Must-Have for MacBook/Laptops: Complete Guide to Connecting Displays, Audio, and Storage with a USB-C Hub

In modern work and study environments, limited ports on laptops have become a common challenge. Whether you need to connect an external monitor, audio devices, or read/write SD cards and USB drives, the built-in laptop ports are often insufficient. This is where a versatile USB-C Hub comes in. In this guide, we’ll take the LENTION 8 in 1 3.3FT USB-C Hub (CB-C37-1M) as an example and show you a complete tutorial on connecting multiple devices efficiently.

1. Why Choose a USB-C Hub?

Modern MacBooks and high-end laptops mostly use USB-C ports. While fast, the number of ports is limited. A USB-C Hub can expand a single port into multiple functional ports, solving these problems:

• Connect to an HDMI monitor or projector with 4K resolution

• Use headphones, microphones, or speakers simultaneously

• Read/write SD cards and Micro SD cards for fast data transfer

• Provide USB 3.0 high-speed ports for USB drives or external hard drives

• Support USB-C Power Delivery (PD) for simultaneous charging and data transfer

The LENTION 8 in 1 USB-C Hub not only provides multiple ports but also comes with a 3.3FT long cable, making desktop setup more flexible.
