The Powerplus POWX1700 is a portable air pump. Thanks to the 18-volt battery, it's suitable for small inflating jobs. Think of inflating your bicycle tire, beach ball, or swimming pool. While waiting for your air mattress to inflate, you can lock the start button and go do something else. The attachments and 50cm air hose complete this ready-for-use set, which you can neatly store in the included case.Note: this compressor doesn't fit on a Presta valve. Such a valve is commonly used in the tires of road bikes and touring bikes.
