I have read on the Raspberry Pi Foundation's website and forum that RPi Model B rev 2 should not get more than 1200mA of power on a 5V power source. This post (Safe to power a raspberry pi from a 50W adapter) confuses me. Someone here is saying a single RPi board can handle 10A (10,000mA) on 5 volts. Can the Raspberry Pi handle 10Amps? My Element14 manual/data sheet states that I should not give the RPi board more than 1200mA, but many places on the Internet state otherwise.
The Raspberry Pi will only take as much current as it needs, assuming the voltage stays at 5 volts. A power supply with a higher current rating just means there is more power available than is really needed.
It's not clear what the 10 amp figure is referring to. The RasPi board cannot come anywhere close to providing that amount of current from its ports, so you'll need to clarify what you mean by 'handle'.
