Rather than having to plug your diffuser straight into the wall, the portable Move Diffuser is cordless and runs on a rechargeable battery. Charging it is simple—you just rest the diffuser on its charging pad for a couple hours. (It’s also able to plug in directly, which can come in handy, too.) To use it, just fill it with water to the internal fill line, drip in however many drops you want of your favorite essential oil, pick a setting (four hours of constant diffusing or eight hours of intermittent diffusing), and set the device wherever you want it today: bathroom, bedroom, kitchen, hallway, whatever. It even fits nicely in a car cup holder. 65ml capacity Rechargeable lithium-ion battery Width: 3.1" x Height: 7.4"
