A battery’s sine-wave inverter turns its direct current (DC) power into alternating current (AC) power, which you need to power most devices.

Pure sine-wave inverter: We required this feature in our upgrade-pick contenders and preferred it in all other models.

Since AVR is available without a huge price premium, it’s a sensible feature that can help you get the most from a UPS in the long term. It also provides more-reliable power to sensitive gear such as hard drives. This reduces wear and tear, especially if you live somewhere with frequent brownouts, and prolongs the overall life of the battery. With AVR, when power from a wall outlet dips or surges briefly outside of a specified range, a small transformer in the UPS acts like a buffer to compensate without relying on the battery the UPS switches to battery power only when the transformer can’t handle the variation. AVR, also called line-interactive topology, is a more advanced form of power management than the type that less-expensive models use.

Automatic voltage regulation (AVR): We required our upgrade-pick contenders to have AVR, and we strongly preferred it in all other models.

Measured surge protection: 402.8 let-through volts.

Measured run time with a 300 W (modem, router, PC, and hard drive) load: 6 minutes.

Measured run time with a 20 W (modem and router) load: 1.5 hours.

Plus, Amazon offers only a one-year warranty on its UPS models, in contrast to the three-year warranties that brand-name companies provide. That should be fine in most cases, but it’s harder on the battery, and you shouldn’t use it for sensitive AV gear or medical equipment. Unlike our other picks, this less expensive model uses standby power management instead of automatic voltage regulation (AVR). Its maximum output is on the lower side (we measured up to 470 W in our testing), but that should be plenty of power for the six battery-backed outlets to support basics such as home Wi-Fi gear.

If you’re on a tight budget, the Amazon Basics Standby UPS 800VA is an affordable UPS with the battery and run time of a more expensive model: It can keep a typical router and modem running for up to one and a half hours. Measured surge protection: 593.2 let-through volts.Measured run time with a 300 W (modem, router, PC, and hard drive) load: 21 minutes.Lastly, its backlit screen provides helpful information such as the remaining battery life and the total wattage of the devices plugged into the unit. Because it has a pure sine-wave inverter, its power is as smooth as that of a standard wall outlet, making it safe and reliable for even sensitive equipment such as a CPAP machine.

Roughly the size and shape of a small PC tower, it has 10 outlets in total, six of which it backs up with the battery, and it adds two USB ports (one USB-A and one USB-C) for charging small devices without the need for an extra power adapter. Like our top pick, it can keep the average modem and router running for up to four hours, giving you more than enough time to save your work and wait for the blackout to end. If you need to provide power to more (or larger) devices at your computer workstation during an outage, it can deliver up to 847 W-we had trouble finding home-office gear powerful enough to overload it in our testing. The APC BR1500MS2 is the most expensive UPS we recommend for most homes or small offices, but it offers a lot of value in the extra features it includes. Measured surge protection: 540.4 let-through volts.Measured run time with a 300 W (modem, router, PC, and hard drive) load: 17 minutes.Measured run time with a 20 W (modem and router) load: 4 hours.Five of its 10 outlets are backed up by a battery, and its compact shape-about the size of a three-ring binder-and its 6-foot cord make it relatively easy to stow under a desk or nightstand.

It requires no setup aside from plugging it in, and it includes automatic voltage regulation-an important feature that some cheaper models lack. In our tests, it provided enough power to keep a household broadband modem and Wi-Fi router running for four hours, which means you can stay online while the power is off and get in touch with emergency services, follow news and weather changes, or just pass the time on your favorite websites. The CyberPower CP900AVR will cover the basics for most people during common, short-term blackouts.
