Comprado por recomendacion de un amigo, el peso se lleva bien, pediria el mismo otra vez.

No esperaba mucho a este precio, buen compra en general.

Faltaba algo asi en casa, facil de entender, manual ni hecho falta, se queda conmigo, lo volveria a comprar.

Bem embalado, chegou rápido e parece tudo bem. Ainda não o experimentei mas brevemente, volto a comentar.

Works fine

Ik had eerst een 20 A dc dc lader van vevor. Die laadde maar 10,5 A. Deze had wel een d+ aansluiting zodat die automatisch stopte met laden als het contact ontstond. Nu de 30 A gekocht. Deze laadt 22A. Het enigste probleem is dat die niet stopt met laden als het contact uitstaat. Als de lader vergeet uit te zetten trekt die heel je startaccu leeg. Er zit geen d+ aansluiting op. Alles is aangesloten volgens schema en de bus is een Renault trafic. Is hier een oplossing voor?

Well... I thought I had bought a nice product and was very happy with it at first, however, upon Realizing that the instructions that came with it were a little confusing and didn't answer all the questions I had about how to operate the unit , I decided to contact customer service and ask a question. They had me give them my information, said they would help me and then continued to ignore me. And I never did get an answer to my question. This leads me to believe that there customer service is a joke. Otherwise , I would have given this product to higher rating.

Ich war durch die, schon abgegebenen Rezensionen, vorgewarnt. Von einigen Nutzern kam die Klage, der Booster entlädt die Starterbatterie. Nach dem Anschließen des Boosters, fing dieser auch gleich an zu laden. Da ich mir im Vorfeld schon eine Anlage für eine Powerstation in meinem Wohnmobil installiert hatte, hatte ich ein Trennrelais schon an Bord. Dieses habe ich dem Booster nun vorgeschaltet, es schaltet über D+. Funktioniert nun alles, aber richtig ist das nicht, auch wenn das Teil nur die Hälfte von einem Victron kostet. Zumal nun die Rückladefunktion blockiert ist. Wie es dann im Dauereinsatz funktioniert, wird sich zeigen. Es sieht aber auf jeden Fall wertig aus. Auch mit der Lieferung bin ich sehr zufrieden.

Straight up garbage! It does not shut off and save the battery on the vehicle automatically, the dip switch settings are bogus I had to solder out my dip switches! What a waste of time and money! With my lithium iron phosphate battery sometimes it'll charge up to 13.1 volts sometimes it won't go past 12.5, according to Specs it's supposed to go to 14.4 volts. The only thing that's good about it is I can pop the hood, turn the breaker on, and charge while I'm driving so on days when there's no sun I can still keep my fridge running in my camper van, it will suffice for now until I get my victron set up going instead

Unit failed after 70~ days. It is trying to output current via the small xt60 solar plug and discharging both the cranking and the auxiliary batteries at the same time. This has been tested and confirmed with a clamp meter and temperature gun, the solar panel gets ROASTING hot when plugged into the charger at night in the dark. The dip switches also no longer switch between voltages, the unit is stuck and refuses to charge from the alternator at all. Customer service is refusing a refund after providing video evidence of the fault saying it is perfectly normal for the charger to dump current across the solar panel and flatten your batteries instead of charging them.
