When traveling with a computer, consider the varying power services in other countries. Because laptops use batteries, you won't need to worry about using a converter; the power supply in other countries will charge your computer as usual. You'll need adapters, however, to plug your cord into foreign outlets. Buy a universal adapter to reduce the need for many different pieces. Bring a surge protector to guard your computer against unpredictable power grids, particularly in developing countries.
Most travelers with laptops use wireless networks; when using wireless Internet on a network that is not password-protected, be cautious about information you send. Avoid logging on to banking websites, for example, where the data you transmit can make you vulnerable. Most newer laptops come with built-in Wi-Fi network cards; you can also pack a USB wireless signal booster to improve speed on weak Wi-Fi networks. If you plan to spend a lot of time in a single country, consider getting prepaid mobile broadband service, available in many locations around the world. This service, which is best purchased in-country, comes with a USB modem that gives you wireless access anywhere, though coverage within cities is usually the strongest.
When traveling in developing countries or dangerous locations, avoid packing your computer in an obvious laptop bag, which can make you a target for thieves. Instead, look for a nondescript canvas messenger bag, which is easy to keep in front of your body for safety reasons. To protect it from the inevitable bumps and jostling that happen on buses, trains and planes, store your laptop in a protective padded case. Bring a cable lock that you can fasten to a heavy object when you must leave the computer in a hotel or hostel, and bring a padlock to store it safely in a locker.
Computers can make your life easier and more entertaining when on the road, particularly if you have the right accessories. Bring an external hard drive to back up photos and data in case your computer is damaged. USB drives can prove useful for transferring files from your computer to another. Pack a headset with microphone for interference-free online calls, headphones for watching movies and an external mouse if you plan to do extensive professional work like photo editing or design.
