The Baseus Smooth Writing Wireless Stylus Charging Case is compatible with the Baseus Smooth Writing Stylus, which suggests it should work with similar models like the Smooth Writing 2 series. However, specific compatibility with the Smooth Writing 2 series is not explicitly confirmed in the available information. It is generally designed to support Baseus stylus models, so it might be compatible, but checking with the manufacturer for precise compatibility is recommended.
