What is the name of the device that serves as a temporary power source in the event of a blackout?

The Uninterruptible Power Supply (UPS) serves as a temporary power source during a blackout, allowing devices to keep running for a short period of time. This functionality is crucial for maintaining the operation of essential equipment, such as servers or computers, preventing data loss and ensuring that tasks can be completed or saved before an orderly shutdown occurs. A UPS typically contains batteries that provide power when the main electrical supply is disrupted.

In contrast, while a battery backup also provides power, it is generally a more basic setup without the integrated features of a UPS, such as surge protection and system monitoring. A surge protector is designed to protect devices from voltage spikes but does not supply power during outages. A power distribution unit manages and distributes power to multiple outlets, but like the surge protector, it does not have the capability to provide backup power during a blackout.
