6.7-Inch LED Clock with White and Blue Digits

This KOSUMOSU digital clock features a 6.7-inch LED display showing white and sky blue digits on a black case. It provides time in 12 or 24-hour format, date, day of the week, seconds, and indoor temperature in Celsius or Fahrenheit. The unit measures 6.4 in by 3.81 in by 3.3 in and is designed for bedroom, classroom, or living room placement.

Auto and Manual Dimming with Dual Alarms

The clock offers automatic dimming plus four manual brightness levels including display off. Two independent alarms each support three recurrence modes for workdays, weekends, or daily use, and a snooze function is included. A button cell retains time and settings during power interruptions but does not run the display.

USB-Powered Desk Clock for Indoor Use

This clock requires a 5V/1A USB-A adapter which is not supplied in the box. It suits buyers wanting a plug-in LED clock with calendar and temperature readout. It is not suitable for anyone needing battery-powered portability, wireless connectivity, or a larger display such as the 9.7-inch models in the same series.

Questions about this item

How long does the button battery last before it needs changing?

The included button cell only keeps time and settings during a power cut; it is not a continuous power source, so replace it when the clock loses time after an outage.

What limits continuous operation of the 6.7-inch LED display?

The clock must stay connected to a 5 V 1 A USB-A adapter; without mains power the display turns off and only the backup cell retains the time.

Does the auto-dimming feature reduce heat or fan noise when the clock runs all day?

There is no fan; the LED panel runs cool, and auto or manual dimming (low, medium, high or off) only changes brightness, not temperature or noise.
