The first cell phone has been invented on April 3, 1973 by Martin Cooper, a Motorola researcher and executive and the first commercial citywide cellular network was launched in Japan by NTT in 1979, but the most unfortunate thing is: There’s no any inventor that want to invent the universal charger for the cell phone in the past 30 years!
Yeah, it sounds a little bit sarcasm here, but this is the truth! However, the situation is about to change, where the GSMA trade association has brokered a deal with the world’s leading handset makers at the 2009 Mobile World Congress. The final agreement of the topic is they’ve agreed to come up with an universal cell phone charger.
In this case, the entire major handset makers, such as Motorola, Nokia, Sony Ericsson, Samsung and LG have decided to use the “Micro-USB technology” as the common universal charging interface. In the meanwhile, the GSMA has promised that by 2012, almost every cell phone will use the same kind of connector to charge their cell phone’s batteries.
After all, it’s a win-win situation, either for the manufacturers or consumers!
