Extra Loud 115dB Alarm for Deep Sleepers

This alarm clock delivers a 115dB signal with six selectable tones, designed to wake heavy sleepers who miss standard alerts. Students, shift workers and anyone who struggles to rise on time will benefit from the volume and variety. The 4.2" LED display offers adjustable brightness for day or night viewing.

Replaces Quiet Clocks and Phone Alarms

If your current clock or smartphone alarm fails to rouse you, the 115dB output and dual-alarm function provide a decisive upgrade. The jump is worth it when you need two separate wake-up times for shifting schedules or a reliable backup during power cuts thanks to AAA battery memory retention. A nine-minute snooze adds flexibility.

Check Power and Space Before Buying

The unit runs on AC 100–240V at 50/60Hz and requires a mains outlet; batteries only preserve settings and sound the alarm during outages. The USB port charges a phone but does not charge the backup cells. Verify you have a bedside socket and enough surface area for the compact footprint.

Questions about this item

What size nightstand space does the 4.2" display unit need?

The compact footprint fits on a nightstand, desk or dorm bedside without crowding the surface.

How do I set the dual alarms and 9-minute snooze correctly?

Set two separate alarm times, choose 12 or 24-hour format, pick one of six sounds, then press snooze once for a 9-minute delay.

When must I replace the AAA backup batteries?

Replace AAA batteries when the memory backup fails during a power outage; they only retain settings and alarm, not display or USB charging.
