How to Keep Working Through a Power Outage at Home

A storm knocks the power out for two hours on a Tuesday afternoon. Your desktop dies instantly. Your monitor goes black. The Wi-Fi router blinks off, and the cable modem with it. If you work from home, that's not an inconvenience — it's a missed deadline, a dropped call, a "sorry, I lost connection" you have to send from your phone's hangnail of signal.

The good news: outages are short, predictable, and survivable on a battery you already half-own. You don't need a generator or a whole-home backup. You need a small, deliberate plan for three things that fail together — power, internet, and a place to work — and roughly 90 watt-hours of battery to ride out the average interruption.

Key Takeaways

What Actually Fails (and in What Order)

When the lights go out, things drop in a specific sequence, and knowing it tells you exactly what to back up:

Notice the pattern: the laptop and phone are the survivors. Everything that plugs straight into the wall — desktop, monitor, router, desk lamp — is what cuts you off. So the cheapest, most reliable outage plan isn't a generator. It's a laptop, a charged power bank, and a tested hotspot.

How Long Outages Actually Last

It's easy to over-prepare here. According to the U.S. Energy Information Administration's Electric Power Annual 2024, the average U.S. customer saw about 11 hours of interruptions in 2024 — but that was a hurricane year, and major events accounted for 80% of those hours. Strip out the storms and the routine number is small: service interruptions not triggered by major events "routinely average about two hours per year."

What most people get wrong: they plan for a 12-hour blackout and buy a generator they'll use once a decade. The honest math says prepare for a 1–3 hour outage you'll hit a couple times a year. A single laptop-class battery clears that bar with room to spare — and you'll actually use it every week.

The Three-Layer Backup Plan

Layer 1: Power — one laptop-class battery

A 16-inch laptop's internal battery already buys you a few hours. The job of a power bank is to extend that — to top the laptop back up mid-outage, and to keep the phone alive (your hotspot will eat battery fast). For that you want a USB-C bank with real laptop wattage, not a slim phone charger.

Two genuinely good options, both with the high-wattage USB-C output a laptop needs (USB Power DeliveryUSB-C PDUSB Power Delivery: the spec that lets USB-C deliver up to 100W (240W on PD 3.1) of charging power. A 90W+ PD monitor can charge most laptops while also handling video and peripherals over a single cable. now reaches up to 240W, so a 140W-class bank tops even a big laptop at full speed):

  UGREEN Nexode 25,000mAh 145W power bankabout 90Wh, enough to refill a typical 16-inch laptop nearly a full time over, with 145W output so it charges at desk speed, not trickle speed. It's on our power-banks shortlist.
• →
  Anker 737 Power Bank (24,000mAh, 140W)same idea at 86.4Wh, with a small screen that shows remaining charge so you're never guessing how much runway is left.

Either one is overkill for a single 2-hour outage and exactly right as your everyday "battery anxiety is gone" device.

Layer 2: Connectivity — your phone is the modem

The mistake here is assuming your home internet is the backup. It isn't — the router and modem are wall-powered and die with everything else. Your phone hotspot is the connectivity layer. A modern phone on cellular can carry video calls, email, and most web work fine.

Two things to do today, not during the outage:

Layer 3: A place to work — the go-bag rig

If the outage runs long, the answer is to relocate — a café, a library, a co-working drop-in. That's the same kit as your "work from anywhere" rig, which is why building it once pays off twice. A power bank plus a compact dock turns a borrowed table into a real desk: one cable to the laptop, then a second screen, Ethernet, and your peripherals hang off the dock.

The Anker 13-in-1 USB-C Docking Station is a reasonable travel-and-backup dock — it adds dual HDMI, Ethernet, USB-A ports, and an SD reader through a single USB-C connection, so a coffee-shop monitor (or a hotel TV with HDMI) becomes a second display. If you need a heavier, desk-grade dock instead, our docking stations picks cover the Thunderbolt tier.

Build It Before You Need It: A 4-Item Checklist

That's the whole plan. It costs less than a generator, fits in a bag, and unlike a generator you'll use the same gear every week — on the train, in a café, on the patio when the weather's good.

One Travel Note

If your "work from anywhere" plans include flying, keep the power bank with you. Per the TSA's power banks rule, lithium-ion power banks are allowed in carry-on only — they're prohibited in checked luggage. Both banks above sit under the common 100Wh airline threshold, so they fly without special approval. Pack them in your bag, not your suitcase.
