I'm having considerable trouble trying to figure out what power adapters I can use with my HP Envy 13, and where to buy them. I would appreciate it if someone could tell me how I should be searching for them, especially regarding what factors are VITAL for an adapter to work properly with my device (i.e. you should only use X-volt adapters or Y-brand adapters) and which factors can vary without risking damage. For example, I got the impression like the wattage is a vital factor as I was browsing online, but then I came across an HP guide discussing how a lower-watt adapter would affect the laptop's performance. For another example, I have no idea whether or not an adapter that's listed as compatible with an HP ENVY 13-aq... laptop would work identically with my 13-ba... model.
I would deeply appreciate some clarity on the matter, trending towards too much information/too in-depth instead of too little information/not in-depth enough.
