Had device while camping here and loved it. Has the air mattress (190 x 190 x 25 cm) bulging in 4 minutes, even with a large safety valve. Only in air mattresses with small safety valve the essay has not optimal fit, that he was a little too short so that the safety valve could be opened so. If the safety valve but is compressed, these air mattress can be inflated only slightly inconvenient. Otherwise, really great and enough of the performance. However, a connection cable for vehicle (cigarette lighter 12V), as described in a previous judgment is not present. For at home or at campsites on which a power supply is available, I would recommend this unit highly enough.
