Anyone who charges the mobile phone or surf the plate via USB will have noticed that it is faster to use a power adapter to the outlet than an available port on your computer. The reason is that USB is only rated for a few watts, but that it should now change with a new addition to the standard.
The USB power delivery specification goodwill enable Increased power delivery via USB cables and connectors, Expanding cable bus power capabilities in USB applications. The specification enables higher voltage and current to deliver power up to 100 Watts.
USB 3.0 Promoter Group reveals that the specification for USB Power Delivery should be addressed at the Intel Developer Forum in Beijing, which lasts for weeks.The addition allows for a withdrawal of up to 100 W via existing cables and connectors, which opens up new application areas.
Along with faster charging batteries can, for example to connect storage devices, monitors and other accessories with no extra power supply in addition to USB connectivity. That means fewer cables on your desk and possibly a reduction in costs when manufacturers do not need to send with the power adapter into the wall.
The development team is also working on SuperSpeed USB Inter-Chip, a standardized method to allow integrated circuits to communicate via the USB protocol. The specifications are expected to complete by the end of the second quarter.
