Best wind-up solar radios UK (2026): crank radios with a solar panel, and what it really gives
Nearly every wind-up radio now carries a small solar panel on top, and the box tends to make it sound like free power. The makers' own manuals are more cautious. Every radio on this page has both a hand crank and a solar panel according to its maker or, for the marketplace brands, its Amazon listing, which we label. Only Technaxx, Sangean (for the MMR-88), Duronic and Midland put a number on the panel, and those numbers come in many hours of direct sun: Technaxx says up to 35 hours to fill the TX-414's battery, Sangean about 15 hours for the MMR-88. Where a maker gives no solar figure, the table shows a dash. We haven't used any of these radios ourselves, and prices and stock are refreshed on a schedule.

The most complete specification on this page from a brand that publishes its numbers. Philips states IP55, up to 60 hours of play from a user-replaceable lithium cell, a 3W speaker with a headphone socket and digital tuning with 40 presets, and it still runs on four AAA cells when that battery is flat. Two things hold it back. It's a new model with little owner feedback yet, and Philips' own page gives the battery as 5,200mAh in its spec table but calls it a 2,600mAh power bank elsewhere, so treat phone charging as a useful extra rather than a measured figure. At 670g it's a home radio, and there's no DAB.
Worth knowing: FM/AM only; no DAB+
Who shouldn't buy it: Don't buy it if you want DAB, or something light for a rucksack. For a grab bag the TAR1609 weighs 390g and the battery-only Roberts Sports 925 about 150g.

Most UK households: a mainstream-brand FM/AM set with its own rechargeable battery, three AAA cells as a fallback, and a crank and solar panel behind those.

Product prices and availability are accurate as of the date/time indicated and are subject to change. Any price and availability information displayed on Amazon.co.uk at the time of purchase will apply to the purchase of this product.Our verdict
The radio we'd put in a household kit first. Philips quotes up to 32 hours of listening from the built-in battery, it charges from the same USB-C lead as most modern phones, and it also runs on three ordinary AAA cells, so a flat internal battery doesn't leave you relying on the handle or the sun. There's no DAB, no headphone socket and no water-resistance rating, and Philips publishes no torch brightness or crank figure, but it does the one job GOV.UK asks of a radio, from a brand that publishes its specs, without an American weather band you can't use.
Worth knowing: FM/AM only, with analogue tuning: no DAB+, no presets and no headphone socket
Who shouldn't buy it: Don't buy it if you want DAB, or a radio that will properly charge a phone. Its USB-A port is an emergency top-up only, so keep a separate power bank.

Sangean's manual states the figures that matter: about 24 hours of play from a full 2,600mAh cell, about 3 hours to recharge by USB-C, and about 10 minutes of listening per minute of winding at 100 turns a minute. IP55 against dust and splashes is on the datasheet, and a 5V/1A USB-A port is a usable phone top-up. Against it: 900g, FM and AM only with no DAB+, and a built-in cell with no AA or AAA fallback, so when the cell is flat you depend on the crank or the sun.
Worth knowing: FM and AM only, with no DAB+ band
Who shouldn't buy it: Don't buy it if you want DAB+ or something light for a grab bag. The Sangean MMR-88 DAB+ is 377g with DAB+, and the Philips TAR1609 weighs 390g.
Read the full review →Budget-minded DAB+ listeners who want a colour screen and Bluetooth, and who'll treat the battery figure as a claim.
Our verdict
A marketplace DAB+ crank radio that owners rate for its DAB reception, including in weak-signal areas, with a colour screen, Bluetooth and a 57mm speaker. We list the 12,000mAh battery as a claim because nobody has verified it, the AAA fallback is something owners report rather than the listing states, and there's no crank figure at all. Treated as a DAB+ radio you charge from the wall, it's a sensible buy; treated as a 12,000mAh power bank, it's unproven.
Worth knowing: The 12,000mAh capacity is the seller's unverified claim, and there's no published crank-to-play figure
Who shouldn't buy it: Don't buy it if you're buying it for the battery figure. Judge it on DAB+ reception and the screen, and check the AAA fallback works on day one.
A light DAB+ set for a kitchen shelf or a bag that can be topped up by crank, sun or USB-C, if you accept a short run time.

Product prices and availability are accurate as of the date/time indicated and are subject to change. Any price and availability information displayed on Amazon.co.uk at the time of purchase will apply to the purchase of this product.Our verdict
Sangean publishes more than most brands here: its manual gives about 10 hours of play from a full charge, about 5 to 7 minutes of listening per minute of winding at around 120 turns a minute, and about 15 hours in direct sun to refill the cell. That makes it a believable, modest set. It's DAB+ and FM at 377g with a swappable 18350 cell, but there's no AA or AAA backup, no IP rating and the phone port is a 5V/0.3A trickle. For a longer run the Roberts SolarDAB 99 quotes up to 20 hours, at more than twice the weight.
Worth knowing: About 10 hours per charge, no AA or AAA fallback, and a specialist 18350 cell to replace
Who shouldn't buy it: Don't buy it if you want a long run time, an IP-rated body or a quick phone top-up. The Philips TAR3500 quotes up to 60 hours, with AAA backup, and the Sangean MMR-99 has a rated 1A port and a dust and water rating, though it has no DAB+.

A DAB+ and FM wind-up radio from a maker that publishes its figures, for a household that wants DAB in a power cut and will keep it topped up by USB-C.
as of 15 Nov 2026, 12:07 GMT · Details
Product prices and availability are accurate as of the date/time indicated and are subject to change. Any price and availability information displayed on Amazon.co.uk at the time of purchase will apply to the purchase of this product.Our verdict
One of the few DAB+ wind-up radios whose maker states real numbers. Technaxx gives up to 10 hours from the 2,000mAh cell, about 3 hours to recharge over USB-C, a 150 lux torch with an SOS mode and a USB-A port rated 5V/1A for a phone top-up. It is also honest about the backups: a full charge takes up to 6 hours of winding or 35 hours of sunlight, so the crank and the panel are last resorts. Its gap for a power cut is that it takes no AA or AAA cells and has no stated water rating, so once the cell and your power bank are flat the crank is all that's left. At 293g it suits a grab bag.
Worth knowing: No AA or AAA fallback: the 2,000mAh cell, the crank or the panel is all there is
Who shouldn't buy it: Don't buy it if you want a radio that runs on ordinary cells when its battery is flat. The Philips TAR3500 takes four AAA cells and the Acta Berg DAB+ crank radio three, and the Roberts Play 20 runs DAB+ on four AA cells with no crank at all.
A wind-up and solar set that also gets DAB+, for a home kit where BBC national stations on digital matter.

One of the few crank and solar radios on Amazon UK with DAB+ as well as FM, plus a 5,000mAh battery, a torch, an SOS alarm and a charging port in one 19cm box. Acta Berg publishes almost nothing beyond the listing: no battery life, no output rating for the charger, no weight and no dust or water rating, and the brand has no working website. Treat it as a capable-looking budget set, not a rated one.
Worth knowing: No published battery life, charging output, weight or IP rating; the brand has no working website
Who shouldn't buy it: Don't buy it if you want published figures. The Philips TAR3500 states IP55 and up to 60 hours from its lithium cell, and the Roberts SolarDAB 99 is a DAB+ wind-up from a UK brand.

Product prices and availability are accurate as of the date/time indicated and are subject to change. Any price and availability information displayed on Amazon.co.uk at the time of purchase will apply to the purchase of this product.Our verdict
A generic crank-and-solar radio with a 5,000mAh cell, AM, FM and shortwave bands and a phone-charging role. The only maker website that could be found is an empty placeholder, so every figure here comes from the Amazon listing, and that gives no run time, no crank figure and no USB output rating. No AA or AAA fallback is listed, so when the cell is flat you depend on the handle or the sun. It may well do the job, but nothing published lets us say how well.
Worth knowing: No maker documentation: the listing gives no run time, crank output, USB rating or AA/AAA fallback
Who shouldn't buy it: Don't buy it if you want published numbers or a battery fallback. The Philips TAR3500 quotes up to 60 hours with AAA backup, and the Sangean MMR-99 quotes about 24 hours of play and about 10 minutes of listening per minute of winding.

Mostly a power bank with a radio attached: a large internal cell for topping up phones through a long cut, with AM/FM and a Bluetooth speaker mode when you want sound.
Our verdict
Midland's manual gives a 10,000mAh cell, up to 100 hours of use (conditions not stated) and a USB-C port that outputs up to 3A, far more phone charging than most radios here offer. The catch is in the same manual: while it charges another device the radio drops to clock mode, so you can't charge and listen at once. For a cell this size the crank and solar panel are slow refills, with at best 10 minutes of recharge per hour of direct sun by Midland's figure. There's no DAB, no published IP rating and no AA fallback.
Worth knowing: The radio pauses while the unit charges another device, per the manual; AM/FM only, no DAB
Who shouldn't buy it: Don't buy it if you need DAB+, or want the radio to keep playing while it charges a phone. For DAB+ look at the Sangean MMR-88 DAB+ or the Nedis; the Philips TAR3500 adds an AAA fallback.

A power-cut standby for the hallway drawer: torch, loud siren, AM/FM and a battery that owners say will charge a phone, at a marketplace price.
Our verdict
A popular all-in-one that does the basics competently, with a brighter torch than most here. We've trimmed what we used to say about it: the 12,000mAh capacity is a seller's claim with no teardown behind it, the torch is 3W rather than 5W, and the siren is 116dB. It takes three AAA cells, which matters. One owner says a full day in the sun didn't move the battery level, so treat the solar panel as a slow extra, and shortwave is no help in a UK emergency.
Worth knowing: The 12,000mAh battery and '50+ hours' are unverified seller claims, and one owner says a day in the sun didn't move the battery level
Who shouldn't buy it: Don't buy it if you want DAB or a verified power bank. For DAB+ the CR1030DAB is the better ROCAM; for running times a manufacturer stands behind, look at the Philips sets.
A pocket-sized DAB+ radio with crank and solar backup and a swappable 18650 cell, from a European electronics brand that publishes a proper manual.
Our verdict
Nedis states 15 hours of play from the 2,500mAh cell and 3 to 5 minutes of radio per minute of cranking, a modest figure, and its manual shows how to swap the 18650 cell. It's DAB+ and FM at 288g, with a torch, reading light and siren. The loose ends are real: no headphone socket, a 1W mono speaker, no published rating for the USB-A output so phone charging is unproven, no IP rating (the manual says to keep it dry), and a manual whose crank line ('around 3 to 5 minutes to fully charge') doesn't match the product page's figure.
Worth knowing: No headphone socket, a 1W mono speaker and no rated phone-charging output
Who shouldn't buy it: Don't buy it if you want a water-resistant set or a rated phone-charging port. The Sangean MMR-99 has both, a dust and water rating and a 5V/1A USB-A port; the Philips TAR3500 is rated for dust and water but gives no USB output rating. Neither has DAB+.

A cheap AM/FM backup with an AAA fallback and USB-C, for a grab bag or the car.
Our verdict
Still a sensible budget pick because it gets the fundamentals right: AAA cells as a fallback, USB-C charging and a limited lifetime warranty. Be clear-eyed about the rest. The torch is a 20-lumen glow, the 2,000mAh cell gives a phone a top-up rather than a charge, the NOAA band is silent here, and the big review counts quoted for it in some UK blogs come from the US listing, not the UK one.
Worth knowing: The torch is 1W/20 lumens, which is dim, and the 2,000mAh cell is a phone top-up at best
Who shouldn't buy it: Don't buy it if you want useful light or a real power bank. Add a head torch and a separate power bank, or step up to the Philips TAR1609 for a longer-running radio with published figures.

A cheap all-rounder for a power-cut box: crank, solar and USB-C charging, a torch and a phone port in one pocket-sized set.
Our verdict
XHDATA is an established radio maker, and this is its wind-up model: a 3,000mAh battery that charges over USB-C, a hand crank and solar panel as backups, a torch and reading lamp, an SOS alarm and a USB port for a phone. AM tunes in 9kHz steps for UK medium wave. It has no DAB, and the listing gives no battery life, charging output, weight or dust and water rating. The weather band in its name is a US service, so ignore it here.
Worth knowing: No DAB, and no published battery life, charging output or IP rating
Who shouldn't buy it: Don't buy it if you listen on DAB. The Acta Berg DAB+ crank radio adds digital stations, and the Philips TAR3500 publishes its run time and an IP55 rating.

The cheapest way onto DAB+ with an AAA fallback, if you'll charge it from the wall and treat the crank and solar panel as extras.
Our verdict
On paper the budget DAB+ answer: DAB+, FM with RDS, 60 presets, a 5,000mAh cell and three AAA cells as backup, in a 410g IPX4 body. Owner reports pull it down. Two owners say the solar panel adds little or nothing, one says the promised automatic switch to AAA never happened and the radio just shut down, and one got under 10 seconds of radio from 15 minutes of winding, though their fresh AAA cells also ran flat within hours, which points to a faulty set. So charge it from the mains, keep AAA cells in it, and don't count on the handle.
Worth knowing: Two owners say the solar panel adds little or nothing, and one got under 10 seconds of radio from 15 minutes of winding, possibly from a faulty set
Who shouldn't buy it: Don't buy it if you expect the crank or the sun to run it. If you can't keep it charged from the mains, a battery-only set or the Philips TAR1609 is the safer buy.
A compact AM/FM set with a clock and a small torch for a drawer, glovebox or tent, from a UK company, if you accept a very small 300mAh cell.
Our verdict
A step up from the Duronic Hybrid on features: a three-LED torch and a clock with alarm, on a 300mAh cell Duronic rates for 7 to 9 hours of radio. Duronic says a minute's winding gives 18 to 27 minutes of radio and one owner says at least 20, so that roughly holds up. Its manual shows the limits: the torch is only 11 to 14 lumens, and phone charging works by winding, at 4 to 15 minutes of talk time per 3 minutes of cranking, enough for a call, not a recharge. AM/FM only, with no AA or AAA option listed, and one owner says the tuning needs tweaking quite often.
Worth knowing: A 300mAh cell with no AA or AAA option listed, and a 35 to 42 hour solar charge by Duronic's figure
Who shouldn't buy it: Don't buy it if you want DAB, a proper phone top-up or a battery fallback. The Philips TAR3500 has a USB-A port, AAA backup and a replaceable cell, and the Roberts Sports 925 runs on swappable AA cells, though neither has DAB.

Product prices and availability are accurate as of the date/time indicated and are subject to change. Any price and availability information displayed on Amazon.co.uk at the time of purchase will apply to the purchase of this product.Our verdict
A tiny, long-selling wind-up radio that does one thing: AM/FM from a crank, a solar panel or a USB lead. Duronic claims 20 minutes of play per minute of winding and one owner gets about 15, so the figure roughly holds up. There's no torch, no AA option and a 300mAh cell good for about 7 hours, and, despite the listing title, Duronic's own FAQ says it won't charge a phone. We've corrected our entry to say so.
Worth knowing: No torch, no AA/AAA fallback and a 300mAh cell: about 7 hours of listening, then it's sun or handle
Who shouldn't buy it: Don't buy it if you want light, DAB, a battery fallback or any phone charging. It's a backup radio in the strictest sense.

Before you buy
Read the solar figure in the manual, not the picture on the box.
Technaxx says the TX-414's panel takes up to 35 hours of full sun to fill its 2,000mAh battery, and rates the panel at a maximum of 60mA in full sunlight. Sangean says about 15 hours of direct sun fills the MMR-88's 850mAh cell. Duronic's Apex manual gives 35 to 42 hours to fill, and says an hour of sun at 500W/m² gives 20 to 30 minutes of radio; Duronic's Hybrid manual gives 20 to 30 hours to fill, and about 30 minutes of radio from 5 hours of sun. Midland says that under optimal conditions an hour of direct sunlight gives the ER300 Pro 10 minutes of recharge. Philips and Nedis give no solar figure, Sangean's English manual gives none for the MMR-99, and the marketplace listings give none.
Work out what those figures mean in a British winter.
The Met Office's UK averages for 1991 to 2020 are about 43 hours of bright sunshine in December and 48 in January, and about 172 in June. Spread over a month, that is just under an hour and a half of bright sun a day in midwinter and nearer six in early summer. On those averages, Sangean's 15 hours for the MMR-88 is about eleven days of December sunshine and Technaxx's 35 hours is more than three weeks, if the panel catches every minute of it (our arithmetic). In summer the panel is far more useful.
Charge it from the mains first, and keep it topped up.
The quickest way to fill these radios is a USB charger at home: Sangean says about 2 hours for the MMR-88 and about 3 for the MMR-99, Technaxx up to 3 hours for the TX-414, Nedis 210 minutes, Philips 3.5 hours for the TAR3500 and Midland about 5 hours for the ER300 Pro. Do it when you buy the radio and every few months after, and give the handle a turn now and then too: Duronic recommends monthly cranking of the Apex to keep its battery healthy.
Prefer a second backup: shop cells or a crank with a published figure.
When the sun is weak, the crank is the faster refill on makers' own numbers: Technaxx says up to 6 hours of winding fills the TX-414 against up to 35 hours of sun, and Duronic says a minute of cranking the Apex gives 18 to 27 minutes of radio. Sangean says a minute gives about 10 minutes on the MMR-99 and about 5 to 7 on the MMR-88. Better still is a set with a shop-battery compartment as well: Philips designs the TAR1609 for three AAA and the TAR3500 for four, while the FosPower and both CR1009-body ROCAM sets (the 1009Pro and the AM/FM/SW model) list AAA support on Amazon.
Put it where the sun reaches, within the maker's temperature range.
The panel only works in direct light, so a north-facing room won't do much. Before leaving a radio on a sunny sill, check the maker's operating range: Technaxx gives 0 to 40°C for the TX-414 and Midland -20 to +55°C for the ER300 Pro. For a shed or a car, look for a weather rating from the maker: Philips rates the TAR3500 IP55, and Sangean the MMR-99 IP55 (the FosPower and ROCAM listings claim IPX3 to IPX4, without a maker behind them).
For longer power cuts
A radio, torches and a power bank cover a short cut. If you want the fridge, the router or medical kit to keep going for longer, these are the three ways to do it.
A silent battery you can use indoors. Enough for lights, the router and phones through an evening, or a fridge-freezer on a bigger one.
For cuts that run into days. Petrol or dual fuel, outdoors only, never in a garage or shed: the exhaust carries carbon monoxide.
2 to 4 kWh that stays in the house, often with solar panels to top it up, for a long cut or a home that relies on power for medical kit.

We haven't charged, wound or listened to any of these radios ourselves, so nothing here is a hands-on result: each one is researched, not used. Every solar figure, crank figure and running time comes from the maker's own page, manual or data sheet (Technaxx, Sangean, Duronic, Midland, Philips and Nedis), read between 23 October and 14 November 2026, except where the only source is an Amazon listing (ROCAM, Acta Berg, XHDATA, FosPower), which we label. The winter sunshine figures are the Met Office's; turning them into days of charging is our arithmetic and is labelled as such. Where a maker gives no solar figure the table shows a dash rather than a seller's claim. No claim on this page rests on owners' reviews. Amazon prices and stock come from Amazon's API on a schedule, not from reading the page. When two products are close, commission can decide which one we pick. A clearly better product always wins.

Common questions
Do wind-up solar radios actually work?
Yes, but the panel is slow. On makers' own figures it takes many hours of direct sun to fill the battery: up to 35 hours for the Technaxx TX-414, about 15 for the Sangean MMR-88 and 35 to 42 for the Duronic Apex. The crank and a USB charge from the mains are much quicker. Treat the panel as a way of topping up during a long cut, not as the main supply.
How long does a solar crank radio take to charge in the sun?
Where makers say, between about 15 and 42 hours of direct sun for a full charge: Sangean about 15 hours for the MMR-88, Technaxx up to 35 for the TX-414, Duronic 35 to 42 for the Apex. Shorter spells give a little listening: Duronic says an hour of sun at 500W/m² gives the Apex 20 to 30 minutes of radio, and Midland says an hour of direct sun gives the ER300 Pro 10 minutes of recharge. Philips, Nedis and the marketplace brands give no figure.
Will a solar radio charge in a UK winter?
Slowly. The Met Office's 1991 to 2020 average for the UK is about 43 hours of bright sunshine in the whole of December, just under an hour and a half a day. At that rate a panel that needs 15 hours of direct sun would take about eleven days to fill the battery, and one that needs 35 hours more than three weeks. Charge it by USB before winter and use the crank when you need power.
Is solar or wind-up better on an emergency radio?
The crank, when you need power soon. Technaxx says filling the TX-414 takes up to 6 hours of winding against up to 35 hours of full sun, and Duronic says a minute of cranking the Apex gives 18 to 27 minutes of radio, about what an hour of sun gives it. The panel's advantage is that it needs no effort, so it suits a radio left on a sunny sill in a long summer cut. Having both, plus ordinary cells where the set takes them, is the safest combination.
