DreamSky 4" LED Alarm Clock Radio with USB Port

The DreamSky alarm clock radio is a bedside digital clock with a 4-inch large LED display, adjustable dimmer, FM radio, USB charging port, snooze and battery backup for reliable mornings.

Designed for everyday bedroom use, this DreamSky unit combines a very readable clock face with simple radio tuning, customizable alarm volume, and a built-in USB charging port so you can keep your phone powered at night. It runs from the included DC adapter with a 3xAAA battery backup to preserve time settings during outages. The display supports 12/24-hour modes and shows indoor temperature in either °C or °F.

How easy is the display to read at night or in bright light?

The clock uses a four-inch LED numeric display with a full-range dimmer wheel so you can set brightness anywhere from fully bright to completely off. That makes it easy to tailor the screen to your bedroom lighting without disrupting sleep.

• 4" large blue LED digits for quick time reading
• 100%–0% continuous dimmer control
• 12/24-hour time formats and temperature readout

What alarm and snooze options are available?

You can wake to a buzzer or the FM radio, and both alarm types have adjustable volume levels so the wake-up is not jarring. The alarm starts softly and ramps up over a few seconds; an eight-minute snooze can be repeated up to an hour until you turn it off.

• Buzzer with three volume settings
• Radio alarm with 15-level volume control
• Gradual alarm ramp-up and repeatable 8-minute snooze

Can I use the radio and will it help me fall asleep?

The unit includes an FM radio with simple tuning and a clear, built-in speaker. A sleep timer lets the radio play for a preset interval, so you can drift off without leaving it on all night.

• FM radio reception with manual tuning
• Sleep timer options from 10 to 120 minutes
• Speaker optimized for bedside volume levels

Is there a way to keep devices charged and the clock running during power loss?

Yes — a front USB port charges smartphones and small electronics without needing a separate wall plug, while the included DC adapter powers the clock continuously. Insert three AAA batteries (not included) for short-term memory backup when the power goes out.

• Front USB charging port for phones and accessories
• Included DC adapter with long 76-inch cord
• Battery backup (3×AAA) to preserve time and alarm settings

Who this is for: The DreamSky bedside alarm clock radio fits anyone who wants a straightforward, easy-to-read bedroom clock with flexible brightness control, simple FM radio functions and a convenient USB charging port. It’s suited to light sleepers who need gentle alarm ramping, people who prefer visible large digits across the room, and anyone seeking a compact clock that keeps settings through brief power interruptions.
