Maybe you’ve ever packed the wrong charging cable for a weekend getaway. You might already be aware that there are more than just two types of USB cables. But you may wonder why exactly these types exist in the first place? After all, isn’t the goal to create a connection? And if so, why does it matter what USB cable is used? Certain designs are limited to mobile devices, while others are used to build stronger connections with computers and peripherals.
The advent of USB greatly simplified making connections. Instead of a jungle of wires, we untangled the requirement to a minimum. And as technology grew more complex, we found more accessible ways to transfer data. Essentially, USB created an industry-standard that set the rules for cables and connectors. With each new USB cable introduced, speed, performance, and power delivery improved drastically. So it’s safe to say that the various types of USB cables don’t exist to make your life complicated. In fact, you’re introduced to a world of more efficient data transfer with each new type.
To help you understand more about these types, let’s take a deep dive into the world of USB cables:

The journey of the USB cables used to charge phones and tablets today started with the mini USB. It was introduced in the early 2000s. It was mainly to allow data transfer from a digital camera, mp3 player, or even some of the older phones. While the technology may not be a driving force today, it pretty much shaped the landscape of the USB cables currently in action.
Apart from starting a new chapter in technology, it proved incredibly convenient due to its size. The mini USB is much smaller than the traditional USB type A or B. Therefore, carrying it along was no longer a hassle. Instead, you could put it in your back pocket. Thus, making it ideal for charging phones. Additionally, it’s a five-pin version of the traditional four-pin USB cable. The extra pin acts as an ID pin, allowing the host device to be differentiated from the other devices.
Similar to the traditional USB, mini USB offers two cables – mini A and mini B. There is no drastic difference between the two. It’s just a matter of device compatibility. Mini B works better for mobile devices, whereas Mini A is used for printers. Since most phones and cameras have upgraded to the latest USB cable, mini USB is a sight for sore eyes. But a mini USB would work tremendously if you still somehow have an older Blackberry or Motorola.

Within two years of introducing the mini USB, it became clear that the world was ready for an improved version. Unfortunately, the micro USB didn’t come with a drastic size reduction. In fact, both mini and micro USBs look pretty similar to the naked eye. And they both support a five-pin design. However, there’s a difference in the shape of the cable. Where the mini USB is a trapezoid-like shape, the micro USB is rounded at the top. So why exactly did the need for a newer USB arise?
As it turns out, the difference between a micro and mini USB is significant. But the advancement lies in the functionality and performance rather than the shape or design. The micro USB offers almost double the cycle life of a mini USB. As for the data transfer speed, micro USB can provide a minimum speed of 480 Mbps to a maximum of 5G bps. In comparison, the same rate is incomprehensible for a mini USB.
As the leading USB contender in the global market, micro USB has largely replaced mini USB. From android mobile devices to digital cameras, micro USB is used. Another feature that has allowed micro USB to dominate the market is the USB OTG feature. The ‘On The Go’ or OTG feature enables mobile devices to act as hosts for peripheral devices. In simple words, you can connect your phone or tablet with a mouse or keyboard using a micro USB. Better yet, you can connect your game controller to your smartphone and play your favorite game in a new way.
Faster data transfer, efficient charging, and the OTG feature are some of the highlights of a micro USB that allowed it to become a dominant force.
- Charging and powering smaller devices
- Transferring data between them
Just as the invention of the mini USB introduced a new wave of technology, USB-C is destined for the same fate. In fact, it’s believed that USB-C is very much the future of USB technology. It has the potential to be the ultimate design as it can be used on a plethora of devices. However, it’s still in its early phases. Currently, only certain laptops, smartphones, portable chargers, and even security cameras use USB type C.
When it comes to the design, USB-C has a symmetrical oval shape. So if you’ve ever struggled with plugging the USB on the first try, this is existing news. Apart from the accessibility, the performance and speed of USB-C also remain unmatched. With the right cable-to-port combination, USB-C can transfer data up to 10 Gbps. Additionally, charging cables using the type C design is much faster at juicing up your device. It can provide 100 watts of charging power, which means you can fully charge your smartphone within minutes.
In addition to the reversible connector, USB-C is a 24-pin design. That’s 19 more pins than mini or micro USB! The additional pins allow the cable to transfer data and charge devices at an astonishing rate. With all these advantages, companies have started recognizing the potential type C has. And as more companies opt for type C ports for their laptops, mobiles, and printers, we see micro USB become a thing of the past.

We don’t blame you if you’ve never heard of USB type B. After all, it was invented in 1996. Apart from being amongst the first USB designs, it is only used for larger devices. Such as printers, fax machines, scanners, or even certain internal storage devices. Unlike the other types, it doesn’t function as a charging cable. Instead, it’s primarily used to build a connection between a computer and the peripheral device. It’s mainly used with a standard type A, which goes into the computer. The shape of the cable is rather complex. With a square in the middle that fits into the port, it’s enclosed in a trapezoid shape casing. The USB-B has a four-pin design, similar to the standard USB designs. It also offers other versions which increase the compatibility with the relevant peripheral device.
The design that started it all! Type-A USB brought along a new age of data transmission. It was introduced in 1996, but it remains just as relevant today. The rectangular shape you associate with a USB is the USB-A shape. The standard A has four pins, and you probably have more than a couple lying around in your house. The design appears symmetrical. But if you’ve ever struggled to connect it into a port, you would know it’s actually asymmetrical.
Even if all the other types eventually go out of fashion, type A is here to stay. It is typically used on the host end of a USB cable. The design of USB-A allows for repeated reattachments without an increased risk of damage. It can withstand detachment for a much higher number of turns than its other counterparts. The USB-A can carry both power and data. Therefore, it’s used for the host end of both charging and data cables. Since USB-A is used in combination with almost all the other USB types, you may wonder if there’s such a thing as an A-A combination. You may find it surprising, but an A-A combination is a practical way of connecting two computer systems with a hub. Essentially, it helps create a network with more than two devices.
As we enter the new age of technology, we leave behind certain designs and adopt new ones. Amongst these newcomers is the thunderbolt USB. Just as its name suggests, it’s celebrated for its record high bandwidth speed. Similar in design and function to the USB-C, the thunderbolt is the future of USB technology.
Intel released the first version of the thunderbolt in 2011 and offered a remarkable bandwidth speed of up to 10 Gbps. Let’s consider a practical example to help you better understand how fast 10 Gbps is. If you were to transfer a 4K video, you could do it in less than a minute using a thunderbolt cable. Such a speed was revolutionary at the time of its release since no other cable was even close to achieving this. The first two versions of the thunderbolt have a twenty-pin design.
In contrast, the most recent versions have twenty-four pins. But a mere increase in the number of pins is not all that the new versions offer. Thunderbolt 3 offers astonishing speeds of up to 40 Gbps, which in comparison to the USB-C is about 30 Gbps more. It also allows more connections to be made. Such as, it can connect to two 4K displays or one 5k display at a time. In contrast, the USB-C can only connect to one 4K display at any time.
The benefits of the thunderbolt are crystal clear. In addition to multiple other advantages, it offers greater flexibility and higher bandwidth. But there’s a reason it remains relatively unheard of. Currently, the thunderbolt technology is only adopted by Apple for its Mac computers. More companies have been producing Thunderbolt-compatible devices in recent years due to their undeniable benefits.

USB 2.0 vs 3.0
So far, we’ve only looked at the different types of designs in USB technology. But there’s more to its development. The introduction of the USB standard in 1996 paved the way for betterment. The requirement for data transmission over the years has demanded an improvement in the technology itself. Therefore, different generations form part of this standard. We decided it was time to upgrade the features that make the USB technology distinct every few years. From USB 1.0 to USB 2.0 and USB 3.0, the journey has only gotten more efficient and speedy.
USB 2.0 was introduced in 2000 and remains today’s most common USB standard. The transfer speed offered by 2.0 reaches a maximum of 480 Mbps. In contrast, USB 3.0 was introduced in late 2008 and offered a data transfer rate of up to 5 Gbps. That’s an astonishing ten times more than its predecessor!
So is speed the only factor that sets them apart? Let’s take a look at a few other significant differences between the two generations:
Since the design of the USB cable head depends on its type, differentiating between the generations was a tricky task. However, a clever solution was reached by coloring the heads slightly differently. The USB 2.0 is either colored black or white from the inside. Whereas the USB 3.0 is colored blue. If that’s not enough, you can also set them apart by their connector wires. Where the 2.0 has four connector wires, the 3.0 has a total of nine connector wires.
- Power delivery
Typically, development comes at a high cost. Since the speed offered by USB 3.0 is remarkably higher, you’re likely to find it at a higher price than the USB 2.0. However, it’s an investment that you’ll be glad you got on board with. A few dollars more, and you can transfer data at speed ten times the standard.
You may have purchased a USB cable without identifying the port. The good news is that if you’ve got a USB 3.0 port, your USB 2.0 cable will work perfectly. However, there may be an issue if you have a USB 2.0 port and a USB 3.0 cable. The connection would still be secure, but the port will not translate the high speed offered by the cable. Hence, you’ll be stuck with the standard rate of 2.0.
The USB 2.0 can power up to 500mA. In contrast, the USB 3.0 can power up to a much higher 900mA. Therefore, the power delivery and management of USB 3.0 is exceptionally better. So if you’re looking to conserve energy and get the most out of power supplied, go for the latest generation.
USB 3.0 vs 3.1
The thirst for betterment has encouraged man to go above and beyond. In 2008, USB 3.0 was introduced to transfer data to a speed of 5Gbps. Later in 2013, the USB 3.1 came out with a transfer speed of up to 10 Gbps. The drastic improvement in power delivery and speed allowed more significant applications. For example, USB 3.1 technology is used to juice high-power chargers and battery packs. The USB 3.1 is compatible with USB 3.0 and 2.0 ports. However, the same rule can’t be applied with a USB-B 3.0 cable and a USB-B 2.0 port.
A USB 2.0 cable or device is perfectly compatible with a USB 3.0 port. However, the data transfer speed is limited to that offered by the cable. So with a USB 2.0 cable, you can only reach a maximum of 480 Mbps.
There are several notable differences between the two generations, such as speed and power management. For example, the USB 3.0 offers ten times more than the data transfer speed of the USB 2.0. Additionally, there are visible physical differences that help set both generations apart.
The easiest way to differentiate a USB 3.0 port from the others is by looking at the color of the port. If it’s colored blue, it’s most likely a 3.0 version.
However, not all USB 3.0 versions are colored blue. Therefore, you can look for a logo or any physical label that suggests the generation. As a last resort, you can always check ‘USB controllers’ under your computer’s ‘Device Manager’ window.
