The video adapter 220V is not good on Amazon, it comes with a type of laptop AC adapter Pc. So the power is much more impressive and less boilerplate that a type mobile phone adapter (as pictured).
You can enable or disable the power supply or direct feeding of Pc, but again the "ON / OFF" button and tiny, you need a pen tip to move the switch!
Apart from this it must his job: directly recognized by my PC and media gateway, the smartphone that load without problem, the USB 3 works well as well as USB 2 and 10 ports make it a hub more than well supplied!
I just regret the shortcomings outlined above 2 because it would have a good quality / price ratio in my eyes!
A to change to make it a good product AmazonBasics!
