This compact multifunctional device features a dual-function torch (single 0.5W LED or dual high brightness LEDs), FM radio and emergency siren.

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.
