Compact, powerful and adaptable.

The voltage converter is compact and adapts with the built-chip to the terminals on.
It is equipped with 2 * 2.4A very efficient. This is necessary but not sufficient condition for "fast charging".
Some devices expected on the data inputs certain (unfortunately not always the same) voltage level, others a short circuit between the data lines other an open connection. This device adjusts itself accordingly and remains quite cool even under load.
