Science communicator Derek Muller of Veritasium released a video exploring how many portable power bank batteries could supply a human body's energy needs [1].
The experiment translates biological energy requirements into electrical terms to illustrate the scale of human metabolism. By comparing the caloric intake of a person to the watt-hour capacity of consumer electronics, the project highlights the efficiency and density of biological energy storage.
Produced in partnership with Anker, the video utilizes portable power banks to visualize the sheer volume of electricity required to sustain human life [1]. The collaboration serves as a promotional tool for Anker while providing a conceptual look at thermodynamics and energy conversion.
Muller examines the relationship between the food humans consume and the energy output required to maintain basic bodily functions. This comparison allows viewers to conceptualize the energy stored in a typical diet by imagining it as a series of physical battery packs [1].
While the video focuses on the theoretical application of power banks to human energy, it emphasizes the difference between chemical energy in food and electrical energy in lithium batteries. The project serves as a pedagogical tool to explain how energy is measured, and transferred, across different systems [1].

This comparison underscores the vast difference between the energy density of biological fuels and current consumer battery technology. By framing metabolic needs through the lens of portable electronics, the project makes the abstract concept of daily caloric expenditure tangible for a general audience.
