# Upgrading to Wacom One Pen (CP-913)

## Overview

Devices that work with the Samsung S Pen also work with other UD EMR pens. In particular, these devices also work with the Wacom CP-913 pen.

If you are currently using an S Pen with your device, consider buying a Wacom CP-913 to use with it.

* At the very least, you will have a backup pen.
* Max pressure — The CP-913 pen has a higher maximum pressure than the S Pen.
* IAF — The CP-913 has a similar IAF to the Samsung S Pen, and it may be slightly lower in the models I have tested. Keep in mind that individual units vary.

## Which devices benefit

IAF - any device will see an improvement.

Max pressure - any device will see an improvement.

## Samsung Galaxy Tab S with the CP-913

Many Samsung Galaxy Tab users switch to the CP-913 because of its better pressure handling. It is worth trying if that matters to you.

## Key advantages of the CP-913 over the Samsung S Pen

* CP-913 units have a lower IAF, so less force is required for the pen to start drawing.
* CP-913 units have a higher maximum physical pressure. This makes it easier to control how pressure works with your strokes.

## Key differences between the CP-913 and the Samsung S Pen

* The S Pen has a rubber nib.
* The CP-913 uses a plastic nib. It may feel a little more slippery on the glass of a Samsung Tab S device.

## 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.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.sevenpens.com/drawtab/catalog/pens/samsung-s-pen/upgrading-to-wacom-cp913.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
