Review on JISULIFE Small Humidifier - USB Rechargeable Ultrasonic 3600mAh Battery Operated Top Fill Humidifier with Dual Mists - 5-12 Work Time - Bedroom, Auto Shut Off - Portable Desk Humidifier for Home Baby by Raquel Ramirez

This humidifier definitely releases moisture into the air, which can be especially beneficial in winter. The instructions are a bit confusing at first, but once you follow them, it should be easy to use. If desired, you can add a drop of essential oil to the water. Be sure to heed the warning that the area around the humidifier will get wet. An interesting feature is that you can charge cell phones and other small devices. I wouldn't recommend charging them while the humidifier is running, but when it's off it's a nice bonus.
