Me llega el primero y después de 6 días de pruevas con el servicio técnico ( que funciona bien) el aparato de 40amp no carga más de 16a . Deciden mandar otro y este no carga más de 24 en configuración lifepo4 14,4V .. Por lo demás perfecto.. por el precio y lo que da prefiero un victron de 20 Amp. Calienta menos y ocupa la mitad.. O pedir el de 60 haber si se le sacan 30... Que es lo ideal para un alternador de serie

I bought the vevor dc to dc charger 40 amp and this thing suk. On the first week of using it it started smoking very small terminal for the cables also the customer service is suks aswell, just buy something else

bringt nicht die versprochende leistung vevor service schrott

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

I did not receive the item and got no response from the seller

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.

Voilà déjà quelques jours que je me bât pour ce produit, que je ne peux pas installer sur mon véhicule un peut trop de modif à faire vue que je pensais le mettre sur ma voiture. A ce jour je demande le retour du colis et remboursement, vevor me propose 83€ . J'en fais quoi du produit, alors que j'ai voir les mêmes sur Ali Espress et tému . Par contre eu si le convient pas il y étiquette de retour gratuit et le remboursement je c'est j'ai déjà commandé à plusieurs reprises.

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!

I bought this by mistake. I have no use for it not allowed to return it if anyone wants to buy it for half the money let me know. I will never shop here again.
