Wanted: Battery backup air pumps

[Pansy-Paws]

I bought the MOPS unit a couple months back, and on Tuesday we had a 1 hour power outage.

It works like a charm ... not sure if I'd call it "silent", but that's the least of my concern when the power is out and keeping the oxygen content up is the prime concern

If I used it on a continual basis, the noise could get on my nerves ...
