Product Description

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: 3½" long x 1" wide x ½" 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 2–3 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.

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. (Posted on 9/14/2018)

This product is perfect for laptops or desktops that are within close proximity to you. Would be great in the car too. Doesn't cover a whole lot of space but it's perfect for your own bubble so your co-workers don't feel overwhelmed by your favorite oils! (Posted on 7/10/2018)

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. (Posted on 4/17/2018)

I tried multiple essential oils with different thicknesses and it never worked. I tried it in multiple USB ports (wall, laptop, desktop computer) and it never worked. I do not recommend this product.

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.
