I bought the Griffin PowerJolt on a recommendation. Initially I was excited because my iPhone has been loaded noticeably faster than with Apple Originalladegeärt. I particularly liked the fact that it is possible to leave the part of the lighter socket and close the lid of the ashtray. The feel was quite good. The joy lasted only three months, because after repeated pulling out - sometimes I needed but then the round socket - the part just fell apart. Now I have the thing lying there in all the items, it is not to build it back together. At least the separation of plastic and metal has become easier when throwing away. I was annoyed to have paid nearly 20 euros for the Griffin. It will probably have been a reason why the price has fallen by more than half. Obviously, many customers have had my or similar negative experiences with it.
