    The package arrived today, at 5th of May (Less then 3 weeks!). Earlier than announced. The Step Up module power supply works very well! I'm happy! Only a small plastic corner broke off during transport. It does not matter. The packaging was unfortunately not padded enough.

    Works ok but minimum input needs to be about 12v not 10. Was only able to test between 10-30v input and 12-50v out and up to about 200w. Efficiency was generally between 87 and 93% over this range. While the smds board appears good, the placement of some the through hole components was a bit sloppy. Most notably the heat sink insulator on one of the power transistors was on upside-down so that transistor metal made contact with the heat sink.

    A marché 2 minutes puis a cramé alors que je tiré juste 58V à 2A... Donc bien moins que 600W annoncés ! Ca a fait foirer mon projet qui m'a déjà coûtait 700€ !!! Génial, je fais comment moi maintenant ??!!!! A ne surtout pas acheter, c'est une perte de temps, d'argent et c'est même dangereux !

    Excelente circuito elevador de tensão e controle de corrente. Este conversor Boost atendeu muito bem o meu sistema de carregamento de baterias de lítio. Ótimo site de componentes e circuitos para aplicação em eletrônica. O tempo de entrega dentro do previsto, bom.

    One screw badly set, after fixing it the module worked correctly. The voltage setting is accurate Module tested to boost from 12- 20V to 43V, 2A

    Only packaged in bubble-wrap - device appeared damaged when arrived but worked OK. Perhaps better packaging would help other customers in the future?
