    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.

    DC to DC voltage booster usable up to 600W load but carefully, just with a bigger heatsink because the original is insufficient for such load. It can handle input from 10-60 Volts by outputting 12-80V but higher the difference is , higher is also a thermal loose. It has a build in fuse which is very good to be protected such way. I use it as a LED chip 100W x 4 driver from 24V To 38V and 6Amps per chip output.

    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.

    Good converter, make easy to charge the battery, or drive load with different voltage. Quality board & components!

    These are good little boost converters. Mine arrived quickly, and well packaged. Would buy again. Good seller.

    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?
