The recommended amount is between 700mA for a Raspberry Pi Model A, and up to 2.5A for a Raspberry Pi 3 Model B (see ''Power Supply Requirements'' in The MagPi Issue 56, Page 39 .). The Raspberry Pi boards typically draw much lower amounts, between 200 and 500mA. Usage depends on what you''re doing with the Pi.

USB host and Ethernet boot can be performed by BCM2837-based Raspberry Pis - that is, Raspberry Pi 2B version 1.2, Raspberry Pi 3B, and Raspberry

3. Any 5V power source which can supply sufficient power (amps) may be used. The Pi will use the power it needs. This is the correct answer. The MotoTurbo Charger (like most power supplies is a voltage source, which means its output voltage is regulated. The amperage specification is just the maximum amount of current the supply

Using a freshly bought "5V/2.1A" rated power supply, I get undervoltage warning icon on both my Raspberry Pi 3s. I measure 4.75V at the USB . Try to use another cable in order to connect your power supply to your Raspberry Pi. My Pi 3b runs off a 7.2Volt 3600mA NiMh Rc-car powerpack.
