Yeah, it&#x27;s sad that so many people actually use USB ports at airports to charge their devices, without knowing what they are connecting their devices to. I don&#x27;t expect them to know better, but all their data could be copied, stuff could be modified. Isn&#x27;t there an adapter which limits the active lines to just what&#x27;s needed to pass power, no data, or is charging without some data exchange impossible?
