900W Digital Control DC-DC Boost Module 0-15A IN 8-60V OUT 10-120V Step-up Converter Power Supply CC/CV LED Display

Works very well technically. Range up to 120 volts was achieved without problems. The only drawback I experienced was that if the input voltage was switched off, it would not remember the set values. I wanted to use this to increase the voltage of a solar panel. But if it had darkened outside, he would lose the set values and had to reset it in the morning. But for the rest, it works 100% well.

If current limits are set incorrectly or not at all, of course, breaks the output voltage but because the module does exactly what it should .... Regarding the heat transfer, I have joined another review and equal heat paste in between .... Helps in any case ..... device works absolutely perfect ... the settings of the display are gigantic ...... (is in the manual ....... easy with search engine KKmoon 900 Watt Digital Boost enter).

So far, everything works without problems A star deduction because of the wrong volt display or setting When I set it, I had a multimeter extra extra and had to find that it is 1.5V difference than what is shown in the setting.

Item is good condition, thanks so much. Well recommended seller

Excellent seller, quick turn around, item as described
