The clear red time is projected onto the wall or ceiling at a distance of 2-3 metres.

Multifunctional settings and 12 or 24 hour display: in addition to the alarm function, you can also use this multifunctional projection clock to display the time, room temperature, date, day of the week and month, as well as the weather. It supports both 12-hour and 24-hour displays. The LED display shows the time clearly, even when backlit, so you can easily see it at night. Dual Alarms And Snooze: The digital projection alarm clock has two independently adjustable alarms, so you and your partner can set different wake-up times without having to reset them each time. In addition to setting different alarm times, you can also set different snooze times (5-60 minutes) and ringtones (bu or rd). The alarm clock will remind you again after you have slept a little longer to avoid oversleeping. USB connection and battery operation: This projection clock has two power supply modes.

(Note: the alarm clock cannot be used with high-capacity alkaline batteries please use normal carbon batteries.)
