Review on 🌬️ BOVIS 420ml USB Personal Desk Humidifier: Portable Cordless Ultrasonic Cool Mist for Travel, Home, Office, School & Outdoor - Tiltable, Auto-Off Safety Switch, 7 LED Light Colors by Jeanette Jenson

What I like most about this diffuser is its power supply, which makes it really portable. It charges via a USB-AC connection, so you can take it anywhere and don't have to plug it into an outlet. I had another product from another company that claimed to be portable, but once I started using it, I quickly saw that it operated with a cord and plug and needed to be plugged into an outlet, which its drastically reduced portability. And boy how long does it last, both the reservoir of water and oils and the energy. I tested it at full power and it ran for a few hours before the power went out and the reservoir ran a bit dry. This takes many days. This is the one to buy if you really want portability.
