I have just received the boost converter. Worked fine at first glance. Factory adjustment output was at ~22V. PROs: - simple project, low number of components; - price :) - able to boost voltage up and down in its range; - nicely assembled; CONs: Here I wish to say that a number of improvements can be done, not that the product is of a bad quality. IMHO the module deserves being purchased. I would name this not really CONs, but FEEDBACKs for an optimisation of the product. - the output voltage from factory is too high. If a noob just connects the output to a device needing, let's say, 12V, he will burn his device. The factory voltage should be set to its minimum. - I have bought 11 pieces and on some, the pot regulating the voltage was not inserted into the holes properly. I recommend resoldering the potentiometer. - The module could work better with minor modifications. See http://www.360customs.de/en/2014/05/103050100w-led-applikation-treiber/

Regolatore di tensione fino a 150 watt...per potenziare , esempio, un pannello solare e portare i watt alla batteria. Oppure per potenziare una batteria aumentando i watt per sostenere un carico elettrico in misura uguale o pari fino ai watt dichiarati. Criticità: il pacchetto non è stato avvolto da prodotti per ammortizzare gli urti, ma semplicemente avvolto in una bustina
