I was curious about the amps being drawn on the ML2 running at 900Mhz and 5.10Mhs and today i received a little USB inline meter. To my surprise the sole unit I have right now says that it is drawing about 4.6v and 2.5 amp - did not expect it to be that high on the amperage.
Link to the meter you're using? I considered getting one but after seeing several reviews saying they smoked the meter with a high amp draw USB device I figured these stick would do the same to them. No doubt these are ragged edge USB power consumption with the speed turned up. I've yet to have success with any hub supporting more than 2 of them at 954mhz.
