The Type C charging port is covered by a silicone waterproof cover, and works with most common 5V USB power sources such as phone chargers, power banks, laptops and car USB ports. The integrated LED display clearly shows remaining power status and real time water temperature ranging from 32 to 140 degrees Fahrenheit, to help users avoid unexpected issues during use. The durable motor runs quietly, the submersible pump can be firmly attached to the bottom of a water bucket, and supports adjustable high and low water flow.
