Opt for a durable and spacious suitcase or backpack with multiple compartments for efficient packing, packing cubes to keep your clothes and items organized, and a waterproof pouch to protect your valuables from unexpected spills or rain. If you travel frequently you may want to invest in a set that's going to last.
Packing a neck pillow for better rest during long flights or train rides is a must. Don't forget a first aid kit with essential medications, and a portable travel lock for added security in accommodations..
Rule of thumb is for every device have 2 chargers. If one fails you'll have a backup. Don't forget to bring a universal adapter to charge your devices in different countries, a power bank for staying connected on the go, and a lightweight, versatile camera to capture memories.
