compact - ideal for all who are not afraid of an empty battery

Charging cradle - no charger - pleasant small dimensions. Original power supply and cable must be used. Therefore, one can not simultaneously charge battery replacement and those in the cell phone battery. But this was known to me.
Works perfectly. Only the insertion direction is unchecked. So you have to look where the charging contacts are and insert the battery accordingly with some force.
An LED indicates when derAkku is fully charged.
Overall, highly recommended for anyone who works with a second battery.
In this compact presentation found nowhere else.
