USB-C Guide
Choosing the right USB-C cable: charging, data and video explained simply
Not every USB-C cable can do everything. Some cables only charge, others transfer data, and some support monitors, docks or higher charging power. With this guide, you’ll find the right USB-C cable for your smartphone, tablet, laptop, monitor, docking station and accessories more quickly.
The following factors are always crucial: charging power, data transfer rate, video support and suitability for the specific application.
In a nutshell: Which USB-C cable do I need?
A simple USB-C cable is often sufficient for charging alone. For fast charging of tablets and laptops, the cable should be rated for the required power. For external SSDs, hubs and docking stations, the data rate is crucial. For monitors, you need a USB-C cable that supports video.
Therefore, don’t choose a cable based solely on the connector, but always on the actual intended use.
Overview: How to correctly categorise USB-C cables for charging, data transfer and video output.
USB-C for charging
For smartphones, tablets, laptops and power banks with the appropriate charging power.
USB-C for data
For file transfers, SSDs, adapters, hubs and fast connections.
USB-C for monitors
For displays, docks and video output via compatible USB-C functions.
USB-C for high power
For high-performance power supplies, laptops and professional workstations.
Why USB-C cables are so often confused
USB-C primarily describes the connector shape. This does not automatically determine which functions a cable actually supports. Two cables may look similar on the outside yet have very different capabilities.
One cable only charges, another charges and transfers data, whilst yet another is also suitable for a monitor or dock. This is precisely why the specification is more important than the shape of the connector alone.
Quick selection by use case
Charging only
A simple USB-C charging cable is sufficient if high data rates or video functions are not required.

USB-C for charging: what matters
When charging, the power supply, device and cable work together. A high-performance power supply alone is of little use if the cable is not chosen correctly. A standard cable is often sufficient for smartphones. For tablets, laptops and more powerful power supplies, the supported charging power should be clearly stated.
If you want to charge devices reliably in everyday use, you should pay particular attention to build quality, the right length and the intended use. In a professional environment, standardised equipment and regular use also play a role.
Practical tip: A simple cable is often sufficient for charging smartphones. For laptops and workplace solutions, the choice of cable should be examined more closely.
USB-C for data: Not every connection is equally fast
A common mistake is made when it comes to data transfer. Many cables are sufficient for charging or simple connections, but slow down external SSDs, docking stations or larger file transfers.
Choosing by use
Simple charging and basic data: sufficient for standard applications
Everyday use and accessories: for mice, keyboards, adapters and many standard devices
Faster data connections: for modern peripherals, storage and docks
Demanding setups: for large amounts of data, docking stations and modern workstations
Anyone who regularly transfers photos, videos, backups or project files should choose a cable with clearly stated data performance.
USB-C for monitors and video: what you should look out for
A USB-C connector does not automatically mean that a monitor can be connected via it. For displays, docks and multi-port adapters, both the end device and the cable must support the relevant function.
For monitor workstations, desk setups or meeting rooms, the cable should therefore be explicitly suitable for these applications. A standard charging cable is often not sufficient for this.
Choosing the right USB-C cable in a B2B environment
The same basic questions apply in a business environment: Is the cable intended solely for charging, data transfer, or should it also support video? The difference lies in the fact that businesses often procure cables in standardised form for multiple workstations, docking stations, laptops or monitors.
