It is supplied without accessories and instruction manual that you do not really need. The essential information is found in the product description here on Amazon. It is made of black plastic in piano finish, has a compact shape and has two USB charging ports with an output voltage of 5V / 1A and 5V / 2.4A, at which two mobile devices can be loaded in parallel rather quickly. If you load two equipment to be used at the same time, this also happens with the maximum possible output voltage of 5V / 34A. The processing makes a very good and robust. A heat generation can not be determined at load time. I've also seen in cheaper devices already different.
Overall, this is a well-made charger that my mobile device loads quickly and reliably and can also be very well used because of its compactness and low weight as a travel charger. For this and for the fair price's by me 5 stars and a buy recommendation.
