    Slow to charge when plugged in via USB

    When I plug my LG G2X into my netbook via USB, it takes atleast twice as long to charge the phone compared to wall charging. Any way I can make it charge faster from my computer? Thanks.

    Nope no way, usb can only draw so much power.

    If you're on the go and need a quick charge, use an outlet

    I belive this has to do with the ports on your pc. Their isnt anything you can do except just plag in the wall. Maybe a computer out their does have a dedicated usb but i dout it. its voltage would have to be higher then normal i think.
    Turtle bit me.I thought they were slow....they snap so fast. ................. <3

    wall charger = 5v 1 amp
    usb ports = 5v 500 mA (.5amp)

    so since USB puts out approx 1/2 the power it takes longer to charge.

    these numbers will vary but its in that ballpark.
