An inflator device which, when attached to a plastic bag, creates a highly efficient air pump for inflating air-inflatable objects, such as boats, air mattresses and inflatable toys. The inflator has a tubular body with a one-way air valve inside of it. One end of the tubular body has a bag attachment fitting with a threaded cap for attaching the device to a plastic bag. The other end has a tapered inflation fitting for inserting into the inflation valve of an inflatable object. To operate the inflator device, the bag attachment fitting is attached to the closed end of a plastic bag and the inflation fitting is inserted into the inflation valve of the object to be inflated. The user fills the plastic bag with air, then closes the end of the bag to trap the air inside. The user presses on the plastic bag with his hands or his body to force the trapped air into the inflatable object. This two-step operation is repeated until the object is fully inflated.
