This portable wireless pump is very small yet very powerful. We purchased it to take on vacations to blow up floats or air mattresses when we go camping. The battery on the device seems very large and keeps going after inflating several items. It is also easy to recharge via USB through an outlet or portable battery pack so you can literally take it off the grid. The unit seems sturdy and looks like it will last for quite some time. The sound is also much quieter than some of the other air pumps I have tried. Overall this is a solid air pump that does it's job and is very convenient for inflating floats, balls, mattresses, anything really. Already used it several times without any issues.
