digital table clock

Digital table clocks typically use LED or LCD displays. Common size options cited include "jumbo" LED digits (about 1.8") and smaller LCD screens (around 1").

Many clocks include adjustable brightness or dimmer controls. Options range from simple high/low dimmer switches to multi-level settings (for example, three adjustable brightness levels) for comfortable nightstand viewing.

Several clocks include USB charging ports (including at least one 2‑amp rapid USB port). At least one model also offers Bluetooth and a built‑in speaker for audio playback in addition to USB charging.

Extra features found across models include ceiling or wall time projection with adjustable projectors, built‑in nightlights or wake lights, and calendar/date displays on some projection-capable units.

Clocks commonly use plastic or ABS housings and also appear in wood‑composite or wood‑laminate finishes. Some have fabric‑wrapped cases. Designs range from small round nightstand styles to fabric‑covered sound‑machine types.

Display and face colors shown across models include red, brown, blue, gray, and white, depending on the specific unit.

Battery backups are intended to preserve time and alarm settings during power interruptions. In most cases the backup maintains settings rather than powering full display or operation while the main power is out.
