Auto-set bedroom clock

The DreamSky DS305B is a mains-powered LCD alarm clock that sets itself to the correct US time the moment it is plugged in. A 4.3 inch screen shows the time, calendar date and indoor temperature in blue digits. Four US time zones and automatic DST adjustment are selectable during setup.

Mains power with USB charging

The unit requires the included DC adapter connected to its first USB port to operate and display the time. A backup button cell preserves settings during a power cut but does not drive the display or sound the alarm. The second USB port supplies power for charging a phone, tablet or MP3 player.

Replaces manual-set clocks with no backup

This model suits anyone who wants to stop resetting the time after every outage or seasonal change. It is not for buyers who need battery-only operation, a projection display, wireless connectivity or multiple independent alarms.

Questions about this item

Should I pick the 4.3 inch LCD or a smaller display?

This model only comes with the 4.3 inch LCD, so there is no smaller display option to choose.

How bright is the screen at night with the dimmer turned down?

The 0%-100% adjustable dimmer lets you lower the blue digits to a comfortable level for dark rooms.

What does the USB port actually power?

One USB port runs the clock via the included DC adapter; the second port charges phones, tablets or MP3 players.
