Automatic induction design enables an efficient hand cleaning and eliminates cross contamination.The tank has a capacity of 350ml.It's designed to spray mist, so it's recommended that you fill the tank with liquid hand sanitizer, like alcohol.With a built-in battery of 1200mA, it can work continuously for 140h after fully charged.It's great to have it on bathroom sinks, or kitchen countertop.
