This is a genuine HP 19.5/18.5V 3.33/3.5A 65W smart power adapter with a 7.4mm 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. Stop lugging your AC adapter back and forth between home and office. Get a second AC adapter for your notebook and keep one in the office and one for home or travel. This AC Adapter is specially designed to meet the power needs of your laptop. It enables you to simultaneously operate your system and charge its battery from electrical power outlets. It comes bundled with a power cord.
