This air pump is great. It comes with an instructions guide as well as four different nozzles for a perfect fit. I utilized this portable pump to inflate an air mattress, which was a full size, and it worked well. It only took about 2-5mins to have it completely aired up. I also used this pump to blow some leaves around outside and it has some good power to it. The light that is on the pumpis pretty bright and can be used at night or when you're out camping. This is a great tool to be used indoors and outdoors if needed. I would definitely recommend having one of these portable air pumps for multiple uses.
