This is the portable projection clock that displays the time and date on a wall or ceiling. Unlike standard projection clocks that are too bulky to haul on a vacation or business trip, this unit folds to the size of a wallet (4 1/2" L x 1" W x 3" D) and can be easily stowed in a backpack or suitcase. A button on the front of the clock activates the self-focusing projection that displays the time on any flat surface up to 15' away and illuminates the clock’s LCD backlight for a ten-second-long nightlight-like glow. With a 90° adjustable projection arm, 12- or 24-hour time display option, and USB port for charging smartphones or other electronic devices. Powered using an included USB cable or two AAA batteries (required). Open 4 1/2" L x 3" W x 3" D. (8 oz.)
