I made the mistake of leaving my original HP Pavilion x360 Convertible AC adapter at a hotel when traveling. It's been ages since I've had to replace the AC adapter, but I was scared of finding a replacement and wish I'd gone with a laptop that charges via USB-C PD. Not that I thought finding a replacement would be difficult. I just thought it would be expensive. I was very surprised to find several reasonably priced options including this item. There is a proper certification mark on the power supply, but I don't see any serial numbers. Regardless, I used the AC adapter and it works as expected. The wall cable is detachable, but the tight fit is good (usually a potential issue with this arrangement). The device hardly heats up under load. The only thing I would change would be to add an LED to the brick (to indicate power). highlighted.
