What is the Anker 'smart display charger' and what does that screen even do?

Anker’s plug-in wall chargers display temperature, charging mode, status, real-time wattage and battery progress for supported devices, enabling overheating or low-power diagnosis. They feature an interactive “charging buddy” that reacts to touch. The 45W Nano Charger includes Care Mode, reducing temperatures up to nine °F, while all models use PowerIQ and ActiveShield, conducting three million temperature checks daily.
