Anyone who uses any type of mobile device these days is familiar with at least one of the various types of cables necessary for charging these devices. Of course, all of these various types of cables belong to the USB family, a portable technology that has only been around for roughly the past two decades. And since arriving on the scene, this very new and remarkable technology has already evolved immensely, growing to meet the escalating needs of the average consumer.
To understand where we have come from and where we are going we should probably first define what USB is, actually. USB stands for Universal Serial Bus, and it was named such in the mid-1990s. USB technology was originally designed as a way to standardize data transfer protocols from the many machines in use within the technology sector. As such, USB was specifically intended for data transfer (and not, for example, battery charging or peripheral device support).
Roughly ten years later, USB 2.0 evolved. This, of course, was the second iteration of the USB protocols, which evolved some the USB design and functionality. As mobile technology was a quickly emerging and growing field, the USB standard became a model for what would also become standard within the industry. Among this evolution, USB became a means for charging devices, and the present standard—USB 3.0—is the fastest and most reliable iteration to date.
USB 3.0 protocol is not just faster, though, it is also more efficient in terms of size. The port and input, for example, are smaller than the original USB protocol port and input.
The most emergent standard in USB protocols is known as USB type-C. This is now the base standard for both traditional data transfer and for battery charging in the mobile technology industry. This is a 24-pin USB connector that provides excellent support for high speed data transfer—at 10 gigabits per second—and battery charging—up to a 100 watt output. Also, it is the first to be reversible. For a while, only Apple devices used this USB type C adapter from primecables.ca technology, which probably puts Apple slightly ahead of the rest of the field in this regard. Of course, there are also various adapters that let you connect older devices to USB type-C cables and devices.
