    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!

    Powerful and versitile converter

    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

    Nagyon masszív, jó felépítés.

    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.

    Very good

    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

    Посылка шла менее месяца. Упаковка супер! Антистатический пакет, моток пупырки и внушительный кусок вспененного полиэтилена. Преобразователь рабочий, на пробу запитал от бп пк. Покупкой крайне доволен!

    Модуль пришёл целый и невридимый, конечно упаковка оставляет желать лучшего, но всё дошло и даже работает.

    good

    Good DC/DC converter to feed many 24 or 28 or 48V electronics devices starting form the 12/24V of a car/truck battery. It wisely comes packed into a anti-static bag.
