Query: Takes too long!

I also bought this at Lowe's and not Amazon. I wish I would have read the reviews on here before purchasing as I would have saved myself some money.I bought this station primarily for inflating air mattresses when camping. The AC/DC choice was perfect. Unfortunately it takes about 20 mins to blow up a standard size mattress.As others have mentioned, the device is very loud. Having to listen to that thing for 20mins minimum in a camp ground or house is taxing on the nerves. If your use is for air mattress, then I suggest getting the battery operated ones that are sold in the camping gear section.If you are only doing bike tires, it's tolerable. Slow, but tolerable.
