There are many varieties of mobile chargers out there, but this is about the most compact, ludite friendly designed one we've ever seen. Consisting of a sleek blue metal tube, you simply pop in an AA battery and plug it into your phone for an extra two hours talk time. It's so simple, you can get hold of an AA battery no matter where you are on the planet, it's small and smooth and comes with four different adaptors, so will charge a whole host of different phones.
Excellent idea! I want one of those!
