We tried three torch-radio combos. Two of them had both solar- and dynamo-charging options, so the dynamo could provide a back-up if the solar ran low.

The third (and most expensive) model was dynamo only (a Digitech brand from Jaycar Electronics). It took a few minutes of winding to get the radio going … only to have it peter out soon after. The instruction manual said you could charge the device by plugging it into the mains (although an adaptor wasn’t included). A full charge by this method took 12 hours!

By comparison, the two solar/dynamo models gave us solar-powered sound with no effort. We got reasonable reception (and torch light) from both. The Eton Microlink ($64.95) gave us superior sound compared with the other unbranded solar/dynamo model ($39.95). The sound quality of the Eton Microlink was similar to a battery-powered transistor.

Of the two, the Eton Microlink was the most compact. You could hold it easily in the palm of your hand and it would tuck away nicely in a picnic basket or backpack. It’s designed to provide up to three hours of radio play when fully charged.

The unbranded solar/dynamo model was bigger and could also use AA batteries.
