Basic USB Charging Cable Information

By Johny Jacson


First introduced during the late 90's, the USB charging cable is mainly constructed to connect the business computer units to their corresponding printers. With the inclusion of this to the personal computer model in the later years, this type of cable instantly turned into the standard of the industry.

In the long run, this encouraged the faster data transfers and shorter device charging time. In this article, you will learn more about the charging cable and the benefits that you can get from using the multiple ported ones.

Considerations

For starters, while the devices may have at least two USB ports, the manufacturers somehow fail to label the USB charging cable in the appropriate manner. As a result, you may have a device that charges from one device port but not on the other port. It may be a characteristic of the older devices. This is because there seem to be no reason that the standard downstream ports should be used when the high amperage ports are already available.

Similarly, some of the external devices such as optical drives and hard drives will need more power that the standard USB cannot readily provide. This is the primary reason that the manufacturers do typically include the Y cables or an external AC adapter.

Capacity

Although it is faster than the traditional charging cable, the USB charging cable has a rate of data transfer of around 150 kilobytes per second. This may be increased to 2 megabytes per second if you use the cable and the device under the ECP and the EPP modes.

Compared to this, the first version of the charging cable have a rate of data transfer of around 12 megabits per second that you may elevate to 480 megabits per second using the second specification for the cables. The third version of these cables will increase the speed more. Therefore, this will allow the data rates of around five gigabits per second. The bandwidth will improve the speed of the data intensive operations like scanning. It may even be possible for you to utilize video devices and high speed audio units along with the connectors.

Considerations

The USB charging cable can provide you power for signaling. This implies that the peripheral aspects will need their own type of external power supply for the peripheral powering process. The USB system can further improve on this by helping you provide as much as 500 milliamperes to help you power up the peripherals. You may even increase the power by up to 90 milliamperes if you are using the latest cable version.

Each of these conductors is less than an inch in width. Later released versions such as the micro and the mini types have even smaller dimensions. These are especially designed for the new models. Compatibility wise, this charging cable is considered as the standard for most of the available devices today. Some of these devices include the smartphones and the printers.
