Tired as many seek an inflator in the resort, with not necessarily reliable messures (between the material and the tires warm +/-), I looked for a portable pump. The reviews on this product + name (Mannesman) took away my decision. Unpacking, beautiful finish: the compressor is packed in a bag (apparently robust) black nylon. Several tips (ball, biking, etc ...) are provided. The build quality seems great. The power supply cable length 'allows PB without reaching the rear wheels on a big car (I have a Terrano II). Rapid inflation rate: 0.4 bars I added to each tire in less than two minutes. My Harley is passed then at the same speed! The tip for screwing valve is quality, and causes no leakage at the connection. Only problem: it would take a 220/12 V adapter (cigarette lighter). The battery of a large diesel engine running, supports carefree bulking session, but what would a small car? That's the only reason I did not put 5 *, otherwise deserved
