If the power just went out, you have a short window to protect your home’s most vulnerable systems before food spoils, pipes freeze, or a basement floods. Here’s the priority order to follow, and what to plug in first if you have a generator or power station ready.
Priority 1: Anything Actively Preventing Damage
Before anything else, get power to systems that prevent active damage from occurring:
- Sump pump — a basement can flood within hours during a storm-related outage
- Well pump (if you’re on well water and expecting a fire risk or need water for other emergency needs)
- Sump pump battery backup charger, if you have one, so it’s ready if the primary fails
Priority 2: Medical Devices
If anyone in the household depends on a CPAP, oxygen concentrator, or other medical device, that takes priority over convenience items like TVs or non-essential lighting.
Priority 3: Refrigeration
A full refrigerator can typically stay safe for about 4 hours unopened; a full freezer can hold for 24-48 hours. If your outage looks likely to extend beyond that window, prioritize the fridge next.
Priority 4: Communication and Light
Keep a phone charger, a battery or hand-crank radio, and basic lighting powered so you can track outage updates and safely move through your home after dark.
What to Plug In With Limited Power
If you only have a small power station rather than a full generator setup, a surge protector power strip like the APC 6-outlet model lets you safely run multiple priority items (phone charger, radio, a lamp) from a single outlet without overloading the unit.
For safely distributing generator power to multiple rooms, a heavy-duty generator extension cord rated for outdoor use, like a 12-gauge 25-50 foot cord, prevents voltage drop and overheating that can occur with a standard household extension cord under generator load.
To stay informed during the outage itself, a hand-crank/battery combo emergency radio such as the Midland ER210 provides weather alerts and doesn’t depend on your phone’s battery holding out.

Quick Reference: What to Plug In First
| Priority | Item | Why |
|---|---|---|
| 1 | Sump pump | Prevents flooding damage |
| 2 | Medical devices | Health and safety |
| 3 | Refrigerator/freezer | Food safety window is limited |
| 4 | Phone charger + radio | Stay informed, call for help if needed |
| 5 | Basic lighting | Safety moving through the home |
Common Mistakes to Avoid
Plugging in everything at once. Overloading a generator or power station can trip its overload protection or damage the inverter — power up priority items first, then add others gradually.
Forgetting the sump pump until water is already rising. If you’re in a flood-prone area, sump pump power should be your first move, not an afterthought.
Using indoor extension cords for generator power. Standard household cords aren’t rated for outdoor generator loads and can overheat — always use a rated outdoor/generator extension cord.
Opening the fridge or freezer repeatedly “to check.” Every time you open the door, you shorten the safe window before food spoils.
FAQ
What should I plug in first during a power outage?
Prioritize anything preventing active damage (sump pump), then medical devices, then refrigeration, then communication and lighting.
How long can a refrigerator go without power?
About 4 hours unopened; a full freezer can typically hold safe temperatures for 24-48 hours if left unopened.
Can I run my whole house off a small power station?
No — a small power station (under 1,000Wh) is best reserved for priority items like medical devices, communication, and light. A full generator with a transfer switch is needed for larger loads like a well pump or furnace blower.
Is it safe to use a regular extension cord with a generator?
Standard indoor cords aren’t rated for outdoor generator loads and can overheat. Use a 12-gauge or heavier outdoor-rated extension cord.
