(SOLVED) Need help with USB tethering

[ChunkyPanda]

In my house i get roughly 100kbps which has led me to resort to USB tethering which can net around 500kbps with our 3g connection, however when I am outside using the tethering I can get ~2-5mbps.

 

So I tried to use this device 

https://www.cablechick.com.au/cables/high-end-15m-usb-20-repeater-extension-cable-a-male-to-a-female.html

 

I used this cord and ran it outside connected to my tethered phone, it works great with my internet now seeing 2-5mbps. 

 

However the 15m cord does charge the phone, it is not fast enough to keep it from going flat. 

 

To try and remedy this by using this device.

 I connected the data connector + power connecter to the 15m usb cord and the power-only to the wall socket. When connected to the 15m cord, it does not charge or register the tether. Is it because its 3.0/2.0, can you use different cords?

 

Any help would be appreciated

For some reason, when I changed what output the 15m usb cord was plugged into, it started working.
