The utility model is to provide a high-altitude safe escape device which makes escaping people land safely. The upper part of the high-altitude safe escape device is a parachute, and the lower part of the parachute is connected with a half ball which can be charged automatically. When people bail out, the half-ball air-charging airbag at the lower part is opened as the parachute is released. Falling in the airbag, people are more secure, and the air-charging airbag can provide a buffer further when landing on the ground. When landing on the water, the air-charging airbag can act as a raft, helping people to avoid the attack from sharks and prevent people dying from hypothermia due to steeping in water for quite a long time.
