Many outlet plugs have usb so it's not any problem plugging it in. Works very well, as the 30 minute run time does the job! But i find i often use it by plugging the usb cord into my computer, which makes the battery last longer.

Doterra diffuser is small, whisper quiet, and works well for a water-less diffuser. It emits the perfect level of oils applied to the felt pad. The scent isn't as powerful as a water diffuser but for size and application it's awesome!

As advertised, this is perfect for small rooms. Perfect size for an office desk or bedroom. The guest bathroom is very small and it works perfect in it.

Great diffuser. Cute minimalist design too. Such a cute little item.

Comes with a usb plus. Easy to use. Worthwhile purchase. Is just so convenient.

Not impressed with this purchase at all. Broke in under a month. Timer on the unit lasts for very short time. I guess if it actually was powerful enough to create air and scent the short timer is less of an issue.
