Can I charge another devices using my LG G4 as a power bank? That means if it support inverse / reverse charging, which I presume doesn't support.

I used OTG cable for connect LG G4 to a tablet. and one of them was charging.. I don't know which one. You can find it out by using OTG cable and usb a cable..

Hi, anyone buyed an otg cable with male/female micro usb-usb 2.0 to connect external flash drive and keep charging the phone at same time?
I have bought that but only works the usb 2.0, i cant charge the phone. Sorry but i cant post the link of the product, here is a picture of them.
Sry for my english.
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.

Yes, i tried but i cant charge. I tried with other phone and works but dont have otg support.
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!!!

hey
im looking for otg cable with power charge
thats mean i want to use otg (plug a mouse) and charge the g pad at the same time
is there any ? and is it possible at all ?
note: i found that sony LiveDock do this to their phones, but im not sure if it work with our tablet..
as far as I know, when used in host mode, the USB cannot be used to provide power to the tablet, only can the USB device connected via OTG receive power from the tablet.
OTG charging

My Dell Venue 8 Pro (a Windows 8.1 tablet) does this with a $20 accessory from Dell. You could order one from them and try it.
Unfortunately, I just wasted over $30 on a Valarm IoT OTG Y cable. It does not work at all as a host cable for any USB device on the G4. I was hoping to use the Valarm cable to connect a USB DAC and charge the phone at the same time. The cable will let me charge the phone but whatever I connected to the USB female port is not recognized. If anyone finds a USB host cable that allows charging, please post!

From what i understand otg goes one way or the other it cant act as a host and carge at the same time. It flips the charging circut to flow out instead of in. Ive been through this on a few phones tried even straight wiring a powerline to the otg itll power the usb device but not charge the phone.

The manufacturer of that cable clearly states that it'll charge a samsung phone, not confirmed working on a G4 though. Here is the link, http://shop.valarm.net/products/micro-usb-host-otg-y-cable-with-micro-usb-power-for-samsung
I wish there was a way to enable charging using OTG.

Yea me to i have a few devices that hook to my car that drain my tablet and phone batts and it kills me the only other way ive got it to work is hard wire a charger to the phone. But of coarse this is a old throw away gs3 that im talkin bout not my g4. I havnt tried on my g4 yet but its all phone specs has to have dual charging circuts cause they can only flow one at a time. Now some new devices i know. Do support otg with charging capabilities.
Is there any way to have USB otg and phone charging at the same time (with an Y cable) ? Maybe with a custom kernel?

From my un derstanding the flow can only travel one way on otg. Out u can charge or power what evers hooked to it. But from what ive read the device has to have dial charging circuts.
And please from now on post question in q and a section
Would wireless charging work with USB otg device connected?

no it doesn't.... As soon as I plug the otg device, the wireless charge stop.
to support it we need a custom kernel. Nexus 7 has this custom kernel...

the power supply power both the phone and the otg device.
I sure hope a developer works on this feature!

A little late reply, but I have good news for you - G4 (at least LGH815) has OTG with charging out of the box.
The problem is, that G4 in OTG mode gets less than 500 mA, so it will slowly charge, but only with everything off (screen included) - so what we need is a kernel mod to enable full power charging (1800 mA) while in OTG mode.
Good news, everyone!
Apparently, G4 detects charger type only on initial attach - we can use this little exploit. We need some plug and cable tweaking, or, as in my case - a simple electronic circuit to do the trick.
We need OTG cable (ID pin grounded) with external +5 V on VBUS (red), D+ and D- (green and white) shorted, and OTG device already connected. Next we attach cable to phone. G4 detects short on data pins, as in typical wall charger, so it sets itself into AC charging mode (up to 1,8 A). Now we need to disconnect D+ and D- to allow normal data flow between OTG device and the phone. As soon as data pins are unshorted G4 detects OTG device properly, while still CHARGING IN AC MODE!
Tested on my LGH815 running stock LG Marshmallow.

ima give this one a whack sounds promising
i have a LG G8 ThinkQ phone. it has a completely broken screen. i would like to connect it to a usb-c hub so i can connect a monitor/TV, a mouse , a keyboard and a charger, so i can supply power to the phone while using it essentially as a computer on a TV. i could buy just any usb-c hub, but im guessing some are more likely to work than others. im hoping someone has already tried this and found a usb-c hub that works to accomplish this task, and will see this post and let me know which usb-c hub to buy. if so, please let me know. thanks in advance
