Back in 1995 when USB got introduced, it had one main function; to carry data reliably and as quickly as possible.It was a huge success. However, it soon became quite cumbersome for many devices to still have a power cable and then an additional cable to carry data flow.
Eventually, the standard USB cable got replaced by yet another variant in 2000 called USB 2.0. This version featured phantom power, which allowed the data cable to also supply 2.5W of power to and from a device.
7.5W was the standard with USB 3.0, which was released in 2008, however, the data transfer rate of USB 3.0 was 4,800 megabits per second – a whole 4,320 megabits per second faster than USB 2.0.
Then, recently, USB-C became the standard across the board, with its impressive 10Gbps data transfer rate. More impressive was the 20W of power it was capable of delivering.
However, USB-C is getting a huge power increase in the second half of 2021, which will see the new spec USB-C capable of delivering 240W!
