Many bedside alarm clocks include a USB charging port so you can charge phones or small devices alongside the clock; some models specify higher-current ports (for example, a 2 AMP or rapid-charge port).
Typical features include snooze (often with a top snooze button), dual alarms on several models, adjustable snooze timers, and in some units ascending or adjustable alarm volume.
Children's clocks often combine a sleep‑trainer light and nightlight color cues with soothing sounds, nap timers, and visual wake indicators so kids can learn when to stay in bed and when it’s OK to get up.
Some models include a projector that displays the time on a wall or ceiling and is often adjustable; projection units frequently also show date or alarm status on their built‑in display.
Reviewers commonly praise large, bright digits and simple controls, noting that many models are easy to set up and read; adjustable brightness and straightforward buttons are frequent positives in user feedback.
