I love this air pump. Fills and deflates air mattresses and inflatables really fast. It took less than 5 minutes to completely fill a double-height queen air mattress. It also deflates rapidly and so well that you can fold the mattress flat within minutes. A must-have for campers and my motorhome as it is simple to recharge with its USB power lead. #RankBoosterReview ii. #Sponsored iii. #Pumteck
