MicroUSB Y Cable topic

Hey guys

I have a microusb y cable connected to the tablet. A USB to ethernet dongle is attached to one end and a microusb cable USB connected on another

The microusb cable is connected to an AC charger but the tabet doesn't like it and is going down to standard usb charging speeds/power

Would there be anyway to make it charge AC because when I play games on it the power draw is faster than usb charging speeds

Thanks
