This helps prevent disconnections during streaming, video calls, online gaming, or other ongoing activities that rely on a stable connection.

How Do You Set Up an Uninterruptible Power Supply for a Router?
It’s pretty easy to set up an UPS power supply for a router. Here we will show you how to use the uninterruptible power supply in simple plug-and-play steps.
Step 1. Choose the Right UPS
Your setup depends on your NBN connection type:
Basic use (router only): A 400–800VA UPS is usually sufficient
Router + modem/NBN device: 800–1200VA recommended
Plug type: Ensure compatibility with Australian Type I sockets
Step 2. Connect Your Devices Properly
Plug the UPS into a wall outlet and fully charge it (6–8 hours recommended)
Connect your router to the battery backup outlets on the UPS
If using NBN:
FTTP: Connect the NBN NTD
HFC/FTTC: Connect both the modem and router
Turn on the UPS and confirm everything is working
Step 3. Maximise Runtime
To extend backup time:
Only connect essential devices (router + modem)
Enable energy-saving features if available
Turn off unnecessary devices
Replace the UPS battery every 2–4 years
Step 4. Test and Maintain
After setup:
Simulate a power outage by unplugging the UPS
Check if your Wi-Fi remains stable
Measure how long the system runs
Maintenance tips:
Test every 3–6 months
Keep the UPS in a cool, dry place (important in Australian summers)
Monitor battery condition

FAQs
How long can a UPS power my router?
How long a UPS can run your router mainly depends on two things: how much power your router uses and how large the battery is. Most WiFi routers use around 10–20W, so they don’t need much power to stay on.
A basic mini UPS usually keeps a router running for about 1–3 hours, which works well for short outages. If you need longer backup, a larger option can keep your router running for many more hours, depending on usage.
What size UPS do I need for a router?
For a single router and modem, a 200-300Wh uninterruptible power supply for the router is usually enough to provide several hours of backup.
If you want a longer runtime or plan to power additional devices such as a modem, mesh node, or small network switch, a 500-1000Wh power station is usually a better option.
Is a router UPS worth it?
Yes, a dedicated, uninterrupted power supply for a WiFi router can be very worthwhile. Even a short outage can disconnect your internet, which then interrupts your work, streaming, or smart home systems.
A UPS keeps your router and modem running automatically, preventing sudden shutdowns and maintaining a stable network connection during outages.
Modern solutions such as portable power stations are considered a solid choice. They can power routers and other small electronics at the same time, which means they are a practical backup option that is more versatile than basic UPS units.
