What is a battery-powered device used by customers onboard the aircraft?

The identification of a battery-powered device used by customers onboard the aircraft as a Portable Electronic Device is accurate because it encompasses a wide range of gadgets that travelers commonly use, including smartphones, tablets, and laptops. These devices are designed for personal use, allowing passengers to stay connected, entertained, and productive during their flights. Portable Electronic Devices are widely recognized by airlines for their function and the need for operational guidelines related to their use during different phases of flight.

While a power bank can also be considered a battery-powered accessory that assists in recharging electronic devices, it is not classified as a device by itself but rather as an accessory that supports other devices. The In-Flight Entertainment System is an integrated system provided by the airline for passenger entertainment, and while it may be powered by batteries or onboard power, it is not a device that customers bring onboard themselves. A mobile charging station refers to a specific setup that may be available in the aircraft but is again not a device used directly by passengers. Thus, the broad classification of Portable Electronic Devices aligns with the intended context of customer usage onboard.
