Adapters and converters are essential for any traveler that intends to use electronic equipment, such as a computer, cell phone, hairdryer or electric razor, on a trip outside of the United States. Adapters provide a way to link pieces of equipment that cannot be directly connected due to outlets with differing configurations and sockets. The devices simply plug into the wall, then the electronic equipment plugs into the adapter. Adapters and converters can be purchased separately or as part of a complete set. Because they are small and compact, they can easily be tucked inside a briefcase or tote bag. Many even come with a carrying case for easy packing.
