Unfortunately, the compressor is a little weak in the chest and also extremely loud. The "first fill" I have made at the gas station, the filling has the 2nd ditch almost 10min. lasted (195 / 55R16 tires). But since one fortunately not every day has broken down, it is perfectly adequate. However, I would want to inflate any air mattress or swimming pool so.
CONCLUSION: Those who have no spare tire and only a hole in the tire must not wait on the roadside ditch on the ADAC but ideally at home or at the hotel thanks to the repair kit.
