Designed for Lenovo Chromebooks

This active stylus is built for the 300e Yoga Chromebook Gen 4, 500e Chromebook Gen 4 and 500e Yoga Chromebook Gen 4. It uses the USI 2.0 protocol to deliver precise pen input on those specific devices. The black finish matches the chassis aesthetics of the supported models.

Check Chrome OS and model number

Verify that your Chromebook runs Google Chrome OS and matches one of the listed model numbers before ordering. The pen draws 5 V power from the device and relies on the USI 2.0 implementation in those specific SKUs. Other laptops or tablets will not support its active features.

Rapid charge changes daily workflow

A fifteen second charge provides up to ninety percent capacity, so the stylus is ready almost instantly when you need it. The brown-box packaging identifies it as a customer-replaceable unit for easy deployment in managed environments. No additional software or drivers are required beyond the operating system.
