No Power, No Gas, No Banking: Could You Last a Week?

A single power outage is manageable: you wait it out, the lights come back, life resumes. The harder question is what happens when power, gas, and banking all go down at the same time, for a full week. It's not as far-fetched as it sounds: a major grid failure can knock out electric gas-station pumps the same hour it takes down the card networks and ATMs that most households rely on for cash. When that happens, the things that normally bail you out: a quick store run, a hot meal, a tank of gas, a debit card swipe: aren't available either. This guide walks through exactly what to stock and do so a full week without any of those systems is an inconvenience, not a crisis.

Key Takeaways

• When the power goes out at scale, it often takes the payment network and gas pumps down with it: plan for all three failing together, not just the lights.
• Stock canned and ready-to-eat food, not just dry goods: rice, pasta, and dry beans are cheap calories, but they're useless without a working stove and clean water to cook them in.
• A charged solar power bank or solar panel is the one piece of gear that keeps working every single day of a week-long outage, with no fuel to run out.
• Keep enough physical cash on hand to cover a week of essentials: card readers and ATMs both depend on power and network connectivity that may not be there.
• Fill your gas tank and any portable fuel containers at the first sign of trouble: most gas station pumps are electric and stop working the instant the power does.

Why "No Power" Often Means "No Everything"

Most people plan for a power outage as an isolated event: the lights go out, you grab a flashlight, you wait. But electricity is the thing almost every other system quietly depends on. Gas station pumps are electric, so when a substation goes down, the pumps at every station on that grid go down with it, regardless of how much fuel is sitting in the underground tanks. Card payment terminals and ATMs need both power and a live network connection to authorize a transaction: when either one drops, "contactless pay" and "cash machine" both stop working at the same moment. Grocery store registers, pharmacy systems, and even some home security and medical-alert systems run on the same dependency chain.

This is why a genuinely resilient plan treats a power failure as a multi-system event rather than a single inconvenience. It doesn't require an exotic scenario: a severe winter storm, a major grid failure, or a regional infrastructure disruption can all trigger the same cascading effect. For more on the infrastructure side of this risk, see our National Grid Power Outage Risk guide and our Cyberattack Preparedness guide, which covers what happens when the disruption originates in the network layer instead of the power lines.

Day-by-Day Survival Priorities

You don't need to solve every problem on day one. The table below breaks a 1-week outage into three phases so you know what actually needs your attention first.

Food: No-Cook Canned Food

Most emergency food advice defaults to "stock rice, pasta, and dry beans," and those are genuinely cheap, calorie-dense staples. But they share one requirement that this scenario takes away from you: a working stove and a reliable source of clean water to boil them in. If your gas is also out, or you're conserving water, dry staples become dead weight in your pantry. The fix is simple: build the core of your week-long supply from food that's ready to eat straight from the container, hot or cold.

Best No-Cook Canned & Ready-to-Eat Foods

If you do have a way to boil water safely (a camp stove, for example), dry staples become useful again as a backup. But build your first line of food supply around the no-cook table above, since it works regardless of whether you have functioning heat. For a complete non-perishable shopping list beyond this table, see our Non-Perishable Food List and Best Emergency Food Supply guide.

Minimum 1-Week No-Cook Food List (Per Person)

• 7+ cans of protein (chicken, tuna, beans, or Spam)
• 7+ cans of fruit or vegetables
• 1 jar of peanut butter or other nut butter
• 1 box of whole-grain crackers
• 2-3 ready-to-eat meal pouches for variety
• Manual can opener (check you own at least one that doesn't need power)
• Disposable plates, bowls, and utensils to avoid using limited water on dishes

Water for a Full Week

FEMA and the Red Cross both recommend a minimum of 1 gallon of water per person, per day, which covers drinking and basic hygiene. For a full week, that means stocking and planning around the amounts below.

Municipal water often keeps flowing during a power outage since water towers rely on gravity, but extended multi-system failures can also disrupt water pumping infrastructure. A WaterBOB bathtub bladder is a simple, cheap way to secure 100 gallons the moment trouble starts, before pressure has a chance to fail. For the complete storage, container, and purification breakdown, see our Emergency Water Storage Guide.

Hygiene & Sanitation When Water Is Limited

If you're rationing drinking water, washing dishes and bathing the normal way are off the table, which is exactly where water-free hygiene supplies carry the week. This category gets overlooked in most emergency plans, but running out of it mid-outage is a genuinely miserable, avoidable problem.

• Disposable plates, cups, and utensils: eliminates dishwashing entirely, which matters when every gallon is accounted for
• Wet wipes: the closest substitute for a shower when water is rationed; stock far more than you think you'll need
• Hand sanitizer: keeps hand hygiene up without using water you need for drinking
• Sanitary pads and tampons: stock extra beyond a normal cycle's worth; stress can shift timing, and stores may not be reachable or open
• Heavy-duty garbage bags: for waste if sewage or trash pickup is also disrupted; also doubles as an improvised toilet liner
• Extra toilet paper: an easy one to run short on when you can't just run to the store mid-week

For full sanitation planning beyond this week-long scope, including what to do if plumbing itself fails, see our Sanitation & Hygiene Kit guide.

Power: Solar Chargers That Keep Working

A charged power bank gets you through day one or two. After that, the only realistic way to keep phones, radios, and small devices running for a full week without grid power is a renewable source: solar. Unlike a generator, a solar panel doesn't depend on a fuel supply that can run out, and unlike a battery-only power bank, it recharges itself every day the sun is up.

For most households, a solar power bank or foldable panel is the single best dollar-for-dollar purchase for a week-long outage: it's small, inexpensive compared to a full power station, and it's the one item on this list that keeps working indefinitely. See our full comparisons in Best Solar Power Banks and Best Solar Generators if you want to step up to a larger system.

Banking & Cash: When Cards and ATMs Go Down

This is the piece most emergency plans skip entirely. Debit and credit card terminals need both electricity and a live connection to the card network to approve a purchase; ATMs need the same two things to dispense cash. When a regional power failure also takes down local internet and cell infrastructure, as it often does, both systems can go dark at the same time, in the same stores where you'd normally go buy supplies. Physical cash, by contrast, works regardless of what the power grid or payment networks are doing.

Keep this cash in small bills: a $100 bill is hard to break when a cash-only store is also working with limited change. Store it somewhere secure and fireproof, not just in a kitchen drawer. For the full breakdown on denominations, storage, and security, see our Emergency Cash Guide.

Staying Informed Without Power or Signal

A battery or hand-crank NOAA weather radio is the most reliable way to get official updates when cell towers lose backup power, which typically happens after 4-24 hours depending on the tower's battery reserve. Conserve phone battery by enabling low-power mode immediately and checking it only at set intervals rather than constantly. For a full comparison of radios built for exactly this scenario, see our Best Emergency Radios guide.
