MARSRIVA ET3 8400mAh Smart Mini DC UPS for Router with 18W Fast Output

MARSRIVA ET3 8400mAh Smart Mini DC UPS for Router

The MARSRIVA ET3 is a compact mini DC UPS for router setups, built to keep your home or office network online during sudden power cuts. With a built-in 8400mAh lithium-ion battery, the ET3 automatically switches to backup power the instant the main supply drops, so your router, ONU, or modem stays connected without a noticeable break.

Unlike bulky traditional UPS units, this router backup power device is designed to sit neatly behind your networking equipment or mount directly on a wall. It's a practical pick for anyone who relies on stable internet for work-from-home calls, online classes, gaming, or smart home devices that simply can't afford a dropped connection.

With three DC output ports and one USB port, the ET3 can support multiple compatible devices at once, making it a flexible mini UPS solution for small networking setups rather than a single-device backup.

Key Features

• 3 DC Ports + 1 USB Port: Powers multiple compatible networking devices simultaneously, so you're not limited to backing up just one router.

• 8400mAh Built-In Battery: A 3.6V / 8400mAh lithium-ion cell (4200mAh x 2) stores enough charge to keep your network running through short to moderate outages.

• 18W Maximum Output: Delivers enough power for common routers, ONTs, and small networking gear without overloading the unit.

• 0ms Switching Technology: Instant AC-to-DC transfer means your connected devices keep running through power fluctuations instead of restarting.

• V-0 Flame-Retardant ABS + PC Casing: Built with safety-rated materials for more reliable, long-term everyday use.

• Wall-Mount Ready: Built-in mounting slots let you install it neatly near your router without extra cables trailing across a desk.

• Air-Cooling Design: Helps the unit dissipate heat efficiently, supporting stable performance during extended backup periods.
