Not fully charged!

After receiving the unit I invited it as prescribed. But even after the maximum recommended load time green LED light that (indicating the end of charging) not permanent. According to the manual, it should do that but.
In addition, the included charger is more likely to be described as a toy. It is a normal transformer power supply with about 12 watts of power. A charging time of 48 to 60 hours is no longer surprises me since. State of the art is a powerful switching power supply. By that I do not heating at least the environment.
The unit went back again.
