    Way less than that- I don't know what chip is in that device, but for example, the BCM2045 uses 50-60ma when active, according to the spec.
    The chip I found is not likely to be the one in your device, but the power draw should be similar.

    Okay thanks. None of the sellers of those know anything about their products. I got it free with a USB hub purchase. It seems to work well. Just trying to add up all my power usage.
