All of our water fountains for cats and dogs can be powered by battery or a low voltage power adapter. We've offered battery pet fountains for over 10 years. You can battery power your pet fountain or plug it into a nearby outlet; it's up to you. The pumps we use are special low power consumption DC pumps, known for their performance and reliability; they run a long time before it's necessary to recharge/exchange batteries.
The battery can be placed:
- inside a cordless fountain (so no cable is showing outside the fountain),
- inside a detached ceramic battery compartment standing directly behind your "regular" round Ebi pet drinking fountain,
- or outside any of our fountains instead of a power transformer (then you’ll have an external box with low voltage cables leading to the fountain).You can choose between a D-cell box/holder or a rechargeable Li-Ion USB battery (power pack). Always keep your battery dry!
|AA-Cell||3 to 4||alkaline||30 hours||no|
|D-Cell||4x10.000mAh||NiMH||up to 3 days||yes|
|D-Cell||4 or 8||alkaline||up to 12 days||no|
|Li-Ion USB||5 Volt||Li-Ion||up to 10 days
A portable USB battery/USB power pack (usually used to recharge your
cell phone when you are off grid) can be used to power the fountain
pump. They are lightweight and have a large capacity. Be sure to pack
the battery into a quality Ziploc-type bag since these batteries should
not under any circumstances get wet.
We do not recommend any specific battery or brand, but we’ve tested several different USB batteries (see table below.) The Anker is supposed to be the best quality with regard to lifespan, but we didn’t get any significantly better run time with it than the others. The RavPower RP-PB41 has the longest run time as a single battery but can not be used as a tandem battery (two batteries parallel) since the RavPower RP-PB41 doesn't take over automatically. If you’re already using a USB battery to recharge your mobile phone or tablet, we recommend you try it for this application before buying anything new.
These tests were run in 2016/2017. Since then models have changed, been discontinued and hundreds of new models have come on the market.

As the table shows, these will need to be recharged approx. every 3 to 5 days. We suggest ordering 2 batteries, so that one can be in use while the other is charging. We have constructed a “double adapter cable” that allows 2 batteries to power the fountain in tandem – this will give you double the run time before having to recharge, but you’ll need a total of 4 batteries.
Whilst RavPower has a number of models we can recommend, here are the top three picks for pass through charging power banks . They’re all incredibly powerful and should be capable of seeing you through you pass through charging needs.
This incredible charger is packed with all the latest tech needed. 45W of pure power couples with 20100mAh for a stupendous battery capacity and delivery. What’s more, Power Delivery enables fast charging.
Once again featuring Power Delivery technology, this charger packs a punch. It has a whopping 26800mAh and up to 30W. The advanced iSmart technology keeps you protected from overcharging, short-circuiting, and a host of other potential downfalls that regular power banks face.
Gigantic Capacity: 32000mAh internal battery capacity provides up a week of power. Its amazing what devices with pass through charging are capable of! We're testing this battery at the moment.
There is some very solid, consistent advice about getting the most out
of your batteries:
1. Be prepared to replace them, eventually. Rechargeable batteries don’t last forever, and through time and use they will stop working. Thank them for saving you money, recycle them, and move on.
2. Buy a good charger. You don’t have to spend a fortune on the best charger available, but make sure you get a “smart” charger, one that electronically monitors the recharge process and prevents overcharging. Not only is it better for the batteries, it will use less power than cheap chargers, which often rely on a simple timer mechanism.
3. Remove the batteries when the recharge is complete. Unnecessary time on the charger means more “trickle” power is used to keep them charged—so more wear and tear and more wasted power.
4. Store your batteries fully loaded (never empty!) at room temperature in a dry location. Excessive heat can definitely damage your batteries and cause them to lose charge faster.
5. Every battery should be
protected from water, but Li-Ion batteries (USBs) are
particularly sensitive to water damage because they have electronics
inside. We craft our internal battery compartments to keep the batteries
dry but there is always the possibility of condensation forming, so it
is imperative that the battery(ies)
be enclosed in a high quality water tight Ziploc-type bag before putting
them inside the compartment. And of course, if your cat has the
propensity to play in the water, external batteries need to be protected
as well. You have about 7 feet of cord available, so put them in a
higher place, a nearby drawer or a waterproof container.
6. It's important to follow the safety guidelines that accompany your batteries!
