A power adapter and cable, typically employing a Lightning or USB-C connector, provides the electrical energy to replenish the battery of Apple’s mobile operating system-based devices, such as iPhones and iPads. For example, connecting the adapter to a wall outlet and then connecting the cable to both the adapter and an iPhone allows for the device’s battery to recharge.
Efficiently supplying power is paramount for maintaining user productivity and ensuring device longevity. Historically, these accessories have evolved alongside the devices they support, adapting to faster charging standards and changing connector types to improve user experience and energy transfer rates. The development reflects advancements in power delivery technology and design considerations for portable electronic devices.
