More info

The Keylia Power USB ultrasonic essential oil diffuser looks after your essential oils as it diffuses cold. Enjoy all the benefits of your essential oils right next to you.

With its 3 different diffusion power levels, it emits small jets of mist at regular intervals and lets you adjust the diffusion effect.

Thanks to its misting technique, it can diffuse over up to 10m².

Operating principle

How to use your USB KEYLIA POWER diffuser:

Then, simply press the button to turn on the diffuser. A red light confirms diffusion once every 10 seconds.

A third press displays a blue light that represents diffusion once every 60 seconds.

User tips

The diffuser can be used on battery or USB power.

Do not connect the device to any other power source.

Do not place the reservoir wick or the reservoir itself on surfaces sensitive to oil corrosion.

Only use the Keylia Power reservoir in this unit.


In case of extended non-use of your diffuser, or simply for the sake of regular maintenance, it is advisable to clean your Keylia Power.

First, turn off and unplug your Keylia Power.

Next, clean the diffuser with a cotton bud dipped in alcohol: the outside parts, the bottle location and the cap head.

Wash your hands after cleaning.

Any essential oils that have not been diffused and remain on the metal diffusion disc can block the diffuser if they dry up.

To clean, place 1 drop of alcohol on each side of this diffusion disc, then fill the bottle with alcohol and let the diffuser operate normally for 5 minutes.

The essential oils remaining in the wick can dry out and block its capillary action. To clean it, soak the wick in alcohol to dissolve the dried oil or replace the wick if cleaning does not work.

Precautions for use

Do not swallow. Avoid contact with the eyes. Keep out of reach of children. Do not pour onto a flame or heat source. Do not use for children under three years old. For pregnant women, seek advice from a specialist. Never diffuse for more than 5 minutes in a child's room.
