This pump provides a very good and quick pump to any ball that you are looking for. Not only is it portable but it also has a LCD display for an accurate pressure gauge to assist you with your smart pump. The fact that it is portable is just a plus. It is a rechargable pump. You just simply charge it using the usb cable for about 120 minutes and it should be ready to use. It is great to have in the moments where you just need air in a bike tire or a ball. I love it.
