This small diffuser packs a lot of technology into one device. Its high portability makes it perfect for those on the go.  Need to hit your face mask with a whiff of aroma, give it a short burst.  Want some refreshing aroma when on the road, use it in the vent of the car.  Sitting at a desk, put it on the wall next to you.  Camping, use it on socks and clothing to repel insects or turn it on when sitting down for a snack.  Eating outdoors, keep it on the table.  It has a built in rechargeable lithium battery and runs for about 20 hours on one charge.  Recharge using the included USB cable takes about 3.5 hours.

It comes with six bottles that hold 4 ml. of diluted essential oil.  You can use your favorite carrier oil to reduce the intensity of the aroma.  You can also dilute the oils with glycerin, witch hazel, vinegar, wine, or a vodka.  Experiment with different blends for different occasions.  You want to disinfect a work space, use something more antimicrobial.  Outdoors, use insect repelling oils.  Need to relax, try something soothing.  Feeling sleepy but have to stay awake a bit longer, use a refreshing oil.

These diffusers have two options.  The car model attaches to the back of the diffuser to mount on a vent and the other model is for mounting on a flat surface.  Neither attachment is necessary when carrying in a pocket, handbag, or backpack nor when used simply standing upright.
