I was expecting an adapter at the very least. My old QC 2 phones lasted for a VERY LONG time and I use them several times a day, every day. I decided to open it up and found that the battery was not 10,000 but a 5,000 mah battery named Great power. However, there is a high level of resistance when opening, putting on, and adjusting. Emma shoe pop on your feet. Was the highest that I found. I’m very pleased with my purchase. Die Männerschuhe sind etwas breiter, aber max. I found that they were not really Nike shoes. This is my second purchase of this same unit.
