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 rechergeable Li-Ion USB battery (power pack).
|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
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 Ziplock bag since these batteries don't
like getting wet.
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 runtime with it than the others. The RavPower RP-PB41 has the longest runtime 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 automaticly.
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 have been made in 2016/2017. Since then models have changed, are
discontinued and 100reds of new models are on the market.

Continuous runtimes with pump model JT-180 are approx. 20% shorter.

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 runtime before having to recharge, but you’ll need a total of 4 batteries.
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. Don’t regularly discharge your rechargeable alcaline or NiMH batteries completely. Complete discharge will shorten their lifespan. For more info's about rechargeable alcaline batteries see: Wikipedia
5. 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.
6. 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 batterie(s) be enclosed in a water tight ziplock bag before putting them inside the compartment. Likewise, 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.
