Although we mostly looked at electric pumps, hand pumps do have some advantages. For one, they’re far more economical. Secondly, they don’t require power and thus can be used outdoors and far away from power sources- meaning you can take them camping, if you should want to have a birthday party in the woods! Lastly, they can make great party favors, since their low cost and power-free functionality means you can buy a number of them and hand them out to party guests so that they can help inflate balloons if they want as well.
