Abstract

A power adapter with charging data display provides power to a battery of a communication device. The power adapter displays numbers and a progressive lighting system, such as LED lights, to indicate a power transfer rate, an estimated recharge time, and a completed charge time of the battery. In this manner, the charging status of the battery is made known, and the battery will not be overcharged, causing damage to the battery. A current detecting circuit detects a charging current passing through the battery, and derives a detected current signal. A voltage detecting circuit detects a charging voltage generated at the battery, and derives a detected voltage signal. Software calculates the power transfer rate, estimated recharge time, and completed charge time of the battery based on the detected voltage signal and detected current signal. A label panel includes apertures and labels that identify each of the charging data.
