“it is doubtful that he adopted it because of Charlie Chaplin. One simple reason that Charlie Chaplin is probably not the inspiration for Hitler’s mustache is that self-consciously adopting the mustache of a silent film comedian would have invited people to ridicule Hitler, which would have stopped his rise to power in its tracks.
“Instead, most of the evidence suggests that Hitler adopted his mustache for more utilitarian reasons either because it was easier to keep hygienic than other German mustache style, because he was forced to cut his old mustache while he was in the military, or because he simply wanted a trademark that would help him stand out as the leader he envisioned himself to be.

Yes, he wanted to stand out from the other politicians and as he was not an impressive build, used the mustache.
