What size power station for a Wi-Fi router and modem?

It needs a station with at least 28 W of continuous output. At the default 85% efficiency it takes about 264 Wh of rated capacity for 8 hours of running, and 791 Wh for 24 hours of running. 54 of the 54 power stations in the Enough Watts data set can power it. The smallest one that keeps it going for 24 hours of running is the BLUETTI Elite 100 mini (1,005 Wh).

The math

Worked with the typical figure, as the calculator does it.

Output28 W running, so the station's continuous output must be at least 28 W.
SurgeNo start surge: the running figure covers it.
Average draw28 W: the running watts count for every hour it is on.
A typical day28 W × 24 h = 672 Wh a day.
8 hours of running28 W × 8 h = 224 Wh usable, ÷ 0.85 = 264 Wh of rated capacity.
24 hours of running28 W × 24 h = 672 Wh usable, ÷ 0.85 = 791 Wh of rated capacity.
On the BLUETTI Elite 100 mini1,005 Wh × 0.85 = 854 Wh usable, ÷ 28 W = 30.5 h.

What moves the number

The figure adds maker maximums for a router and a cable modem, so real draw sits lower: 28 W typical, 10 W for a router alone on fiber, 44 W for a high end router with a modem. Most routers and modems run from 12 V adapters plugged into an outlet.

Questions

How many watts does a Wi-Fi router and modem use?

About 28 W while running, from 10 W to 44 W across the models in our sources. That figure is an estimate: few published figures exist for this type. Watts vary by model and age. Check the label on your own appliance and enter it for an exact answer.

Can a portable power station run a Wi-Fi router and modem?

Yes. All 54 power stations in the Enough Watts data set can power it on its own. It takes at least 28 W of continuous output.

How long will a power station run a Wi-Fi router and modem?

It depends on the battery. At 85% efficiency the smallest station that powers it, the BLUETTI Elite 10 Mini (128 Wh), gives about 3.9 h. The largest, the EcoFlow DELTA Pro Ultra X (12,288 Wh), gives about 15.5 days.

Does a Wi-Fi router and modem need extra watts to start?

No. It has no motor or compressor, so it draws about its running watts from the moment it is switched on. The check that matters is a continuous output of at least 28 W.
