I am happy with the units, all working, despite the small chances, based on the "law of total probability", they arrived without damage, small eggs and bricks in the same bag without protection is something very peculiar, the assembly of the components is not 100% aligned . The output voltage remained constant even with extreme variation in the input voltage, below 5v is too extreme, without load or with varying loads, in multimeters aneng and hikari the voltage remained stable, varying only at the voltage input, according to load # Estou feliz com as unidades, todas funcionando, apesar das pequenas chances, baseado na "lei da probabilidade total", chegaram sem danos, pequenos ovos e tijolos na mesma sacola sem proteção é algo muito peculiar, a montagem dos componentes não é 100% alinhada. A tensão de saída se manteve constante mesmo com variação extrema na tensão de entrada, abaixo de 5v é extremo demais, sem carga ou com cargas variadas, nos multimetros aneng e hikari a tensão permaneceu estável, variando apenas na entrada de tensão, de acordo com a carga.
In general, it is good, but if the input voltage drops below 3.5V, the output voltage will be triggered up to the maximum output, around 30V.
Be careful with that "detail" !!!
