This environmentally-friendly laptop charger means the end for your battery letting you down whilst working outside. In fact, to call it a ‘laptop charger’ does it a disservice, since it can also be used to charge pretty much anything, from your iPod to your mobile, with the use of the correct adaptor.

It appears reasonably large, which might rather put you off lugging it round merely to charge your iPod, but if there’s any reason you and your laptop need to be outside for a considerable length of time, this charger could well come in handy.
