Silent Vibration Alarm for Deep Sleepers

The ifundom 2738S23RMA wristband uses a strong tactile motor to wake heavy sleepers without any audible sound. The discrete alert stays on the wrist so partners, roommates or colleagues are not disturbed. A simple USB 2.0 charge keeps the 50 mAh cell ready for daily routines or travel.

Sustained Daily Use and Battery Life

The 50 mAh battery delivers multiple vibration cycles on a single charge so the band remains reliable across consecutive mornings. Silicone construction resists sweat, rain and spills while the 255 mm strap stays secure during sleep, sport or all-day wear. Real-time temperature and step data update continuously without interrupting the alarm function.

Upgrade from Audible Clocks and Basic Bands

This replaces a loud bedside alarm or a simple step counter that lacks silent wake-up. The jump is worth it when you need a vibration-only alert, on-wrist temperature reading and sleep-duration tracking in one lightweight 0.06 lb device. Buyers who want heart-rate monitoring, GPS or smartphone notifications will not find those features here.

Questions about this item

Does the 50 mAh battery last through a full day of step counting and sleep monitoring?

The 50 mAh cell powers the pedometer, sleep tracker and vibration alarm for multiple uses on one charge, and it refills over the USB 2.0 connector.

What must I own to charge the wristband?

Any standard USB 2.0 port or adapter supplies the power the band needs; no proprietary dock or cable is required.

Will the vibration alarm work if I keep my older feature phone instead of a smartphone?

Yes — the alarm, step counter, temperature display and sleep monitor all run on the band itself with no phone pairing needed.
