Bis jetzt tip top

Am Samstag gekauft, bis jetzt tip top. Lädt die Batterie, tut also was es soll. Jedoch ist dies für Schweizer Steckdosen so nicht geeignet, braucht ein Adapter der nicht geliefert wird. Schade und wenn man sich doch extra im Shop beraten lässt wäre ich schon froh um den Tipp gewesen.

lieber nicht

Die Kabel sind selbst im Sommer bockhart. Die Dichtungen der Steckverbindungen halten einen Winter. Das Kabel zur Batterie wurde beim Laden der Batterie viel zu warm - beängstigend ! Austausch des Kabels nicht möglich, da das Ladegerät verschweißt ist. Nun nach 2 Jahren defekt. Kein Service, keine Unterstützung des Herstellers (Made in Germany???). Habe nun ein Ladegerät vom Motorradhersteller, das zuverlässig funktioniert. Hätte mir den Umweg SPAREN sollen.

Netzstecker nicht für CH

Top Produkt aber der Netzstecker ist nicht für die Schweiz... und auch ein Adapter fehlt weiterhin - wurde schon 1x mitgeteilt.

Stecker

Wie immer prompte Lieferung aber leider passt der Stecker des Ladegerätes in keine Steckdose. Irgendwie sind die Stecker für ein anderes Land (GB/EU) gedacht. Bei Nachfrage beim Kundendienst wurde mir dann ein Adapter zugeschickt. Vielleicht auf der Webseite vermerken das der Stecker nicht CH kompatibel ist oder bei Bestellungen aus der CH den Adapter gleich beilegen. Anmerkung POLO: Der Adapterstecker für die Schweiz kann separat bestellt werden. Das Gerät verfügt über einen Standardstecker für Europa.
