    Many people have asked on this forum for 12V to mains inverters.
    Here's a video explaining the shortcomings of this ubiquitous simple circuit (and probably many similar circuits):

    Well, that's what a MOV is for to shunt unwanted voltage, driving sensitive stuff is a no go but... power tools, lights it's better than darkness in an emergency

    I saw this too. Thanks for sharing.
    Good point. Would be good to advertise this circuit as such though... I'm sure a number of people have cooked things not understanding it's limitations.
