An APC 1200VA UPS (Uninterruptible Power Supply) is a battery backup device that protects sensitive electronics like computers, Wi-Fi routers, and gaming consoles from power outages, surges, and voltage fluctuations.
Capacity: 1200VA (Volt-Amperes) translates to 650 Watts of actual power output.
Technology: Line-Interactive, meaning it instantly switches to battery power during a blackout and stabilizes low/high voltages using a feature called Automatic Voltage Regulation (AVR).
Outlets: Usually features 4 to 6 sockets (Universal or IEC) that provide both battery backup and surge protection.
