What travel gadgets are actually useful and not just TikTok hype?

When filtering out transient social media trends, the most genuinely useful travel gadgets are those that solve real, repetitive friction points: dead batteries, high baggage fees, lost luggage, and lack of connectivity.

Rather than single-use gimmicks like footprint-shaping travel pillows or bulky portable washing bags, seasoned travelers rely on a core set of versatile, multi-functional tools. High-power GaN universal adapters replace multiple wall chargers, Bluetooth transmitters let you use your own comfortable wireless headphones with outdated in-flight entertainment, smart trackers provide peace of mind for checked baggage, and hybrid power banks ensure you stay charged on long transit days without carrying extra bricks and cables.
