Perhaps the sheer amount of qualities he has to reproduce is the reason why he electrocutes himself before using his abilities: instead of understanding the theory, he analyzes what electricity does to his body and mimics it. It is the only explanation I can find, since storing electricity in one's body does not seem to be related to Transmutation at all. Sorry, this last part was a bit of an off-topic.

I think your misunderstanding what Killua is doing with his Aura. He isn't mimicking the properties of electricity with his aura; if he did why would he have to recharge at a power outlet? Couldn't he just synthesise it himself? Instead, I think he's changing his aura into a battery of sorts, which allows him to store electricity for later use; therefore he isn't turning his aura into electricity, but letting it be stored inside of him. If not he would have to change his aura on a subatomic level to take on the properties of highly charged electrons. Which doesn't seem that easy for a 14 year old.
