A1000VA UPS might be able to power a small office computer for around sevenminutes. We measured a peak power output of 470 W, as it allowed us to connect an assortment of eight halogen bulbs and two lamps to its battery-backed outlets before it tapped out a few seconds later. This saves you the trouble of racing into the office to save your data and eliminates the opportunity for human error. It costs around twice the price of a model like the CP900AVR, but its peak power output is higher than that of nearly every other UPS weve tested, it can keep a home Wi-Fi network powered for a few minutes longer, and it has an LCD screen for you to closely monitor output, battery life, and other variables. The Amazon Basics Standby UPS 600VA has mediocre battery capacity: In our testing, we measured a 30-minute run time at a 20 W load, and three minutes at a 300 W load. We also added a few models from Amazon Basics to our list because its a prominent option when youre shopping online. Businesses come in a range of shapes and sizes, and so too do the UPS devices that support them. We tested six new NAS devices and found that the Synology DS220+ is the best for most home users because of its performance, versatile software, and good price. With a one-year warranty, you have little wiggle room, so if you do choose this model, make sure to test it out within that window to confirm that it worksand continue to test the battery periodically by unplugging the UPS from the wall and letting it run on its battery. Although most Americans recycle plastic, metal, paper, and cardboard on a regular basis, less than half recycle their used batteries and other electronic waste. When we inundated the BR1500MS2 with 5,000-volt surges, it was able to block all but 593.2 volts. But because it has automatic voltage regulation (AVR), this UPS doesnt need to transition from wall-outlet power to battery power as often as models lacking this feature. A 350-VA unit costs about $50 and should power a router for almost two hours, depending on the routers wattage. The onboard battery and surge protector helps smooth out the power flow the reduce the chance of damaging to your equipment. Our journalists combine independent research with (occasionally) over-the-top testing to save people time, energy and money when making buying decisions. If the battery in a UPS is drained too frequently due to it supplying a heavier load than expected, then its total capacity will begin to suffer, and youll need to replace the battery sooner. The CP900AVR has a modified sine-wave inverter, so it produces a slightly choppier electrical waveform than what you can get from the pure sine-wave inverters found in more expensive models, which are better for powering sensitive equipment. If youre just running one computer, then you might get away with a smaller one. We started by considering more than 100 models from three leading companies: APC, CyberPower, and Tripp Lite. Do not everever, everplug a UPS into a surge protector, or vice versa. The CyberPower CP900AVR offers premium features that you typically find in units costing twice as much.

Many manufacturers, such as Riello UPS,APC UPS,Vertiv UPS and Eaton UPS,will provide an estimate of how long the UPS can run at full capacity. A small, inexpensive UPS is great for anyone who wants their home Wi-Fi and internet to stay online during short power outages or brownouts. The CyberPower CP1000PFCLCD, a former pick, uses a pure sine-wave inverter to create a smooth sine wave when running on battery power. We can supply small UPS (Uninterruptible Power Supplies) to support a home office, to a larger UPS to keep the central server running or a diesel generator tomanufacturing equipment. 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. We are no longer supporting IE (Internet Explorer). In our testing, we ran out of 10-, 50-, and 100-watt appliances trying to reach the BR1500MS2s peak power output, so we ended up putting it to the ultimate test by plugging in a hair dryerdont try this at home, since a UPS is not designed for use with heat-producing devicesafter which we finally measured a maximum output of 847 watts. If the cord on your UPS isnt long enough, youre better off moving your workstation closer to an outlet or spending $100 or so to have an electrician install a new outleteither of which is preferable to replacing damaged electronics or starting a fire accidentally.

Three years is more than enough time for you to test your UPS to find out if its a dud and whether it meets your needs in a real-world power outage. It wont last more than a few minutes under a heavier load, though; we measured a run time of just six minutes with a 300 W load. A UPS is designed to safeguard sensitive equipment and afford you the time required to shut everything down properly. Generators are expensive, though, and if you just want to keep the WiFi on the benefit may not justify the cost. Plus, when youre not in an outage, you can use its two USB ports to keep a phone and one other small device charged. This means that, unlike with some models we tested, your precious devices should have ample protection against common household power fluctuations as well as against less-frequent blackouts that trigger the battery backup. The CyberPower AVRG900U is a good option if our top pick and the Tripp Lite AVR750U are both unavailable and you dont need our upgrade picks premium features.

If youd like to immunise your business against protracted outages, then a generator system and a UPS make excellent partners: together, theyll keep the lights on for extended periods. Below those buttons is a cluster of four small LEDs that light up to indicate (clockwise from top left) when the unit is powered on, when the battery backup has kicked in, when the unit is overloaded, and when the AVR feature has kicked in. These small, affordable power units act as a power source for your sensitive electronics in case of a power outage. But in saving some cash, youre giving a few things up: It has the lowest capacity and peak power output of any of our picks, as well as the shortest cord and the skimpiest warranty. Instead a UPS buys you time to save everything, put your Plan B in place and then gracefully shutdown your essential systems. *At the time of publishing, the price was $220. It had the best clamping voltage of any model we tested, letting through just 397.2 volts. If you just want to keep your Wi-Fi powered during a blackout, this Amazon Basics option is a cheaper way to do so for around an hour and a half (thats how long it lasted with our 20 W fan). Its easy to use, and it has a compact design that fits comfortably under most workstations. But if you want to keep your home Wi-Fi network and some other key electronics up and running in the event of an outage, an uninterruptible power supply (UPS) might be a worthwhile investment. An uninterruptible power supply, or UPS, is basically a surge protector, a battery, and a power inverter (which turns the batterys stored energy into usable power) wrapped into one unit.
