# Extension cables

### Overview

Sometimes your cables just aren't long enough. In those cases, you can use extension cables.

## USB-C extension cables

### Key requirements

* For pen tablets
  * It needs to support data and a small amount of power. Any USB 2.0 extension cable should work.
* For pen displays
  * It must support data
  * It must support DP alt mode
  * It must support the resolution and refresh rate you need
  * It must support sending enough power to your pen display
  * <mark style="color:red;">**SAFETY CRITICAL**</mark> It must support **at least** as much power as the tablet's original cable. If it is not rated to handle that much power, it can become a safety or fire risk.

### What I use for USB-C extension cables

I have used a 2-foot UseBean USB-C extension cable. It has worked well for me. I have run up to 4K\@6Hz through this extension cable.

I used it in these scenarios:

* With a Huion Kamvas 22 Plus (GS2202): I connect it to the USB-C end of a Huion 3-in-1 cable.
* With a Wacom Cintiq Pro 16 (DTH-167): I connect it to the USB-C cable that came with the Cintiq.

### Recessed ports for USB-C connections

Be aware of how deeply the port is housed in the pen display. The specific USB-C extender above has a plug that fits into some pen displays, but other pen displays have more deeply recessed USB-C ports. This cable will not fit those ports.

For example, The USBean extender I use does NOT go deep enough to fit into a Huion Kamvas 13.
