# Extension cables ### Overview Sometimes your cable's just aren't long enough. However, you can purchase extension cables. Key requirements for an extension cable * For pen tablets * It needs to support data and 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 * **SAFETY CRITICAL** 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 will be a safety / fire risk. To better understand the needs of connecting a pen display see: [Connecting a pen display](/drawtab/guides/connecting/connecting-pen-display.md). ## The extension cable I use for pen displays I use a 2 foot UseBean USB-C Extension cable. This product has worked well for me. I have run up to 4K\@60Hz using this extension cable. I used it in these ways: * With a Huion Kamvas 22 Plus: I connect it to the USB-C end of a Huion 3-in-1 cable. * With Wacom Cintiq Pro 16 (DTH-167): I connect it to the the USB-C cable that came with the Cintiq. ### ![](/files/Ahnbnt5VUJsHbTLSl3Ve) ## Be aware of how deeply the port is housed in the pen display The specific USB-C extender above has a USB-port that fits into some pen displays, but some other pen displays have their USB-C port deeper inside and this cable cannot fit into those areas. For example, this extender does NOT go deep enough to fit into a Huion Kamvas 13. ### Links * Teoh on Tech: Using Extension Cables with Pen Displays or Graphics Tablets * --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
