Reliable Power, Uninterrupted Connectivity
The MARSRIVA DC MINI UPS ET3 is specifically designed to solve the frustration of losing your internet connection during a power cut. By providing seamless DC backup power to your networking gear, it ensures you stay connected to the world, whether you are working from home, streaming media, or monitoring your property via CCTV .

High-Capacity 8400mAh Battery
Equipped with dual 4200mAh cells, the ET3 delivers extended runtime for your essential devices. Unlike standard power strips, this Mini UPS automatically kicks in the moment your main power fails, providing zero-delay switching so your video calls and downloads never stutter .

Versatile Multi-Device Support
Flexibility is key. The ET3 features three adjustable DC output ports (supporting 12V, 9V, and 5V) plus a standard USB port. This allows you to power a router, an ONU (Fiber modem), and a security camera simultaneously from a single compact unit .

Smart Safety & Compact Design
Safety is paramount. The MARSRIVA ET3 includes an intelligent protection system that guards against overcharging, overvoltage, and short circuits, keeping your expensive electronics safe. Its sleek, compact black chassis fits neatly on any desk or network cabinet without taking up too much space .
