Three ways: plug it in with the included USB cable, leave it in daylight so the built-in solar panel tops it up, or turn the hand crank whenever you need power right now – day or night.
Yes. The Cairn™ has a built-in power bank with a USB output. Plug in your usual phone cable and it charges like any portable battery. Keep it topped up in daylight and it's ready whenever you need it.
It's your back-up when there's no sun and no socket. A few minutes of cranking gives you enough power to listen to the radio, switch on the torch or get a little charge into your phone.
Real demos of the Cairn™ – radio, torch, solar and hand crank.
Here's the difference one small device makes when there's no socket around.

Small enough to forget in a drawer. Ready the moment you need it.
Most of us rely on one device to call, check the news and find our way. But a phone battery only lasts so long – and when there's no socket nearby, there's nowhere to plug it in.
That's exactly why we built the Tarnwild Cairn™: a compact back-up that makes its own energy, keeps you informed and lights the way.
A wind-up radio and a good torch are two things every home should have in a drawer.
The Cairn™ covers the essentials in one device: energy for your phone, a radio to follow the news and light in the evening.
No socket? No problem. Leave the Cairn™ on a windowsill and the solar panel quietly recharges it through the day.
At night, or under grey skies, simply turn the hand crank to generate power on the spot. And at home, a USB cable charges it in the usual way.
About the size of a smartphone and light enough to carry everywhere, the Cairn™ slips into a jacket pocket, a glovebox or a hiking pack.
Take it camping, on long walks or on the road – and bring it home to the kitchen drawer afterwards.
At home, the bright LED torch and the radio are easy for everyone to use – from the kids to grandparents.
One for the house, one for the car, one for Grandma: that's why so many customers choose a bundle.
Four essentials, one rugged device.
“The sound is incredibly clear! A few turns of the crank and it's up and running. The torch with several brightness levels is a really nice touch too. Blown away! I feel ready for anything now.”
“I was surprised by how well this little radio works. It's tiny – about the size of a hand – and really light! It's reassuring to have it with me wherever I go.”
“Works really well. Great value for money. One to take anywhere there's no signal. It gives you peace of mind.”
“The listing doesn't mention it, but the radio does have a signal alarm paired with the light! It makes me even happier I didn't go for another product that made a big deal of having one. I feel truly ready for whatever comes!”
We're confident the Cairn™ will earn its place in your home. Test every function – the radio, the torch, the solar charging. If you're not completely happy, return it within 90 days for a full refund.
