It's risky to rely on hotel alarm clocks and wake-up calls - sometimes they don't work! It's safer to take your own travel alarm clock, and then you get the kind you like, too - digital or analog, atomic clocks, night light clocks, even clocks with photos!
Less than 2" square, this tiny alarm clock has luminous hands plus dial light, snooze feature, and an alarm that gets louder and faster if ignored. Takes one AA battery (not included).
This handy travel clock is pre-set, so just the turn of a knob automatically sets the time anywhere in the U.S., U.K., Europe and Japan. Solar-powered, it features a giant screen display.
