I posted an answer here, and somebody down-voted it but won't defend his action.
He gave one reason which I replied to, but he won't defend it from there.
In this question here
How can I guess if a USB cable will power my devices?
Thoughts?

All you can do is defend your answer to the community in the comments, which I think you did.
Beyond that, downvotes are anonymous for a reason, so it's not possible to require an explanation, though as I said -- defending your answer in the comments is great.
(I thought it was a perfectly valid answer, with good followup comments FWIW, and you have my +1 for your troubles.)
Users are under no obligation to provide reasons for downvoting, or to justify why they did. I understand there is a bigger group of the community that believes you should justify it, however voting is anonymous, and if I have the ability to downvote, I should be able to vote as I wish, without having to justify my reasons to anyone, or even, have to be called out and asked why.
Drive-by downvotes from time to time for example, [...] I know, the system allows it.
- serial drive-by downvotes will trigger fraud checks and most likely will be revoked
There is absolutely no way to tell if the person who downvoted your answer is the same as the person who commented (unless they explicitly say they downvoted in the comments) and @Brad made no such statement.
Also it is well understood that there is no requirement to justify downvotes, although it is nice and appreciated.
