The purpose of this document is collecting some generic techniques about how to lower the power consumption of Raspberry pi's. The name 'pile' comes from 'Raspberry Pi, low energy'.
This table represents some measurements of the power consumption of Raspberry Pi zero W connected to WiFi, with no other USB devices, or other peripherals connected. These measurements have been taken from a Portapow premium USB + DC Power Monitor.
