Question about USB charging - General Questions and Answers

I cannot find or haven't seen any info about charging with USB cord with the otg cable. What I am wanting to know is can I plug in the otg cable then a 4 port USB hub and hook a USB cable up to the hub and plug into the wall and charge my nexus 7. Want to be able to charge while I have my external drive plugged in. Hope this makes sense please help.

Beware!!!

[Q] Upgrade now my TF won't charge

I upgraded today and now my TF won't charge with the USB cable.
I didn't bring my power connector to work, so all I have is my usb cable. When I get home I'll plug it in and see, but I'm surprised that it is not charging via USB.
Did anyone else have this issue?
ummmm it dont charge through PC usb... need to use the AC adapter to charge...
It does not charge via USB 2.0, but i do believe it may charge via USB 3.0...
I have had no need for an extra charger and have not read any charging cables threads in this forum thouroughly enough.

I thought it trickled charged on USB? I guess not. It charges fine o charger. My mistake.
It'll charge via USB but it's very slow and the tablet must be turned off first.

do you have the dock? pretty sure it works fine with mine. wht rom/kernel are you using?
It will charge from the main adapter from a wall plug in. It will charge from the dock. It will SLOWLY trickle charge from usb if the screen is off.
No im on stock have b70 so no root. And no dock

Yes...It really only works with its own stuff. Some have claimed to have it charge from usb when it was off but I have never tested it.
Are any other similar devices able to charge through usb? Netbooks or laptops? Usb was not designed to be a big power source. Some hard drives require two usb connectors for just a hard drive.

From what i have read in other threads it has to do with the voltage required and how Asus wired their plug.
Use USB 3.0 cables and it will work fine. Also use a USB 3.0 port on the pc for slow charging.
Usb 3 cable works fine here...

Using a usb extension to charge?

So would this be ok or would it damage my phone? Basically I have a usb extension with is basically a usb plug on one side and a port on the other to plug in another usb cable. I'm plugging that into the charger and then plugging in the microusb wire into that to charge. It charges fine but I'm just wondering if it's not good for the phone.
Its just extantion code where you plug in your sammy charger rite? Than you are ok no problem at all. I use this setup everyday.

Basically the bottom goes into the samsung charger and the actual microusb charger goes to the top. Its basically an extension cord for the microusb cable.
I have a 10ft USB cable plugged into my stock charger with no problem.
Not really answering my question lol. I wanna know if its safe for a usb cable to be plugged into another usb cable.
Yes it is!!!!!!

Battery powered USB Y cable

As we know, Nexus 4 can't provide needed power for OTG devices so you need to use external powered USB Y cable with OTG cable, how it works you can read here.
So Im wondering, if USB Y cable have three ports(MicroUSB, USB for power and USB) can we port for power attach on external battery? I have one external battery which gives 5V and 1A, usb on computer gives 5V and 500mA so I think it will be possible with external battery !!
I don't have N4 but planning to buy it so can someone try this with external battery and confirm that it works please?
Anyone?
