When the grid drops, so does the wall wart that powers your modem and Wi-Fi router—unless they are already on a battery. A small portable power station with UPS-speed switchover can keep internet, work-from-home video calls and smart-home hubs online through a short outage without a generator. This short guide covers how much power networking gear really uses, how to hook it up, and two budget BLUETTI pieces plus a step-up.

Safety first: plug the modem and router into the power station’s outlets (or a quality strip on the station). Do not backfeed a wall receptacle from the station. For whole-home or panel-tied backup, see the longer home backup power station sizing guide and hire a licensed electrician.

How much power does Wi-Fi need?

Most cable or fiber gateways plus a Wi-Fi router draw roughly 10–30 W combined. At 20 W continuous, a 288 Wh battery is on the order of 10+ hours of runtime before inverter losses—often a full workday or overnight. Add a laptop charger (45–100 W while charging) and runtime drops fast, so keep “internet only” on a small station and put the fridge on a larger one if you have both.

UPS-class switchover (under about 10 ms) matters here: many routers reboot if power blinks. Leave the modem and router plugged into the station full-time so they ride through flickers, and keep the station plugged into the wall so it stays charged.

Setup tips

Curated BLUETTI picks for internet backup

Prices from bluettipower.com as of November 5, 2026—as of Nov 2026, check current price before you buy.

  1. BLUETTI Elite 30 mini — about $249.99, 288 Wh / 300 W, <10 ms UPS. The dedicated router/laptop backup pick: enough Wh for networking gear for many hours, small enough to sit near the desk or entertainment center, and UPS-fast so Wi-Fi doesn’t reboot on a blink.
  2. BLUETTI SORA 60W solar panel — about $129. Optional daytime top-up for the Elite 30 mini (or another compatible station) during multi-day outages. 60 W won’t refill a big station quickly, but it’s a sensible match for a mini pack if you have sun and a place to unfold the panel.

Step-up: if you also want to run a fridge, CPAP or lights on the same box—or want more Wh headroom—look at the BLUETTI Elite 100 V2 (about $499, 1,024 Wh / 1,800 W, 10 ms UPS) or the other essentials/whole-home options in the sizing guide. Shop the BLUETTI store for current kits. All picks are on Products → Home Backup Power.

Bottom line

For internet-only backup, a small UPS-class station like the Elite 30 mini is usually enough. Keep modem and router plugged into it year-round, add a SORA 60 panel if you want solar top-ups, and step up to the Elite 100 V2 (or a larger unit from the sizing guide) when you need fridge-level watts or longer shared runtime.
