Question 1

Will this work with a  Fire Tv 4k

Accepted Answer

I own 5 of the 4K Firesticks & use this hub on 4 of them. 2 are connected to ethernet with zero problems. I have also added this same hub to my son & 3 different friends 4K firesticks & all work as expected.
There is NO compatibility issue with the OTG cable on a Y adapter. Seller refers to the Firestick usb 2.0 connection which is backward compatible.
For those who have a fast connection, it pays to remember the ethernet connection on a 4K firestick is 10/100. If you require a faster speed, use your wifi connection. Requirement to stream 4K is listed at 68MB/s. 
As an aside, I use this hub with a 128gig SDD drive plugged into the hub as well as the bluetooth dongle of a logitech full size computer mouse which contains all 97 programs which I use running at 550MB/s on ethernet speed averages 90MB/s & have user-disabled 41 Amazon proprietary programs. Reason to use this 3.0 hub is it will carry maximum speed down compatible with the 2.0 usb Firestick connection. My Cache available free space is 3.96 GB of the 5.34 GB available. Some of us are expert level.

Question 3

My firestick won't support a 2t external drive (not enough power).  will this work?  where do i plug in the power adapter?

Accepted Answer

Hi friend,
Theoretically, the USB 3.0 Ethernet adapter is compatible with the firestick. If you want to connect the adapter to your firestick, you need a specially-made OTG adapter that has an isolated power cable, since the hub occupies the power port of the stick. 
If power-hungry devices such as hard drives and printers are connected, you can supply external power to the adapter via the DC5v port next to the included cable.
Hope it helps.

Question 4

Can this device allow external hdd to work as a nas? essentially i could use router to setup nas as i have usb interface on it. but, prefer not to...

Accepted Answer

Nope. It is a USB hub with Gig Ethernet and 3 extra ports, to connect to a PC or streaming box. No other functions like sharing.
