Enjoy the benefits of a birdbath with a beautiful fountain without worrying about your electricity bill with Sunnydaze Decor 2-Tier Pineapple Solar Water Fountain. This double-tier fountain is made of durable， long-lasting polyresin and fiberglass， making it ideal for adding charm to your outdoor spaces. Water flows from the adorable pineapple top. This fountain can run on solar energy or batteries as back-up power. The small， easy-to-install solar panel powers the included pump and recharges the batteries in prime sunlight conditions. On cloudy days or in the evening， you can easily enjoy four hours of fountain life by using the batteries. Once battery power is depleted， the fountain will automatically switch to solar power. If you get tired of the water flow you can turn the fountain off and let the batteries charge—until you and your birdy friends next want to lounge with a relaxing fountain.
