Using the USB connector for charging mobile phones already allows to some extent to solve the problem of interoperability between devices of different models, as well as to ensure the continuity and universal power supply.
However, further progress in phones USB charging is not moving. USB 2.0 Cable powered device are capable of up to 2.5 W, USB 3.0 cable raises the ceiling to 4.5 watts, and only a special version of USB BC 1.2 interface provides power for devices up to 7.5 w .Intel in collaboration with other stakeholders USB-IF is trying to increase the performance of power devices that can be powered from a USB cable.
Thus, the specification USB PD (power delivery) provides power to the USB cable for handheld devices up to 10 watts, tablets and peripherals up to 18 watts, light notebooks up to 36 W, average laptops up to 60 W, and monitors and all in one PC up to 100 watts.
Intel will support the initiative with Hewlett-Packard, Intel, Microsoft, Renesas Electronics, ST-Ericsson, Texas Instruments and Nokia. The first devices with USB PD will appear at the end of this year. Related Products :
