[Q] USB OTG Cable with additional power

Hello, we all know that there are USB OTG Cables with extra power plug (Y cable) but those are supposed to power external device like HDD, DVD, or anything what consumes more power than our android device can handle.
But my question is: is there any USB OTG cable with additional power plug but for simultaneous tablet / phone charging while USB stick is used?
I want to watch something long (i.e. TV Show series) from USB stick via OTG cable but I cannot simultaneously charge my tablet, so if it take too long my tablet will be out of power before I stop watching.

That means I have to add a resistor only to usb connector or just need a different kernel, or both?

On the native firmware say that this support function is disabled. Personally, I use this CivZ-FLEX-ЛУЧ-REV3.6.2 + SphereXtreme, where works flawlessly with OTG + charging resistor 64.9 K.

I call BS!!!!
I have a stock firmware, and have been using all kinds of USB cables. Found the best are made from Sony/Ericson and Blackberry. Once you have a quality cable your charging issues will go away.
Right now I am using a 7 foot cable that is from a Sony. No charging issues and works perfectly.

Lately I found another MHL cable 2hich is called HDMI to Micro HDMI, and that micro HDMI plug looks exactly like micro USB. Will such cable work with Note 8 properly without additional power?

The version of MHL our device supports requires a power source external to the tablet. That means the adapter itself needs to provide the power (battery or power adapter) or can pull enough off the HDMI cable, which is usually not enough juice to run the connection.
MicroHDMI and MicroUSB are also not physically compatible (won't fit the same port and different pin outs) even if they look so much a like. MHL typically uses MicroUSB at one end and full sized HDMI at the other.

This is correct u need to put a 63-65 k resistor between ground and Id pin(pin 4 &5) on USB connector. Doesn't work on civatos 4.4.2 as of now. USB host works fine with regular USB host cable but no charging when u use a y cable. I use civatos 4.2.2 kernel also. Works on yyks note 2 4.3 port also..
I have test multiple times. I use a USB dac in car and need charging and USB host.

what resistor should i use on my sghi257m samsung galaxy s4 mini otg usb cable?

on my dads galaxy s5 Active it shows message that says: Do you wanna enable power sharing
is that OTG? on my S4mini nothing pops up

I know this thread is really old but i want to use a USB DAC so need at cable with a resistor as mentioned above but What ROM should I use now?? also is there anywhere I can buy a cable with resistor in it or do i have to do it myself?

USB adapter + charging?

Hello,
I have the TF300T (without the keyboard dock), and I want to get a USB port dongle. However I have two needs:
I want the USB port to provide enough power for a USB 2.5" hard disk. I suppose I can use a powered USB hub for this?
I would really like to be able charge the tablet when the USB dongle is on. Is this possible?
Thank you

If that USB HDD requires 2 USB (one data one power), then a powered hub is your best bet.
When the USB dongle is in, it takes the place of the charging port. You can either charge the tablet or use the dongle.

[Q] Adding power supply to USB OTG cable?

I have an USB OTG cable that I can connect some of the peripherals with (like flash storage), but most of the accessories won't work, presumably because of the lack of power supply. I watched some DIY videos (and threads here on XDA) on how to add external power supply to USB cable, so I'd like to ask some questions about such matter:
1. Is there any chance of damaging the phone, since there will be external power added? Can it make the micro USB port unfunctional?
2. If I connect more power than needed, for example, if I connect 6V current, while the standard USB current is 5V, can it damage the peripherals I'm connecting to?
My phone is Xperia T (confirmed OTG support)
Thanks in advance!

How about using USB Hub, some USB HUB equipped with independent power supply.

They aren't available where I live, and besides, they cost much more than doing it DIY-way.

1. Supply power only on the periphery. By phone take only 2 wires DATA.
2. Only stable 5V. And 500mA or more.

[Q] usb otg aca (otg + charging)

Does the Note 4 support ACA (Accessory Charging Adapter) to be able to charge the phone at the same time as using a usb OTG adapter?
I want to be able to use a USB DAC and charge the phone at the same time. Is this possible?

It's a very good question. I am curious about it as well.
I have 2 pieces OTG "Y" cable. 1 of them can to charge my phone but the phone can not recognize the usb flash drive. The other can not charge the phone but the phone can recognize the usb flash drive. I need a mixed cable from this 2 )

I need a quality OTG cable, any recommendations?

USB OTG Host and Charging simultaneously

Considering to use a Huawei Mediapad X2 7.0 for my 2DIN car install, since the dimensions of the tablet are nearly identical to 2DIN,
Therefore I would like to know if the device supports USB OTG Host mode and charging the battery of the mediapad simultaneously using a certain Y cable?
Thanks, much appreciated if you can give it a try!

Not sure about OTG Host cum charging combination because my understanding if you use OTG Host mode very likely you plug in a USB OTG thumb drive meaning you cannot charge at the same time.
However connecting the X2 micro USB port via standard USB cable to my laptop, I noticed I could use it as an USB device and it charges at the same time albeit not as as fast as a dedicated charging.

Yes, but not OTG.
I can confirm that, on my side, using an OTG hub with a external power plug, no way to have the device charged by external power when in OTG mode.
It is OTG or Normal charge and functions via USB.
Seems Logical because the Phone is supposed to provide the power to its USB accessories in OTG. Just my HUB has a switch that provide power to those accessories instead of the phone Itself. May-I add that switching this power button on the HUB does not function until you had unplugged & replugged the Hub in the phone after switching between the two modes. I'm afraid of the survival of the Micro USB plug of my phone, on the long run, with all those plugin, unplugin actions !!!

It's possible but with anothere Device the Nexus 7 (2012/2013) with Timurs Kernel. What's the difference of this kernel to the normal kernel, so OTG with charging is working for this device,too.
