This HUB is powered by an independent transformer. Making it ideally suited to a landline rather than a mobile phone: this is where his only fault! While it resembles other HUB, only the number of ports and changes, depending on your actual needs. But at the HUB Aukey are also performing.
It provides the fastest data transfer rate: 5 GO in 5 minutes from my computer to my DD. Backwards compatible, it supports USB 2.0 models and 1.1. I have not noticed any significant drop between ports transfer rate using 7 ports simultaneously: just little slower compared to tranfer a single port. The transfer rate is the same whether with a USB stick or HDD (external hard drive).
With 2 ports charging intelligent and powerful (they automatically detect your device charging mode), it can connect my I-Phone, the external battery and recharge my camera while working with USB ports. Each charging port delivers 2.4 mAh.
In summary, this is a good product for large data transfers, but also to charge through its own power supply 4 A, to connect a second monitor, keyboard or mouse. The fact that it is powered independently also allows it to plug a scanner. My desktop computer is provided with little USB plug: This HUB is therefore perfect to extend my connection options. Every day: this is a significant comfort.
