    Wait... DC wall plug?

    Why would a standard plug type be mismatched with a nonstandard power output?

    All my rage...

    @irene Doesn't matter. Because of the rectifier.

    @irene Yes. But not completely.

    @jespersh Yeah. This is in an Indian train.

    @irene if the first thing on the charger is a full bridge rectifier, it will work just fine

    It's weird to see something that looks ancient mention mobile phone charging

    @irene you will be using only two of the diodes on the rectifier and the output of the rectifier will be smooth DC instead of rectified AC (which the device would need to filter so it's smooth anyway)

    Apparently it works if there are wall sockets like this

    @irene it works if the device converts the mains voltage to "high" voltage DC. If it had a transformer to drop the mains AC to smaller AC, it would probably melt the transformer windings.

    With a circuit like this it would only work if you plugged it in the right way but would not break either way. (it has a half bridge rectifier) https://circuitsdiy.com/mobile-char...

    I completely missed the DC 120 part and thought that, because of the weird cutouts it can accommodate both US (flat) and EU (round) plugs.
    Btw that must spark like hell .. dc .. or am i wrong?

    The rectifier will behave predictively, but I am actually unsure how an AC coil/relay will behave with a DC voltage.
    Edit: when the rectifier is after the transformer

    looks like a weird mixture of EU and UK sockets, but with American voltage and DC current 🧐

    @Floydian Mumbai to Hyderabad. 🙃

    @Floydian 😂. Yeah man. In a week.

    @Floydian 😅 Hey I was @notroot. We've already spoken. We planned a meeting but it never happened. A lot of people in the end.

    (Just pinged you on Skype)
