One question, i bought this usb hub http://m.gearbest.com/usb-accessories/pp_599599.html?wid=21,
i tested it with all 4 ports running without power supply, keyboard, mouse, and 2.5" hdd worked connected to the left usb, the one that is nearer to power, reset and function buttons, right usb didn't work.
I didn't test the transfer speed of hdd, didn't even try to transfer anything, i'll do that later, however it was recognized, keyboard and mouse were working, i was surprised, i didn't believe it will work.
This hub has DC in port, and i can't find any info about which power adapter to use, or which cable to connect with usb power adapter, for power supplying the device.
I do have 12V/1A adapter that would fit, but it is recommended to use 5V/2A adapter, i wouldn't want to risk with it.
So if anyone can point me what to buy from any shop, so i don't have to go to the local stores and search for the right adapter.
Update: I did test hdd, using usb to sata adapter, i was watching 1 hour video using Vlc player for Android, keyboard and mouse were connected too, i had absolutely no issues, didn't test transfer speed yet, but i do hope it will be a pleasant experience.
