This is a genuine HP 18.5/19.5V 3.5/3.33A 65W smart power adapter with a 7.4mm x 5.0mm connector. HP laptops are very particular. Aftermarket adapters can damage the charging circuits on HP laptops. We strongly recommend you only use a genuine HP smart power adapter with your HP devices. The product number or product ID is unique, used to identify your HP devices. The condition is used, but it is good as new, just a lot cheaper.
