    In principle, the voltage regulation works, but I get at 12V DC input only a maximum of 9.1V output together (measured with multimeter). The lcd display works from about 4.5V +/- 0.5V. Why the maximum output does not match the input, I can not explain, but I have only rudimentary knowledge of electronics concerns. Maybe this question can be clarified by another buyer, or the shopkeeper?
