Does it really use only 1.2 Amps?. I am reading the documentation and almost all raspberry pi use 3 Amps. Tnx
Yep! They suggest using a 3A power supply so that there is enough power for USB peripherals and also to add a bit of leeway, but if you look around at tests people have done, the Pi itself typically uses 1-1.5A.
