Give 24/7 non-stop running water to keep your pets hydrated, happy and healthy with PetLibro's Dockstream Battery-Operated Pet Fountain. Cordless functionality but you can also plug it into the wall for constant streaming. I found that worked better in my household. Used less than a year. Well-maintained, clean, fully functioning. Non-smoking household. I’ll include two replacement filters with the unit. Two identical units available (10% discount for both). Specs below. • Stainless steel bowl • Long battery-operated life Powered by 5,000mAh built-in rechargeable battery. • Cordless drinking The wireless pump and charging base are free from external wires to eliminate any charge from the water and allow pets to drink comfortably. • Dual watering modes Radar induction drinking mode that activates flow within 31 inches, preserving power. Or select conntinuous flow mode for 24/7 flow when connected to a power supply. Set up as a free-falling stream or bubble fountain.
