Hi everyone, i have a question.
I wonder if all device that shipped with a USB type-C specifically a smartphone, is able to supply power to other devices ( eg. Charge a phone)?
I have a Samsung Galaxy A7 2017 which comes with USB type-C. I failed to use OTG on this phone. I tried connecting it with type-C OTG connector to charge my other phone but it does not seem to charge.
I have no problem charging or connecting the A7 2017 to my computer.
So I believe that the phone is not supplying power from its type C port.
Therefore, I'm wondering if all USB-C port can output power/ supply power.
Could it be a faulty USB-C port or it might be a software issue?
Any solution to this issue?
Any answer and suggestion is very appreciated. Thanks in advance.
I guess some can. Google might help. My Pixel for example is able to charge another phone!
I am just guessing on this one, but I believe that it might be a software thing, because if you remember the "good 'ol days of usb otg", some devices didn't support it because of software I believe.

However, is there any way possible to charge your phone WHILE using the OTG adapter? They both use the 1 micro port on my phone, but I need to find a way to charge the phone while using the OTG adapter.....perhaps a micro USB splitter-type adapter?????
I was actually wondering about this myself, though I don't think a splitter-type cable would work. I'm wondering if the power connection is on separate pins than the data, though...if they don't share space then I'd think it would be possible in some fashion.

A similar problem is showing up regarding using the mhl port to output to hdmi. Though the original information indicated that the power cable was supposed to charge the phone it seems it does not on the first version (super DUMB).
I have read though that the newer version of the mhl port is 10 (I think) pins rather than the 5 of the original. The newer port DOES allow charging while output is in operation.
I suspect this will also allow an OTG cable that charges while in use.
I am not so sure about the mhl idea anymore. Only one port for everything is ok if it has enough pins/bandwidth to have a breakout box that would allow an external usb drive to be read while hdmi is being output to a screen and power is supplied to the phone. As it is now with only one-at-a-time it isn't very inspiring as the phones get closer to the power of laptops.
What would be really neat would be a box with wi-fi, and the output to hdmi and usb ports as well. A wireless breakout box. Then the charger could be over by the phone which is near the user.

I think this thread could solve your problem.
Oh... I found a useful diagram here.
[Q] How to estimate the power supply capability of my Samsung tablet through otg ？
After much hesitation about the choice for which small otg gadget , I choose this one for its slim and simple looking with a suitable price:
http://www.amazon.com/gp/product/B00GLKI0QE
The following idea is how I design the use situation ： The otg is connected to my Nexus 7. And I planned to plug the Samsung Tablet to one of the four usb 3.0 port. As this is not a gadget with its own power adapter. I worried about the power supply issue. I wonder which could be the main part to supply part. Let alone to add other devices to all the usb 3.0 ports.
Is my idea a practical one ? Anybody who has a wise solution is warmly welcomed.
Hi!
It looks like it's possible to use some USB Ethernet adapters with some Android tablets, but is it possible to have it running on AC power at the same time?
I suppose that this can be achieved with some special OTG cable, if it is possible at all. Have anyone been successful with this?
Please share what's your setup, i.e what tablet do you have, what Ethernet adapter works with it, and what kind of OTG cable are you using.
Direct links (Amazon, eBay, etc...) are very welcome for Ethernet adapters and OTG cables.
Thanks in advance!
PS: Hopefully this is the right forum to post these type of questions.
Hi, I tried with a otg cable which had an additional port for power but it's just for when u use hdds who needs more power then 450 mA to run. Android is not allowing to charge the phone during USB otg usage.
I recently purchased a combined power and otg cable. it has a connector to plug into the table and then 3 usb sockets. 2 provide otg and the third is to connect a standard usb charger.
I'm using unified lineageOS 13 and whilst the OTG side works fine in both the otg sockets , charging does not. The cable lists the 3110 as specifically working and whilst I admit it could be a faulty cable it could be that
a) The 3110 never actually supported this despite the product claims
or
b) There may be some support needed at the kernel level to allow for combined otg and charging
Much appreciate if anyone has had any experience with these working successfully with specific ROM/kernel.
Thanks in advance.
Our tab use 20 pins connector, otg and usb have different pin connector. So you can't charge your tab while using otg cable. On our tab, the third connector is used for powering conneted devices.

Is this the device you tried? I have never tried it - but would be interested in whether it works or not (and the cost):

I really need to call my Doc and schedule my next lobotomy, cuz this isn't making sense. Why is Google's adapter different from one I kept back from one of my many Samsung handset purchases?
If anyone knows the answer to this hardware riddle, or has had a different experience with their OEM supplied "Data Transfer Tool" , I'd love to hear about it before I have this procedure done! (ty)
When you plug a USB into the pixel, doesn't it have the option to choose to charge from device in a notification shade?

Negative, or at least mine doesn't. But the Samsung adapter I've had since selling my SM-N975U1 (Note10 Unl.) does let the charge happen with no hassle. Also, I try think this might be one of our fixes forthcoming (I hope) under a blanket USB-C fix? My Pixel 5a (5G) had no issue with the Google adapter for charging as I recall.
If you're talking about the adapter that came in the box (male C to female A), the USB-A cable you're using could be the problem. Even when cables have pinouts for pass-through power they don't always work for all devices. This article explains how the Pixel 6 is more fickle about charging, which also hints at why you don't see the same problem on a Pixel 5a.
Thanks for the link...I knew my 5a adapter allowed the charge, so my issue may be broader as I was using my Google supplied cables. Wonder why the G-Whiz kids couldn't accommodate us on a more universal adapter as they didn't spring for throwing in a power supply on the Pixel 6 Series deal?!
What's that little birdy, what did you say?chirp..cheap..cheap!
Did you not want to use the USB-C cable that came with your phone? Or you didn't have a charging brick that has USB-C?
No, it charges fine with the supplied OEM cable, it's just I've never used one before that was made to be so task specific. I thought (until now) they were all made to be multifunctional like my Samsung model is.
