Explanation
A battery backup, commonly known as a UPS (Uninterruptible Power Supply), is designed to provide continuous power to connected devices during a power outage. It contains an internal battery that automatically kicks in when the main power fails, giving users time to save work and shut down safely. A surge suppressor only protects against voltage spikes but provides no power during an outage. A portable generator is not directly connected to a computer and requires manual setup. A power inverter converts DC to AC power but requires an external DC power source such as a car battery, making it impractical as a direct computer connection for blackout protection.
