    Apart from the fact that the device comes without any protection for transportation it is almost a miracle to arrive here in Brazil whole met my need well.

    The product ran out quite early. Wrapped in a curled bubble band and put in a plastic envelope.Due to the weight of the product, this is insufficient. The 1000 microF 63 V electrolyte is damaged. It's got a minus outlet and the circuit board's damaged. The product is unusable. My past problems have always been related to poor product packaging. You want me to buy a new product?

    Velice dobře provedený DC-DC zdroj se zvyšujícím napětím. Vyzkoušeno při vstupním napětím 12V s poklesem na 10V. Na výstupu nastaveno 14.5V s odběrem proudu 5A. Tento produkt splnil moje očekávání. Napětí na výstupu si drží svou hodnotu i při změně proudové zátěže. Proudové omezení vyzkoušeno při výstupním napětím 24-50V. Vše OK. S produktem jsem spokojen.

    I´ve not tested it yet. It seems good stuff and well mounted. I hope it works as expected.

    working properly but i was disappointed with the packaging, it should be packed in a box to avoid damage. the heatsink is bent, i just straightened it up. but it's working great.
