Burned through in record time!

Erlich importance enough, I let myself be led away by the good reviews to buy the same 2 ... An error like Mr. exhibited fast. Unit 1 normally inserted in the car and connected a cooler and a Navi. That was a while (1-2 min.), Then the distribution was already broken. So taken the 2nd distribution and "just" connected the cooler. Again, after 1-2 min. Feierabend. According to the description of the distributor can handle up to 5 amps. He already gets broken at the 4 A that has the cooler is a real tragedy! (PS: Have the cooler can be measured in a workshop, at power 4.2 A and 3.9 A in operating)
