It wasn’t long ago that most mobile phones had their own specialized chargers with their own proprietary interfaces, but in the past year or two, the majority of smart phone makers have standardized on micro USB for power. This standardization is great for users, because you can grab any micro USB cable you have lying around or buy at the store and attach it to your phone, without wondering whether it will work with you for phone. It’s great for the environment too, because the charger you get with today’s smart phone will work with your next phone and the phone after so you don’t have to throw it out.
Unfortunately, there’s no common standard for notebook power bricks, but that could be changing. According to a DigiTimes report, several Taiwanese vendors, including Acer and ASUS, and major manufacturers like Quanta, Compal, Wistron, Pegatron, and Inventec support the idea, which is being pushed forward by the IEEE (Institute of Electical and Electronics Engineers).
