spare battery: When the white noise machine stops the music after the power is turned off? Our improved white noise machine is equipped with an 1800mAh, 6.66Wh (47.1 grams) rechargeable battery, which can provide up to 10 hours of use to help your baby fall asleep and sleep longer, whether for naps or at night. Noise Protection: Twenty-four high-fidelity sounds (lullaby, natural music box sound, birth sound, humming, stream sound, white noise, buzzing, fan sound) allow you to choose the ideal background to block out distractions and create the perfect environment for work, study, sleep, or a restless baby. Small, colorful nightlights: A soft, adjustable LED lamp can provide ample but less glaring light in your room at midnight. There are also 7 RGB color ambient light products – steady or breathing rhythm – ready to meet your personal preferences. Simple setup & automatic timer shut-off: No two functions share the same button. Even in the dark, it's easy to adjust and change settings or the volume. The automatic shut-off timer (30, 60, or 90 minutes) allows you to turn off this white noise machine and enjoy a peaceful night. During sleep, it remembers the last sound and volume setting when restarted. Safety: CE, FCC, and RoHS certified, this sleep device is made from non-toxic, flame-retardant, and odorless materials. To ensure the daily safety of your newborns, toddlers, and children of all ages
