Genial, finally, another battery on the go!

Since the purchase of this product I have not charged a single time the phone by cable. There is an additional original battery for the Galaxy S4 and soon battery Nr1 is empty change I him simply in a few seconds later invite him to New, and then take him everywhere with (mitgelieftert is also a small plastic case for protection). To load itself simply use the included charging cable with the Galaxy. The charging time is also extremely short.
Especially for people who travel a lot and do not always have a laptop or a power outlet within reach, this product is particularly well suited. In addition, I can now use my smartphone unengeschränkt always and everywhere (Uni), without having to carry an annoying charging cable.
Brilliant;)
