Bad against the cable look inside. The strain relief of the charging cable has lots of game. Each wobbler on the cable is transferred to the miserable executed solder joints inside. The few wires in the cable are well abgewackelt after a very short time. The cable is so long that it extends easily to the 230V side. It gets there contact, is at once the whole battery under power. The same applies to the cables from the power plug to the board, which partly depend on individual cores. I doubt that such a product may be sold in Germany. In the hands of children, it certainly does not belong.
