For winding and unwinding, this is not very practical because of the side wire outside the impeller which exceeds about 1 meter, therefore it rotates at the same time as the main wire is wound or unwound on the impeller. In addition there is a switch that should not be forgotten to operate on pain of having no more juice after 24 hours, you just had to know!
The drum is easy to unroll and is equipped with a thick cable and is solidly processed overall. Unfortunately, the thick plug on the side makes it impossible to easily roll up the cable again afterwards. The plug is simply too bulky for that and constantly hits the ground or blocks the winding process. An improvement with sliding contacts is urgently recommended here. For this deficiency I find the drum too expensive.
Von der Qualität her in Ordnung und robust. Leider ist der Stecker am kurzen Kabel so klobig, dass ein schnelles einrollen nicht möglich ist (haut ständig auf den Boden und verkantet). So dient die Trommel nur einer platzsparenden Lagerung aber leider keiner Zeitersparnis beim Aufwickeln. Trommel mit Schleifkontakten oder zumindest abziehbaren seitlichen Anschlusskabel wäre sinnvoll gewesen.
