low charging current.

With these offerings, where there are several completely different products, you have to pay close attention what you read a review. It may be that all other products offered here deserve their 5 star rating, but the "1byone USB Smart Charger Super faster Hub with 7 USB 3.0 data ports" it is not safe.
According to product Beschriebung the Hub has a "smart charging port (5V / 2A)". Good that he's smart, but he does not invite. Maybe he's so intelligent that he is somewhere else with the idea and has simply forgotten on the store.
My smartphone is already contained in the hours marked as a charging port connector and the change in the charge level of the phone is marginal.
I even crawled under the table to even check if I have plugged the phone also to the correct port. Yes, everything is done correctly. I am again the idiot who has gone a product description on the glue.

That the hub is a USB hub and works, which is the least I expect me, so I distribute in this review no consolation Stern, also not for the beautiful black finish, or that efforts have been made.

I wrote last week. Today I correct my review and forgive at least a few stars.
After I read a review on PortaPow Fast Charge Adaptor Smart Charge, the URL to the review:; ASIN = B00K4XR3LW, maybe I'm clever.
I'm not sure that my phone will slow may be because it does not take up more power. Possibly comes the that the USB port is also available for data transmission.
It may be that the HUB really 2A provides. However, I will examine the unspecified, so a lot of time I did not.
Two stars deduction there that the product description does not address it, and I do not know exactly what is to blame for the weak charge current.
