    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.

    Well packaged, received in good condition and excellent delivery time (10 calendar days from order). For the past year or two, my projects have used power distribution from a central 12V solar system to local micro-controllers which use buck converters to drop the voltage down to the target level. Recently, I have been experimenting with using a higher distribution voltage (at least 24V for better wiring efficiency. I bought this unit as part of that project. My idea is to boost the voltage at source to 24V and replace the wiring project-by-project, and then upgrade the solar to 24V. Of course, I might decide to use a higher voltage, like 30V, 36V or 48V. This unit will let me experiment with all those options. The unit seems well-build and robust, so I'm feeling confident about the project, even though it's early days.

    Device is starting from 12.4V Minimal constant current mode is ~1A MOSFET have no termalpad Inductor was not fully soldered Maybe it is only on my devices but I have to share this information.

    This converter is very valid and reliable, I bought a number, the first one has been working for 2 years without giving the slightest disservice. In my case they are used with an output of 36v 5 A and I proceeded to increase the heat sink as the original one with a power of about 200W continuous heats up too much.If you keep the original one you need a small fan. Great material I recommend the purchase. Personal note: in case of failure the repair material is easily purchased.

    The form has been delivered in full compliance with the times notified, has been crafted and has not been damaged in the transport. It'a very valid product for various uses: in my case it is used on a solar panel, on 2 beaters for olives.
