A power outage can happen at any time and can be very disruptive, especially if you rely on electronics for work, entertainment, or communication. When the power goes out, devices that are plugged directly into the wall will immediately turn off. This sudden loss of power can cause data loss or even permanent damage to sensitive electronics. That's where an uninterruptible power supply, or UPS, comes in. A UPS acts as a backup power source, providing power from its built-in battery when the main power source fails. This allows connected devices to continue operating normally during an outage.
