No, although a UPS frequently has surge protection built in. UPS stands for uninterruptible power supply, meaning in the event of a power outage, it maintains electricity to your device. These are frequently used with computers and associated equipment, so you can keep working if there's a blackout. In essence, it's a kind of battery backup. And like all batteries, a UPS eventually runs flat. It depends on the power available and the number of things plugged into it. A small UPS might run for 15 to 30 minutes. Even large ones seldom run for more than a couple of hours.
