So much easier than the hand pump I used to use to inflate our air mattress! It inflates a double air mattress in a little over 3 minutes, so very quick. The item is small, nice and compact but don't let the small size fool you, this little thing is quick and powerful! It comes with various different sized adaptors to fit various items and valves on inflatable air beds, pools, balls etc. You also have the option to fix the adaptors in the opposite end of the device to help you deflate items too. Comes also with the USB charger cable and you can easily see how much battery level is remaining by looking at the little lights next to the power button. Charges up quickly and will fully inflate and also deflate our double air mattress 8 times before the battery is flat.
