1. Design in Germany. And a chip controls the process: Avoids mistake, ensures charge efficiently and accurately.

2. Adopt clipper-built aluminium casing which has better heat dissipation function. Different from traditional design, it does not use fan in order to reduce volume and weight. It is more convenient to be taken with.

3. It can suit various using environments through an adapter which has wide voltage range (12-18V DC) or car-charger connection.

4. Automatically detects 1-3 lithium cells battery packs, restores low voltage cells and displays the situations.

5. It has a good balance effect. The voltage tolerance of single cells in the full charged battery pack is less than 50mV.

6. Ending voltage of the product is between 4.18V-4.24V(midpoint is 4.21V). It is little higher than the international standard which is between 4.15V-4.25V (midpoint is 4.20V). Considering the characteristics of large current discharge, the capacity proportion of battery has been increased in order to improve the large current discharging time.
