FAQ

Für welche Geräte reicht die Leistung von 300 W aus?
Für Geräte wie Smartphones, Tablets, Laptops, kleine Kühlboxen, Ladegeräte und kleine Netzgeräte bis zu einer Dauerleistung von 300 W. Hohe Anlaufströme können die Leistung kurzfristig belasten.
Kann der Wechselrichter dauerhaft im Fahrzeug betrieben werden?
Ja, sofern Batterie und Fahrzeuginstallation für längere Lasten geeignet sind. Länger andauernde hohe Lasten und entladene Batterien sollten vermieden werden.
Was ist im Lieferumfang enthalten?
Polklemmen, ein 1,94 m langes Kabel mit 12‑V‑Stecker, ein Kabel mit Klemmen und Buchsen (47 cm), zwei 20‑A‑Flachsicherungen, eine Sicherungszange und eine Bedienungsanleitung.
Ist der Wechselrichter für Starthilfe geeignet?
Nein. Er ist nicht dafür ausgelegt, leeren Starterbatterien Starthilfe zu geben; er versorgt Verbraucher mit Netzspannung aus einer 12‑V‑Quelle.
