The component allows for replenishing the power source within a Texas Instruments TI-84 series graphing calculator. It commonly features a USB interface, facilitating connection to standard power adapters or computer ports for recharging the device’s internal battery. An example of its use involves connecting the calculator to a wall outlet using a compatible USB power adapter to restore power depleted through regular use.
Availability of such a component extends the operational lifespan of the calculator, reducing reliance on disposable batteries. This provides a more environmentally conscious and economically sustainable approach to powering the device. Furthermore, widespread adoption coincides with the increasing prevalence of USB-based charging solutions for electronic devices, leading to greater user convenience.
