Optically not a highlight, but metrologically very good

The device has a low internal resistance and hence a low voltage drop. Precisely because basically moved the voltage to be measured range by only a few tenths of a volt to 5 volts, are the important features. If the specified measurement accuracy is halfway reached, the excellent values ​​would be.

The very low consumption, it is possible to measure not just output capacity, but also recorded. This way you can determine the capacity of the battery pack (Power Banks). With luminous or illuminated advertisements or at too high a voltage drop, the measurement would be too greatly distorted.
