The first device worked exactly 1x. The next day I asked randomly fixed (random because: permanently installed in the bed box), that the thing was no more signs of life. So complained ... the replacement unit was afloat at home.
Unpacked unit no. 2 and immediately inserted into the power ... Some went to LEDs and erlischten after 2-3 seconds, then on again, and so on. I thought maybe the white part not what it should do so quickly yet connected to the battery and turned on. The response was unchanged. On, off, on, off ... At every turn you could a faint crackle / hum from the case heard.
FYI: The battery is charged brand new and fully.
In a third experiment, I will not be a. Return to sender!

Addendum:
I have chosen as a replacement device for this garbage, for a small Ctek charger. The device is now installed around a 3/4 year fixed and actually permanently on power. What can I say? -Perfect! The battery is always full. So be hell!
This is where clearly the rule, who buys cheap, buys 2x.
