Das Ladegerät tut was es soll - Akkus laden. Wie in anderen Rezesionen auch schon geschrieben, ist die Anzeige des Ladezustandes in % recht ungenau. Sehr positiv: die Stromversorgung kann über Micro-USB, USB-C oder Lightning erfolgen. Netzteil ist nicht dabei, macht aber nichts, da jeder genügend davon zu Hause hat.
