Lenovo USI Pen for Chrome OS

The Lenovo USI Pen GX81B10212 is a new graphics tablet accessory built for extended notetaking, writing, fine art and graphic design. It connects via USI protocol to supported Chrome OS devices and delivers 4096 levels of pressure sensitivity for natural stroke control. The gray pen weighs 1.00 lbs and offers 150 days of battery life based on two hours of active daily use.

Who this suits and who should look elsewhere

This pen suits Chrome OS users who need precise pressure-sensitive input for drawing or long-form handwriting. Buyers on Windows, macOS or Linux platforms cannot use the USI protocol and should look elsewhere. Artists requiring tilt recognition or customizable shortcut buttons will not find those features here.

Deciding specification: 4096 pressure levels

The single specification that decides fit is the 4096 levels of pressure sensitivity. If your workflow demands finer granularity than this, the pen will not meet the requirement. If this resolution matches your creative or notetaking needs, the GX81B10212 is the right part.
