Easy install and so far it looks like it’s doing what it’s supposed to do. Using it as a LifePo4 battery charger when we travel.

Fungerar som förväntat, installerad i en husbil med smart generator och lithium batteri kopplad via elektro blocket. Snabb leverans och enkel o lättförståd instruktionsbok medföljer.

Works really well. Easy to install and runs just fine. Like that it has a fan for cooling as to not have it throttle during hot summer days.

Inga bekymmer gör det den ska enligt beskrivningen

Schöne Ausführung.Die Bedienungsanleitung könnte besser sein . Sonst alles Gut.

Egyszerűen beépíthető. Tudja az igért adatokat. Csendben dolgozik . A legkisebb teljesítményű koncertet választottam , gondolva az autó generátorára is .

Le produit n'est pas compatible avec mon installation T Max (problème sur entrée et sortie pour les batteries) J'attends le retour de l'article qui est dans son emballage d'origine et neuf (non monté)

Hello, The charger is receiving 14 V at the input. The D+ cable is also receiving 14 V when the engine is running. However, there is 0 V at the output. I have checked the fuses and they are all OK. The power indicator is on, but the charger still does not provide any output voltage. I have checked everything I can, but I am not able to do anything more to troubleshoot the problem. I believe the unit is defective. I would like to return it under warranty and receive a replacement or a refund. Thank you. Regards L.W

ok power

Parece robusto y de buena calidad, pero no entiendo porque los tornillos para la conexiones son tan pequeños y el hueco tan estrecho. El cable de 10mm2 que viene desde el alternador no entra, e incluso para el cable de 4 o de 6 mm2 hay que poner unos terminales de ojal muy estrechos.
