SFN Multi-Output Mini UPS for Router and DVR

SFN Modem UPS is a compact backup power solution designed for modems, routers, ONT devices, DVR/NVR systems, security cameras, and other low-voltage electronic equipment. It helps keep internet connection and security systems running during power outages, making it suitable for homes, offices, shops, small businesses, and surveillance installations.

The device uses a real 12V 7Ah battery, providing approximately 84Wh energy capacity. Unlike many small powerbank-style products that are marketed with high mAh values based on 3.7V cells, this unit offers higher usable energy for 12V devices and longer backup time in real working conditions.

With 5V, 9V, and 12V output options, SFN Modem UPS can support different device types from a single unit. It includes 2 DC outputs for modem, router, DVR, camera, or similar devices, plus 1 USB 5V output for mobile phones, tablets, and small electronics. Each DC output supports up to 3A, depending on the connected device and total system load.

Typical backup time may reach 5–7 hours for a modem/router, around 4–5 hours when powering a modem and charging a phone once, or up to 2 hours for a DVR with 3–5 cameras, depending on the total power consumption of the connected devices.

The product is supplied with 2 male-to-male DC power cables. A 12V adapter is not included; users can normally use the existing 12V adapter from their modem, camera, or DVR system during installation.

SFN Modem UPS is easy to install, portable, and suitable for B2B buyers looking for a practical mini UPS solution for internet continuity, security systems, and low-voltage backup power applications.
