Purchased to charge my tablet and simultaneously use the USB HUB what appeared to be a good solution. Except via the micro USB female connector hub, the load is not done ... So it becomes a simple USB HUB ... I may be a faulty model. Seller contacted thereafter. To be continued ... Next: After contact with the seller, it is noted on the data sheet: no charge via the micro USB connector ... Too bad, this would have been perfect if not. I added a star because it is not a failure of the coup.
