Best for Businesses: APC UPS 2200VA Smart-UPS with SmartConnect

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.

When the worst happens and power goes out, flipping the Aeiusny on is as simple as moving a single switch. Then you can keep up with local news for up to four hours on a 32-inch TV or eight hours on a 13-inch laptop.

Recharging the travel Aeiusny is as easy as using the included AC charging cable. A car-charging cable is also included for emergencies. As an added bonus, a front lamp helps you see in the dark. 

Best for Networking and Other Devices: CyberPower CP800AVR

What We Like
  • Widely-spaced outlets for increased convenience

  • Easy to manage using desktop software

What We Don't Like
  • 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.

Best Value: AmazonBasics Standby UPS 800VA

What We Like
  • Compact design

  • One-button operation

What We Don't Like
  • 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.

Best for Home Use: Tripp Lite AVR750U

What We Like
  • Space-saving design

  • Backup runtime of up to 42 minutes (for one PC)

What We Don't Like
  • 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.

What to Look for in an Uninterrupted Power Supply

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.
