【Extra Long Battery Life】Our camping shower pump is equipped with a 6000mAh long-lasting battery, which can work continuously for 120-150 minutes. In addition, its Type-C interface is convenient for charging with mobile devices, such as mobile phone chargers (5V 0.5-2A), mobile power supplies, laptops, or car USB output charging. The interface is equipped with a waterproof silicone cover to ensure safe use. Our portable camping shower uses an upgraded LED display to show power status and water temperature more clearly. Temperature range: 32-140°F (about 1-64°C), allowing you to avoid burns and power outages while enjoying your outdoor adventure. Note: [Our camping shower displays the temperature, but has no heating function]. Our portable shower is equipped with a durable motor and runs quietly, giving you a quiet outdoor shower experience. The shower pump can adjust the high and low water volume, sink into the water, and hold the bucket firmly, easily control the water flow, and save water. 1. First, put the water pump into a bucket filled with water; 2. Wait until the water in the pump bubbles before turning it on; 3. Water will come out during the shower. Note: If you turn on the water pump first and then add water, no water will come out. This will not work correctly.
