About 260 - 300 mA for R820T/2 models.

It depents if the SDR program is running. Only plug-in consumes +/- 90mA.
I did power consuption messures on all SDR dongles, and the lowest consumption was on the Mini Digivox Deluxe with the old FC0013 chip, and has 170mA.
But not the best dongle in sensivity. The E4000 dongles have a 170mA current consumption.
The R820T dongles have about 300mA current consumtion.
To have the most current comsuption: the SDR program MUST be running.
