The HP USI Rechargeable Stylus is – like you’d expect – a universal pen that can be used on any Chromebook with USI compatibility. While this is true, the HP possesses a few unique attributes, mainly the ability to magnetically attach to many HP Chromebooks in a very solid, stable fashion. While this connection doesn’t charge it, the connection is solid enough for staying put on the move and gives your pen a great place to live.
