APC Back-UPS BK350EI – Key Features

350 VA / 210 W Power Capacity: The UPS delivers up to 350 VA (210 watts) of backup power, making it suitable for supporting essential devices like desktop computers, routers, modems, and small office equipment during short power outages.
Battery Backup and Surge Protection Outlets: It includes multiple IEC outlets that provide both battery backup and surge protection for critical devices, while additional surge-only outlets protect less essential equipment from voltage spikes without draining the battery.
Sealed Maintenance-Free Battery: The unit uses a sealed lead-acid battery that requires no regular maintenance, ensuring reliable performance and allowing easy replacement when the battery reaches the end of its lifespan.
Backup Runtime for Safe Shutdown: During a power outage, the UPS can typically supply power for several minutes depending on the load, giving users enough time to save work and properly shut down connected devices.
Surge and Spike Protection: Built-in surge suppression protects connected electronics from damage caused by lightning strikes, power surges, and unexpected voltage spikes.
LED Indicators and Audible Alarms: The UPS provides clear visual indicators and audible alerts to inform users about power status, battery operation, overload conditions, and when the battery needs replacement.
Standby (Offline) UPS Topology: The BK350EI operates in standby mode, meaning it switches to battery power automatically and quickly when it detects a power failure, ensuring minimal interruption to connected devices.
Compact Tower Design: Its compact vertical design allows it to fit easily under desks or beside workstations, making it ideal for home or small office environments.
