Our battery operated pet drinking fountains
All of our fountains use a DC pump. A DC pump can be powered by battery or a DC power transformer. So instead of using a power adaptor/transformer, you connect the pump to a battery. The battery can be placed inside a specially made cordless fountain (so no cable is showing outside the fountain) or outside any of our fountains instead of a power transformer (then you’ll have an external box and low voltage cables leading to it from the fountain.)
Choose from a D-cell box or a Li-Ion USB battery.
An external battery solution is for people who don’t have an outlet near the area the fountain is placed, but don’t care about a cable showing on the outside of the fountain.
Having a battery outside of your fountain leaves more room for water inside the fountain. That’s why we offer both internal and external battery solutions.
Fountains with an external battery:
Any of our fountains can be battery operated using an external battery that our pump plugs into.

Fountains with an internal battery compartment (cordless pet fountains):
We can build a fountain with an internal battery compartment, but it takes away from the water holding capacity of the bowl.

We can use D-cell's or USB-batteries to power the pump.
Some samples (cordless pet fountains):
This is how long the pump runs with different battery options:
So how should you handle your batteries?
There is some very solid, consistent advice about getting the most out of your batteries:
The D-cell battery box/holder:
The D-cell battery pack (3 or 4 D-cells, depending on the water pressure you prefer) will keep the fountain running for 140 hours. Rechargeable 10.000mAh NiMH professional D-cells last approx. 3 to 4 days on one charge.
The pump that’s included with our fountains can also be powered by a Li-Ion-USB battery; we supply the adapter cable to be able to connect it to a USB battery, we do not supply any batteries. The USB adapter connects your fountain pump to any USB power supply (eg. USB charger, USB charger battery, computer, USB battery backup, USB power pack etc.).
Li-Ion/polymer (USB) battery:
A portable USB battery charger/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 large capacity.
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. I personally like the Imuto X4 best. If you’re already using a USB to recharge your mobile phone or tablet, we recommend you try it for this application before buying anything new.
(with double USB adapter):
Batteries with problems:
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.
The Rayovac “S-connector” battery:
For this solution, we adapt the cord from the pump to plug into these batteries and provide the battery charger/maintainer. Or you can use your own charger or buy a charger yourself and we can just adapt the cord from the pump to plug into this battery.
The cord from the pump allows you to place the battery (or D-cell box, as the case may be) inside a specially made fountain (so no cable is showing outside the fountain) or outside any of our fountains about 5 feet from it (so you can hide the battery behind furniture, etc.). A special low-voltage extension cord (6 extra feet) is also available.
We also offer a UPS system.
The UPS system:
An "uninterruptible power supply" provides emergency power when the main power fails. A UPS differs from an auxiliary power system in that it provides instantaneous protection from input power interruptions by supplying energy stored in batteries. Our UPS system uses 4 AA size Ni-MH recharchable batteries in a small black box that is permanently installed between the pump and power plug. It can provide up to 7 hours of backup time daily. This system can be handy when you are off grid and your solar system shuts down during the night or if you live in an area with frequent power outages.
