The Pi 2 draws less than 500mA with nothing connected but the red light "not enough" power will blink. Plugging a usb cable to an apple charger doesn't get you 2A of power. It seems the charger won't let go of that much power unless it feels something on the data port. So those lines aren't merely to notify the device of how powerful the charger is but it works the other way around too and the charger presumes the device is 500mA unless it uses the data ports correctly | |
