I use a battery powered air pump. I have to be home to use it.

I'd like to get the backup battery for my vortech, but haven't yet.

I used to have a Tripp Lite power inverter that could be connected to any amount of battery backup, but never got around to buying the batteries and connecting it. I ended up selling it last fall.

My neighbor has a generator...he's almost always home. So I've just run a cord across the lawn and helped buy him gas in the past.
