Hello MOTOR-TALKer! In the title is actually my problem as well as explained, if there would not be a catch. 2 weeks ago I charged with the car USB adapter of Wicked Chili without key in the ignition lock my Samsung battery pack and my Samsung S5 Mini without any problems. Also before everything ran without incidents. Now last Wednesday I had very little battery and had urgently to enter the city. Mobile phone connected to the original Samsung charging cable and nothing happened. Mehrma When I was at home, I pulled off the connected charging cable and put it into my Samsung charging power supply. The S5 Mini was immediately charged. So it’s not because of the two parts. Now the question arises for me, what is the problem then? Is the adapter defective? What about the fuse? Or was it due to the general daily heat? What is not particularly imaginable. h I had a problem again. I also wanted to charge the mobile phone at a portable car hi-fi system (Boombox), which installed a car USB adapter and was supplied directly by the car battery, and also at this time nothing happened. I can’t explain it so properly. Would be very grateful about helpful answers. Greeting Andreas
