Unfortunately, not quite as it should

I was just very excited when she was there. Small and portable. The charging of the batteries by solar or by the crank wheel went super and Soalar and beautiful sun also quite fast. The light is bright and beautiful to regulate through the two stages as well. Radio is also just does not get it purely many stations. (Ok live quite in the countryside)
The mitglieferte "charging cable" which can be used to charge other devices something is useless, because the plug in the lamp where the cable is plugged in, only to move on and a charging function is equal to zero. Tested with various USB devices. Because the USB cable for charging was indeed doing with.
But we had bought it for this reason to charge over the charging cable via solar something. It has been shown in any of the devices even the slightest charge. Even with full batteries and Soalar simultaneously. That is why there are only two stars. If it had been just about the lights and radio or recharge the batteries, then there would have been 5 stars.
I had bought the lamp some time ago and how do you see this kannn charging function is indicated here only by the term Power Bank and no further information more.
Anyone looking for a bright lamp for camping and a little radio for the what. But should stay away from anyone who wants to use the power bench in the foreground.
