Two problems I had nevertheless: 1) I wanted to connect a device that has an exceptionally thick plug. When trying this reinzukriegen in one of the sockets, I have also slightly turned it back and forth. An error! Because that has become the "metal tube" of female rotated, whereupon the contact inside the adapter is demolished. A female was therefore at the very beginning of my journey dead. (This can be but with very little skill later soldering. If you're at it, you should then attach the metal tubes equal with some super glue so the housing that they no longer can rotate.)
2.) I wanted to connect a cooler to it, but despite the fact should have get there with the 70 W, while the fuse is blown. Fortunately, however, can also easily be replaced: simply the small metal contact on the plug, which comes into the cigarette lighter, unscrew and install a new fuse.
Conclusion: Plug only * just * insert and remove the adapter - not rotate / wiggle! And better yet a few watts remain under the rated power ... If one considers that the adapter is great, and I do not want to miss him in the car!
