like cloud storage connectivity.

Tiltable LCD panel displays real-time status information
Data Line protection
Backup runtime (with full load) isn't exactly great
Undeniably one of the best UPS systems available in the market today, CyberPower's CP1500PFCLCD boasts a laundry list of features. Having a power output of 1000 watts, it uses Active Power Factor Correction (PFC) to deliver clean Sinewave energy. This is complemented by Automatic Voltage Regulation (AVR), which automatically corrects power fluctuations to protect the connected equipment against hazards like voltage spikes and brownouts.
The line-interactive Uninterruptible Power Supply includes a total of twelve surge-protected 5-15R power outlets, of which six come with battery backup and are meant for critical devices like computers. One of the most useful features of CyberPower CP1500PFCLCD is its multifunction control panel. Located on the front of the UPS, it sports a color LCD that displays a variety of useful information (e.g. battery capacity, load level) and lets you easily monitor the device's operation. Among other notable features are two USB (one Type-A and one Type-C) ports for charging mobile devices, and remote management via a companion software program.
Extensive battery life
In business, there’s no room for data loss, so it’s important to have a backup plan. The APC UPS 2200VA Smart-UPS with SmartConnect is just that. As one of the first cloud-enabled APC UPS for distributed IT systems, it's an ideal choice for businesses. IT professionals can access the hardware through a secure portal and view its status, update the firmware, and maximize performance.
Installing the hardware is a snap. Once the system is unboxed and plugged in, it connects to the network via a dedicated ethernet port. It is then automatically registered on the SmartConnect Web Portal and registered to the business. The web interface adds clear notifications to keep system administrators aware of the APC’s status. There’s also support for PowerChute software which safely shuts down the system during extended power outages. This ensures there’s no data corruption by an accidental shutdown.
Running at an average of 100 watts, the APC unit can provide over five hours and 30 minutes of battery backup. That power is available for up to 10 pieces of hardware with 10 AC outlets on the rear.
Widely-spaced outlets for increased convenience
Easy to manage using desktop software
A bit too bulky
Although UPS systems have been associated largely with PCs, they are also used to protect a wide range of additional peripherals, including everything from routers to printers. If you need an Uninterruptible Power Supply for a similar use case, get CyberPower’s CP800AVR. As the name suggests, it utilizes Automatic Voltage Regulation (AVR) to correct power fluctuations and safeguard connected equipment against hazards like voltage surges and blackouts.
Based on line-interactive topology, the UPS includes eight 5-15R power outlets. While all of these outlets have surge protection, four offer battery backup as well. It comes with a patented “GreenPower UPS” technology that not only improves operating efficiency, but also reduces heat buildup. Backed by a three-year warranty, CyberPower CP800AVR features a USB port and a serial port, which can be used to connect the UPS to a computer and monitor/control its functions via dedicated companion software.
No Auto-restart (after line power is restored)
AmazonBasics-branded products have a reputation for great value, and the Standby UPS 800VA is no exception. The modestly priced Uninterruptible Power Supply does a solid job of securing the connected equipment (e.g. PCs, IoT devices) against power fluctuations , brownouts and the like. It has a power output of 450 watts and uses a sealed, maintenance-free lead-acid battery.
The UPS system comes with twelve surge-protected 5-15R power outlets, and six of these offer battery backup (recommended for essential devices only). It's also extremely easy to use, since all the primary functions (e.g. Power On/Off, Alarm On/Off) can be controlled with just a single button. A built-in USB port lets you connect the unit to a computer for managing the former's settings through a companion software program. AmazonBasics Standby UPS 800VA weighs around 9.2 lbs and is backed by a one-year limited warranty.
Backup runtime of up to 42 minutes (for one PC)
Unintuitive Java-based management software
Reliable and loaded with features, Tripp Lite’s AVR750U is easily one of the best Uninterruptible Power Supplies you can get for home use. It uses Automatic Voltage Regulation (AVR) to correct both high- and low-voltage conditions, thus protecting the connected equipment against power spikes, brownouts, and line noise.
The line-interactive UPS system comes with a total of twelve 5-15R power outlets, all featuring surge protection. Six of these outlets offer battery backup and are intended for critical devices such as PCs, while the rest can be used to connect non-crucial hardware like speakers. The UPS includes an unobtrusive alarm that only sounds when absolutely needed (e.g. low battery, overload). An integrated USB port allows the Tripp Lite to communicate with a computer, and you can use the companion desktop software to configure functions like unattended file saves and automatic system shutdown in case of power outages. To add some extra assurance to your insurance, the UPS is backed by a three-year limited warranty.
Easy to use
Not that useful for large equipment
If you think all feature-packed UPS systems cost hundreds of dollars, APC's BE600M1 is here to prove you wrong. Despite its affordable price tag, this model comes fully loaded. The Uninterruptible Power Supply has a power output of 330 watts and is ideal for small devices such as routers, cable/satellite boxes, and Internet of Things (IoT) equipment. It comes with seven 5-15R power outlets that all provide surge protection, and five of these offer battery backup as well. There's even a USB Type-A port (with 1.5A output) for charging smartphones, and a secondary data port that lets you connect the UPS with a PC for remote configuration via a companion software program. APC BE600M1 is extremely easy to use, and features just one button that can not only be used to power it On/Off, but also for silencing the alarms. It uses a sealed, maintenance-free battery and is backed by a three-year warranty.
Compatibility - When buying a UPS, the most important factor to consider is its compatibility with the power supply. Before hooking anything up, check what your devices require and make sure there’s a match.
On-battery runtime - Generally, you don’t need a UPS to last too long but it should be sufficient to start a standby power source or properly shut down the protected equipment. Some run for just a few minutes, while others will provide power all night long. Depending on your needs, make sure the on-battery runtime is ample.
Device support - How many devices will you need to connect to your UPS? Some can accommodate as many as 10 devices, while others top out at just two.
Portability - Some UPS devices are crafted for home or business use, while others are built for travel and the outdoors. If you’ll need to take your device with you, you’ll want something with a more portable design that can fit in a handbag easily. You might even want a solar charging port so that you aren’t entirely dependent on electricity.
