Virtually every new laptop, phone, and tablet nowadays features a USB-C port. At first glance, they all look the same: a small, oval connector where you can no longer insert the plug the wrong way around. Handy. But appearances can be deceiving, because significant differences lie behind that single plug. One USB-C port can charge your laptop, send video to a monitor, and transfer files at lightning speed. The other essentially only handles data. In this article, we explain what those differences are and what to look out for when choosing a hub, cable, or docking station.
USB C is a connector, not a standard
This is the most important thing to remember: USB-C only describes the shape of the connector. It is a small, oval plug with up to 24 pins inside. That shape is universal, but what the port can do depends on the technology the manufacturer has put behind it.
Compare it to a power outlet. Every outlet looks the same, but it makes quite a difference whether it is connected to a 16-amp circuit or a 6-amp circuit. With USB-C, it works exactly the same way. The plug always fits, but the capabilities can vary enormously.
Speed: from slow to lightning fast
Not every USB-C port is equally fast. There are different generations, and the difference is significant:
- USB 2.0 — 480 Mbps. Enough for a mouse or keyboard, but slow for files.
- USB 3.1 Gen 1 — 5 Gbps. Fine for most daily tasks.
- USB 3.1 Gen 2 — 10 Gbps. Twice as fast, noticeable with large files or external SSDs.
- USB 3.2 — 20 Gbps. Seriously fast for professional use.
- USB4 and Thunderbolt 3/4 — up to 40 Gbps. The fastest connections you can get.
The tricky part is that you can't see the difference from the outside. A USB-C port with 480 Mbps looks exactly the same as one with 40 Gbps. Only your device's specifications tell you which variant you have.
Not every USB-C port can do the same thing.
In addition to speed, there are other features that may or may not be present. In theory, a USB-C port can do the following:
- Transfer data — from 480 Mbps to 40 Gbps, depending on the standard.
- Charging — up to 100 watts via USB Power Delivery. Enough to charge a laptop.
- Output video — you can connect a monitor via DisplayPort Alt Mode or Thunderbolt.
- Audio forwarding — more and more devices are using USB-C instead of the 3.5mm jack.
However, in practice, far from every USB-C port supports all these functions. Especially on cheaper laptops and Chromebooks, you often see ports that only handle data and charging, but no video. Fortunately, on MacBooks, every USB-C port does support video, via Thunderbolt or DisplayPort Alt Mode.
How do you know what your gate can do?
A few ways to find out:
- Look at the symbols — A lightning bolt next to the gate means Thunderbolt. That is always the fastest and most complete variant.
- Check the specifications — Look up your laptop's model number on the manufacturer's website. Look for terms like Thunderbolt 4, DisplayPort Alt Mode, or USB4.
- Test it — Connect a USB-C to HDMI adapter to a monitor. Do you get a picture? Then your port supports video.
In general, you can assume that business laptops and higher-end models from Apple and other manufacturers have the extensive ports. With budget models, however, you need to be careful.
Where things go wrong in practice
We regularly see people run into problems related to USB-C confusion:
- An external monitor that displays no image, even though the cable fits in just fine.
- An SSD that performs much slower than expected because the port only delivers 5 Gbps.
- A laptop that does not charge via a USB-C hub because Power Delivery is missing.
- A docking station that does not work because Thunderbolt is required but is not present.
In all these cases, the plug is not the problem. It is about what is behind the port. Therefore, it is wise to check beforehand what you need and whether your device supports it.
Choosing the right hub or docking station
Do you want more ports, an extra screen, or faster data transfer? Then you need a hub or docking station. The choice depends on your laptop and your situation.
Do you work with a MacBook? Then you can choose a USB-C hub that fits your model perfectly . The hubs are available in colors that match your MacBook, such as silver , sky blue , or starlight . This way, you keep your setup sleek and functional.
Do you use a Mac Mini and want more storage and ports? Then check out a Mac Mini docking station to expand your setup with SSD storage, HDMI, and extra USB ports.

A fun fact about the sustainability of USB-C
USB-C is not only faster and more versatile than the old USB-A connector, but also more robust. While USB-A can be plugged in and out an average of 1,500 to 2,000 times, USB-C achieves more than 10,000 cycles. This is great if you regularly connect and disconnect cables.
Frequently Asked Questions
Is USB C the same as Thunderbolt?
No. Thunderbolt uses the same USB-C connector, but is a separate protocol with higher speeds (up to 40 Gbps) and more features. Every Thunderbolt port is a USB-C port, but not every USB-C port is Thunderbolt.
Can I charge my laptop via USB-C?
That is possible, but only if the port supports USB Power Delivery and the wattage is high enough. For most laptops, you need at least 60 watts.
Why doesn't my monitor work via USB-C?
Your USB-C port probably does not support video. Check if your port has DisplayPort Alt Mode or Thunderbolt. Without that function, you cannot output video via USB-C.
Does the cable matter?
Absolutely. A cheap USB-C cable often only supports USB 2.0 speeds and no video. Use a cable that matches the capabilities of your port. For Thunderbolt, you need a certified Thunderbolt cable.
Summary
USB-C ports all look the same, but performance varies enormously. The connector is universal, but the technology behind it is not. Always check your device's specifications before buying a hub, cable, or docking station. This will prevent your monitor from showing no image, your SSD from running slowly, or your laptop from failing to charge.
