I am sure that many of our readers come across situations where they would prefer USB for a little more energy for their device. Your phone or iPod, ever so slowly charging or external drive that works only on "food" USB ports — or should be inserted into the socket. Sockets, in this day and age! I ask you!
Fortunately, the SuperSpeed USB Group (or any shady illuminatus, it really defines the USB) Decides that the next generation USB 3.0 (PDF) will include support for shocking 100 Watts of power. This is enough to keep the 10 disks or LCD or even the entire laptop. And believe it or not, it uses the same cables and ports, which we have already received.
It's really quite a big jump from standard W 5 or 10 Advanced Watts, found in the normal USB ports. Even Thunder vaunted (and electric sounding) only supplies 10W. With 5 GB/s and 100 Watts of power USB specification, you can enter the second spring here. To keep the larger and more complex devices like printers, monitors and speakers can make it even more versatile than it already is. This is a real leg up on the peak of lightning and light structures, which, although they can handle data from ten external drives, most likely could not power more than two of them. Cables must be able to process about 1.5. It is not clear how the power load will change, but Division is reasonable to believe that they will increase the number of concurrent loads.
Currently, despite the fact that the new specification will use the existing cables, there are potential problems. Not all sources of supply and motherboards are prepared for this type of transfer of power and improperly managed, these high power can burn components, tax PSU and cause overheating. Carrying charge USB cables of low quality already melt and catch fire. But it is disingenuous of me to propose this as a weakness, when the authorities closely monitored USB controller and should be used only for power and currents, tested and known safe taking class USB devices. I'm more worried that several devices and computers will have power of overhead to support this, because they rather choose UPF, carefully taking into account the power draw requirements of the system.
Fears of obsolete equipment, the gap in the direction of the flame, I think it's quite interesting. This is a serious growth and may allow a different accessory ecosystems. Don't expect to charge ten times faster device just yet, but once the design is completed at the beginning of 2012 (it will look at the Intel Developer Forum in September as well), you might reasonably expect some very interesting USB-powered.
