How to Prepare for a Power Outage: The Complete Checklist
Power outages are the most common disaster in the world—more common than floods, fires, and storms combined, because all of those cause outages too. The good news: unlike most disasters, an outage is almost entirely survivable with preparation you can finish this weekend. This is the complete checklist, organized around the four pillars that apply in every country. New here? The global outage picture explains why this keeps happening.
Pillar 1: Know Your Risk
Your outage type determines everything else. Two questions:
How often? Daily-or-weekly outages mean structural load shedding (South Africa’s version) or an unreliable local grid. Once-or-twice-a-year outages mean event-driven storms (hurricanes, winter storms, California’s PSPS).
How long? Under 12 hours favors a power station and a stocked pantry. Multi-day events favor solar recharging, generators, and a fuller kit.
Pillar 2: Build the Kit (72 Hours)
The standard everywhere is 72 hours of self-sufficiency—that’s how long restoration can take after a major event. The universal kit:
Water & food
- ☐ Water: 1 gallon (4L) per person per day × 3 days
- ☐ Food that needs no cooking (canned, bars, dried)
- ☐ Manual can opener
Light & information
- ☐ Headlamp per person (better than flashlights—hands free)
- ☐ Battery or hand-crank radio
- ☐ Power bank, charged
- ☐ Spare batteries in common sizes
Health & home
- ☐ First-aid kit
- ☐ 7+ days of prescription medications
- ☐ Battery-powered CO detector (if you own any fuel-burning gear)
- ☐ Cash (ATMs die with the grid)
- ☐ Hygiene supplies, baby/pet needs
Pillar 3: Sort Out Backup Power
This is the pillar most people skip—and the one that pays for itself the first night. The short course:
Size by watts and watt-hours. Watts = can it run your device (fridges spike 800–1,200W at compressor start). Watt-hours = how long (≈7 hours of fridge per 1,000 Wh). Run your own numbers in 30 seconds with our calculator.
Match the tool to your outage. Short frequent outages → a 1 kWh power station as an always-on UPS. Storm country → 2+ kWh with a solar panel (solar guide). Daily load shedding → lithium inverter sized for your worst day (inverter guide). Full guide with picks at every budget: best portable power stations. Multi-day events: generator vs power station. Cheapest first win: a UPS for the router and fiber. Light for less still: rechargeable outage lights. Food rules: how long food lasts without power.
The fuel rules (life-safety): generators run outdoors, 20+ feet from the house, never in garages. Never heat with gas ovens. CO kills after almost every major outage.
Pillar 4: Have a Plan
The kit is stuff; the plan is behavior. Thirty minutes of thinking now saves hours of chaos later:
- Who to call: utility outage number (saved), one out-of-area contact (local lines jam)
- What stays powered: priority order—medical devices → phones/network → fridge → everything else
- Where’s the gear: everyone in the house knows where the kit, flashlight, and power station live
- When to leave: decide in advance what would trigger evacuating (extended outage + extreme heat/cold, medical equipment failure)
- Practice once: kill the main breaker for an evening. Everything you forget is a bug found for free.
When the Power Goes Out: The 60-Second Drill
- Confirm: breaker box → utility outage map → report
- Fridge and freezer closed (4h / 48h full / 24h half-full—toss perishables above 40°F/4°C for 2h+)
- Backup power to essentials: medical → phones → fridge
- Unplug sensitive electronics (surges on restoration)
- One phone on low-power mode = designated “radio”
The Bottom Line
Preparation follows the same math everywhere: know your risk, hold 72 hours of life support, own the right amount of backup power, and rehearse the first minute. Pick the guide for your situation—hurricanes, winter storms, PSPS, load shedding—and start with one pillar this weekend. The grid will do its thing either way; the difference between an emergency and an inconvenience is you.
