Make sure you have a 'charge only' lead to the charger (Shows as 'AC connected' not 'USB Connected') or you'll find you won't have enough power to do everything.

The problem with OTG and simultanous charging is that you'll probably need a custom kernel supporting this.

Because if you use OTG (or a data cable respectively), the phone will only charge with 500 mA max. - this might not be enough to charge your phone while using power-consuming apps (navigation, games,...). If you want the phone to charge faster/draw more current, you'll need to short-circuit the data leads - but then you can't use OTG/data. Tricky...

I think that is not the reason because if i try to charge only didn't work, i think the charging cable is not compatible with moto g like some chargers specific for some patents.
If someone knows a cable like that to charge and use usb stick or something compatible with moto g I would appreciate.

The cable is probably working, but the kernel is not supporting it. If you use a USB y-cable, it will power a plugged-in USB stick / device, but not your Moto G. You will need a kernel or tomorrow supporting simultaneous data & charging. Have a look in the Nexus 7 sections, there you'll find more information about this.

Yes, just as I responded you I made a search on the subject and e found a kernel for it but still no one has made for moto motorola g ....
I hope someone does it soon!!!
