Soon, not just smartphones and gadgets whose batteries can be charged via USB cable.
A new USB 3.0 standard is being prepared reportedly will increase the amount of power that can be streamed through this data cable. Magnitude up to 100 watts, enough to charge large devices such as notebooks.
This was stated in the announcement USB 3.0 Promoter Group consisting of a Hewlett-Packard, Intel, Microsoft, Renesas, ST-Ericsson, and Texas Instruments, dated July 18, 2012.
The number is far greater than the maximum power that can be transmitted via USB 3.0 cable that already exist, which is 4.5 Watt. The USB 2.0 cable is only capable of supplying power hinga 2.5 Watt. About the data transfer, USB 3.0 has a speed of 5 Gbps.
The new USB 3.0 standard cable will offer six different profiles based on the amount of power can be channeled. Magnitude from 12V to 5V/2A or 20V/5A (100 Watt).
USB 3.0 cable will be used to replace the laptop charger function. However, seen from the history of USB 3.0 which first introduced in 2008 and just beginning to be applied as a standard feature a few years later, it looks like the emergence of this new cable will still be delayed for some time.
