This is the original power adapter that was used with an HP Pavilion 15-e103TU. It is labeled as 19.5V, 3.33A, and 65W. The plug size is approximately 4.5mm outer diameter and 3mm inner diameter. I found compatible products online, which listed the following as compatible models: Pavilion 10 TouchSmart Notebook PC 10-e020au, Pavilion 15-e000, Pavilion 15-e100, Pavilion 15-e101TU, Pavilion 15-e102TU, and Pavilion 15-e103TU. However, this information is not guaranteed, so please confirm compatibility yourself. Thank you. By the way, I may have other parts for this model available, so please feel free to inquire.
