What is the output voltage of that module? Can you technical data for the module (data sheet)?

its 5V

I will reserve judgement till I see some documentation.

if u mean the module i have some documentation but its not in english

Is there a schematic diagram? That is more or less universal language.

If it has a voltage regulator then go ahead, however, it appears Mickey Mouse designed it.

actually i guess so , cause its very cheap
