What is a UPS?

UPS is an acronym that means "Universal Power Supply".  This is a back-up power supply for computing equipment that allows computers to keep running through a brief power outage.

During thunderstorms, it is not unusual for the electric power supply to homes and businesses to go out for a few minutes due to lightning strikes on utility equipment or tree branches falling and damaging power lines.

A UPS has a battery and an a DC to AC converter to supply 120 volt A/C power to run equipment.  The capacity of most UPS can run a computer for an hour or so when no power is available.  The main purpose is to allow users to save their work in an orderly fashion and power down their computer without losing their work.  Most UPS also include surge protection to protect items plugged into it from power surges.

Do you need a UPS?

If you have a desktop PC, you may benefit from a UPS.  A UPS will protect you from losing your unsaved work when power outages occur, and can allow you to continue working for some time without electric power.  You can also power peripherals such as printers using a UPS.  You will also benefit from surge protection which protects your computer equipment from power surges.

If you have a tablet computer or laptop, you do not need a UPS since these devices have a built-in battery and are not immediately affected by power interruption.  You may want to consider a surge protector to protect your equipment from power surges.
