UPS for Wi-Fi Router: Keep Working From Home Through a Power Cut

When the power cuts, the first thing most people lose is not the lights: it is the internet. The fibre box and the Wi-Fi router go off with the mains, the video call drops, and the laptop battery suddenly matters.

The Prime Minister told Parliament on 3 November that Malaysia is among the countries considered potential targets of cyberattacks. In his words, "Do not assume these threats are far removed from us." For anyone who works from home, it is a good week to fix the weakest link in the home office.

Why your router needs a UPS

A router and a fibre terminal together draw only around 15 to 25W, but they need power without a gap. A UPS (uninterruptible power supply) sits between the wall and your devices and switches to battery the moment the mains fails, fast enough that most routers and computers carry on without restarting.

RIVER 3 UPS is built for exactly this job: it switches to battery in 20 ms, stores 245Wh and delivers 300W. DELTA 3 Plus switches in 10 ms and powers a whole desk. RIVER 3 Plus sits between them, with 286Wh, 600W and an optional extra battery.

How long will it last?

Typical wattages, with about 85% of rated capacity reaching your devices. A laptop that is already charged draws much less.

If the internet itself goes down

A UPS keeps your equipment running. It cannot keep your internet provider's network up. If an outage or an attack affects the provider, your router will stay on with nothing to connect to. Three cheap habits cover that:

• Keep a mobile data plan with enough quota to hotspot from your phone for a working day.
• Keep the phone charged from the power station's USB ports.
• If your work depends on one online service, download the files you need for the next day.

Setting it up properly

1. Put the power station near the router, on a hard surface with space around it for air.
2. Plug the power station into the wall, and plug the router and fibre box into the power station. A short extension strip helps if you need more sockets. Leave it like that permanently.
3. Test it: switch off the wall socket and check the Wi-Fi stays up.
4. Label the plug, so nobody unplugs it to use the vacuum cleaner.

Adding solar for longer cuts

RIVER 3 UPS takes up to 110W of solar input. The RIVER 3 UPS Solar Generator (PV60W) pairs it with a 60W portable panel, which refills the station in about six hours of strong sun, roughly a clear day. For a full desk through a longer outage, DELTA 3 Plus takes up to 1,000W of solar.
