The mini compressor I bought the tires on the car and on scooters and bicycles inflate. In order for a longer service life in the winter need to avoid flat spots on the tires of my car this season are inflated to 4 bar. This creates the Mannesmann compressor after a few minutes. The temperature that it remains achieved while still within the tolerable. Nevertheless, I still do not begrudge him for a tire a cooling interval. The cable to the cigarette lighter is long enough to loose to get even with larger cars to all 4 tires. From the volume the unit is bearable, everything makes a very solid impression. The connection to the Schrader valve is manufactured by rotation lock - unlike the clamping devices which in some cheap foot pump hang a stable connection where nothing hisses and nothing has to be detained during inflation. What did not work which is under "Frequently Bought Together" recommended Hama AC / DC power supply for the operation of the compressor at 220 volts. Not that the power supply is bad, I have not been ordered, there is simply insufficient for the compressor. Unfortunately, the manufacturer did not specify the power of mini-compressor, otherwise you could have seen directly that does not match. I once measured the current to the compressor during operation draws: 6-7 amps, thus a power consumption of approximately 70 watts. The inrush current can safely go up to 15 amps. Each power supply less than 120 watts of power (ie 10 amps) in my opinion is totally unsuitable for the compressor.
