Low power warning in Raspbian. The Raspberry Pi can function on a lower supply, but it may have problems when you start to do demanding tasks or add peripherals. The Raspbian operating system comes with a low voltage indicator icon. This yellow lightning bolt appears in the top-right of the screen. It is used to indicate an under-voltage warning.

    The devices need to be electronically compatible with the Raspberry Pi hardware since the Raspberry Pi Board B provides 140 mA maximum to each USB port before the polyfuse trips. In addition, due to the simplistic power design of the Pi there are issues concerning the resistance across the polyfuse and the voltage drop they cause.
