I finally found the perfect aromatherapy/humidifier/ USB ports combo for my vehicle!
It has a large 60ml water tank. It has 2 USB ports and the aromatherapy output is controllable and can be shut off if you’d like.
Ive tried a couple different USB ports as well as a couple different diffusers. This is the first one that is a combo of both and has a tank large enough to last a long time.
