Kundenbewertungen für VEVOR DC-DC Batterieladegerät mit MPPT 350 W 30 A, Ladebooster Dual-Eingang für Solarpanel/Lichtmaschine, Laden für LiFePO4-Bleiakkus, 12 V/24 V-12 V/24 V, für Wohnmobil Notstromversorgung zu Hause

Llego tal y como ponía en la web. Lo he instalado en un autocaravana, de batería a batería funciona bien, desde las placas solares todavía no lo sé, por estar el vehículo en garage.

This thing is awesome works great with my diesel heater.

I bought this DC-DC charger about a month ago. It seems to be good value for the price. I need to charge my LiFePo battery while car camping. Foldable solar panel did not do the trick, I need faster charging. I was specifically looking for 30A MPPT as my battery peak input is 30A. Now I am getting between 20-30A from car and cca 15A from 350W solar panels (measured at non optimal conditions). Charger seems to be working well, although I see some drawbacks. 1) there seems to be no recognition of car running. No ACC wire, no voltage detection. I did tests on external battery and charger was still consuming 20A at 11V source voltage. I added external voltage sensor which turns input on only when alternator running. 2) Solar seems to be preffered over DC in all cases, it means if there is any voltage at all from solar, it runs solar. Result may be that you are getting 0,5A from solar instead of 30A from car battery. I do not care too much as solar is intended mainly when stationary and it will be physically unplugged while driving. Overall reasonable functionality for good price.

Charger seems to work well, no issues yet. My main complaint is that this does not feature an input voltage cut-off, so I had to buy a separate VSR so it wouldn't drain the starting battery into the aux battery 24/7. A feature like that should always be included in this type of device.

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.

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.

I'm not happy with it, i was hoping that it would turn off and on with either an ignition input or voltage when the engine is operating, but it appears you have to use the switch on the unit to turn off and on?
