Attempts to recharge the lamp via power adapter or Zigarrettenanzünderkabel (Auto) beat all fail. The charging indicator extinguished after a few seconds. Lt. Manufacturers should be then completed charging. Even several hours loading on the power supply was not successful. The LEDs showed no longer completely extinguished as a very tired light after 2-5 minutes. A replacement also was not successful. The replacement lamp behaved well. I can not recommend the lamp unfortunately.
