Any person traveling and plugging in their high priced laptop computers at the airport, the hotel, or their favorite restaurant is taking a big risk. A big electrical surge from a thunderstorm could fry the computer in an instant. The Tripp-Lite Traveler100BT provides a critical layer of surge protection. It has good specs and should do the job if called upon. The only complaint I have, albeit minor, is that it is a little bulky when stuffing it into a zippered pocket somewhere. This is a first rate product and highly recommended.
