Hymini Wind Turbine - £36.99
The smart money's on wind power
Solar chargers are a fantastic way of keeping those gadgets charged. The obvious problem that any festival goer knows is that sun can be a rare commodity at British festivals, so this wind charger could be a better bet.
Like any wind turbine it uses the worst of the summer weather to keep your gadgets charged up all weekend.
