Super sleek and portable, the USB Diffuser works in any USB computer connection! You can also use it in any room with a standard outlet power converter, or take it in the car with an accessory outlet power converter (converters not included). Ultrasonic technology silently transforms essential oil into a cool mist for aromatherapy just about anywhere, day or night. This diffuser offers 3 timer settings for controlling mist output, allowing the oil reservoir to last 24 hours or more.

Contents: Portable diffusing unit, 1 refill bottle, and 1 small cleaning dropper.

Dimensions: 3" long x 1" wide x " deep.


  • Small, portable size and shape.
  • Standard USB port connection.
  • Silent operation.
  • Cold-mist ultrasonic diffusion.
  • 3 timer/output settings (misting every 10, 30, or 60 seconds).
  • Long-lasting output (up to 25 hours at 60-second intervals).
Instructions: Fill the bottle with essential oil, insert it into the diffuser, slide the lid in place, and plug the diffuser into any USB port. To clean, unplug the diffuser and remove the oil bottle. Use the small cleaning dropper to put 23 drops of alcohol into the ultrasonic disc (where mist exits). Plug the diffuser in, choose the 10-second setting, and run the diffuser until all the alcohol has dispersed. Unplug the diffuser, insert the filled oil bottle, and operate as usual.

Not worth it May 31, 2016
Reviewer: Anonymous Person from Spring Hill, TN United States  
Was so excited to get this for my hubby to use at work. Got him the Elevation blend to use. The diffuser worked a few months and now won't do anything.  It still shows it has power but nothing is working. Wish this could be disassembled to clean. I fear it's clogged.

Disappointed October 6, 2014
Reviewer: Anonymous Person from Flagstaff, AZ United States  
Love the idea but the product is poorly made. The oil bottle is very difficult to remove. I ended up breaking part of it to remove the bottle so now have to tape the cover on. It still functions though.

Works fine with Breathe January 16, 2014
Reviewer: Kristina from Woodstock, GA United States  
This is my first diffuser so I can't compare it with a regular sized one, and I've only had it for a couple of weeks, but so far I'm happy with it.

Depending on your USB port, the hole that dispenses the vapor may end up facing away from you. However, it does diffuse (I'm sure on a much smaller scale than a bigger one) and it handles Breathe just fine.

It does clog up and stop working but the fix is incredibly easy -- per instructions (which are so tiny as to be virtually illegible), you just take the oil bottle out of the diffuser, drop one drop of water on the hole on top of the diffuser, and plug the empty diffuser in for a minute or so. I thought "yeah right" but it totally did the trick!

It is a flimsy little thing so I wouldn't be surprised if it breaks or stops working any day now, but I've used it on and off for a couple of weeks and I think it's helped.

I will buy the extra refill bottles so I can use different oils without having to try to clean the bottles.

Doesn't Work with Blends December 5, 2013
Reviewer: Anonymous Person from Worthington, OH United States  
This does not work with blends like Citrus Bliss, Balance etc. because they are apparently too thick. I did get it to work with singular EO's like Lemon.
