Esta genia y carga rápido

Absolutly ok value for the cost. Little bit to loud when the fan is working. Easy to install and use. Great feature with the reverse charging of the vehicles battery.

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

Super

Works good. I especially like being able to reverse the charging. The i can charge the chassis battery's with house batterys iif I leave lights on and run down the battery's. It would be better if I could remotely turn it on and off. That's the only thing I would change

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.

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.
