Choosing the right USB cable for your computer and accessories.

With each new release, USB ports and connectors become more functional, paving the way for smaller, lighter, and more portable devices. However, as new standards bring more speed, power, and flexibility to the market, they also offer a complex set of features and capabilities that you should consider when deciding which cables or peripherals are right for your application or gadgets. ijsim.com has explained the types of USB ports.

What is a USB?

USB, short for Universal Serial Bus, is a common type of computer connector that makes it easy to charge devices or transfer data between two devices. Since its initial development in the 1990s, USB has evolved along with technology, gradually becoming smaller, faster, and more powerful. With so many devices using USB, it’s easy to get confused by the different ports.

USB evolved through a set of standards that define how cables connect, communicate, with powerful computers, mobile devices, and peripherals. The latest iteration is USB4 and, like previous versions, is another leap forward in terms of data transfer speed, video resolution, and performance.

Types of USB Ports and Connectors.

You’ll usually find at least one of these different types of USB ports on computers, tablets, and peripherals. In newer devices, USB-C is favored for its small size, fast data transfer rates, and ability to transfer power up to 240W. The USB-C cable can also carry 4K and 8K high-definition video. Lightning which is used for iPhone has a similar function to USB-C but uses a different connector.

Many types of USB have emerged over the years, each with a unique design and use case. The most common types are USB-A, Micro-USB, and USB-C, but we’ll cover each of them briefly.


The original flat and rectangular plug, known as USB-A or USB Type-A, is one that nobody can plug in properly for the first time. This cable, which can be used to charge devices and transfer data, is always USB-A on one end and another type of connector on the other. In gadgets like PCs, game consoles, televisions, and a variety of devices, USB-A is still widely used.

USB Type B

USB-B is almost exclusively used in large devices such as scanners or printers. Visually, this connector looks almost square. Most are USB-B to USB-A cables, although some newer devices have moved from USB-B to smaller options like micro-USB or mini-USB. The main reason for the development of the USB-B connector was to allow peripheral connections without the risk of connecting two host computers at the same time. The USB Type B connector is still used today, although it is slowly being phased out in favor of a more precise type of USB connector.

USB Mini B

The mini-B USB port is used in USB gadgets and is similar to the USB-B plug except that it has a smaller form factor. The typical mini-B connector contains 5 pins, including an extra ID pin for USB On-The-Go (OTG), which enables devices like mobile phones to function as USB hosts.

The mini-USB connector was created for previous smartphone models, but as smartphones got smaller and had a narrower profile, it was replaced by the micro-USB connector. Some digital cameras now use the Mini-B connector, and older Mini connectors are no longer used with new devices.

USB Micro B

Some time ago, Micro-USB was the standard for certain portable devices like Android tablets and smartphones because of its ability to transfer data and charge. It comes in Type-A Micro and Type-B Micro variants and is smaller than USB-A. Some manufacturers still choose Micro-USB parts for their devices because they are cheaper than USB-C parts.

USB Type C

Designed to support more compact, lighter, and thinner devices. The sole connector available for video, networking, data transfer, and charging on many modern laptops is USB-C. This combines the transfer of power and data with display connectivity and is the current standard. The majority of modern gadgets, including smartphones, game controllers, headphones, microphones, and laptops, use USB-C. It can be plugged in either way because of the device’s compact, extended, and reversible form factor (get that, USB-A). Even with larger devices, quick charging and data transfer are possible thanks to the 100-watt port connection.

How to Check if Your USB Cable Is Safe

As a general rule, you should always use the supplied cable and also purchase replacement parts from the manufacturer. This cable is specially designed to work with your phone, tablet, or computer. However, if you want to buy it from a third party, make sure to stick with a reliable and established brand. Otherwise, you may end up with an inferior cable.
