Wind up radios have climbed Google’s UK searches because they sit on the government’s list of items for a three-day emergency kit. A radio that needs no mains power or fresh batteries is cheap insurance, but only if you buy the right kind.
Key takeaways
- Government guidance asks households to be ready for 3 days at home, and lists a battery-operated or wind-up radio.
- A hand crank charges a small battery or spring, so you can hear updates during a power cut.
- FM uses far less energy than DAB, so check that the radio picks up FM.
- Solar panels and USB outputs are useful extras, not essentials.
Why is everyone searching for wind up radios?
News outlets including the BBC have been running explainers on what to stock at home, such as the piece headlined Why should I stockpile and what will I need? A radio is one of the quieter items on that list, so people look it up.
The advice itself is not new. The government’s Be Ready site says being ready for 3 days helps you cope until support reaches those who need it. When the earlier “prepare” website launched in May 2024, LBC reported that the home kit list included a battery-operated or wind-up radio plus spare batteries. Then-Deputy Prime Minister Oliver Dowden called it “sensible safeguards – not stockpiling”.
How do wind up radios actually work?
Turning the handle spins a small generator, a bit like a bicycle dynamo. That energy goes into a rechargeable battery or a wound spring, which then powers the speaker and tuner.
Think of it as a tiny water tank. Cranking fills it, listening drains it. The bigger the tank and the thriftier the radio, the longer you listen per minute of effort.
How long does a crank really last?
Manufacturer claims vary widely. Some listings promise around 30 minutes of listening per minute of winding, while others claim far less. Treat those figures as best case.
Independent testing is blunter. A Stuff.tv review of a Freeplay model found that a couple of minutes of winding gave only about five minutes of DAB reception. DAB (digital radio) needs more power than FM, the analogue band, so FM is the sensible mode in an emergency.
What should you look for before you buy?
| Feature | Why it matters | Must-have? |
|---|---|---|
| FM tuner | Lowest power draw, widest reception | Yes |
| Hand crank | Works with no sun, no mains, no spare cells | Yes |
| AA battery option | A backup if the crank fails or you are tired | Strongly advised |
| Solar panel | Slow top-up on a bright windowsill | Nice to have |
| USB output | Emergency phone charge, though a crank gives little | Nice to have |
| Built-in torch | Saves carrying another item | Nice to have |
Opinion: skip the gimmicks and buy on the first two rows. A phone charger built into a crank radio is slow, and your phone will draw more than a few minutes of winding can supply.
Where does a radio fit in a 3-day kit?
According to the LBC list of the government advice, the kit also includes:
- a paper list of emergency contact numbers in case your phone loses power;
- a battery-operated or wind-up torch;
- essential medication and a first aid kit;
- 3 days of bottled water and ready-to-eat food that will not spoil;
- copies of important documents in a waterproof bag, and spare keys.
The radio matters because mobile networks and broadband can fail when the power does. Broadcast radio still works with a small receiver, so you can follow local updates from your council and emergency services.
Consumer expert Martin Lewis has also named a wind-up radio among sensible household items, reported by The Scotsman. He suggested that even one or two items are worth having if you cannot afford everything.
Do you need a power bank as well?
Probably yes. A charged power bank covers your phone far better than a crank can. Store it safely, and see our backpack charging safety rules for tips.
What happens next
Expect more explainers on household resilience and more retail interest in radios, torches and power banks. The official checklist can change, so check the Be Ready page for the current wording rather than relying on a headline or a retailer’s “emergency bundle”.
Buying one radio and a few tins is not panic buying. It is the scale the guidance describes: three days, not three months.
FAQ
Do wind up radios need batteries?
Not always. Many use a built-in rechargeable battery or spring charged by the crank, though most models also accept AA cells as a backup.
Is FM or DAB better in an emergency?
FM. It draws less power, so a short crank lasts longer. One Stuff.tv test found DAB gave only about five minutes from a couple of minutes of winding.
Does the government require a wind up radio?
No. The advice lists a battery-operated or wind-up radio, so a normal battery radio with spare cells also meets it.
Next step: test your radio now. Crank it, find your local FM station and write the frequency on the casing, so you are not fumbling in the dark.
