If not used for an extended period, shake well before next use. Strong Performance: The unit features a built-in battery with excellent sealing to prevent water damage or corrosion. No battery replacement is required. It charges in just 1.5 hours, providing up to 90 days of continuous use and over 108 days in standby mode. Consistent Liquid Output: Equipped with a high-efficiency motor, the dispenser delivers stable and quick foam output within 0.25 seconds, minimizing clogs. Foam soap is recommended for best results.

After dispensing foam, wait until the foam fully dispenses before removing your hand to prevent overflow and potential blockage.
