The MARSRIVA KP1 Plus 18W Mini Router UPS is a compact DC backup power solution for compatible Wi-Fi routers, internet modems, ONU and fiber devices, network switches, CCTV accessories, and other low-power DC equipment. Its 59.2Wh lithium-ion battery uses a 16000mAh configuration with four 3.7V / 4000mAh battery cells, providing backup power during electricity cuts and power switching. Four DC outputs provide 12V, 9V, and 5V options for supported devices, while USB-C and USB-A outputs provide additional 5V power for compatible USB devices. The 0ms AC-to-DC transfer helps compatible connected devices continue running without interruption during power changes. With an 18W maximum total output, the KP1 Plus is intended for routers, modems, small network devices, and other compatible low-power equipment within its output limits. Designed for home internet continuity, office internet continuity, wall-mounted router areas, and small network cabinet setups, the Marsriva KP1 Plus supports practical installation near network equipment. Built-in wall-mount slots make installation easier in router areas, network cabinets, or home setups. Its air-cooling design helps maintain stable operation during long UPS usage, while the V-0 flame-retardant ABS + PC casing supports daily-use safety and durability. The unit accepts 100VAC–280VAC AC input and 12VDC–18VDC PV input. Compatibility depends on the connected device using supported DC connector sizes and polarity, as well as the applicable output voltage and current. Runtime depends on connected device power consumption, output voltage, number of connected devices, and battery condition.
