Our take on the Oneisall 3.5L Cordless Black Stainless Steel Pet Water Fountain with 3PCS Filters

The Oneisall is a 3.5L pet water fountain made of 304 stainless steel with a matte, fingerprint-resistant finish. It runs cordless on a rechargeable battery rated for up to 60 days, so it can sit anywhere without a cable for a pet to chew. A 5-layer filter and three flow modes keep water moving, and the pump is rated under 30dB. It suits cat and small-dog owners who want a steel bowl and no cord, though the filter needs replacing every 2 to 3 weeks, which adds upkeep that simple gravity bowls avoid.

Questions and answers

How long does the battery last on a charge?
Oneisall rates it at up to 60 days of use per charge. Actual runtime depends on the flow mode and how often the pump runs.

Oneisall recommends replacing the filter every 2 to 3 weeks. The standard pack includes 3 filters; the extended pack adds 8 more.
Is it quiet enough for a bedroom?
The pump is rated under 30dB, which is close to a whisper. Most owners would find it quiet enough for a bedroom or living room.
What is the capacity?
It holds 3.5 liters, enough for several cats or a small dog for a day or more depending on how much they drink.
Does it need to stay plugged in?
No. It is cordless and runs on a rechargeable battery, so it can go anywhere without an outlet nearby.
