OTG cable for external HD and charging.. a simple noob way? - Nexus 7 Q&A, Help & Troubleshooting

Hi,
I have read an awful lot of threads regarding this topic but have become more and more confused I have a Nexus 7 3G and have the tablet mounted in my car with a Samsung S3 1TB portable drive using stickmount playing music through Poweramp which is all working beautifully until the battery runs flat. I have unlocked and rooted the tablet using the wugs toolkit and nothing more. I do not know what a kernel really is and people are talking about different kernels and roms to enable charging with a y shaped otg cable but am completely confused by this. Can someone please help me out with a simple explanation on how to do this please? and also anyone know where in the UK I would be able to buy one of these cables? and lastly I have a 2amp use charger through the cars 12v cigarette lighter that I would like to use to charge in this setup...would that be enough or would I have to get a mains inverter? Many thanks for reading...

Anyone?

[Q] does the N10 have separate micro USB and charging port?

Does it charge with Micro USB? Or is there separate charger that would allow for simultaneous OTG & charging? If so, is it a samsung proprietary cable?
one port. I don't see why people are all upset with a tablet having one micro-USB port? What I would do to have micro USB on my Asus transformer prime, so damn annoying!
ANd plugging into a PC will charge slowly for most phones, and it depends on tablets, some do some don't. Even then, who leaves their tablet plugged into their PC all day anyways, a big no-no for phones as we all already know, won't charge very quickly...
Are the pogo pins not for charging?

They can charge as well when the tablet is in a dock (if that ever happens...). The pogo pins are not the primary charging method when not in a dock.

ah.. well for one thing, I would say the primary reason is the one I just stated: simultaneous OTG + charging.
There are users out there that do not like the limitation of having no MicroSD card.. The closest thing, without microSD, is OTG. But the problem is that you cannot constantly use it or the battery will empty [also using battery cycles, that could have otherwise been avoided, and saved for when you really need them].
So may I ask where you got this conclusion? I would like to show it to someone.
Would a usb splitter work if you wanted the device to have two ports? Just a thought.

No, you'd be trying to charge the device, while it is giving out power on the same wires, to the USB OTG device.
The only way to fix it is with a kernel patch to disable outgoing power, and accept a charge with OTG.
Can't you buy an charger that fits the pogo pins. Not from google, of course.

maybe..but on the Nexus 7, when you plugged in OTG storage, it would not charge with the pogo pins--at least I'm pretty sure I read this on xda.
so it might be like this on the Nexus 10 too, I dunno.. I guess we'll find out soon.

No, I meant, you asked why people were upset it just had one micro usb port [instead of--I assume--a charging port, and then an additional micro usb], and I said it is [at least for me] because it makes it harder to properly use external storage [that's needed for some people because of the lack of micro sd].
is there an official spec sheet that shows it charges via its only micro usb port?
Hi everyone, I was wondering what type of micro usb port was on the Nexus 10, I cant seem to find any close up photos, I am a noob when it comes to tablet and smartphones, but after looking around for OTG cables and such for my futur N10, I came accros micro usb type A which is bigger and thicker, and micro usb type B which is nice and thin, so I'm kind of confused, which type do I need for N10, can anyone fill me in?
Sorry if I posted this in the wrong thread, but it would probably of been silly to start one for such an easy question . ^^

Sorry, but then buy a tablet that has a MicroSD. The Nexus series doesn't have MicroSD. If you don't like that, there are other options.

Nexus 10 Charging Cable

Hi guys,
Is the data cable included with the N10 the same as all other micro usb data cables?
Can I purchase a data cable off ebay and it work the same as oem or do I need a specific kind/brand?
Does anyone have a link to a "good" cable?
Lastly, I just ordered this thing, should I be OK using it?
http://www.ebay.com/itm/200847761697?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649
I don't want to gain charge time as this thing takes forever to charge.
i have many micro-usb charging cables and have yet to find a bad one. I have some from HTC, HP, Samsung and Nokia.
AAAlan
After some research it seems as if the N10 cable is USB 2.0 which explains why it looks different than my wife's Mytouch 4g cable.
Nexus 10 will charge off any usb cable I guess. You might not be able to transfer data using a usb first gen cable, and the charging rates might differ, but you can use any OK looking usb cable.
Of course if the cable is something out of the jurassic era plus chewed off by rats it might not work.

Galaxy S4 and the MHL adapter

Hi everyone, some of you may remember that the S3 had to be connected to the charger to output via HDMI using the MHL adapter. I just did a quick test using the S4 and the same adapter and good news! It now works without a charger! If you're interested in seeing it in action take a look at the video.
Thanks for sharing!

Do you think the S4 will work with any generic MHL adapter? Does Samsung use anything proprietary?
While it is backwards compatible, the s4 supports MHL 2.0 (i.e. it has a new adapter that does not require external power). You can use the old one, however.

I just read the newer Samsung devices use 11 pins. I don't have a samsung device so I cannot test to see if it works on the 4S. Where are the pins? I'm assuming the 11 pins are on the male usb connector. Can someone please verify this. It would be great if someone could find or take a picture of what the pin setup looks like so I can tell if it is compatible. My eyes are not the best right now, (missing contacts) so its hard for me to count the pins.
I'm guessing it's proprietary

The S4 HDMI output is looking better as I do more tests. Previously the S3 couldn't send sound to my Philips TV (sound worked fine on my Samsung TV) now using the S4 the sound works! Also I'm happy to report that everything (web browsing etc.) is coming across to the TV in 1080p.
Also when playing a video on the TV you can use the S4 to do other stuff.

After some testing I have found that in order to charge the phone through the MHL adapter you must:
1) Plug the charger into the wall socket.
2) Plug the charger into the MHL adapter.
3) Plug the MHL adapter into the phone. Phone should start charging.
4) Plug HDMI cable into MHL adapter.
I've tried plugging the adapter/charger/phone in different ways and the above way was the only consistent method to get the phone to charge and output to HDMI.
I hope this is just a software issue and can be fixed, it is a bit annoying to have to plug everything in a specific order.

Hello!
I curently have the Galaxy S4 i9500 with the S3 MHL adapter and I confirm that it does not require anymore the charger, but yes it seems to be a specific order to plug everything as sometimes it did not charge for me.
I have a question: Is the S3 MHL adapter able to charge the phone via HDMI or do we need to buy the last S4 MHL 2.0 adapter? Does not work for me but maybe my TV does not support this (quite old, about 4 years).
I don't think you can charge via HDMI regardless of which adapter you have. If you want to charge you need to plug in the charger.
Greaaaat! Thanks for the video!!

HDMI charging is possible only with the original S4 adapter, it also supports 60fps... BUT, in order to recharge, the adapter must be connected to an MHL ready TV, otherwise it won't charge!

Thanks. But chargers are easy to find. What is difficult to find is a USB cable to work. You'll see in the thread I linked on the first post, lots of people are having challenges with finding USB cables to work even if a charger is well above 2 amps. Even using the stock LG charger, no USB cables seem to work except the one that came with the phone, to eliminate the "slow charge" icon and allow around 1500mA of current to be drawn from the charger like it should in a fast charge..
what cable are you using with your new charger? And do you get the slow charging icon?
I think it all boils down to the charging base... I have used the LG, various Htc and Samsung base units with all kinds of mini & micro USB cables without any issues... The base units are rated from 800mA~1.5 and have not had any slow charging issues... I've only experienced the slow charging when connected to the PC or some car chargers...

I used to run a 1.5' usb cable from monoprice and the GPS on my phone would discharge the battery faster than it could be charged. Now the phone charges so much faster.
I have yet to have a problem with any of the generic monoprice cables and wall charges I bought a couple years ago. Only time I get a slow charge notification is using my 1a car charger. My Optimus G and HTC One X chargers and cable work fine as well.
IT IS NOT THE CHARGER!!
It is something in the cable. And good luck finding one. If you use the included USB cable that came with the G2, then it will charge on ANY charger "normally" (fast charge). If you use ANY OTHER cable, it will slow charge.
I don't know what is in the cable or why it makes a difference, but none of my USB cords/chargers work unless I use the INCLUDED USB CABLE.
I had a thread on this already somewhere in the General Area I think. It REALLY sucks because I have TONS of chargers and cables. I have some at work, home office, bedside, 2 in my car, friends cars, etc. I DO use Wireless Charging at night and luckily the phone has a huge battery to last through the day.
There IS a problem here but my thread got ignored like, "I don't see a problem here, just use the included cable". Well yea if I stayed home all the time. My work makes me travel for work so I have to make sure I remove the 1 working cable and carry it with me EVERYWHERE. What a pain in the butt.
Has anyone tried on custom roms to see if perhaps it is something just on the stock software telling it to go Slo-Mo.
My Verizon non usb attachment cable charges fast. My OEM Spectrum cable does as well. My dual one amp car charger charges slow no matter the cable, and my works Motorola and Kyocera cable charges slow no matter the connection. I have a couple Samsung's I need to test. I do not own any generics. I have not tried other combos.

LG Spectrum cable does not work, slow charge, my fault.
However, the straight plug from my new Verizon car charger does work, the USB port also (ONLY with G2 cable so far[tested lg spectrum, Motorola, Samsung, and Kyocera. Older cables]).
Recap: So far ONLY Direct car charger or USB G2 cable has fast charged. Must be chipped or using some different wire combo?

Ok. I can confirm that the cable used for the Nexus 7 (2012) works.
Also, the original cable for the Samsung Skyrocket works.
Works meaning fast charge.
I can't gurantee that this is the cable, but my skyrocket cable does look like the top cable here:
http://www.ebay.com/bhp/samsung-galaxy-s-ii-skyrocket-usb-cable
(Charger looks like it too, but the charget won't fast charge G2)
Edit:
The Skyrocket was really picky about cables/chargers. If it didn't have the correct one, it would wakelock. Maybe there's something with the way it's wired that makes it good for the G2 as well.

Yeah, I'm not so sure about that. It may be the software in the phone that is causing the issue. I had to replace my car charger so I picked up a rocketfish 3.0 amp charger. When I originally used it, it was ridiculously fast, literally 30% in about 30 or so minutes.
Now, here's why I don't think it has anything to do with the charger cables. When I got my phone, I kept putting off doing the first update because I wasn't sure if I was going to root this phone. During this time, I got very good charging speeds from my rocketfish 3.0 amp car charger and many of my other rapid chargers. When I decided I wasn't going to root, I went ahead and downloaded the update. Now, unless I'm using the cable that came with the phone, I get the slow charging message with every single charger. I went from 30% in 30 to about 10% in 30 on my car charger.
I may need to pull out my tinfoil hat, but it would be a pretty huge coincidence that all my charging woes began with that update.
Yea something isn't right. I have a GNex, G2, Nexus 7 2012 and 2013. I always check for AC charging in Settings>Status. It will say AC or USB. When I got my Nexus 7s I replaced all of my chargers with fast chargers. For 2 years I've been fast charging. I got 3 different fast USB chargers on my desk, using the existing setup, Everything fast charges except the G2. If I use the included G2 cable, it will fast charge off all of them. The same with ALL of my home/office/car/travel chargers.
I can only get it to fast charge when I use the included USB cable.
Its something magical with that cable.

I haven't even unwrapped the charging base and usb cable that came with my G2, they still remain in the box. I have been using the charging bases from my Nexus 4, L9, Htc One X, Motorola Atrix and a GS3 through out my house and have mixed cables from god only knows where and all of them work. I get no slow charging from any combination. Even using mini usb cables with micro usb adapters attached and they all still work. I've checked all the output voltages and the lowest one is 800mA. Granted my D801 is rooted, but no custom rom as of yet.

Have you gotten an OTA update?
I'm on the Verizon model. The other guy here said he only started having problems after the Verizon OTA.
-sent from my LG G2 using XDA Premium 4
Here's my theory,
There are chips either in the battery, the transformer, or both. When the phone doesn't detect what's required, it gives a slow charge message and reduces the charge speed. I have had previous phones with batteries that had built in chips that I had to buy because the generic batteries without the chips wouldn't work as well. I haven't taken a good look at the battery, and the transformer seems abnormally large, when I get a chance and some spares, I'll probably take them apart.
My tinfoil hat is telling me that LG is trying to rope us into buying first-party accessories, but it may also be a way to regulate battery health. Having a non-removable battery, it may be a move by LG to extend the life of the battery as long as possible.
Also, I just rooted my phone and so far no change. I will try the car charger tomorrow.
No updates from Tmobile as of yet... I can only imagine the frustration though. You would think LG would have made charging the phone, regardless of the model more standard across the board.
Sent from my LG-D801 using xda app-developers app
800mA is a slow charge... You should average 1700mA. Our cable is five pinned (if that matters). I need grab the mA reader app again. Now we know there is kernel check for flux ect. I want to know if the cable is pre chipped as well for check and regulation, isn't too uncommon. I'm beginning to lean more on an over aggressive kernel check though or possibly a combo of kernel and certain chip model check. I just find it odd my straight Verizon car charger and only this cable is working for me. Gonna check car cable pins in the morning. Verizon here, OTA taken. Did not check before.

Charging slowly? Consider your cable.

I usually stick with the OEM charger and cable with devices but since the Shield K1 doesn't ship with either I was using another cable I had around.
I noticed the tablet was discharging while in use even on a 2A charger. I tested the charger's power consumption with a wattmeter and found it was only running about 1A. The cable was inadequate. Trying different cables was an illuminating experience.
I found some informative sites about this. Here are my favorites.

Those are some really informative links. Thanks for that.
Noticed that too! Bought some days ago an longer USB cable (3m) but used it with the original charger. During gaming battery drops, with original cable it doesn't load but also doesn't drop, strange....
yeah, also bought some generic cable (1.5m long) but im using the oem charger/adaptor of nvidia shield tablet, since i broke the tip (micro usb port) of the oem cable.. there is a noticeable slowness in charging.. so, with regards to charging time, it's not always the adaptor itself, you can also consider the cable..
I had similar experiences using other devices.
I recall reading recently that there are estimates that *more than* 50% of USB cable manufactuered in 2014 were fakes. The trend was not going down - who knows, it might be 60% in 2016 :|
I use the app ampere and tested all my cables and chargers and sound that some cables would max charge at 150ma, and others at 2000

Ampere doesn't work with the shield tablet.
I tested with the shield tablet k1, marshmallow update. Just always showed 0mah. I put up a review explaining it, but the developer simply flagged the device as incompatible rather than trying to fix it.
I have a usb detector device from amazon tho, and I get 1.2 to 1.8 amps with if I use my galaxy s5s charger. Oddly out of the 4 different ones i have, thats the fastest. I read it supports quick charge 2.0 so I gota fancy charger with that that does supports it, 2.1 amps.. But it actually charges much slower then the samsung one - Yet chargers my actual S5 at the same rate, so I just swapped the cables and leave it like that.
PS: Was charging MEGA SLOW no matter what before I did this fix:
chmod a-x logd in terminal emulator.
(This also greatly enhanced battery life)
Also charges much slower with screen on.

Actually, ampere is working with the second update for the k1. You can get it from the thread here at xda if he hasn't fixed it in the play store yet
