What are some common items savvy travelers bring with them (that less-savvy travelers don’t)?

Don’t forget a small power strip—ideal for sharing a crowded outlet in an airport, and a simple way to keep all devices close by once at a hotel. (Combine that with a Zolt—which powers a laptop and two devices with a charger the size of a lipstick—and it’s even handier.) Keep a photograph of your luggage and passport on your smartphone; lose either of them, and you’ll be grateful for the reference. Pack a scarf—always. And since calling Nespresso coffee is an insult to baristas everywhere, the best in-room alternate is the Aeropress, a nifty gizmo that’s portable, light, and makes killer morning joe almost anywhere.
