This versatile essential oil diffuser from Sonder is a must for aromatherapy on the go. Its rechargeable lithium-poly battery is ideal for extended use away from an outlet while the charging base is perfect for all universal wireless charging. Simply add a few drops of your favorite essential oils and carrier oil to the 200ml waterless chamber and let the sleek tower design spread soothing scents up to 1000 square feet for 14-24 hours. Control scent and light settings from the included remote or app for personalized aromatherapy wherever you go. Its quiet operation won't disturb sleep or conversation, while waterless technology keeps oils fresh and contaminant-free. Recharge the battery in just 4-6 hours and enjoy cordless, spa-like aromas anywhere in your home or office throughout the day without the need to stay near an outlet. Cold air nebulization has also proven to be a healthier way to experience essential oil aromatherapy versus burning the oils. The 10-15 dB pump is far quieter than other competing products. This means that your relaxing time can actually be annoyance free.
