Economical but high capacity 12 volt pump suitable for airbeds, inflatable pools, etc. that require large volumes of air at modest pressure. It will also deflate. 
It is driven from a cigarette lighter socket, so you will need access to a vehicle, or a cig lighter socket to battery clips (Cat. TEP505). If you have no 12V power, consider the MWA622
