(Fordex Group seems to be a fake company, they just get these cables off chinese manufactorers, and the quality seems to be the same of the Amazon/Ebay counterparts, excepts the shipping is local to the USA, and faster, and the cables seem to work ok, and also ok quality)
Anker® Astro 3E 10000mAh Dual USB Backup External Battery Pack Portable Power Pack Charger for most Smartphones, Tablets and other USB-charged devices
Probably overkill. This thing is heavy and big (5.6 x 2.8 x 0.6 inches ; 8.6 ounces), but for any tablet, I need at least 2.1A output (this one does 3Amps)
WD 1TB Passport Ultra Edition
Meenova MicroSDHC Adapter for Nexus devices in mind
So, I have tried both ElementalX, and the Glitch kernel with stock based ROMS (CleanROM right now), and it's sweet. I am able to give power to the 1TB HDD, and also the tablet at the same time, and read/write to the external HDD to watch movies, and move files using Stickmount Pro + ES Explorer, or Nexus MediaImporter with a prettier UI (bought both just to support) using the Glitch Kernel, and that Y OTG cable.
I can also disable charge mode, and connect the 1TB directly to the tablet to read/write, however, using the tablet to power the 1TB HDD is not good, it's awesome for the small Meenova tiny adapter, but not for the 1TB HDD (slow dowsn, gets too hot, and drains fast).
I can also use the Meenova MicroSDHC reader with the same Y OTG , using a MicroUSB to USB adapter that came with the Meenova adapter (because it has a MicroUSB plug that should go DIRECTLY into the tablet)
My problem is that I wish to do both; charge, and power both, tablet and 1TB at the same time with the Y OTG cable, BUT, also be able to plug the Meenova adapter directly to the tablet without having to use the Y OTG cable, and charger, which I can't.
The option enabled on the glitch kernel to allow me to charge, and OTG at the same times is this:
"Enable USB+OTG Charge mode
Allows charging in USB host mode (disables self-powered OTG)"
"(disables self-powered OTG)" I guess this is what doesn't let me plug, and use the Meenova directly into the tablet without a power source
Does anyone know if there is a way to be able to do both?

Related to this, is it possible to run two drives/card readers at the same time?
What I would like to do, while traveling, is similar to the setup you have with the battery pack powering the external drive. I would like to use a card-reader and external drive at the same time to process my photos and gopro videos from the memory cards to my external drive directly, rather than going from the memory cards to the nexus, then the nexus to the external drive.

Hello. I am able to do this with my setup. Read carefully though, you don't want to break or damage a 1TB HDD, but I'm no electrician either. Also, the read/write speeds between microSD and HDD are ok-ish. Read on:
Sorry for bad quality pic, I have the oldest phone ever at reach :s.
Ok, here's the hub that I bought, which maybe the culprit of the slow transfer speeds maybe? I don't know. Also, sometimes the "Remaining time" may not be the most accurate. Considering the 1TB HDD is USB 3.0, and the Micro SDHC is class 10 (the fastest supposedly).
Also, the movie is 2.43 GB @ 520 KB/S may not be that bad for pictures. I don't know. I can make more tests with pictures if you want.
Onite® GrayBean Samsung Galaxy Tab 3 Card Reader SD(HC)/MS/M2/TF 7 in 1 Card Reader, 3 USB 2.0 Port Adapter HUB, and OTG Adapter, Compatible with Samsung Galaxy Note 2 Note 3/ Note 8.0 / Galaxy S4 S3 / Nexus 4 5 7
It is the "Tab 3" generation of that hub, and the more expensive. I just bought it for fun really.
Here's something that worries me though. I'm almost sure that I damaged, and broke my previous external 1TB HDD by using only 1A (amp) as a power source.
I was using my trusty original HTC wall charger. The label in it clearly reads 1A output, and that's ok for cellphones, but maybe not for a WD 1TB external HDD. I say original, because Amazon sells a lot of FAKE HTC wall chargers, because the originals are GOOD quality for their original purpose.
I say this, because when using a 1A wall charger with the 1TB HDD, -AND- the tablet, it seemed slower, and the sound of the spinning disc inside sounded weaker as well.
The 1TB HDD would only 'sound' normal, and fully working (and NOT weak) when using at least a 1.35A source from the original wall charger for the Nexus 7 2013, which just happens to output 1.35A.
The only reason I don't understands this is because all laptops, and PC's draw out only 0.5A, which is a standard, and the WD 1TB HDD works just fine when plugged into them. So, I don't know... all I know is that I don't want to use a 1A source for the HDD, and the tablet at the same time, and I see many people here saying that it works just fine, but they maybe forcing it, because that 1A is used by the 1TB HDD AND the tablet at the same time. Be careful, and don't use the tablet as the power source for a WD 1TB either.

Bump.
Anyone know a way to be able to do what's on the first post?

Charging + external 3g / lte stick
I tried to hook up 3g and charging at the same time.
But it didnt work. Can anyone else try this?
I build a y cable of my own. Charging and mouse/ keybord is working. But not 3g.
I guess it doesnt get enough amper for the 3g stick, so same problem like 1. Post?

Use a powered USB hub, this is what I use: http://www.newegg.com/Product/Product.aspx?Item=N82E16817182174
I copied this configuration: http://img.photobucket.com/albums/v514/JTrue/IMG_7270_zps331e5e64.jpg

Guys, you're changing the format of the original question :S
I don't mind helping out, but would like to know about the original issue...
As for the 3G question; Is that a 3G dongle or hub people use to have internet through a carrier?

USB OTG Adapter

Has anyone been able to find a USB-OTG adapter for the Galaxy Nexus similar to the USB adapter for the Galaxy Tab (pictured below), i.e. one that's just a compact adapter without a cable between the two sides?

You use that one with the Galaxy Nexus?
Looks like it has a MicroUSB-A plug, which shouldn't fit into the Galaxy Nexus's MicroUSB-B port.

What you are looking for is a USB Accessory Charger Adapter, which exists in the USB spec but does not seem to actually exist in physical form.

No, what it is is a special USB OTG adapter that has three connectors, a micro USB plug to plug into the host device, a USB socket to plug in the peripheral device, and a micro USB socket to plug in a charger. It also supplies a special resistance on the ID pin to the host device to let it know that a charger is connected so the host does not supply a voltage on the VBUS. Without this special adapter with the ID pin resistance, the host will supply a voltage to power the peripheral which will not work with the charger on the VBUS. Thus this special adapter is needed. This is defined in the USB OTG and Battery Charging specs, but so far it doesn't seem like anyone is manufacturing such a thing.

Would anybody be able to help make a cable to allow this functionality? I have Muscular Dystrophy and want to use my HTC Evo 3D with the specialized HID USB mouse emulator that's integrated into my wheelchair. This is how I control my desktop PC.
Because I also use the mouse emulator and voice recognition the battery life of the phone isn't that great. I would like to power the phone with a cigarette lighter adapter plugged into my chair.
Thanks!
IT doesnt work on HTC phones. I tried a gew hours ago, since nkbody knew i was forced to buy myself a usb otg cable. Plugged it in the Sensation, and a logitech G35 on the other side. no result, tried with regular usb stick still no result

I'll try to do some research and tests and try to make something to help you and other people with similar needs!
I can mount ntfs with "USB Host Controller v0.44" app and 3.0.8-franco.Kernel R140 kernel.

Has anyone ever made a dual-end flashdrive for this thing?

With the S2 and USB OTG it seems like no matter what you do you'll end up adding significant bulk to the device. My main use for USB OTG is to plug in external storage and use that as a connection between computer and device rather than actually connecting directly. Video in particular is nice to be able to do that way.
My thought is to simply skip the biggest part of the USB OTG cable - the USB end - and hook it up directly to a flash drive. One of these cables with the female full size USB end cut off and the wires connected directly to the USB pins of something like this without actually blocking the USB connector. I split open a similarly sized USB microSD reader I have, removed the metal from the connector etc and was left with just the card and main PCB. Worked perfectly on my Galaxy Tab through USB OTG without the added bulk, and there was enough room to solder wires to the back of the pins and still have it reach far enough into a USB port.

Hooking these up directly would leave you with something like this sketch:

With or without the metal part of the USB connector still intact. The purpose would be to have a as small as possible thingamajig that could both plug into a computer to transfer content onto the thing and hook up directly to the S2. This way you eliminate all those steps in between with female and male usb connectors quadrupling the size of the package.
As long as you don't connect both ends at the same time there's no reason I know of not to just connect it all together like this.
The question I have is this...has anyone made something similar? Would be nice to see how well it works, any particular drives to use etc.
Decided to make a prototype for my Galaxy Tab, since I have spare cheap OTG adapters for it. Still waiting for some for the S2. The concept works 100%; works in 30 pin mode, USB mode on the Tab, and USB mode on a PC
So u just want a micro usb flash drive small enough to carry around just to transfer files from phone to pc, a solution to avoid any wires and "big" flash drives.
If this is the case, it just software solutions u need.
I use file expert from market.
It has a feature to share ur phone's files to its local network via wifi. Ur phone acts like an ftp file server so u can access ur phone files from ur pc.
If ur pc doesn't have any wireless network card, just buy a one, or use a wlan usb dongle. I'm sure its much cheaper than buying all those small memory cards and otg connectors and much less work.
No... I want a flashdrive I can throw a bunch of video on before I head out the door, with as little time spent transferring and looking for cables as possible
wouldn't it be the same (much easier and without the cables) as copying files via wlan directly to ur phone instead of copying it to a flash drive then copying it to the phone?
No, because copying over wlan is slow, and I'm not copying anything from the drive to the phone, just read files directly off it. If you have a nice class 10 microSDHC card in an adapter you get at least 10MB/s write speed, and you can fill a card full without it taking up space on your actual device
Might this be what interests you?

Basically, it's a microsd card inside a very tiny card reader plugged into a one piece usb otg adapter. it's as big as a flash drive and it can handle a 32gig micro sd.

I have one of those small sd card readers. very compact and might be what ur looking for
That card reader is not what im looking for as i have several, it is pictured in the second post as part of my prototype. It would be a part o the package, but not the entire deal. Need a smaller, angled otg piece than whats in that link. Which ill make, either as a one piece solution or with a female usb connector in between. Im just surprised that with hundreds of thousands of people spending so much energy on changing the color of a status bar, no one has bothered spending 15 minutes with a soldering iron to make an otg piece that doest stick straight out in the most awkward, fragile position there is
I found something very VERY close to what you were looking for:

It's angled, full USB female, but mini usb male, not micro.

That's exactly the kind of system I was thinking, either with or without the female USB (alternative being soldering the flash drive directly, but probably not worth the hassle). Having the adapter flush down the bottom side of the S2 would make for such a much more handy package and help prevent connector damage

[Q] Traveling with the Tablet

Hi All,
I have been using my new 10.1 Note 2014 Edition for the last 5 days, and I have to say that I am very impressed. I will be traveling extensively over the next several months and bought the tablet to use as somewhat of a laptop substitute. I wanted to know if anyone could recommend specific applications/accessories specifically for this tablet related to travel. I also wanted to max out the internal storage, but it looks like 64GB microSD cards are the highest available on the market. As far as accessories, I am looking for a very durable case (like Otterbox), and SD card reader for my digital camera, and a bluetooth keyboard. Thank you for any and all suggestions.
Best,

Depending on how much you like the writing with the stylus or the onscreen keyboard, you may want to pick up a bluetooth keyboard. Given that (to the best of my knowledge) there aren't any otterbox-ish cases yet available for this tablet, you could use the keyboard solution as a compromise by buying one of the cases with a built-in keyboard that helps to protect the device more than the average flip cover or sleeve. Don't know what kind of camera you have, but if it can take an Eye-Fi SD card, that may be a better solution for you while traveling. I have the Eye-Fi Pro X2 model, which although I really like it and it works well, it can be a lot more difficult to configure. The Eye-Fi Mobi cards are really easy to configure and (again depending on what camera you own) works really well with this tablet. FYI, you don't have to always have the Eye-Fi card actively transferring pics to the tablet...all you have to do is login to the app whenever you want to transfer pics or logout when you don't. Since the MicroSD slot is easily accessible, you want to get more than just one.

I fly a lot so needed a hard travel case for when its in my bag or suitcase, since I couldnt find any for our tablet I bought one for the Tab 3 10.1, The dimensions of our Note and the Tab are pretty much the same so hopefully it should fit alright, I should have it by the end of this week and will let you know if its any good.

For attachment of USB peripherals like a SD/flash/multi card reader, try getting a USB OTG cable for attachment to the Note's micro USB slot, and then the USB card reader of your choice.

I can confirm this works well fort me, the tablet's USB port doesn't give out enough power to drive a portable hard drive on its own, but it's fine for the USB memory sticks that I've tried and it also works well with my cheapy card reader. If you're going to use a card formatted with NTFS then I recommend installing 'Paragon exFAT, NTFS & HFS+' (free from Market), this works for my NTFS formatted USB sticks. The OTG adapter can also be used for attaching a standard USB keyboard which will be far more reliable than Bluetooth as it currently stands.
OTG adapters can be picked-up from the usual sources for a couple of £/$s, I suggest you get one with a right-angled connector to make life a little easier.
you should also get the Samsung spare battery pack. It's very compact and works very well.
I just picked up a small backpack from Walmart. It has a sleeve for a tablet inside, and 2 pouches for extra stuff on the outside (charger, flash drives, ect) so far, it is working good for me. The brand is Solo, and it cost me $20.

How can you can disagree with something you've not tried? It's better to give no advice than bad advice.
NTFS cannot be read natively by most Android devices including the Note 10.1, you will need a suitable mounter app or a modified kernel.

i was not talking about ntfs format but the power to make the external hdd works; i know that NTFS is not supported natively...

and maybe this tablet too... we just need to wait...

I think that the cause is lack of voltage. With a pen or sd card with adapter, works without problems. Even my camera gives to connect. Always with the OTG cable, of course!

That's a shame. Might need to pick myself up a cheap laptop (maybe one of these lenovo flexs') or a wireless hard drive, now in theory the wireless hard drives are powered so, if it is a voltage problem it might work without activating the wireless function.
Just weird that it would work fine on my nexus 5 but not on the tablet. No solid hdd light when plugged into the gpad.
What file system are you using on the HDD?

In my case, the formats are FAT32, I know that android does not support NTFS.

I'm waiting on my powered OTG to turn up and test (another member in a different forum had suggested they had an external working with the cable). Otherwise i might look at getting something different as i am going away for a while and want to use an external to store my movies.

as long as it is formatted to FAT32 (using stock ROM). Also using the powered OTG cable.

Ah cool, i'll hold on a few more days for this powered one to turn up.
I think it would work if you used USB 2.0 A Male plug to 2 dual USB A Female jack Y splitter Hub adapter Cable, the W male in charger, the two one on the hdd and the other in the Pad, i will try it very soon as soon as i get back to my house...
i also going to use usb extension cable coz the charger is way too long...
Have you tried it with a powered USB hub? Seems like that would address the power issue.

Hi,
Got my cable today (http://www.amazon.co.uk/gp/product/B00B5T4A60/ref=oh_aui_detailpage_o01_s00?ie=UTF8&psc=1)
Works a treat. The cable doesn't charge the tablet unfortunately whilst its reading from the drive, but at least i can see my hdd now.
I also tested it using an anker Astro3 and it works fine.
Good result, enjoy your movies .

Gents.
Use this program and you are able to go for 1TB disks and NTFS support on the fly.
Could play MKV movies >4Gig and scroll pictures.
Everything works fine for me.

Nexus 2013 Timur's kernal and 4port USB hub slow charging

Hello, so I have always had this problem of my phone charging so slow while using the 4 port USB I have installed in my car.
Here is the Hub I have: 4 port usb hub: StarTech.com Mountable 4 Port Rugged Industrial USB Hub (ST4200USBM)
I have used my Nexus 7 (2013) for GPS and if using it for long period of time I have noticed that the battery will actually go low even with it constantly charging while driving.
Here is the Cigarette Lighter car charger that I use: PowerGen® 4.2Amps / 20W Dual USB Car charger Designed for Apple and Android Devices - Black
I have it just plugged straight into the cigarette lighter with the USB cable going into the NA (Not Apple) port.
(A note, I had to use a USB extension cable to get the USB cable to reach the OTG cable.)
AmazonBasics USB 2.0 Extension Cable - A-Male to A-Female - 3.3 Feet (1 Meters)
Now I have the USB Hub wired from the 12V cigarette lighter, and I use 3 USB ports from it to either Charge 1 or 2 phones, and then have a USB Drive in the other so I can play music, watch a movie etc on the Tablet.
I went with the powered 4 port USB HUB so I could charge my phone(s) while driving but it is basically worthless for doing that I don't understand why. On my commute home which is almost an hour drive My phone will barely charge 10-15% no matter what level I started charging it at.
The Nexus 7 tablet will usually stay full charged if just doing normal stuff like playing music, surfing the net. But if I use heavy power program like GPS or Play a movie it will drop and it will say Charging but it will get low until I stop those programs and let charge back up.
I am using the latest version of Timur's kernel.
My concern is, I plan on driving a long distance in a month and would like to not have to worry about my GPS killing my Tablet Battery and getting stuck, and would like to be able to power up the Cell Phones so not having to stop at some store etc to try and find a charging station.
Thanks for your time. I am pretty open as to what I can do, so if you guys have tried and true solutions please let me know.
If you need to know my vehicle it is a 1998 Mitsubishi Eclipse GSX.
So...why not get a 4 port USB charger that actually delivers 2.4A to each individual port instead of trying to charge 3 devices off of a single 2.4A port?
Well I guess I thought this USB Hub was supposed to supply enough power to all ports.
I need the hub to be able to charge my devices as well as pass data to and from the Nexus 7.
This hub will allow for data exchange like I want, but has issues charging.
Is there a USB HUB that you would recommend?
I was hoping to achieve the same thing as you. I have a 3amp buck converter hooked up to my USB hub that I was hoping to charge my phone with through the hub.
The reason it won't work is because the data pins are not shorted so the phone will only charge at 500ma. Don't try shorting the data pins on the hub either because who knows what effect that could have on the hub.

Just wanted to check and see if anyone has found a good USB HUB that supports 2.4A to each port.
I'm sure other people have found some sort of solution to be able to charge their devices fast and use it for data to Nexus 7.
What ma are you pulling in pem ?
What otg cable ?
Right now i have a 7 port hub

Do you mean your nexus 7? I was having some issues with it staying full powered I recently switched out the Cigarette lighter charger for it and havent had any issues with the Nexus staying charged.
Now I just want to figure out how to charge my devices through the HUB and be able to do data transfer at same time.
My hub is powered from 12v source wired directly to it.
Data transfer from a hard drive ?
Your tablet should charge and use devices at the same time ....

Timur's kernel is important (otg+charge)!
I am looking for a hub that provides enough power to the USB ports to be able to charge more than just the tablet.
Example 2 people in car. Both need to charge their phone. Both plug into hub both get 2.1amps, AND 1 wants to play music from phone to car tablet. Should be able to do all from 1 plug, charge at 2.1 and play music from phone.
THis is the hub that I am thinking of but it only supplies 900mA. This is not enough to charge phone.
StarTech.com Mountable 4 Port Rugged Industrial SuperSpeed USB 3.0 Hub (ST4300USBM)
Does anyone have a better hub? Or some other method that I can do to get the 2.1 amps to each port, and be able to still transfer data over that hub?
Shoot worse case I am even willing to have a hub that has the 2.1amp for a couple of ports, and the rest are the 900mA. That way at least people not trying to stream can still get their phone charged quickly.
I don't know the method to go from a regular DC power cord to a car power but I will follow instructions if anyone has some.
Thanks. I am sure I am not the only person that is interested in this.
