A winter storm that knocks out power is a different emergency than a car breakdown or a backcountry mishap — the core problem is keeping a household warm, lit, and informed for however long the outage lasts, without burning the house down trying. Here’s gear that actually matters, based on what emergency-prep guides consistently recommend.
1. An Indoor-Rated Propane Heater (With Ventilation)
The Mr. Heater Portable Buddy Propane Heater is the most frequently recommended outage heat source because it runs on a single small propane canister with no electricity or generator needed. It must always be used with a cracked window or door for ventilation and never run unattended overnight.
Pros: Reliable heat with no power required, widely available canisters.
Cons: Carbon monoxide risk if used without ventilation — never optional, always required.
2. A Carbon Monoxide Detector (Battery-Powered)
Any fuel-burning heater needs a working CO detector in the same room, full stop. A battery-powered unit like the Kidde Battery Operated Carbon Monoxide Detector keeps working even when the power that runs your hardwired detectors is out.
Pros: Critical safety layer, doesn’t depend on grid power.
Cons: Needs battery checks — don’t assume it’s ready if it’s been sitting in a drawer.
3. A Zero-Degree Rated Sleeping Bag
For fuel-free warmth, a quality Zero Degree Rated Sleeping Bag produces no carbon monoxide and needs no fuel at all, making it arguably the single safest warming tool for an extended outage, especially overnight.
Pros: Zero fire or CO risk, works indefinitely with no fuel supply needed.
Cons: Less practical than a heater for warming an entire room or moving around.
4. A Headlamp Per Person
A Black Diamond Spot Headlamp beats a phone flashlight for outage use because it leaves your hands free to cook, check a breaker, or carry a kid up the stairs safely in the dark.
Pros: Hands-free, long battery runtime, cheap enough to buy one per family member.
Cons: Needs spare batteries on hand to be reliable long-term.
5. A Hand-Crank NOAA Weather Radio
A Hand Crank NOAA Weather Radio keeps working with zero batteries or power, and knowing how long an outage is expected to last changes real decisions — whether to shelter in place, head to a relative’s house, or start conserving fuel more aggressively.
Pros: Works with no external power at all, gives decision-relevant information.
Cons: Only useful if local stations are actually broadcasting updates.
6. Mylar Emergency Blankets
A pack of Mylar Emergency Thermal Blankets is cheap, compact, and adds a surprising amount of retained body heat layered over regular blankets or sleeping bags during an extended cold stretch.
Pros: Extremely cheap, compact for storage, genuinely effective heat retention.
Cons: Not comfortable as a primary blanket — best as a supplemental layer.
7. A Portable Power Station
A Jackery Explorer Portable Power Station keeps phones charged, a CPAP machine running, or a small space heater’s control board powered during an extended outage, without the fumes, noise, or fueling needs of a gas generator.
Pros: Silent, no carbon monoxide risk, works indoors safely.
Cons: Limited total capacity compared to a fuel generator; needs to be charged in advance of a storm to be ready.
Safety Priority Order
If you only prepare for one thing, prepare for heat without fire or fuel risk first — a fuel-free sleeping bag plus layered blankets. Add a CO detector as a non-negotiable second item the moment any fuel-burning heater enters the house. Everything else on this list is about comfort and information, which matter, but matter less than not dying from preventable causes during an outage. Charge a portable power station and check flashlight batteries before a storm actually arrives, not after the power is already out, since forecasts for major winter storms are typically accurate enough 24-48 hours out to make last-minute prep genuinely effective rather than a scramble in the dark.
FAQ
Can I run a generator indoors during a power outage? No, never. Generators must run outdoors, far from windows and doors, due to carbon monoxide risk — this is one of the most common preventable winter storm deaths.
How much food and water should I keep on hand? Most emergency guides recommend 3-5 days of non-perishable food and water per person as a baseline for winter storm preparedness.
How long does a typical portable power station last on a single charge? Depending on capacity and what’s plugged in, a mid-size unit can keep phones and a few small devices charged for several days, though running anything heat-producing drains it far faster than just charging electronics.
Should I fill the bathtub with water before a storm? It’s a reasonable precaution if your home relies on a well pump that loses power during an outage, since stored water covers flushing toilets and basic needs if the tap stops running; city water systems are less likely to lose pressure during a power outage alone.
What’s the biggest mistake people make prepping for a winter power outage? Assuming the outage will be short. Treating every outage as if it could last several days, then being pleasantly surprised when it’s shorter, is safer than assuming a quick fix and being caught unprepared if it stretches on.
Do I need a carbon monoxide detector if I’m only using a sleeping bag and blankets, no heater? If no fuel-burning device of any kind is in use, the immediate CO risk is lower, but it’s still worth having a working detector in the house generally, since neighbors’ generator exhaust or a furnace malfunction during an outage can introduce CO from outside the room you’re sheltering in.
