Sometimes it is the simple things that take the longest time. As a race we have sent people to the moon, we can communicate via satellite, we have GPS and we can call someone on the other side of the planet… But could we agree on a simple thing like a phone charger. No. Every phone has a different charger, even different models from the same manufacturer have different chargers. But now, at last, after what seems like decades of mobile phone use, a new mobile phone charger that will work with any handset has been approved by the International Telecommunication Union (ITU).
