Overview
A cordless, battery-operated pet water fountain holding 2.5 L / 84 oz, with a stainless steel tray where cats and dogs actually drink and a BPA-free ABS housing around it. An AC adapter is included as a backup power source alongside the lithium-ion battery.
Running on battery power rather than a cord is the main design choice here, letting the fountain sit away from an outlet or move outdoors, while the included AC adapter covers situations where battery swaps aren't practical. The drinking tray is stainless steel, though the reservoir and body remain plastic. PETLIBRO lists it for both cats and dogs and backs it with a 24-month warranty.
- 2.5 L / 84 oz capacity
- Battery or AC-powered wireless pump
- Stainless steel drinking tray
- Indoor or outdoor use, 24-month warranty
Who it's for
Fits owners who want fountain placement away from a wall outlet, including outdoor or multi-room setups. Less useful for anyone who'd rather not think about battery levels and just wants a fountain permanently plugged in.
Strengths and trade-offs
Drawn from this product's published specifications.
- Battery or AC power, works away from an outlet
- Stainless steel drinking tray
- Rated for indoor and outdoor use
- Reservoir and housing are plastic, not steel
- 2.5 L capacity is modest for multi-cat households
- Battery-powered pump needs periodic charging or replacement
Performance notes
The wireless pump runs on a lithium-ion battery, with the AC adapter serving as an alternate power source rather than the primary one. The stainless steel tray sits where pets actually drink, while the surrounding housing and reservoir are BPA-free ABS plastic. It's rated for both indoor and outdoor placement.
