    Yes, from your wall, its AC while on your pc/mac, it's USB, much much slower. Usually it's about half of the current of wall output.

    You only get about .5amp (500mA) from a USB port!


    Edit: And that is the high end!
    I would say in general you get about 20% or more charging potential from wall voltage.

    More than that. You get double the amperage charging with the OEM charger (1A). USB is painfully slow charging. I don't use anything less than 700mA.
