I have a very small home. When I invite friends or family over to stay with me, space is limited. I had purchased several air mattresses and an air pump you use by hand. It took forever to air up the mattresses with this pump and you were wore out by the time you were finished.
I finally purchased the Coleman Quick Pump and have been very pleased with the purchase. It has made the task so much easier. It will air up a mattress in about a minute. One of my favorite things about the pump is that it also deflates. It is near impossible to get all the air out by hand. The Quick Pump gets most of the air out which makes it easier to fold and store the mattress.
The Quick Pump also comes with a narrow attachment which is for inflating items such as swimming floats. Although I have not used this product for camping, it would definetly be of good use for a camping trip. I actually found the Quick Pump in the camping section at Wal-Mart.
The only thing I don't like about the pump is that it is a little loud. So if you are inflating a mattress, you will want to do this before others have gone to sleep. Otherwise, you are probably going to wake everyone up.
