Anyone had good run with cheap Laptop adapters from china?

My cheap $15 replacement 65W adapter I got from china died. It’s showing different voltages. + is only 6v, but – is showing 13. Far from the 18.5V it’s meant to put out. I know it’s the adapter as I tried brother’s adapter from his laptop & my laptop turned on. I have been very careful looking after this adapter. Do the cheap ones just ware out fast with excessive use? It’s just an adapter. The ones in local store look pretty much the same & are $90, I’m reluctant to spend that for an old laptop unless I know it would last a few years. The laptop is a Compaq Presario Q61.

What are your thoughts? Thanks.

How do you mean far from 18,5V. I don't know the immediate tolerances, but 13+6=19, only half a volt more.
Dunno if they should start from ground up to 18.5 or any differential of 18.5 is enough. But if it's the latter, why wouldn't it work

I measured the adapter end with red terminal on small inside pin & black terminal on outside which gave 6V, tried reverse way & it was a -13V.
