    It used to be that a wall wart psu used to be only made for one particular voltage. However with the advent of SMD and multi-layered PCB we can cram more in to a space (albeit a questionable reasoning as sometimes more space is good for components to breathe and a heatsink to be included(.

    Nearly all USB wall warts are 'meant' to be switchmode, which means with an adapter they should auto adjust to the voltage of that country.

    In terms of what people have been taking about, the voltage should be fixed however the current can change. Most mods have a fixed input current regulator that can only handle so much, so be diligent. Things like the new DNA boards have 2amp zip charging that throttles back as the batteries reach capacity.


    To answer the question a round about way, they have a set of diodes and a small fuse plus capacitors, all of which potentially protect the mod or item from voltage spike etc.

    With things like the pico, it's more a charge out of the mod situation. I certainly wouldn't be charging in it unless it was an emergency. But mods will get warm to the touch when charging internally. They have to dissipate heat made from the dc to dc conversion some how.

    It was the wall wart that got hot not the mod. I charged a pico inboard for over 6 months without a hiccup my old man over 16 months on board with a pico no problems.

    The usb charger is doing dc to dc conversion too. However because of the amperage of the battery and what the mod wants, the usb charger under load gets hotter, faster(I'm assuming it was a samsung or smart phone charger). Ideally you'd use one that isn't a phone one but I do and they do get hot.

    Bawahaha... They got called wall warts because they were unsightly and ugly adapters that stuck out of power points. Unless your wall is a feature wall I'm sure nobody will give oh a hard time.

    To be fair i didnt know what they were till i read 50% of the thread.
    What we called wall warts back in the day were bubbles in the paint and looked like this.

    Not an Australian power point, looks like rising damp under the paint. Very common in the old stone houses in SA, them houses made with pug lol.
