CTIA Mobile Device Power Standard: micro-USB


Standard South Korea has been doing it for quite some time. In Korea when you purchase a mobile phone, whether it be Samsung, LG or some other brand, you can interchange the power plug. The government pushed all mobile phone manufacturers to a single standard and all imported mobile phones must have this standard power connection too. Now, the US is headed in the same direction.

US Too The CTIA Wireless Association has stated that micro-USB will be the power standard for all mobile phones as well as other mobile devices. Say good bye to all of those proprietary power plugs but don’t do it just yet: this standard goes into effect in January 2012. The 3.5mm audio plug is also becoming a standard for earphones.
