    This step-up converter is powerful and versitile. There are two adjustment settings. One for constant voltage and one for constant current. I use this converter on my e-bike together with a 3-phase rectifier that is connected in line with the hub motor cable. This converter is adjusted to 45V output, but with a current limit of 6 Ampére regenerating charging current. The converter delivers 45V out when the input voltage is as low as 7-8 VDC. The constant current works perfectly. It delivers 6 A out when input voltage varies from 12 - 42 Volt. The converter was delivered in a thin plastic bag with some stuffing inside. Small dents on the capacitors, but the converter works fine.

    Part came significantly damaged and broken. Bent heatsink, cracked power connections, crush PCB corners and, most significantly, one of the trimable pots and a resistor had been ripped off the board. Unusable upon delivery. I wouldn't even test it to try and see if it worked for fear of electrocution. I have requested a refund, which Banggood have agreed to, and will be buying another as I need one for a project. I hope the second time around is better!

    Bought it for charging my 13S liion battery from 12V server power supply. It can deliver more power than expected. 35A input is not problem, but I don't want push it too hard, so 30A is better. Even on smaller currents components on top side gets very hot, so I add second fan. Regulation of botton fan is weird. Packaging could be better, because one capacitor is dented and fan is cracked. Effeciency at 30A input is about 84% Very good, very happy with it

    Unit requires mounting and fusing. My application is to use on the output of my solar panel batteries to boost the battery to 13.8 required for my Ham Radio station. My current maximum will be 20A, so I will not over tax this unit, and those 20A pulls will be intermittent up to 3 minutes. Think out your installation. Since mine is emergency communications, I am additionally adding extyernally a bypass circuit in case of failure, 12V Battery straingt through instead of 13.8 is still better than nothing.

    Sajnos a magyarországi kiszállítás megrogyott a nagy csomagáradat miatt. Míg a csomag Kínából rendeléstől számítva 10 nap alatt ideért Budapestre, házhoz szállításig sajnos kereken 1 hónapot kellett várnom.

    It works, I had a small problem with the first shipment, the board arrived broken; Banggood sorted the issue out and the second board arrived well. The quality is good.

    The device came in unprotected, just bagged. It's amazing that it came all the way unharmed. I tested it and it's working beautifully.
