Deceives the first good impression

I bought two of these devices, one for me and one for my father. The promised start output of 1,000 A was the main reason to buy. We have both cars with a diesel engine. My past experience proved that at temperatures below zero and largely discharged starter battery of a diesel vehicle with a weak start of the Jump Start Device misslingt.Die APA devices initially made a good-quality impression. The weight started off with a potent, built Bleiakku (AGM). Apparently unfortunately the device but have a built design flaw that the promised max. Off power of 1,000 A allows only once or not at all. One device applied after several days Laden just a measured take-off power of 200 A. The second unit took her as a long charging time actually once the promised 1,000 A-off power to the power measurement. After another several days Charging time performance was after the later ordered unit of my father refused, remeasured on my device. Lo and behold, the unit brought now just less than 200 A starting power. Why I was ever so suspicious and checked the performance of the equipment measurement. The widely divergent assessments in the customer reviews have alluded to the fact that it could perhaps provide quality defects in the production of equipment or individual components may be insufficiently dimensioned. Here the presumably Chinese manufacturers may need to be made to revise the design of these pleasing affordable devices.
