Marsriva KP4 10000mAh Smart Mini DC UPS for Router

MARSRIVA KP4 10000mAh Smart Mini DC UPS for Router exists to fix one specific frustration: the internet dying the moment the power does. An online class, a video call, a CCTV feed or a shop's order system all stop together during load-shedding — not because the devices lost power, but because the router did. This Mini DC UPS for Router keeps the router itself running, so the Wi-Fi never drops.

It is not a power bank. Inside the Marsriva KP4 is a 36Wh lithium-ion pack built from four 3.6V/2500mAh cells (10000mAh in total), and outside are the DC outputs a router actually uses — 12V/1.5A, 9V/2.0A and 5V/2.1A — plus USB-A and USB-C, each 5V/2.1A. That is five output ports with a maximum output of 18W, fed by a DC 12V/2.0A input.

The detail that matters most in a 10000mAh DC UPS is the changeover. The KP4 does an AC to DC transfer in 0 ms, so the router never reboots and a call or download in progress simply continues. Used as a DC UPS for WiFi Router duty, that difference is what separates staying connected from waiting two minutes for the router to come back.

Build quality suits a device that stays powered around the clock: an ABS + PC housing rated V-0 flame resistant, air-cooling heat dissipation and wall-mount slots on the back. At 120 × 120 × 28 mm and 355 g, this Router Backup UPS tucks in beside the router or hangs on the wall next to it. It works in 0°C–40°C in UPS mode and −15°C–50°C on battery.

Important Usage Instructions

• Check the voltage printed on your router's own adapter and use the matching 12V, 9V or 5V output.
• Power the unit from a DC 12V/2.0A input and keep it plugged in so the battery stays topped up.
• Keep total connected load within the 18W maximum output rating.
• Mount or place it in an open spot — the housing is air-cooled and should not be covered by cloth or boxed in.
• Keep it dry, away from direct sun, and within the stated operating temperature range.
