Plus, it has only eight outlets four with battery backup , fewer than any of our picks. The CyberPower CPPFCLCD has a shorter run time 90 minutes at a 20 W load, six minutes at a W load and peak power output W compared with either of the similarly priced models we tested, as well as some models that cost less than half as much. Sarah Witman has researched, tested, and reviewed all manner of products—from massage chairs and mousetraps to pencils and power banks—since joining Wirecutter in Before that, she worked as a science writer and fact checker for numerous publications, and she studied journalism at the University of Wisconsin.
In her spare time, she eats as much cheese as her body will tolerate. Our pick. CyberPower CPAVR The best UPS for a home network With five outlets on battery backup and 10 outlets total, this UPS can reliably keep your Wi-Fi network running for up to four hours in a blackout or keep your home-office setup powered long enough for you to save your work and shut down.
Buying Options Buy from Amazon. Upgrade pick. Budget pick. Everything we recommend. Why you should trust me. Who this is for. How we picked. Automatic voltage regulation AVR : We required our upgrade-pick contenders to have AVR, and we strongly preferred it in all other models.
AVR, also called line-interactive topology, is a more advanced form of power management than the type that less-expensive models use. This reduces wear and tear, especially if you live somewhere with frequent brownouts, and prolongs the overall life of the battery.
It also provides more-reliable power to sensitive gear such as hard drives. Pure sine-wave inverter: We required this feature in our upgrade-pick contenders and preferred it in all other models. A pure sine-wave inverter can produce electrical waveforms as clear and smooth as those of the AC power coming out of any wall outlet, whereas modified sine-wave inverters produce choppier waveforms.
You should also avoid using a UPS with a modified sine-wave inverter for sensitive audio equipment which can pick up buzzes of interference from the unit and medical devices that require pure AC power. The pure sine wave from a residential wall outlet.
Rated for at least VA output: Most models explicitly include their output in the name or model number in volt-amperes VA. For our upgrade pick, we looked for models with at least a 1, VA rating. At least four battery-backed outlets: All outlets on a UPS provide surge protection, limiting the amount of extra voltage that can reach and potentially damage your devices—which is good because you should never plug your UPS into a surge protector or plug a surge protector into a UPS.
But generally only half the outlets are connected to the backup battery and are prominently marked as such so that they stay on when the power goes out. A set of four battery-backed outlets is enough for you to plug in a modem, router, desktop computer, and external hard drive—just make sure to plug the right devices into the right outlets.
A 5-foot cord should be long enough for most people, but when an even longer cord is available, we prefer that. User-replaceable battery: Most UPS batteries are small, sealed, lead-acid batteries—more like a car battery than the one in your smartphone or laptop. Plus, as demonstrated in this video , the process is simple enough for a novice to complete in just a few minutes. Even better, software that works on any operating system is future-proof even if you replace some of your equipment, so your UPS can be just as useful years down the line as it is the first day you plug it in.
After applying these criteria to the available options, we were left with 12 contenders to test:. How we tested. We tested the performance of each model in a few key areas, including the following:. For this test, we plugged in the UPS and turned it on. Then we unplugged it—leaving it running on its battery—and plugged in household appliances with known power draws such as an array of 50 W halogen bulbs, a couple of 10 W lamps, and a W fan that we had tested using a Kill A Watt power meter one by one until the battery overloaded and the UPS shut down.
Then we added up the total maximum power draw based on the appliances we had plugged in and recorded the maximum output in watts. Battery capacity watt-hours, or Wh and run time: Manufacturers often publish run-time ratings that outline how long a UPS can keep devices of various wattages running. Since most ratings are based on ideal conditions, we tested our top candidates at two different loads to see how they would perform in real-world use: 20 W, representing the combined power draw of a household modem and router, and W, representing the power usage of a PC, modem, router, and external hard drive running simultaneously.
Then we plugged in an array of six halogen bulbs totalling W and unplugged the UPS, leaving it running on its battery. We then repeated the test with two 10 W lamps, measuring the run time with a 20 W load. Surge protection: Applying the same equipment and protocol we use to test surge protectors , we zapped each UPS with 5,volt power surges and measured how many volts they let through.
A lower let-through voltage also called clamping voltage is better, since you want as few volts as possible to get through to your devices. We recorded the maximum amps and volts, and we multiplied them to calculate the total output in watts. Look and feel: We considered the usability of the interface, the layout and spacing of the outlets and ports, the shape and size of the unit, and the overall design.

FDX are two leading delivery services companies and main competitors to each other, at least in the public eye.
However, to those following them closely, the two companies are quite different in their business models and strategies. Here we review and contrast how the two companies approach a variety of business challenges, such as online commerce, logistics, express services, and ground delivery. While UPS is widely known for its domestic ground package delivery, FedEx is mostly recognized for its global air express freight. The two companies also differ in terms of their approaches to serving customers, how they have fared in the e-commerce environment, and the different business structures unique to each company.
Package delivery and express service are where the two companies have made names for themselves. Each company has other delivery services that make everything they do seemingly overlap. In reality, UPS's ground package business and FedEx's air express operations are, respectively, the bread and butter for each company.
UPS delivers packages worldwide on every day except Sunday. In , UPS delivered around The UPS Store and FedEx Office are retail outlets set up by the two companies to bring in individual shipping orders for their respective package delivery and express services. Having such stores and offices also represents the different approaches by UPS and FedEx to serve their customers.
While both outlets provide shipping, packaging, and certain office supply services such as copying and printing, they attract different kinds of customers because of the different nature of each company's underlying delivery business.
The UPS Store is often a relatively small retail setting, independently owned by franchisees. It primarily serves retail customers and small businesses for their small package delivery needs plus certain postal and shipping-related services. The ongoing e-commerce development has played right into UPS's core business of small package delivery. As more people make purchases regularly online, merchants on the Internet are increasingly pressured to make their offline delivery of goods on time to customers.
They see logistics as having a much bigger role in retail success, and to help themselves better navigate through the e-commerce way, online merchants rely on package delivery companies such as UPS to make the final connections to their customers. As a result, UPS has seen increased demand for its business and has even struggled to keep up its capacity during times of heavy shipping orders. UPS manages all its businesses, such as air, ground, domestic, international, commercial, and residential through a single pickup and delivery network.
The single network structure has allowed UPS to gain competitive strengths by maximizing network efficiency and asset utilization. FedEx Corp. FDX moves more than 18 million shipments each business day as of FY20 to more than countries and territories around the world.
