Difference Between USB-C and USB-A and Why USB-C is the Future?

Confused about all the different USB cables? You are not alone. It is easy to get lost trying to figure out which plug goes where.

USB-A is the older, rectangular connector you’ve probably used for years. USB-C is newer, smaller, and oval-shaped. The big difference? USB-C is reversible and offers faster data transfer and power delivery1.

Knowing the difference matters.

What are the Physical Differences Between USB-A and USB-C?

Frustrated with always plugging your USB-A cable in the wrong way? Are you seeking a plug that you can just plug and use?

The most obvious difference is the shape. USB-A is larger and rectangular, and it only goes in one way. USB-C2 is smaller, oval-shaped, and reversible – you can plug it in either way up.

This simple change makes a big difference.

Physical Comparison

Feature USB-A USB-C
Shape Rectangular Oval, symmetrical
Reversible? No Yes
Size Larger Smaller
Pins Typically 4-9 24

What are the Performance Differences Between USB-A and USB-C?

Tired of slow file transfers? Want a cable that can charge your laptop and your phone?

USB-C generally supports much faster data transfer speeds3 and higher power delivery than USB-A. This is because USB-C can be used with newer USB standards like USB 3.1, USB 3.2, USB4, and Thunderbolt.

Speed and power matter.

Performance Showdown

Feature USB-A (Typical) USB-C (Typical)
Data Speed Up to 5 Gbps (USB 3.0/3.1 Gen 1) Up to 40 Gbps (USB4, Thunderbolt)
Power Output Up to 4.5W (USB 3.0) Up to 240W (USB PD with EPR)
Video Output? Usually No Yes (DisplayPort Alternate Mode)

Why is USB-C Considered the Future of Connectivity?

Seeing USB-C everywhere and wondering why? Thinking, can this really replace all my other cables?

USB-C is becoming the universal standard because of its versatility, speed, power capabilities, and reversible design. It can handle data, video, and power all in one cable, simplifying connectivity.

One cable to rule them all.
