    Hello!

    If I post here pictures of the inside of those generic cheap chargers, you can tell by looking at the pictures if it's a safe charger with all the safety "stuff" needed? for example surge protection or stuff like that? Because I heard that cheap chargers can damage your device, or yourself? :confused:
    I can post a genuine galaxy s3 entrails picture if you want to compare as well :D

    Good day!

    If you post the pictures, you may or may not get a response.
    If you can post the schematic, there are chances of a discussion, opinions.
    The decision is still yours, but with more inputs.

    I don't think it is appropriate for this forum to make a remote judgement of the safety of a device that can cause injury or death.

    I guess you are right :D
    but assuming this genuine galaxy s3 charger is safe, you can tell what everything does? I mean as an expert?

    I see two high voltage capacitors (C1 and C2), inductor (L1), perhaps a fuse (F1), two low voltage capacitors (C21 and C22), a transformer (T1) and a USB connector. The voltage regulator could be on the other side of the PCB. There is an unidentifed component (possibly a transistor Q1) covered with white goo.

    If you are concerned then stay away from a cheap generic charger.
