It works purely give also with battery and wait, but it is advisable to study the use ;-) One can all batteries the same, but also individually load / unload / refreshen. The current operation is displayed, the temperature of the cells monitored. The charging current can be adjusted depending on the cell and thus of 200-1800mA one can determine the charging time itself, either gentle variant, or just the fast. Rounding out the package by a practical bag and the adapter for the baby and mono cells, This act, however, somewhat delicate. Compared to Ansman Digispeed I lack the 12V adapter, but this is not going to me the loud fan.
