Terms to Know Before We Start
Before we dive into the different types of USB cables, let's start by discussing some USB basics.
When discussing USB cables, some common terms are used frequently, such as version and type:
Understanding USB Version
Version is used when describing the specific USB technology that a cable uses. USB cable versions let consumers know the highest speed capable by the cable, along with its maximum length. See the USB version table below for more details.
USB 2.0 vs. USB 3.0 vs. USB 3.1 vs. USB 4
The latest version is USB 4, which is housed within USB-C cables. It offers faster speeds for data transfer and is compatible with older versions.
USB version 3 is easy to spot thanks to the blue accents on the USB plug itself. Any port or cable compatible with USB 3 will feature the same blue components. Note that USB 3.0 is also referred to USB 3.1 Gen 1, and USB 3.1 is now commonly referred to as USB 3.1 Gen 2. The latest USB 3.1 Gen 2 cables offer the highest possible speeds and feature a teal color on supported ports and cables. Keep in mind, however, that USB 3.1 Gen 2 is still quite new and infrequently used, though its adoption is sure to increase over time.
Maximum Speed and Length
| USB Type | Version Supported | Maximum Speeds | Maximum Cable Length |
|---|---|---|---|
| Type-A | 2.0, 3.0 (3.1), 3.1 Gen 2, 4 | 480 Mbps, 5 Gbps, 120 Gbps | 16 feet (2.0), 9 feet (3.0), 2.6 feet (4) |
| Type-B | 2.0, 3.0 (3.1) | 480 Mbps, 5 Gbps | 16 feet 2.0, 9 feet 3.0 |
| Type-C | 2.0, 3.0 (3.1), 3.1 Gen 2 | 480 Mbps, 5 Gbps, 10 Gbps | 16 feet 2.0, 9 feet 3.0 |
| Micro-B | 2.0 | 480 Mbps | 16 feet |
| Mini-A | 2.0 | 480 Mbps | 16 feet |
| Mini-B | 2.0 | 480 Mbps | 16 feet |
| Micro-AB | 2.0, 3.0 (3.1) | 480 Mbps, 5 Gbps | 16 feet 2.0, 9 feet 3.0 |
Understanding USB Type
Type is another word you will often hear in reference to USB cables. Type simply refers to the shape of the cable — think of USB-A or USB-C and their different plugs. Male and female are also frequently used to describe cables. Male means that the cable end plugs into a port, while female refers a port or a cable that can have another cable plugged into it, such as a USB extender.
Most Common USB Cables
Knowing the proper cable for the job can save valuable time and money when setting up an office or workspace — and knowing the cables you don’t need can help reduce clutter or the possibility of user error when employees or family members look for the right cable to use.
Some types of USB cables are more common than others. Check out this table for some of the most common USB cables and their typical uses:
To optimize the technology you're using, it’s essential to understand USB cable versions and types. Nothing is more frustrating than having your new USB 3.1 device functioning at 2.0 speeds just because it's plugged into the wrong port. With this guide, you'll learn the differences to ensure you get the most out of your technology.
USB Cable Types
Cable type is usually the primary identifier when purchasing a USB cable. When searching online, it will often be the first thing you look for. Each type of USB cable has a unique shape that will help to identify it.
Version is also important, but if you have the wrong type of cable, then it won't work at all. If you have the wrong version of the cable, it will still function, just not at optimal speeds.
Let’s look at USB cable types and their most frequent features and uses below:
USB Type-A
Without a doubt, USB-A is the most common USB cable, and it is often the first that comes to mind when you hear "USB." Type-A supports all versions of USB and is found on virtually every piece of modern technology. This rectangular plug is used for many devices (flash drives, for instance) and often is one end of a cable for all other types of USB, such as Micro or USB-C.
For instance, many USB cables will have a USB-A end to connect to a PC or power adapter, and another type on the other end to connect to a specific device. With most phone chargers, for example, the end that plugs into the wall adapter will be a USB Type-A cable.
USB Type-B
USB-B has a smaller, squarer connector and is used most commonly with printers and scanners. With these cables, one end is typically Type-B while the other is Type-A to connect to a computer. Past its prime, USB Type-B cables are finding less use with the introduction of wireless printers and other new technology. USB-B cables, however, still support USB version 3.1, so you can expect to see them for a while longer.
USB Type-C
The new kid on the block, USB-C, can be found on new technology such as cellphones, the Nintendo Switch or Sony PlayStation 5. Capable of incredible speeds, USB-C cables are seeing more frequent use everywhere. Their ability to transfer data and power on a single cable has made USB-C a new standard in the tech industry.
Be careful when purchasing this type of USB cable, as not all USB-C cables are created equal. Some may be strictly for power or data transfer. Be sure to check the specs on your USB-C cables and devices before making any final decisions. This type of cable may also be called Thunderbolt or USB-C PD (for “power delivery”).
Micro USB-B
Micro USB-B cables are probably the most common USB cables besides Type-A. Android phones from years prior and modern gaming consoles use this smaller form factor USB for charging controllers and devices. Its shape looks like a shrunken HDMI cable, and it is the smallest of all USBs.
Mini USB Type-A
Incredibly rare and mostly phased out for the superior Micro USB technology, Mini USB-A cables look very similar to Mini B but have curved edges on the plug rather than jagged ones. These are primarily used in older cameras and typically are a proprietary cable. The Mini A is rarely seen today.
Mini USB Type-B
The predecessor to the Micro USB-B, the fatter Mini USB-B has a larger rhombus shape. While still in use today for some digital cameras, the mini USB has mostly been replaced by the smaller and more efficient Micro B cables.
Micro USB AB or Micro B 3.0
Micro USB-AB female ports have the unique ability to accept either Micro B 2.0 or Micro B 3.0 (3.1) USB cables. The versatility of Micro AB cables makes them a popular choice for external hard drives and devices that can benefit from the added flexibility. A version 3.0 (3.1) Micro-AB cable is also referred to as Micro-B 3.0 (3.1).
Micro USB-AB cables can use USB 3.0 (3.1) technology and are thus a regular choice for moving large blocks of data. The cables will often have the wide USB-AB plug on one end and the USB-A on the other end for connecting to a PC or laptop.
Choosing the Right USB Cable for Your Needs
Now that you know all the different types of USB cables out there, let's go over some of their more specific uses.
For Printers
Most printers still use a USB-B cable. Consequently, connecting a newer laptop to a standard printer will likely require a USB-C to USB-B cable.
For Charging Devices
The European Union has passed legislation adopting USB-C as a universal charging standard for devices sold in the EU. The requirement applies to all small and medium-sized portable devices by the end of 2024 and will extend to larger electronics, including laptops, by the end of 2026.
For Data Transfer
USB-C offers faster data transfer rates than other USB cables and can be used to transfer data between two phones, between a phone and computer, or between a phone and a TV with an HDMI display.
For Gaming and High-Performance Devices
USB-C is the best option for gaming and high-performance devices because it provides the highest rate of data transfer and more power. In addition, it can handle high-resolution video, which is used by many gaming devices.
