Hai.
So I was thinking a bit here... Is it possible to charge and sync the tablet at the same time?
Im planning on making a charger port on the PC like this
But, wouldnt it be possible to attach the data cables from a USB port as well, basically making it a 12V USB port?
Or, does the tablet shut off all USB data when it receives 12-15V? Or is the charger cable wired in a weird way that it sends 5V to a different pin on the tablet than the 15V charging voltage?
Also, would it be possible to make something similar for the USB Host Dongle, making it possible to use USB stuff and charge the tablet at the same time? That would obviously require modding and adding a special charging port though.
What do you guys think? Am I thinking completely wrong here?
Sorry, Im just gonna try a bump on this.
If I could figure out a way to charge the tablet while using the USB Adapter it would be awesome, since then I wouldnt really have any need for the keyboard dock (even though its very nice, its still quite expensive when all I really need is a USB port).
Well guys, since youre all chickens ( ), I went ahead and tried charging and syncing at the same time myself...
I'll let the screenshot speak for itself
edit: fix'd the picture...
I just recently purchased a USB to Go dongle for the SGS3 (the adapter allowing you to use the SGS3 in usb host mode, to connect things like flash drives, mice, hubs, etc). Everything seems to be working quite well, but I do have a question maybe someone can answer.
I was hoping that, if using something like a powered USB hub, that I'd be able to plug that into the USB to Go connector, and that my SGS3 would charge through the hub. Maybe this was a foolish hope, but I'd hoped nonetheless because it seems that there's going to be quite a bit of battery power drained by trying to power devices like this. I had hoped to basically set up a sort of docking station where I could connect the phone to the USB to Go adapter, plug that into a powered hub to have it charge, connect a flash drive, mouse, and keyboard to the hub, and then use HDMI out to a TV.
It seems even with a powered USB hub I'm stuck not charging so this setup obviously doesn't last long, which leads me to wonder why it's set up like this.
I'm sure I'm missing something or not thinking it through or maybe it's just not possible. But any insight into this, or is it just not possible to charge while using the phone as a host?
I want to connect my Galaxy S3 to a USB hub but also charge it at the same time. That way I could connect my keyboard, mouse, thumbdrive and PS3 controller while still charging my phone. Is this possible?
I was thinking through a Y-cable I could charge it while the other side connected to the USB hub.
Does anyone know if this will work natively?
Do I have to do anything to my GS3 to enable this functionality?

The S3 automatically charges when plugged in via usb, albiet it's a trickle charge and therefore MUCH slower than if it were plugged into a wall charger.
I would like to be able to buy a cable so that when i am away i can plug my Tab into an HDMI TV and watch movies directly. I know that it is possible but before i root my tab, are there complications on rooted devices that would make this function unavailable?
Any cable recommendations greatly received.
I use MHL cable. Kind of 3 way cable. 1 to your device, 1 to the hdmi port and another 1 is usb charging port

I went for the Chromecast and Allcast app from clockwork. It gave me some trouble initially but now is working well. I'm yet to test it with WiFi AP as the router. I hope I can use it when I travel without a bringing a router

is there any way around this without plugging into a charging port?
I used to use the Ipad and you only needed 1 cable for that...
I wanted to use for presentations so the last thing i want is needing to plug it in charge!
Thanks
its working without charging. but your battery will drain fast.

Great - how did you do it? lol
I have an MHL-HDMI cable and it was just not connecting at all (without charging) infact I didnt even know you had to plug it into a charger into I read your post, I just went to a meeting room and connected all up again, this time plugging in the charger and hey presto it works!!
As soon as I pull the charger out I loose picture - does that MHL device need charging up?
dont know... mine just work that way... lol... you can also plug in to the usb port on the display.

Because some TVs have MHL enabled HDMI ports that don't require external power.
Anybody knows if its possible to connect usb OTG host and charge the tablet at the same time, i found out a way to enable adoptable storage on USB drives so im planning to offload my console games(borderlands, half-life,etc) to an external hard drive cause i only play them at home when im in console mode, and if it is possible anybody knows where to get one from a reliable seller?
Haha just bought an adapter on amazon.

Does it work charge and enable usb host at the same time? The current one i have acts weird, if i leave tablet alone, usb plugged in host mode as adopted storage my k1 charges, but if i start using it, even on light usage, battery discharges even if it indicates it is charging
Haven't tried it yet. I'll let you know ASAP when I've tested it.
This thread is a little old but still applies:

USB OTG and Y cables?
Sent from my SHIELD Tablet K1 using Tapatalk
Okay, they one I've got is damaged. Gotta send it back.
The ones Exile suggested I've one of them. Though, they connect all to big female USB! So you'd need another USB cable (Big male USB to micro male USB for the tab).
I've been using this one, and it works pretty well for charging and using OTG at the same time. But it won't recognize USB devices unless the charger is plugged in, probably because it has a built-in hub.

Thank you for the replies and suggestions, looks like the one im gettting is the same one by @primaleph
Y OTG cables do NOT work with the Shield. I tested a bunch and it's either charging or gamepad but never both simultaneously.

Well actually they do, very2 slow, i hooked the OTG i bought to my charger, my tablet and my printer, then started doing some typing work while listening to some tracks on spotify max volume and at about 20% brightness,, after i finished and checked my battery it went up from 95 to 97, also tried the same with a usb attached, so for light loads it does charge but for gaming, even i lose charge when playing games such as vain glory while the tablet is directly charging so im sure its still gonna drain but probably not as fast as not charging at all, or another thing is not all OTG Y cables are configured the same me and @primaleph just got lucky with the ones we got and yours are probably the not compatible ones
A printer?
Anyhow, it doesn't show the lightning symbol if two devices like charger and gamepad are simultaneously connected. Whereas, using just one of the devices works.

Yeah i use an app called printershare, it allows me to use printers directly via usb connection cause i still own those old printers with no wifi connection costs 10 bucks for the license though, i tried with my old usb gamepad and it also charges and gamepad works, i think you need a more powerful charger, i use a tronsmart quickcharge 3.0 with a 2nd port with a max of 6.5V 3amp output which i use to charge it in OTG mode, 5V 2amp chargers should work but sometimes the power cuts out on The devices being connected, happened to me while on a boat trip, boring 2hr ride, me and GF wanted to listen to some music but we both own over the ear headphones not those little earphones, i charge my shield with a powerbank that provides 5V 2A output, plug it in the OTG and use a usb soundcard with with two audio jacks so we both could listen and throughout the trip there are times the soundcard would lose power which was pretty annoying,
Heres a screen recording where it is charging and i attach devices one by one to my shield tablet
