Power draw refers to the amount of electricity a device or system consumes or the amount of current it draws from a power source. There are several synonyms for power draw including power consumption, current drain, energy usage, electrical load, and electricity demand. These terms are often used interchangeably depending on the context. Power draw is an important consideration for electronic devices and systems because high power consumption can result in heat generation, decreased battery life, and increased costs. Manufacturers and engineers typically strive to reduce power draw in order to improve efficiency, prolong battery life, and reduce environmental impact.
