You know stress when your power cuts off during a storm two hours before you need to submit a research paper. Fortunately, there are ways to prevent and deal with both stress and power outages!

A solution to this problem, and many others like it is an Uninterruptible Power Supply, or UPS for short. A UPS is a device that is utilized as a power “back-up” for your desktop computer in the event of a power outage. Aside from being a backup power source, a UPS can also prevent a power surge, or spike in your electrical current, which can ultimately cause damage to your home, appliances, and electronics. With an Uninterruptible Power Supply, you can protect your computer from damage and continue to work on your projects throughout any storm or power interruption. Of course, now you may be wondering what type of Uninterruptible Power Supply you should get. UPS units vary in size, from small to large, and can be used to power a single device or multiple devices.
