Fast Charging USB Type C Cable For Smart Phones

USB or Universal Serial Bus has been the common household name ever since it came into being, a little over two decades ago. It replaced the need to carry separate power chargers for computers and other peripheral devices such as keyboards, printers, digital cameras, phones and so on. USBs established the standard for communication, connectivity as well as power supply between a host device like a personal computer and all the peripheral devices connected to it. They replaced all the parallel and serial port connections between devices, bringing all such device-device communication protocol under a standardized umbrella of USB products, depending on the USB type. The shape of the ports/connectors, the speed of data transfer, the size of the cable – all these became standardized with the intervention of USB.

Now, as with everything about technology, the myriads of options available in todays market for the USB accessories are certainly mind boggling. Manufactures came out with USB 3.0 and USB 3.1 and then you hear about USB Type A and Type B. Added to these there are mini USB, Micro USB and so on.

There are also leaps and bounds of progress in speed of data transfers using USB – 40 Gbps and power of 100w enough to charge a host device like a laptop and even flexibility of splitting a single cable in to a hub to accommodate more USB devices, using a single cable.

What do the USB 2.0, 3.0 and 3.1 mean and what is USB type A B or C?

The fundamental difference is one refers to speed of cable and the other refers to the port/connector type – the size and shape. In other words USB 2.0, 3.0 and 3.1 refer to the standard with respect to cable speed and function while the USB type A, type B and Type C refer to the shape of the cable connector and the shape of the port on your electronic device like computer, camera etc.

For example USB type A or USB A is the large port you would find on your computer and Type B is found on printer like devices. The micro B and Mini type B ports are found on devices such as cameras etc. The combination of the two determines the speed of cable and what kind of devices it connects to.

USB type C has been creating the biggest splash – the latest and the greatest so far in the world of USBs. It is reversible which means you don’t have to worry about which side of the cable is up when you insert it in the device. The symmetrical nature of the cable plug accounts for its reversibility. Most of us have faced the frustration when we have inserted the USB cable upside down in a device. The type C resolves this issue.

Because of its flat nature and the cable plug being just slightly larger than a micro USB, it supports smaller devices – so smaller and flatter our electronic devices get by the day, the more the type C USBs will be used. Also if you have a host device like a PC and a peripheral device that both have USB – C ports you can swap and plug either end of the cable plug into the peripheral device and the other into the host device.


The USB type C is also great for charging devices – bidirectional power means one can charge not only a peripheral device from a host device but a peripheral device could charge a host device too, when host device goes low on power. When the USB type C is coupled with USB power delivery it can be used for charging big devices.
