If half your waking life seems to be spent plugging your iPod into the wall, you're not alone. Ours rarely seems to be away from the mains, which led us to thinking: how much money are we burning to listen to our tunes? And how much carbon are we simultaneously burning? Scientific answer: too much. That's why we love this renewable and money-saving solution, the Solio solar iPod charger. We've used one in the past and it does what it says on the tin, albeit a touch slowly in the UK. If you're struggling to justify the £60 asking price, tell yourself it's worth it for the lovely design and its ability to charge mobile phones via adapters.
