Power failure batteries?

[plancton]

Which products are there in the market for power failures?. Like a battery or something where everything or just the pumps are connected and once there´s a power failure, the battery starts working automatically. Hands free.

For very short term outages you can use UPS battery backups like they use for computers.
(UPS)" "Uninterruptible power supply"

There are a wide variety available and I'm far from being an expert but that should help get you pointed in the right direction.

I just read about them at the office depot site and they all say you´re covered for like 30 mins. That is worthless in my opinion. I would like to keep 2 koralias running for at least 10 hours.

I heard about portable power supply. Those units are about $100 and are supposed to be more used by acuarists. I just don´t know how many hours they can give to two koralias. Any experience with them?.

And there´s also
gasoline generators and stuff, are just way to big if you´re only intending to have 2 small pumps running.

UPS's are meant to run computers for 30mins+ which are usually 600+ watts. You're powerheads use a lot less power to run and would run a lot longer than a pc using a ups. Also my old job used UPS's in our warehouses and we recieved a lot that batteries died in the UPS. UPS's are cheap and effecient but most people use whole house generators like generarc and keep there whole home powered during a powerloss. They do cost 2000-4000 or so but would keep your whole home powered.

You can build a UPS yourself that will use several marine type batteries that will run the powerheads and heaters for many hours but it can get expensive, I looked into it a few years back and found it was going to cost me about $800.
I went years without a power outage and have always kept a small gas generator on hand if it's needed, The generator cost me $300 and I can run it for days at a time.
