I have had this product for more than 5 years. I will pull the battery when it dies and replace the battery because I really love this inflator. In addition to blowing up toys, I use it to keep the proper inflation in my tires. It also has a cigarette lighter function that lets me bring my hands free cell phone unit in and charge it over night. I am impressed with the durability and the usefulness. I have used both the Ryobi and Black and Decker equivalents and this is superior. It is advertised here as the Kwik Goal Portable Inflator for soccer enthusiasts but it is way more useful than that. Product Features Inflates up to 180 balls with one charge Cordless with rechargeable 12-volt power pack Plugs into cigarette lighter or household socket Includes pressure gauge, hose and air fitting adaptor Weighs 10 lbs ...
