Technology is sure making our lives more convenient. However, choosing which devices to pack on your travels can be quite a challenge. To help you sort this out, we asked experts who sell electronics which gadgets are must-haves for frequent flyers.

1. Universal Adapter

If you’re a frequent global traveler, you fully grasp the value of bringing a universal adapter. These days, you can buy universal adapters with multiple USB ports so you won’t have to bring a charger for your smartphone and tablet separately.

2. Wi-Fi Router

Most hotels around the world offer wired internet access at no cost. However, they charge for Wi-Fi access often on a per-gadget basis. You can either pay for the extra charge or you can bring your own Wi-Fi router. Some Wi-Fi routers today can even be directly plugged into the wall.

3. Extension Board

If you travel a lot, you may have noticed that hotels often lack power points. And, if they have more than one, the sockets are often hidden under the bed or positioned on the other side of the room. Bringing an extension board makes this problem go away. An extension board gives you several power sockets accessible wherever you are in the room. To save luggage space, buy a circular board with a retractable wire.

4. Noise-cancelling Headphones

If you spend most of your time in an airport somewhere around the world, investing in a good pair of noise-cancelling headphones is a smart choice. The Boss In-Ear Noise-Cancelling Headphones is a favorite of many. But if you are on a tight budget, the Quietcomfort 15 Acoustic Noise Cancelling Headphones is on sale for half as much via Amazon.com. Also, buy headphones with an in-flight adapter.

5. EBook Reader

For bookworms, purchasing an eBook reader solves the problem of which books to bring. Most eBook readers also offer a seemingly endless battery life which makes it the perfect companion for delayed flights or layovers. To make it pretty sweet, buy the current-generation Amazon Kindle.

6. Battery Bank

Even the smartest gizmos are useless without power. While many airplanes, trains, and buses now feature power sockets for charging gadgets, there’s nothing like having a portable battery bank on hand. This is helpful if you’re planning on having a long day on the road or exploring the wilderness for days.

The market for battery bank these days is massive. You can choose from a variety of capacities like a couple of thousand mAh that can supercharge your phone at once or a 20000mAh monster that can last for weeks.

7. Entertainment On-the-Go

If reading isn’t your thing, you can enjoy TV shows or movies using your mobile device. To make it better, bring your Apple TV with you. For Android users, take advantage of AirPlay. If you’re on a budget, try the Amkette Evo TV, which connects to your smartphone via a DLNA. Another not-too-expensive choice is Google’s Chromecast. And while most hotels now have HDMI cables, bring one with you just to be safe.

With all these gadgets, flying to different parts of the world will be much more enjoyable.
