Air Pack protects breakable things. The air-filled pack fills the space in the luggage and secures objects in place, while the injected air absorbs external shock.
Travel carriers, in general, are not built with a safe space to keep delicate or breakable articles such as IT devices and cameras. The risk of damage is even higher if there is a lot of the free space in the bag, and articles in the bag end up in a mixed and messy state.
Air Pack pumps air into a pack that fills the inner space of the travel carrier. It acts as a buffer and protects them from the external shock, thus reducing the risk of damage.
