PETKIT EVERSWEET MAX 3L Wireless Cat Water Fountain with 5000mAh Battery, App Control & Ultra-Quiet Pump
Product description
Wireless placement without messy cables
If you’ve ever wrestled with trailing leads around the kitchen, this is the kind of cat water fountain that makes day-to-day placement feel a lot easier. The PETKIT EVERSWEET MAX is a wireless, battery-powered fountain designed for cats and dogs, so you can set it where it’s most convenient (for example, near a favourite drinking spot, in a calmer corner, or even outside when you’re doing garden rounds). It’s also a practical angle for smaller UK flats or situations where power sockets are in the wrong place.
No cable running across the floor can be a genuine benefit for peace of mind too, especially with curious pets that like to investigate everything with their teeth. On paper, PETKIT’s approach is all about reducing friction: fewer cables to manage, simpler placement, and a pump that’s built to be safe around water.
That said, it’s not completely hands-off. A battery-operated fountain only works well if you stay on top of charging and refilling like you would with any rechargeable system.
Smart monitoring with the PETKIT app

One of the more compelling parts here is the app-controlled monitoring. Using the PETKIT App, you can track drinking habits 24/7 and view real-time drinking records, including frequency and duration. There are also weekly and monthly hydration insights, plus app reminders aimed at refills and filter changes—useful if you’re busy, often out, or simply like having a better picture of routine.
If your goal is “more than just a bowl that looks nice”, this is where it leans ahead. It turns a basic hydration setup into something closer to light, behavioural monitoring.
Worth noting: the fountain supports 2.4GHz Wi‑Fi networks (it’s stated as a requirement), so if your home doesn’t use that band, you’ll want to check before you buy.
Battery life and wireless operation in the real world


The EVERSWEET MAX runs on a rechargeable 5,000mAh battery unit, with up to 83 days of standby time mentioned in the product info. That’s a decent window for weekend trips, day-to-day life, and even power cuts—there’s also an emergency storage capacity of 130ml described to help keep your cat going briefly.

The battery unit is detachable and designed to be removed and recharged more easily than a fully hard-wired setup. The limitation is fairly straightforward: for uninterrupted operation, you’ll need to plan charging as part of your routine rather than simply plugging it in and forgetting it.
A practical example: if you’re leaving for two or three days, you can place the fountain where you normally keep it without thinking about socket access—then rely on the battery until you’re back to top up.
Quiet pump, safer design, and everyday confidence
PETKIT states the pump is ultra-quiet, aiming to avoid disturbing nights for both you and your pet. It’s also described as a wireless pump design intended to prevent electrical components from coming into contact with water. That’s a reassuring design direction, particularly if you’ve previously had worries about water + electrics.
The fountain also includes an automatic stop when the water level is low, which is meant to improve safety.

Filtration that focuses on cleaner, fresher water
This model uses a quadruple filtration system: sponge, activated carbon, a high-density cotton layer, and a sponge filter. The intent is to filter impurities, remove odours, soften the water, and help extend pump life—so it’s not only about making water flow, but about keeping it fresher between refills.
Whether that level of filtration matters to you depends on your household. If you have a water source that can smell a bit “off” after sitting, filtration-focused fountains are often the more satisfying experience. If your tap water is already pretty neutral, the difference may be less obvious day-to-day.


Hydration modes and how to choose the right one
The EVERSWEET MAX offers 3 hydration modes:

- Smart Mode (intermittent flow to mimic natural streams)
- Normal Mode (continuous flow)
- Battery Mode (wireless operation for portability)
On paper, the mode selection is a neat way to match your cat’s drinking preferences. Some cats prefer the “moving but not constant” feel, while others are happy with steady streams.
PETKIT also mentions that the setup is intended to encourage more drinking and support kidney health. It’s a common framing for pet hydration products, but it’s still worth keeping expectations realistic: a fountain can help with hydration habits, yet it’s not a medical treatment.
Where it shines—and where you might want to skip it
This is the kind of cordless cat water fountain that makes sense if:

- You want flexible placement without dealing with cables across your home
- You’d like app-based monitoring of drinking frequency and duration
- Quiet operation matters, especially if your cat drinks at night
- You prefer a filtration system designed to reduce odours and impurities
It may not be the best match if:


- You’re likely to forget charging, refilling, or filter changes (battery systems still need routine)
- You can’t/won’t meet the 2.4GHz Wi‑Fi requirement for app features
- Your priority is purely “set and forget” via mains power (cordless is convenient, but it does add a maintenance step)
Mini FAQ
FAQ: Common questions before buying

Will it work if I don’t have a 2.4GHz Wi‑Fi network? The app-control feature is stated as supporting 2.4GHz Wi‑Fi networks only, so it’s worth checking that requirement first.
Is the fountain only for cats? The product is described as a wireless water fountain for cats and dogs.
How does it handle low water? The pump is described as automatically stopping when the water level is low.
Does it include an emergency water reserve? PETKIT mentions a 130ml emergency storage capacity for short power outages.
Final verdict
It’s a strong pick if you want a wireless, ultra-quiet fountain with app monitoring and a filtration system aimed at keeping water fresher—especially if placement and cable management are recurring annoyances in your home. Just be honest about the trade-off: you’re signing up for a little charging and upkeep, and the app side needs 2.4GHz Wi‑Fi. If you’re comfortable with that routine, the EVERSWEET MAX is the sort of upgrade that can make daily hydration feel noticeably more practical.
