6.7-Inch LED Desk Clock

This KOSUMOSU alarm clock features a 6.7-inch mirror-style LED display showing white and sky-blue digits. It presents the time in 12 or 24-hour format, seconds, date, day of the week, and indoor temperature. Dual alarms with three cycle options suit workdays, weekends, or daily schedules. The unit is designed for bedside, desk, or shelf placement in bedrooms, living rooms, or offices.

Check USB Power and Adapter Needs

The clock requires a constant 5V/1A USB-A power supply to operate and does not run on batteries. You must provide a compatible AC adapter separately as one is not included. Ensure a USB power source is available at your intended location before ordering. Verify that your outlet setup can accommodate a plugged-in device continuously.

Thermals Noise and Power Draw

The device draws low power from a standard 5V/1A USB connection during normal operation. An integrated light sensor enables automatic display dimming based on ambient conditions, while manual settings allow low, medium, high, or display-off brightness levels. The clock operates silently with no moving parts or audible fan noise. LED brightness adjustments help manage heat output from the display.

Questions about this item

Does the clock come with a power adapter or do I need to buy one separately?

The clock requires a 5V/1A AC adapter that is not included, so you will need to purchase one separately.

Which display size should I expect — the 6.7-inch or 6.4-inch figure?

The product is described as a 6.7-inch mirror-style display; the physical dimensions are 6.4 in x 3.81 in x 3.3 in.

How bright are the blue digits in a dark bedroom?

Auto dimming via a light sensor and four manual levels (low, medium, high, display off) let you reduce the blue digits to a comfortable night-time level.
