Imagine that you have just finished writing your company's mission statement when the power suddenly surges and goes out. If you're on a desktop, you face a significant risk that everything you worked on is gone.

Don't let that happen by getting an uninterruptible power supply (UPS), better known as a battery backup. Saving your work is one important reason to have a UPS. Another is to reduce unnecessary stress from power surges, a leading cause of hardware failures that render your devices unusable and often beyond repair.
