Digital Radio Clocks

Start with the radio and wake-up functions you will actually use. Current models range from AM/FM clocks with loud alarms to dual-alarm units with weekday settings, sleep timers, station presets, and automatic time setting. For a dark bedroom, compare digit size, color, and how far the dimmer can turn down. Battery backup can preserve time and alarm settings during an outage, while USB ports can charge a phone. Night lights and sound-machine modes add convenience, and one option adds ceiling projection and room sensors. Check the controls and display layout before choosing a feature-heavy clock.
