A portable device for inflating an inflatable bag (60) comprises at least one inlet (46), preferably a first and a second inlet (46), for forming a fluid connection to a gas source. Said gas source is attached or attachable to said inlet. The device further comprises an air intake chamber (32) which has an opening allowing atmospheric air to be admitted and an outlet intended to be connected to the bag that is to be inflated. The gas source comprises a first and at least a second gas component, different from said first component. The first component is stored in at least a partially liquid form; preferably, said first component is carbon dioxide. The gas source contains at least more than 10%, preferably more than 30% and most preferably more than 60% of the first component. The second component is gaseous or supercritical at a temperature of 243K and up to a pressure of 200 bar, preferably, the second component has a critical temperature below 243K. |
