It comes here alone. There is also a pack with the transformer (2.1 amps).
We need to add a good transformer for recharging is rapid (one that came with the Galaxy S5 is in 2.1A, the same as the full package).
And so buy the original brand: it is useless to save a few euros to end up with a Chinese pale copy that may damage the batteries by overloading, and you end up throwing anyway because defective!
