Quick picks by situation

Router plus modem

APC Back-UPS is the starting point for common home network backup.

Power brick crowding

Check outlet spacing before assuming every device fits.

Long outage

Runtime depends on watt load and battery age, not just VA number.

ISP outage too

Skip overspending if the upstream service fails whenever power drops.

How to choose without overbuying

When to spend more

Spend more when the modem, ONT, router, and mesh node need to stay online through frequent short outages.

When to spend less

Spend less when you only need graceful shutdown time or your internet service fails during power cuts anyway.

FAQ

Will a UPS keep internet working?

Only if the modem or ONT, router, and upstream service remain powered and active.

What should plug into the UPS?

Start with modem or ONT, router, one key switch, and possibly one mesh node.

Do I need a huge UPS?

Not always. Network gear usually draws less power than desktops, but runtime depends on the actual load.
