IEC Finalizes MicroUSB Charging Spec for Phones
Feb 1, 2011, 9:08 AM by Eric M. Zeman
The International Electrotechnical Commission has finalized specification IEC 62684, which sets the technical details of how chargers are to be made for mobile phones. The spec mandates the use of microUSB ports for charging purposes, and sets the power requirements that manufacturers should adhere to for interoperability across brands and handsets. Fourteen different handset makers collaborated with the IEC to help finalize the spec, including Apple, Nokia, Research in Motion, Emblaze Mobile, Huawei Technologies, LGE, Motorola Mobility, NEC, Qualcomm, Samsung, Sony Ericsson, TCT Mobile (Alcatel), Texas Instruments and Atmel. The IEC believes that the specification will lead to saved resources across the board, as handset makers won't have to ship chargers with each and every device, and won't have to make multiple different chargers for their different devices. The IEC also believes the spec will help lower the cost of chargers to consumers, as well as help reduce CO2 omissions. Some manufacturers, such as Nokia, have already chosen microUSB as their standard charging port.
