How to charge a phone without electricity, and what to do when the phone stops

Last reviewed: 12 November 2026. We are not an official body. We report what official sources say, and we list each source at the foot of the page.

The short answer

The step that costs nothing comes first: charge every device before bad weather arrives. With the mains power off, official bodies name a few ways to charge a phone: a power bank that you charged earlier, a charger that plugs into a car, and some solar radios that can also charge a phone.

To make the charge last, use the phone less and turn on its battery saver or low power mode. No official page that we read gives a run time for a power bank. Our power outage planner works out a range from the figures on your own power bank and phone.

A phone can also stop because the network is down or busy. For that, official bodies point to a text in place of a call, a paper list of numbers, an agreed meeting place and a little cash.

How to charge a phone without electricity

Charge every device before bad weather arrives. Ofcom in the United Kingdom, Ready.gov in the United States and the Government of Ontario each say to keep devices charged.

No official page that we read gives a run time for any charger or describes a home-made charger, and we do not pick products. These are some of the ways that official bodies name.

A power bank

A power bank is a battery that you charge from the mains and carry with you. Ofcom, the United Kingdom communications regulator, says that one can recharge your devices if severe weather lasts a long time. Get Ready Queensland says to pack one that is fully charged. Keep it topped up, because it only helps if it was charged before the power went off. Our power outage planner works out how many charges yours may give, as a range.

A car

ESB Networks in Ireland says that you may be able to charge a mobile device in the car. New Zealand's emergency agency suggests a USB phone charger that plugs into the car's power outlet, and Ready.gov says to keep a portable phone charger in the car.

A solar or battery radio

New Zealand's emergency agency says that some solar and battery radios can also charge a phone. We read no official page that describes a wind-up charger for a phone, only wind-up radios.

A public place

Ofcom says that a local council might list public spaces, such as libraries or community hubs, that might help with charging.

How to make a phone battery last in a power cut (power outage)

Once the power is off, the charge in the phone is all you have until you can charge it again. Official bodies give a short list.

  • Use the phone less.
  • Lower the screen brightness and turn on battery saver mode.
  • Switch to low power mode or aeroplane mode (airplane mode).

What stops when your phone stops

A phone does many jobs in a home. The United Kingdom government's Be Ready site says that people rely on phone and internet services for work, healthcare, banking and staying in touch, and that in the most serious cases the mobile phone, the landline and the broadband could all be down together.

  • Calls and messages. Ready.gov says that mobile networks can become overwhelmed in an emergency, which makes it hard to make and get calls.
  • Contacts. If the phone loses power, you cannot read the numbers stored in it.
  • Payments. Payment apps on a phone may be disrupted.
  • Maps. Be Ready says to download or print maps so that you can find your way with no internet.
  • Alerts and news. Ready.gov calls the smartphone a vital tool for emergency alerts. Be Ready says that updates may come by radio during an outage.

Text when a call will not connect

In an emergency many people use their phones at the same time, and calls may not connect. Ready.gov says that a text message needs less of the network and gets through more reliably. Ofcom and the Government of Ontario also say that a text may get through, and Be Ready says that messaging may work even when calls do not.

Emergency contact list template: what to write on paper

A paper list still works when the phone has no power. Official bodies name these lines for it.

  • Family, neighbours, your doctor and your utility companies.
  • Your broadband and mobile providers.
  • A contact who lives outside your area. PreparedBC in Canada says that the list should include one, in case local networks are overwhelmed. Ontario says to choose someone far enough away that the same emergency is not likely to affect them.
  • A meeting place. Ready.gov says to choose one that is familiar and easy to find. PreparedBC gives a community centre as an example.
  • The emergency numbers for where you live. They are in a table further down this guide.

Keep the list somewhere easy to find in a power cut, and give a copy to each person. Our printable contact card has a space for most of these lines.

Will a landline work in a power cut?

In the United Kingdom, Australia and New Zealand, the sources in the table say that digital home phones need electricity in the home, so they stop in a power cut unless they have a battery or another power source. What a provider must give you is not the same in every country we read.

United StatesReady.govFind out if your home phone works when the power is out, and how long its battery backup lasts.
United KingdomOfcomA digital landline runs on mains electricity, so it stops in a power cut unless it has a battery back-up. If you rely on your landline, your provider must make sure that you can still reach the emergency services in a power cut. If you also have no working mobile phone or no reliable mobile signal, the provider must offer you a free back-up, such as a battery unit for your home. In a power cut the back-up has to keep working for one hour or more. The back-ups of some providers last up to seven hours.
CanadaNot covered by the sources we list
AustraliaNBN CoAbout phones on the nbn network: no type of landline phone works in a power outage, because the network needs power both at the exchange and in the home. Even with a battery backup in the home, an outage may last longer than the battery life.
New ZealandCommerce CommissionThe home phone technologies that the Commerce Commission page covers need a power supply in the home, so in a power cut they stop unless they have their own separate power source. If you have no other way to contact 111 in a power cut, and you are at particular risk of needing the emergency services for health, security or disability reasons, you can apply to your provider.

Where a row has no line from the sources we list, ask your phone provider.

Ofcom notes that a mobile phone is a practical alternative for most people when the power goes out. That is one more reason to keep it charged.

Emergency numbers by country

The emergency number is not the same in every country. Write yours on the paper list. The Government of Ontario says to teach children how and when to call 9-1-1 and the other numbers they may need.

Emergency numbers, from each country's own official page
CountryOfficial bodyEmergency number
United States911.gov911.
United KingdomOfcom999 or 112. The call is always free and works even if you have no credit. If your mobile provider has an outage, your phone can use another provider's network to call these numbers.
CanadaOntario9-1-1, where available.
AustraliaAustralian GovernmentTriple Zero (000). It is the main emergency number in Australia, for situations that threaten life or cannot wait.
New ZealandNew Zealand Police; Commerce Commission fact sheetNew Zealand Police: 111 for Police, Fire and Ambulance. Calls are free. Commerce Commission: outside your own provider's coverage but inside another provider's, you can still call 111.
Ireland112.ie999 and 112. 112 works across the EU from any phone, free of charge.

Keeping some cash for when payments stop

Card machines, cash machines and payment apps can stop in a power cut or a network failure, so official bodies say to keep some cash at home. The pages in the table name no amount. Be Ready in the United Kingdom says that the amount depends on your family's needs for essentials.

Cash at home: what each country says

IndiaIndia Meteorological DepartmentThe India Meteorological Department lists cash and credit cards in a disaster emergency kit.

Outside the countries in the table, an amount is sometimes named. Sweden's central bank gives a benchmark of around SEK 1,000 in cash for each adult, and says that even a lower amount helps. A European Central Bank staff article reports that authorities in the Netherlands, Austria and Finland suggest about €70 to €100 for each household member, or enough for the essentials of about 72 hours. These figures are for those countries only.

Sweden's central bank also says to have more than one way to pay, so that you can still pay if one of them does not work.

Put it in your plan

Work out how long your power bank would keep your phones going, then print a contact card for each person in your home.
