This electric air pump maybe small but don't let the size fool you it does pack a big punch it is really powerful. I needed an air pump to use whilst camping and for just blowing my little boys pool and footballs up but didn't want anything to big I saw this and bought it and im so glad I did the item itself can be charged up using a standard micro usb cable and once charged it it really simple to operate, it comes with all attachments neede and is very portable.
