Hi Seb Again,
I looked in the spec's, and to give you an idea about the required
power:
Max for RFM12 = 24 mA and for the RFM70 = 23 mA.
But it is possible by transmitting with lower power, and it wil not be
transmitting 100% of the time.
When the Receiver is active current for the RFM12b is 13 mA and for
the RFM 70 = 20 mA.
Beside this, there are Standby and power-of modes (currents < 1 mA).
