Never buy it, very difficult to install (M5 bolts))) and it will not charge. bad quality

Montato a regola d'arte da un professionista con esperienza trentennale il caricatore non funziona. Dopo vari confronti con l'assistenza non hanno voluto cambiare l'oggetto e nemmeno hanno proposto un rimborso. Ne ho comprato un'altro di altra marca che ha funzionato immediatamente. Hanno perso un buon cliente. Non comprerò più nulla da vevor.

Ostin 60A mallin, mutta lataa vain 20A vaikka akkujännite on 12.6V ja dippiasetus on 14.6V

I did reverse the polarity of the output terminal and the device was ruined. I replaced the inside fuse and device keeps blowing ints internal 20amp fuses.

It die after about few of working, very unreliable.

Purchased 2 40 amp inverters to charge a 280AH lithium battery in two different service trucks. Neither truck will charge the lithium battery. Hooked up as instructed, it turns on but no output voltage and lithium batteries and batteries goes dead. I have bypass the inverters in both trucks until I can get them to work. No fault light is on just the green on light. I have the dip switches set for 14.6 volts passed on the lithium battery instructions. I have messaged Vevor for assistance and have only received a pdf file of the manual that I already have that came with it. I sure would like to talk with someone but in the messaged it said that they didn't have that as an option for assistance. Now what. Return them? Please help!

Ik heb de 40 A uitvoering, maar het is een zwakke acculader, hij komt nooit boven de 14 volt, ik heb spijt van mijn aankoop en raad hem af

There is no effing quality control here, the litle screw too hold in the d+ ignition wire sucks and doesnt work for holding in the wire that is required for it to run, so it sucks and is useless and i want my stupid money back. I just spent 2 hours installing it for it to be bullcrap

I wanted this product to charge lithium battery from 12v source in RV. 12 in 14.4v/14.6v output however this was just 12v in 12v output. The terminals are tiny and would not take a 4 or 6aw wire gauge, teh recommended for charging Lithium. When requesting a return, it took many emails and over a week to resolve. Would I try Vevor again, probably, just not this item.

apres mise en place le produit ne c'est jamais mis a fonctionner . notice pas tres claire.
