Device was after two days there, content as indicated, the shame (as indicated) no charger for the Pack itself is doing. So just a leftover phone charger had to serve that meets the stated specifications for loading the packs (lt.Beschreibung). Unit was fully charged when unpacking and was immediately used extensively, two mobile phones were still charged 75% during a meal full and two half-full load (2x S3,1x S3mini and 1x Razar i) after that was the Pack! At the 2A connection it seems to load a bit faster, the charging time is likely an original mobile phone charger to stand for nothing! Strong buy recommendation.
