smallest digital clock

Reported weights in the sample range from about 0.25 to 0.63 pounds (≈4 to 10 ounces). Individual entries also appear listed as 8 ounces and 200 grams (≈0.44 lb), so most compact models fall roughly within that range.

Many compact clocks are plug-in (electric) with a battery backup option. Listed backup batteries include 1 AA, 2 AAA, 3 AAA (as backup), or a single CR2032 lithium cell. Some product pages also note batteries are optional or not included.

Sample dimensions show heights from 1.76 to 5.00 inches, widths from 1.00 to 5.90 inches, and depths from 1.85 to 6.30 inches. These ranges reflect the variety of compact bedside designs in the selection.

The selection includes both LED and LCD displays. Adjustable brightness is common—many models offer multiple brightness levels (often three), night/dim modes, on-demand backlights, or the ability to turn the screen off for dark rooms.

Compact clocks can include extras such as a USB charging port, time projection (adjustable to wall or ceiling), integrated nightlights (white, color, or color-changing), wake‑up light functions, and sound/sleep features—especially on kids’ models.

Several plug-in clocks include battery backup to preserve time and alarm settings. Backup battery types mentioned include 1 AA, 2 AAA, and a CR2032 lithium cell; one listing specifies AAA batteries back up the clock’s time only.
