A device that provides power to Android-based electronic equipment, frequently smartphones and tablets, while also incorporating a visible light source, often LED-based, is a charging apparatus. These units are typically connected via a USB cable to the Android device. The illumination feature serves either as a visual indicator of charging status or an aesthetic enhancement. For example, one might use such a device on a nightstand to easily locate a phone in the dark or to ascertain if the charging process is complete.
Such apparatuses offer the user several advantages. The visual indicator allows for simple confirmation that electrical current is indeed flowing. The light emitting from the charger can serve as a low-intensity nightlight, adding functionality beyond the primary purpose of electrical replenishment. Historically, basic charging mechanisms lacked visual confirmation; these advanced models provide users a greater sense of certainty and improved ease of use. These attributes contribute to an enhanced user experience.
