I have to complain much so that none of the offered power packs so far have made over the charging time!
A quick charge capability can namely have considerable advantages!
Because apparently all in today's cars running the power connection of external consumers still above the makeshift cigarette lighter! And if the engine is not running will not occur at the modern day vehicles even additionally switched off !!
Is he still not arrived at the car manufacturers that it (charged) cell phones are now ??
Who sleeps through because as the consumer demand? ...
That's the only reason why we now need a power pack!
Caution, do not forget: When connecting to load devices to the power pack, the Power Pack must first be EINGESCHLALTET!
