What are the Different Types of USB Ports and Connectors?

Different types of USB (Universal Serial Bus) ports and connectors vary by shape and size depending on the type of device.

Here are some types of USB cables based on USB Speed Standards and devices.

USB 1.0 to 2.0 to 3.0

USB 1.0 to 3.0 are under USB Speed Standards.

USB 1.x is already considered obsolete. It was replaced by USB 2.0 in the year 2001 which has a faster data transfer rate than USB 1.x. USB 1.x can only transfer 1.4 Megabytes per second (Mbps). USB 2.0 can transfer 40 Mbps.

Around 2008, USB 3.0 was launched. However, there are still cheaper USB cables that are under USB 2.0.

USB 3.0 connectors can work in USB 2.0 ports. Most external hard drives and high-end flash drives have USB 3.0 connectors to have the fastest data transfer speeds. It can transfer up to 5.0 Gigabytes per second. USB 3.0 connectors are often marked with a blue coloring or a lightning sign.

USB Type-B

Printers and scanners commonly have USB Type-B ports to in order to connect with computers. USB Type-B ports and connectors have an almost square shape. This is why universal USB cables have a USB Type-A connector in one end and a USB Type-B connector in another.

Mini-USB

Mini-USB ports are common for smaller devices such as smartphones, cameras and MP3 players.

Micro-USB

Micro-USB ports and connectors are made for slimmer devices such as Bluetooth speakers, power banks, cheaper smartphones and cables of charging stands. 

USB-C

This type of port can be found in new devices (especially in mobile devices) as it offers faster data transfer speed than previous USB types. Unlike the other USB types, USB-C can be plugged upside or downside.
