The best UPS (Uninterruptible Power Supply) devices on this page are major purchases for any business, or home user, who needs electronics like PCs and servers with constant 24/7 power connections.

Even if there is a brief power outage, the results can be catastrophic, as servers can become inaccessible and data can even become corrupted if a computer suddenly shuts down.

That's where the best UPSs come in, because if there's a power outage, they'll seamlessly switch to battery power and your devices will stay up and running until main power is restored or you can safely shut down your device.

You may find that you are connecting too many power-hungry devices to your home power source, and this can lead to power outages or spikes. Your home may not have the backup power solutions your office does, so buying a UPS for your home can be a very smart investment.

The UPS devices included in this guide cover a wide range of use cases, from small home UPS devices that can keep a router and PC running, to large, powerful UPS devices for corporate use. Therefore, we have listed these best UPS devices in no particular order.

What is a UPS?

UPS stands for Uninterruptible Power Supply, it is a device that works as a backup battery in case of power failure. Small UPS machines for homes and offices provide enough power for a few minutes, so there is time to shut down devices properly without losing work. The largest UPS systems can last even a few hours, but you generally won't find them in homes or small offices.

How to choose the best UPS for you?

When choosing a UPS for you, start by considering where you will be using it: at home or at the office? If it's a small home or office that needs power, a small UPS will do just fine.

You will want to evaluate the size and shape of the UPS system. While some are compact and fit on desktops, others are larger and can be tower or rack mounted. There are some UPS machines that can be used both as towers and in racks.

Next, you need to assess how much power your devices require and how long power is needed when there is a power outage. If it takes a few minutes for your device to shut down, be sure to select a UPS system that can provide sufficient runtime for this.

The best UPS: how we tested it

We test these UPS machines at various points, starting with the environment they are best suited for: home, small office, or server farm?

We look at how much power these devices provide, how much runtime they offer during power outages, and their form factor (desktop, tower, or rackmount). We look at its specifications, such as input voltage, output capacity, battery life, and charging time. We also considered how many plugs they had and whether there was enough space between them for wide plugs.
