Here’s another fantastic, multifunctional product that has been specially designed for car use. This 3-in-1 diffuser enables you to fill your environment with your favorite essential oils, and it certainly won’t get in the way as it has a special ‘cup’ design that fits into your vehicle cup holder. What many people don’t realize is that cars can become quiet dry and dry air has a terrible effect on skin, lungs and eyes. This car oil diffuser works as a humidifier as well as a diffuser and features an intelligent ‘off’ switch so it will automatically turn itself off when the water runs below the low-water line. This product comes with two USB charging ports and one car charger socket so it performs its third job as a charging port in your vehicle.
