Travel clocks ensure that anyone taking a trip, whether for business or pleasure, has an accurate device to measure time. This inexpensive, compact travel accessory will easily fit inside a handbag, briefcase or side compartment of a suitcase. Many come with a protective carrying case or have a flip-top. Battery operation makes it portable, operational in a power outage or any location away from an electrical outlet, such as on the beach or when riding in a cab. Traditional analog styles have glowing hands for nighttime viewing, while contemporary digital models are backlit with LED lights to make numerals visible. Extra features may include a snooze function, varying alarm tones, date, day of the week, temperature and multiple time zone readings. Some even do double-duty as a flashlight, calculator, currency exchange device or stopwatch. Travel clocks guarantee that the operator never misses a flight or sleeps through a meeting, due to a faulty hotel clock or a mishandled wake-up call.
