Once you now but this extension cable connects to the Samsung cable to the phone, the charger cable turns off (green LED goes out), no current will be delivered!
First thought the charging cable is now defective.
So the second in the vehicle socket (green) now the second USB extension cord plugged in and ans Galxy Ace.
Green LED goes out and remains so for a while.
It now needs to the original charging cable a few times alone stuck in the car socket (green LED flashes briefly and goes out again immediately), so this again, the function picks up (solid green).
Since the original Samsung cables despite spiral but is too short, is a not navigate the windshield area with me possible because the car sockets are with me in the center console.
The cable (eg by firmly snapping, clicking closure, strap, clip etc.) are not locked to each other but only plugged into each other. At the slightest train on cable or by swinging wähend driving these go then apart again.
Conclusion: The cable not met the required purpose and I therefore went back to the dealer.
Exchange and credit was made without any problems!
