Emergency Preparedness: Power Outages, 72‑Hour Kits, and Critical Device Backup
Why Emergency Preparedness Starts With Power
Most emergency plans fail because they assume the grid will come back quickly. A realistic plan starts with 72 hours of independent power for communications, medical devices, refrigeration, and essential work.
This page links to every major emergency‑preparedness guide on BBB, including blackout planning, medical continuity, Wi‑Fi uptime, 72‑hour solar kits, and the best emergency battery backups for outages.
Keeping Communications Online During an Outage
Your modem, router, and phone are your lifeline during an emergency. These guides show how to keep them powered for hours or days.
- how to keep Wi‑Fi running during a blackout
- how to keep your phone powered during a disaster
- runtime calculator for routers and modems
Medical Device Preparedness
Medical devices must stay powered regardless of grid conditions. These guides cover oxygen concentrators, CPAP, and general medical equipment.

Home Office and Remote Work Preparedness
If you work from home, a short outage can cost hours of productivity. These guides show how to keep your office online with minimal power.
72‑Hour Backup Kits and Outage Planning
A 72‑hour kit is the foundation of emergency preparedness. These guides show how to build a compact, portable system that covers your most important loads.
- how to build a 72‑hour solar backup kit
- how to prepare a solar‑powered emergency backup system
- how to reduce power consumption during an outage
Best Emergency Battery Backups
These buyer pages focus on systems designed specifically for outages, medical continuity, and multi‑day preparedness.
Solar Integration for Long Outages
Solar is the only way to extend runtime beyond the watt‑hours you start with. These guides explain how to size and configure solar for emergency use.
- how to size a solar generator
- how to calculate solar battery storage needs
- how to build an off‑grid solar power system
Emergency Preparedness FAQ
How much power do I need for a 72‑hour emergency?
Most households need between 1,000–3,000 watt‑hours to cover communications, refrigeration, and medical devices for 72 hours. The solar kit and storage guides above walk through exact calculations.
What devices should I prioritize during an outage?
Start with health and safety: medical devices, refrigeration, heating controls, sump pumps, and communications. Everything else is optional.
Do I need solar for emergency preparedness?
Not required, but highly recommended. Without solar, you’re limited to the watt‑hours you start with. With solar, you can extend runtime indefinitely.
How do I keep Wi‑Fi online during a blackout?
Use a small battery backup or power station sized for your modem and router. The Wi‑Fi outage guide above includes runtime math and recommended setups.
What’s the simplest emergency power setup?
A 300–600Wh power station + a 100–200W solar panel + a written 72‑hour load plan. The guides above show how to build it.
