The flame isn't real. The combination of the LED lights and the water vapour from the diffuser create an ultra-realistic simulation flame effect.
To power the diffuser, simply plug the USB cable into the back of the device and any suitable power source.
Fill the water tank up and add 2 or 3 drops of your favourite essential oil, perfume or cologne and you are good to go!
How long will it run for?
The diffuser can run nonstop for 8-13 hours depending on the location and humidity of the room!
The best part is that it will automatically turn itself off once the water tank is empty!
