Four-level adjustable discharge timing: 0.3s, 0.8s, 1.5s, and 2s. You can freely choose the foam length to suit your needs. The automatic foam soap dispenser uses a new infrared sensor chip to detect a hand within 2.75 inches, and foam is released automatically. Smart and engaging design: Encourages children to wash hands, stay hygienic, and be healthier through interactive use. Compatible with a range of soaps: Works with dish soap, shower gel, shampoo, hand sanitizer, or facial cleanser. Foam-type water-based hand sanitizers and facial cleansers can be used directly. Thick hand sanitizers and water can be diluted 1:3 before use. A visible reservoir lets you gauge the amount of soap remaining. Type-C charging: Built-in 500 mAh battery with separate indicators for battery level and gear position. USB-C fast charging makes charging convenient, and a full charge lasts about 90 days. Compared to battery-powered dispensers, this reduces battery waste and lowers long-term costs. IPX5 water resistant: Made from high quality ABS and PETG with splash protection. The IPX5 design helps prevent soap or water from damaging the dispenser. A silicone waterproof plug on the charging port allows the body to be washed with water, and it will continue to operate even if children splash it. Flexible installation options: Can be placed on a countertop or mounted on a wall to save space. Ideal for kitchens, bathrooms, toilets, offices, hospitals, hotels, homes, schools, restaurants, and more. A practical Christmas gift for parents, partners, and friends.
