White Noise Machine 21 sounds, 1800mAh 🔊

This compact white noise machine from SURFOU helps create a calmer sleep environment for babies and adults, combining 21 soothing sounds with an adjustable night light and a large rechargeable battery for use at home or while travelling. It is aimed at reducing ambient noise and supporting naps or overnight sleep, with memory function and a child-lock to keep settings fixed.

Key Points

The device includes a wide selection of sounds, from five white noise variants to natural recordings such as ocean waves, rain, brook and birdsong, plus two lullabies and womb sounds. A simple timer offers 30, 60 and 90 minute options or continuous play, and the memory function restores the last used sound and volume when switched on again. For night feeds or gentle illumination the adjustable night light is convenient and unobtrusive. A child-lock on the rear prevents accidental changes, and the supplied lanyard and loops allow attaching the unit to a pram, car seat or suitcase.

Practical Tips

Place the machine at a moderate distance from the sleeper so the chosen volume sits within the recommended range of around 50 to 60 dB for night use, according to the manufacturer for a safe sleeping level for infants. The memory function is useful when using the same sound each night because it removes the need to reselect settings. If you plan to travel, charge the unit fully before departure and use the lanyard to secure it to a carry item to avoid small hands reaching the controls.

Positive Aspects

The larger 1800 mAh battery offers substantially longer run times compared with smaller 500 mAh alternatives, which can be helpful for overnight use or extended naps away from mains power. The neutral design blends into different rooms and the adjustable light supports quiet night-time tasks without bright overhead lighting. Note that very high maximum volume may not be required for most situations and should be adjusted carefully for infant use.
