The power just went out. Your fridge is warming. Your phone is at 12%. You have no flashlight, no water, and no plan.

That is the moment every emergency kit either earns its place or turns out to be a waste of shelf space. This guide covers what a good outage kit contains, which part most kits skip, and how to pair a kit with backup power.

Why Many Emergency Kits Fall Short

Many boxed kits are built to look complete on a product page. They can include food bars nobody wants, weak flashlights, and first aid kits that are mostly adhesive bandages.

A useful test: what would you actually reach for at 2 AM with no power and no way to order anything new?

The 5 Things Every Outage Kit Needs

1. Light that lasts more than one night. Headlamps free your hands. Keep spare batteries or a rechargeable option.

2. Water you can drink. Store enough for each person for the whole outage, or add a reliable filter. See our emergency water storage guide.

3. Food your family will actually eat. Choose items that need no refrigeration or cooking, and rotate them before they expire.

4. Communication that does not depend on cell towers. A battery or hand-crank NOAA weather radio is worth having.

5. First aid that covers real injuries. Cuts, burns and sprains are the usual outage injuries, not wilderness scenarios.

Build or Buy?

Building your own kit lets you choose every item and often costs less, but takes time: sourcing each item, checking compatibility and tracking expiry dates. Buying a pre-assembled kit saves that time. A sensible middle path is to buy a proper first aid kit and build the rest (light, water, food, radio) yourself.

Where to keep it: inside, near the door you are most likely to use, with a smaller set in the car. Check it every six months: batteries, food and first aid expiry dates. Make sure everyone in the house knows where it is.

Pairing Your Kit With Backup Power

A kit covers the first days. For longer outages you need backup power for the fridge, phones and medical devices. A power station sized for your essentials is the usual answer; see our guide to the best solar generators for home backup.

If you only do one thing today, put the kit together. It covers the immediate risks of the first three days.

🩹 The Part of Outage Prep Most Kits Skip

Kit lists always cover water, food and light. Few address this: in a widespread storm, you cannot count on an ambulance.

During large storm events, emergency response times can stretch, roads can be blocked by debris, and hospitals can be overwhelmed. FEMA’s preparedness guidance assumes you may need to handle a wound, burn or sprain yourself for the first 24 to 72 hours.

That changes what belongs in the kit. Many drugstore first aid kits are mostly adhesive bandages. An outage calls for wound closure, bleeding control, burn treatment and a way to splint a sprain, because the usual injuries are cuts from broken glass, burns from candles and camp stoves, and falls in the dark.

Choosing by household size

SurviveX lists first aid kits sized by household. Prices below are from its listings at the time of writing and can change:

Kit	Household	Price	Best for
Small First Aid Kit	1-2 people	$54.99	Apartments, car, go-bag
Large First Aid Kit	3-4 people	$120.99	Most households (250 components per the listing)
Large Pro	5-6 people	$150.99	Larger families (270 components per the listing)
Large Waterproof	3-4 people	$150.99	Flood-prone areas, boats, humid storage
Burn Care Kit	add-on	$31.99	Candle and camp stove burns
Zip Stitch Wound Closure Kit	add-on	$34.99	Cuts that might otherwise need stitches
Travel Medicine Kit	1-2 people	$31.99	Over-the-counter medications for travel and everyday emergencies

The Large kit is a sensible default for most households. Per SurviveX, it includes Zip Stitch wound closures, trauma shears, hydrogel burn gel, a CPR mask and a conforming splint, in labeled compartments grouped by use. In a dark house with a bleeding hand, labels matter.

Two things worth knowing before you buy

FSA and HSA. SurviveX states that all of its first aid kits qualify for FSA and HSA spending. If you have FSA funds that expire on December 31, this can be a useful way to spend them. Check your plan’s rules.

Shipping and returns. SurviveX lists free shipping on orders over $50, free returns and a lifetime warranty, and says orders ship within 12 hours.

The Final Word

A kit is only as good as its contents and whether you can find them in the dark. Cover light, water, food, radio and real first aid, keep it where you can reach it, and add backup power for anything longer than a few days.
