Mini UPS Melchioni MK-7800: internet always on during blackouts
When the power goes out, the first devices to turn off are often Wi-Fi routers and ONT/ONU: even if the smartphone has a battery, the home connection drops and smart working, VoIP calls, home automation, and cameras are interrupted. The Melchioni MK-7800 was created precisely for this: a compact uninterruptible power supply that provides continuous DC power to network devices, keeping the line active during voltage drops or blackouts.
Thanks to its small size, you can install it near the router, behind a piece of furniture, or in a small technical area without taking up space like a traditional UPS.
Dual output 12V and 9V: compatible with many routers and ONU
The strength of the MK-7800 is the availability of multiple DC outputs, designed for the most common devices: DC 12V 2A (up to 24 W) for routers and ONU that require more current, DC 9V 1A (up to 9 W) for devices with 9V power supply. This way, you can power the most popular devices and have a stable backup without complicated adapters. The coaxial connectors ensure an immediate and secure connection.
18650 batteries: over 500 cycles and backup up to 6 hours
Inside you will find a high-quality 18650 lithium-ion battery, configured with 3 cells of 2600 mAh (total 7,800 mAh, equivalent to 28.86 Wh). It is a proven solution, designed to last, with a declared lifespan of over 500 charge cycles. The autonomy can reach up to 6 hours: an ideal value to cover most domestic interruptions and to keep connections operational in small offices or professional workstations (naturally, the actual duration depends on the real consumption of the router/ONU).
Integrated electronic protections: safety and reliability
For continuous use at home or in the office, the mini UPS integrates protections against: overload, overcharge, short circuit, excessive discharge. These protections help preserve the battery over time and protect connected devices.
Compact design: lightweight, tidy, ready for installation
Weighing only 210 grams and with compact dimensions of 110×73×25 mm, the MK-7800 is easy to position and manage even in tight spaces. The maximum output power is 27 Watts, suitable for most home network devices.
