Car Humidifier Diffuser Mini USB Cool Mist Air Humidifier Portable, Travelling Size for Office Bedroom Bathroom (Creamy-White)

the humidifier is very easy , but remind just use as humidifier, as it diffuses by cotton stick , so it doesn't recommended to add essential oil. after you refill water then screws on the lid then put it upside down in 2-3 sec to let the cotton stick faster absorb enough water, it will work super well.

I've been looking for a humidifier that can use not only at home but everywhere I go, so I need a product which is travelling size, also with USB port. it can connect power bank or laptop,this humidifier is exactly what I wanted, works great. I'm so happy with my purchase.

Got it December 19th. Quit working December 24th. Now I have to go to the trouble and expense to return it.
