HP 90W Power Adapter for HP Laptops

How to know for sure if this will work with a given HP laptop?
For example, HP Notebook 15-ay091ms . . .

For use with a wide range of models?eg?

Unfortunately, HP doesn’t give information on that. On Amazon, someone said it would work with most recent hp laptops. Sorry.

Yes, there is no information about this product on any HP website. Makes me wonder if it is an authentic HP product. If it is, why have they erased all mention of it and why do they not say what laptops specifically it is or is not compatible with? Does Woot accept returns in cases of incompatibility?
