How to Identify Different Types Of USB Cables: A Brief Guide

Modern variations of USB are not just limited to communication only as they now focus on power delivery too. However, it gets a little trickier when choosing the right type because USB has evolved into many variants today. Smartphones, laptops, chargers, power banks, printers, or any device else may all feature USB connectivity of some sort.

So, USB C, Type A and USB B, how are they different from each other? What makes USB so special? We’ll answer these questions through this detailed post while talking about different types of USB cables.

What Are the Different Types of USB Cables?

USB (Universal Serial Bus) cables differ in their plug types and USB standards. Though USB plugs and their version can be different, almost every USB cable serves the common purpose of data communication.

However, newer USB generations are unbelievably faster than their previous generations. For example, the latest USB4 version is 10,000 times faster than USB 1.0. Read further on to see the different types of USB cables and their versions.

Identifying By USB Types

Below is the list of the most commonly used types of USB cables with plug specifications.

USB Type-A

One end of most USB cables is a type-A connector. This is a very common type of USB connector that you can see on computers, printers, chargers, etc. Typically, it has a black rectangle connector that is most commonly used for data transfer up to the standards of USB 2.0 specification. However, the connector can be blue and red for USB 3.0 and USB 3.2 standards. One end of every USB cable is a type-A connector that is used to connect an IT peripheral to a PC.


Micro-B is a tiny 5-pin connector that is most common with small electronics like older smartphones, power banks, and game controllers. The micro-B connector is used for making a data connection between a PC and these small digital devices. It is also used to deliver power to the smartphone’s battery with a charger. The micro-B USB is still common in budget android smartphones that do not have a USB-C receptacle.


The lightning connector is developed and owned by Apple inc. It acts both as a power connector and a data transfer cable. It is most commonly used with Apple’s iPhone, iPad, and iPad. The lightning connector is a proprietary technology so it is exclusive to Apple devices only. The main identification feature of this connector is its unique design. It features 8 pins on both sides which enables you to use it reversibly.

USB Type-C

You must know what is a USB-C port as this is the most common connector today. USB-C charging is the most recent standard of USB technology. It is widely found in smartphones, modern laptops, tablets, power banks, etc. USB-C features a 24-pin reversible plug which means that you can plug it either up or down. Besides, USB-C offers data transfer speeds up to 20Gbps.

Things To Know When Buying USB Cable

Before buying a USB cable, you should be aware of the following things.

  1. USB Type: Before buying a cable for yourself, decide what type and version of USB you want to buy. Cables can have different types of USB connectors as we talk above.

  1.  Manufacturer: Always buy USB cables from reliable manufacturers only because they use high-quality materials to manufacture a cable.

  1.  Certification: Before buying a USB cable check for its safety certifications. These certifications ensure that the cable is safe to use under normal conditions without the risk of fire, short-circuit, and electric shock. These safety certifications are issued to manufacturers by the government.

  1.  Build Type: Rubber USB cables are common, but they get some environmental wear and tear over time. You can also buy braided USB cables because they are sturdier and more resistant to kinks and twists.


We hope that you won’t be having any further doubts about the types of USB cables after reading this definitive article.
