Dual-Power Clock for Any Room

The Emerson KW588 alarm clock runs on four AA batteries or the included USB cable, so it works on a nightstand, desk or RV shelf without a nearby socket. Settings are retained automatically when the power source changes. A built-in light sensor dims the display at night and brightens it by day, with three manual levels as an alternative.

Suits Light Sleepers and Travelers

The gradual alarm starts quietly and increases in volume, while a top-mounted snooze button grants seven extra minutes up to three times. Large LED digits in blue, red or green are legible from across the room, helping seniors and children read the time without glasses. Buyers who need projected time, wireless charging or smart-home integration should look at other models.

Battery or USB Operation Decides Placement

Choose battery power for completely cordless positioning or USB power for continuous use without replacing cells. The clock measures 6.3 by 3.81 by 2.5 centimetres and weighs 0.2 kilograms, fitting tight surfaces. Time accuracy stays within 30 seconds per month in either 12-hour or 24-hour format.
