Lenovo USI Pen for 300e/500e Chromebook Gen 3

This rechargeable stylus is built exclusively for the Lenovo 300e and 500e Chromebook Gen 3 models. It slots directly into the device for secure storage and automatic charging. The pen targets students and professionals who need precise digital inking on these specific laptops. It is not for owners of other Chromebook generations or non-Lenovo devices.

4096 pressure levels with 40-minute active runtime

The pen delivers 4096 levels of pressure sensitivity for detailed sketching and annotation work. A full charge from the Chromebook slot provides up to 40 minutes of continuous active use. Heavy note-taking sessions may require intermittent docking to maintain power. Users needing all-day untethered drawing will find the runtime limiting.

USI protocol and integrated slot charging

The stylus uses the Universal Stylus Initiative standard supported by the 300e/500e Gen 3 hardware. It charges only when housed in the dedicated Chromebook pen slot. There is no external charging port or replaceable battery. Buyers must verify their exact Chromebook model supports USI and includes the physical pen garage before purchase.

How can I verify the 4096 pressure sensitivity levels are working after I pair the pen?

Open a compatible drawing or annotation app on your Chromebook and test light versus heavy strokes; the line weight should vary smoothly across the full 4096 levels of pressure sensitivity.
