Keep Wi‑Fi / modem up in a blackout

Outages kill the internet at the wall wart — not always at the street. Size a station for modem / ONT + router (and mesh nodes), know UPS vs portable station, and the mesh caveats that surprise people.

What actually needs power

  • Modem / ONT / gateway. Cable modem, fibre ONT, or ISP combo box — often ~8–20 W. If this brick dies, nothing else matters.
  • Wi‑Fi router. ~5–15 W typical for a single unit.
  • Mesh satellites. Each node is another 5–15 W — three-pack mesh can rival a laptop. Power every node you care about, or accept dead rooms.
  • ISP street power. Battery at home does not revive a dark neighbourhood node. Your station only helps when the last-mile is still lit.

Typical single-gateway + router: ~15–30 W continuous. Specs below from manufacturer pages (checked Oct 2026). For laptop + monitor stacks see WFH outage.

UPS vs portable power station

  • Classic UPS. Great for flicker / minutes of bridge so Zoom doesn’t drop on a blip. Wh is tiny — often not an all-evening Wi‑Fi plan.
  • Portable station with UPS / EPS mode. Sub‑20 ms switchover plus hundreds of Wh — the usual QuietWatt answer for multi-hour blackouts.
  • Don’t daisy-chain UPS → station unless both makers say it’s OK.
  • USB-C routers. Some modern gear takes USB-C PD — you can skip AC inverter losses if the station has a high enough PD port.

Mesh caveats

  • Power the primary + every satellite you need, or coverage shrinks to one room.
  • PoE injectors / switches add watts — include them in the budget.
  • Guest / IoT SSIDs don’t need extra Wh; extra APs do.
  • Phone hotspot is the fallback when the ISP path is dark — charge the phone on the same station.

Wh math (estimates)

Hours ≈ (rated Wh × 0.85) ÷ average watts.

Modem + router (~20 W)

~12–87 h

286 Wh ≈ 12 h · 1,024 Wh ≈ 43 h · 2,048 Wh ≈ 87 h (estimates)

Gateway + 2 mesh nodes (~40 W)

~6–43 h

286 Wh ≈ 6 h · 1,024 Wh ≈ 21 h (estimates)

+ Phone charge (~10 W extra)

Still overnight+

Even compact stations usually cover Wi‑Fi-only nights; mesh is what forces a size-up.

Comparison: Wi‑Fi blackout stations

Filter by outage length. Prefer UPS-class switchover if flickers drop your VoIP.

Model Wh · UPS Est. modem+router Mesh / notes Approx. USD
EcoFlow RIVER 3 Plus Compact 286 Wh · UPS <10 ms ~12 h @ 20 W (est.) Fine for single router; expand before big mesh. ~$180–300
Anker SOLIX C300 288 Wh ~12 h @ 20 W (est.) Closet-shelf Wi‑Fi kit; watch continuous W on chunky gateways. ~$200–280
Jackery Explorer 1000 v2 Quiet 1,070 Wh · UPS <20 ms ~40+ h @ 20 W (est.) Comfortable mesh budget; quiet for hallway placement. ~$499–589
BLUETTI Elite 100 V2 1,024 Wh · UPS ≤10 ms ~40 h @ 20 W (est.) Fast switchover for finicky ONTs. ~$380–500
Anker SOLIX C1000 Expand 1,056 Wh · UPS <20 ms ~40 h @ 20 W · double with pack Add battery when mesh + phones share the box for days. ~$400–600
EcoFlow DELTA 3 Plus 1,024 Wh expandable · UPS <10 ms Wi‑Fi is trivial; leftover Wh for lights / fridge Storm kit hub — see storm kit. ~$600–900+
BLUETTI AC200L 2,048 Wh Days of modem+router (est.) Overkill for Wi‑Fi alone; great shared house battery. ~$800–1,100

QuietWatt is independent. Runtime figures are estimates — ISP uptime is not guaranteed by any battery.
