    Sounds like the iPhone charger, does your charger have a removable "duck head"?

    The more power is drawn by the charging electronics, the hotter the charger gets. It _might_ be that the batteries draw more power when they are empty, or (worse) broken.

    If you completely drain the battery (theoretically), the internal resistance is near zero when you start charging, meaning a lot of power flows to the device.

    In short: I would only worry if it gets really hot when you start charging at 50% battery left.

    as the others have said, i'd say it is normal too, I just make sure the actual charger isn't covered by anything and is free to have room air sit around it. Mine sits on the carpet by my bed most of the time.
