Preliminary Specifications

 in comparison to the data of the elder nextGeneration

To the Features
To the Prices

Remarks
 (**) automatic cut-off may be problematic with 1 – 3 cells,
so we recommend - as before - to use more or equal than 4 cells.

(***) The higher cell count is valid for a supply voltage of minimum 13.8 volts.

next 14-350 and next 14-500
Caused by the high power of the next 14-350 and next 14-500 we equipped them with
two - relatively quiet - fans instead of one loud fan.
These fans are varied in speed depanding on the existing temperature on the charger.
Both together are essential less loud than the power fan of the next 10.36-12.

next 10.36-12
Because of the high discharge power at power supply use (or with a fully charged car battery) we use a more powerful fan than in the other chargers of this series.
For this reason the noise of the fan (if it really works) is louder than the noise of the other fans.
All data specified for ambient temperature of about 25 °C
