Can me the pros reviewers only anschleißen. The part has at last the necessary power to start a 2.5 TDI. While even despite the steep price probably still "only" high-end for consumers, the real pro-portions (probably start at around 600) one can not so easily ran. This one can still make light, has a 12-volt socket (cigarette lighter). But fortunately not the bells and whistles such as built-in compressor, etc. There are two internal batteries (standard !!!) that can be changed, and it can also be 24 volts (as I would sometimes like to present when the start a truck diesel: - )) Conclusion, who lives in a winter Pregnant region, like to anlässt the light and do not always want to wait the mandatory hour to the ADAC, the part should increase. For small gasoline Zun's probably half as expensive parts from the hardware store .......
