Electrical currents and outlets differ by country. Before you depart, research electrical outlet styles in your host country. Laptops, cell phones, chargers, and all other electrical devices may require use of a plug adapter, and some devices may need a voltage converter. You can purchase converters and adapters at electronics and travel stores in the U.S. REI offers a World Electricity Guide on their website.
Small electrical appliances, such as hairdryers, sometimes have different voltage requirements that are not compatible with electrical grids overseas. Consider purchasing such items in the local voltage after you arrive in your host country. Increasingly, personal items like laptops, cell phone chargers, and electric razors are usable worldwide. Be sure to check compatibility in advance.
In some countries, digital snooping is commonplace, leaving your sensitive information vulnerable to theft. Prepare your device for travel by backing up your sensitive data and removing all information not needed for the duration of your program, updating security protections, and familiarizing yourself with local laws and security. Consider using WiscVPN (Virtual Private Network) to encrypt your information.
