Colorful Display & RGB Night Light This digital alarm clock features a vibrant, rainbow-colored display and a color-changing night light, ideal for bedrooms. The brightness of both the display and night light can be adjusted to suit your preference. Designed for bedside tables or bedroom decor, it offers a range of solid colors and dynamic RGB lighting effects, allowing you to customize the look with various display hues and finishes. 6" Large LED Display The clock has a large 6 by 2.6-inch illuminated LED display that is easy to read from over 20 feet away, even in daylight or at night. The big digits are especially helpful for those with difficulty seeing small numbers, eliminating the need to strain or search for glasses. Display color can be changed, and the brightness is adjustable. A dimmer setting is available for reduced light output during nighttime to avoid disturbance. Snooze Function and 5 Alarm Volume Levels The LED alarm clock produces a clear, continuous beep (55dB-95dB) that can be heard from over 20 feet away, making it effective for waking children and teens. The alarm can be silenced or snoozed with a button press, providing an additional 1 to 15 minutes of rest each time. Easy Setup and USB Charging Port Designed for simplicity, the alarm clock has clearly labeled buttons for setting the time and alarm, along with a physical dial for adjusting display brightness. The top-mounted buttons allow easy access and visibility while setting. It also includes a USB port to charge smartphones or other devices overnight. Mains Powered with Battery Backup Powered via included DC adapter. Requires two 1.5V AAA batteries (not included) to retain time and alarm settings during power outages. Note: During backup battery use, the screen will turn off and the alarm will not sound.
