Packing the right travel gadgets for a long flight can make the difference between misery and comfort. Tablets and e-readers can provide hours of entertainment, while noise-cancelling headphones can help you tune out the world, and a smart bag or portable power bank can keep everything charged even if you’re stuck on a long layover.

Before you take off on your next long flight, check out all of these great gadgets that can keep you entertained, increase your productivity, and enhance your overall travel experience.

Smart bags have features that can be useful on a long flight, such as built-in device charging, GPS tracking, app-controlled electronic locks, and wireless connectivity. You’ll typically be replacing your standard carry-on with a smart bag, so choose one that meets the relevant size restrictions.

Since smart bags typically have built-in device charging, you may not need to pack a separate power bank. If you do pack a power bank, be aware that airlines have restrictions on the battery capacity you can bring in your carry-on luggage, so don’t exceed that limit without first getting explicit permission from the airline.
