Can a power station run a Wi-Fi router + cable modem?

Updated
Short answer

Yes. A router and cable modem together draw about 25 W, so a 288 Wh power station keeps them on for about 10 hours and a 1,000 Wh unit for about a day and a half.

Routers and modems use far less than their power adapters suggest. An adapter is sized for the worst case; NETGEAR Nighthawk routers, for example, ship with a 42 W one. We plan on 25 W for a router and modem together, which leaves some margin. The real range is about 10 to 66 W depending on your gear.

There is no start-up surge, so any station in our table can run them. The question is how long. Left on for 24 hours, 25 W adds up to about 600 Wh. After inverter losses, that is roughly 700 Wh of battery per day. A 288 Wh unit gives about 10 hours, a 500 Wh unit about 17, a 1,000 Wh unit about 34 to 36 hours, and a 2,000 Wh unit close to 3 days.

Two things can make a power station the wrong fix. First, your internet only works if your provider's network still has power. In a wide outage, local equipment may go down too, and no battery at home will bring the signal back. Ask your provider how their network handles outages. Second, if you mainly need to send messages and check news, a phone on cellular data may cover you with far less battery.

How long does each power station run a Wi-Fi router + cable modem?

At about 25 W on average, a Wi-Fi router + cable modem runs for about 9.5 hrs on the 286 Wh EcoFlow RIVER 3 Plus, about 34 hrs to 36 hrs on a 1,000 Wh-class unit (998–1,070 Wh) and about 6 days on the 4,096 Wh EcoFlow DELTA Pro 3.

Estimate: battery Wh × 0.85 ÷ 25 W average (25 W × 1 duty). Your model may draw more or less; check its label. Prices are typical ranges we checked by hand on October 9, 2026, not live prices.

Where these numbers come from

A TP-Link Archer AX55 router uses a 12 V, 2 A (24 W) adapter, but routers and modems usually draw well under their adapter ratings. 25 W for both boxes together is a safe planning number, about 600 Wh a day.

Make it last longer

  • • Turn on the station's UPS or pass-through mode and leave the router plugged into it all the time. Most units in our table list a switch-over of 10 to 20 milliseconds, which is meant to keep the connection up when the grid drops.
  • • Skip the inverter if you can. Many routers and modems run on 12V adapters. A 12V DC cable with the right plug, run from the station's car port, avoids the 10 to 15% inverter loss. Match the voltage and plug exactly.
  • • Unplug extra gear. Mesh nodes, network switches and smart-home hubs all add to the load.
  • • Turn the router off overnight if nobody needs it. Eight hours off saves about 200 Wh.

Common questions

How long will a power station run a Wi-Fi router?
About 10 hours on a 288 Wh unit, 17 hours on a 500 Wh unit, and 34 to 36 hours on a 1,000 Wh unit. That assumes 25 W for a router and modem together. A single small router alone may use less.
Can a power station work as a UPS for my router?
Many can. Most stations in our table list a switch-over time of 10 to 20 milliseconds, and Jackery pitches the Explorer 300 v2 for keeping a modem or router on through a flicker. Test it by unplugging the station from the wall while you are online.
Will my internet work during a power outage if I power my router?
Only if your provider's network still has power. Cable and fiber service rely on local equipment that can also lose power in a wide outage. Your router will be on, but there may be no signal coming in.
Can I run my router and a laptop at the same time?
Yes. A router, modem and laptop together average about 64 W, so a 1,000 Wh unit lasts about 13 to 14 hours. Charging the laptop from a USB-C port instead of its AC adapter stretches that a little.
