Which OTG Hub charger cable for Air III?

[bkch0]

I tried the one  http://www.banggood.com/4-Port-Micro-USB-OTG-Charger-HUB-Cable-For-Tablet-Phone-p-975460.html

which is reported working for the x98 Pro by Chris.

I tried it on the Air III but cant get it to charge and see usb devices in mode2.  mode 2 only charges.

anyone have a working model and can show me link where to buy?   Thanks.

Saw a reply to this question on one of the sellers Q&A ( Gearbest.com, I think ).
It said that charging via the OTG hub/port is not supported whilst peripherals are connected. This would damage the Tablets battery due to overcharging so you have decide to either power and use the attached devices or charge the Tablet ( not both together ). Hence the little switch to switch between the 2 modes.
I also some found other ‘otg’ intelegent powered hubs ( apart from the one sold frequently with the Teclast tablet, with the 2,3 or 4 dangly leads and a mode switch ) dont work at all !

I would be interested if anyone knows of a way around this as its scuppered me using a powered USB directional Wifi aerial when abroad in the camper from downloading movies and TV as the Tablets battery wont last long enough to leave it overnight downloading.
