The European Union on Wednesday formally established its micro USB charging standard for phone charging. The approach proposed over a year ago will guarantee that phones and phone chipsets from at least 14 companies, including Apple, LG, Motorola, Nokia and RIM, will support charging over a micro USB connection without needing to switch chargers. The measure was implemented to cut back on both wasted chargers and to let users switch chargers without risking damage or undercharging.
