Did this article mainly acquired to my mobile Raikko dance speakers and be able to load my phone on the go. And he does without hesitation, to load the Nokia phone was no problem at all, when the speakers I had in mind at first, because EasyAcc had stopped charging after only a few seconds. This was but the fact that the battery capacity of the speakers was simply not far enough down although I had about 1 hour operational. Only my Creative MP3 player will not be charged by EasyAcc, but that is due to the company's policy of Creative, these things are only charged by Creative's own chargers that must be expensive to purchase separately. I am very satisfied, the Powerpack is small, handy and has a very good battery capacity, charging is also about 6 hours, the power corresponds halt of a netbook batteries. The charger is very small, but is not overly warm. But due to the micro-USB connector, I could not use any other charger. As a single point of criticism I have to say the fingerprint susceptibility, due to the high-gloss finish looks to every impression. For me, not really bad, you can easily wipe it again.
