Compact bedroom clock

The DreamSky DS312 is a mains-powered digital alarm clock with a 5.3 inch wide case and 2 inch high blue LED digits. It suits anyone who wants a clear time readout without a bulky footprint on a nightstand. The 110-240V adapter and 4.1 ft USB cable are included in the box.

Build and daily use

The black plastic case measures 5.3 in by 1.4 in by 2.6 in and sits flat on a bedside surface. A single USB-A port on the back provides 5V charging for a phone or small device so you can leave a separate charger in another room. Two AAA cells (not supplied) keep the time and alarm settings during a power cut, but the display stays dark and the alarm will not sound until mains power returns.

What the extras change

The bundled AC adapter and long USB cable mean the clock works straight from a wall socket without hunting for a spare USB brick. Adjustable alarm volume between 30 and 90 dB lets you pick a level that wakes you without being harsh, while the 9 minute snooze and a simple on/off switch make weekend mornings easier. The dimmer lets you lower the blue digits so they do not disturb a dark room.

Questions about this item

What plug standard does the included adapter use?

The adapter uses a US plug and works on 110-240V mains voltage.

How much depth does the clock need on a nightstand?

The unit is 2.6 inches deep, so allow at least that much flat surface space.

How do you keep settings during a power cut, and what is the common mistake?

Insert 2 AAA batteries for backup; the screen stays blank on battery power and the alarm will not sound until mains returns.
