Mini UPS (Router Backup)

A Mini UPS (Router Backup) is a compact uninterruptible power supply designed to keep Wi-Fi routers, modems, and small networking devices running during power outages. It typically uses built-in lithium batteries to provide backup power for several hours, ensuring stable internet access for work, online classes, streaming, and smart home devices. Mini UPS units often support multiple voltage outputs, automatic power switching, overcharge protection, and silent operation, making them a practical solution for homes and small offices that rely heavily on continuous internet connectivity.
