All are powered from an internal battery, which can be recharged via USB, or by cranking the dynamo handle. There’s a USB charging outlet to provide critical power to your phone in an emergency too. If you find yourself with nothing but hand-power, the dynamo will give you over 10-minutes of radio or torch functionality, or two minutes of siren. Of course, on a full charge they’ll run for much longer.
