Hey guys,
So I made this rather funny discovery (not surprising though). I have an OTG cable for my Gnex to read USBs, out of curiosity, I plugged in my USB data cable for a Galaxy tab 7 (P1000).
Since this tablet doesn't really have USB host functionality (unless I have like 300 cables and a power source), my Gnex was charging my Gtab :\
If I were to get a new tablet (which I plan to later), could I choose which device to charge which device? Say e.g I want to charge my phone using my tablets power. I ask this since newer tablets have host functionality.
Thanks
Bwahahaha. I have visions of a short guy bringing a tall guy a ladder.

it's not going to work, you can't output power through MHL or host(im pretty sure) and besides the voltage would be to messed up to charge. so no.

OK.JPEG
I see your point, the charge provided by USB host wouldn't be that high anyway...
Would be a cool function to have though right? I've been caught in situations where I wish my tablet could charge my phone ...

Yes you can output current through OTG, so it is not a wonder that you can charge your tablet. Otherwise you could not even use any memory sticks and such.

Every night i charge my Galaxy Nexus using my Motorola Xoom.
I have my Xoom plugged into the wall charger --> my USB Host cable plugged into my Xoom --> my USB-MicroUSB cable plugged into my Galaxy Nexus.

Are you able to swap this?
I.e charge your Xoom with the gnex?

I doubt the GNex can output enough power to charge the huge tablet battery at anything but painfully slow 1% per hour process.

Moreover, the Xoom cannot be charged through USB...
But I like the idea to charge the GNex through the tablet. It's got quite a large battery. Two actually.

The other way around works just fine with my XOOM. My XOOM can charge my old N1 and my new GNEX just fine... XOOM has like 3 times the battery...
Seems like that any new tablet I get then would be able to charge my phone then
I won't be charging my tablet much, most likely tablet charging the phone e like you guys have mentioned!

I would like a longer cable that will also allow charging from computer USB, car charger USB port, etc...
Basically I don't want to be limited to having to have that brick of a Samsung wall charger with me, and of course the longer cable.
Can anyone recommend one? I've looked on Amazon but all the descriptions just aren't clear enough...
Unfortunately I have been reading that the "bulky" charger is the only one that will charge the tab properly. My suggestion would be to buy a USB extension cable to solve ur short cable issue.

Really? I swear I read of a cable that would work on computer USB.... darn, my cable is short circuiting at the 30 pin so I need a new one regardless. I have an extention cable already.

I leave my tab plugged in overnight to my pc using the supplied samsung usb data cable. It charges at a slower rate but is typically charging about 70% over a 9 hour period.
I also have an USB3.0 2.0m extension cable (tried an ASUS transformer for a week), which allows charging and data transfer ok

That will allow the Tab to charge from any 2A charger (most common would be iPad chargers).
The tab will go into USB charging mode (e.g. charging disabled) with iPad chargers unless you use the cable above or modify the charger.
I haven't had time to investigate, but it MIGHT be possible to allow charging from unmodified iPad chargers with a kernel modifications. Not sure - it depends on whether we have separate ADCs for USB D+ and D- or not.
this will work, you could also buy the cable without the charger.

Can't charge from PC, not enough current available. Best you can do is adapters like th DX one to allow iPad chargers which are often more compact.

Tab, not Tab 10.1 - The original 7" Tab will charge from a PC, the 10.1 will not.
The cable will work with the Tab 10.1 just like the 10.1's stock sync cable - which means it will transfer data but not charge when connected to a PC.
Guys, I keep reading in this thread that the tab 10.1 can't be charged via a PC, well I'm here to tell you it can and does. Every night I leave mine connected to my PC, and in the morning it's charged! Admittedly it's a slower charge rate (seems to be around 6 or 7% per hour), but it charges never the less. I use the samsung supplied cable and nothing else.
Of course, it won't charge if the tab is in use via a PC USB port...
The standard charger lead isn't long enough for my needs. I have a 1m USB extension lead, will this affect anything or should it perform the same if I extend the stock lead? What I am most concerned about is will it still have over charge protection or will the 1m a USB extension affect this somehow?
Also? I connected to my PC via USB and it started charging but much slower than mains, should that be the case?
Thanks.

Standard mini usb and usb doesn't provide the same power that the mains can, therefore doesn't charge the phone as quick.
What I meant was wall charger to USB extension to Samsung USB/micro USB charger lead to phone. Anyway, works perfectly. Will just keep checking to make sure it stops charging at 100% and doesn't blow up!

USB port pn your computer is only 500mA and your regular wall charger is around 700-1000mA (1A)

The overcharge protection and all charging/battery logic is handled by the phone. The charger just provides power. This is true for pretty much all phones and similar devices charging over USB released in the last few years.
If fast charge makes it charge faster then why wouldn't that be the default way to charge in a rom? What's the downside of using it?
Btw I just realized this isn't in right section, my bad. Move it if you'd like

Fast charge is used when you're charging from your PC's USB. This makes the charge time similar when charging from a power outlet. So essentially it only helps when charging from your computer by increasing charging speed.

When fast charge is in use, you won't be able to access your phone from the connected PC via the USB.
Sent from my Galaxy Nexus using Tapatalk 2
It's also nice when using a charger or cable the phone doesn't think can do >500mA. I have an old charger at work that is like that. Fast charge allows me to use the full capacity of the charger.
It's not the default because some computers behave badly with it and you can't do adb/media etc when it's enabled.
I love how my Nexus 7 is able to charge my phone very quickly. Do you use the N7 charger on your Gnex without problems?

your other thread you started asks about your phone smelling like burnt plastic. maybe you should use the charger it came with and see if it still does that
I don't use the N7 charger on my phone regularly. I used it last time I went on a trip because the original was at the house.
Sent from my Galaxy Nexus using xda premium
should be okay. your n7 charger provides more current than the standard gnex charger. the phone's charging circuitry will only draw in as much current as it can take without damaging itself.
ever single electronic device i own i charge with the charge with the charger they came with
I have random chargers laying around everywhere. At work I charge with my old Nokia n86 charger. All good. :thumbup:

I been using my old HTC charger for my galaxy nexus on an off for the last 12 months with no problem, I never heard of anyone damaging their phone using other phone chargers that fit, if you lose your charger an buy a generic charger they work the same way without needing one made by Samsung, I know most phone manuals will tell you to only use charger supplied with phone but they always says that an rather you get a replacement through them.I also use to lend my gnex charger to other people at work who owned HTC phones all the time an they have no problem with it.

The entire idea is to have the micro usb system universally, all manufacturers / os. Only apple messes it up.
I use the charger it came with and also several other generic ones (car, work, second office) and all seem to charge fine with no signs of excessive heat. What about charging time? I just came from the HTC Thunderbolt and would leave it charging over night. I thought I read that is not recommended to do with the Nexus. Does anyone leave theirs charging over night?

I plug my galaxy nexus in every night before I go to bed to charge overnight since I got it last December that way its fully charged an ready to go when I go to work every morning, I have done that with every phone I have owned , I don't see how that's a problem.
GNex ~ N7 charger :good:
N7 ~ GNex charger
MicroUSB plugs are universal so all should work fine. Only time it'd be bad is if the wiring in the outlet you plugged into is done improperly.
It should be fine, as someone else stated earlier, the N7 charger is capable of supplying more current, but in simple terms it's a "suck" rather than a "blow"
The devices will all have regulator circuitry in to prevent damage.
The other way around is tedious (charging the N7 from a GNex charger...zzz)
Kinda had a feeling to not use it as it's a higher voltage but it would charge my phone so much faster it felt like. Well now the phone will just reboot no matter what rom or stock rom I use. If it does get to boot up the screen starts flickering and you can tell something is wrong. It stays on fine in recovery or bootloader but nothing else. I can flash anything the problem is when it needs to boot up. It's very weird but sprint is sending another after they tried to tell me it's because it's rooted.
Wow good to know, almost used it last night to charge my gnex

Strange. I've used sooo many different chargers everywhere I go and never had a problem. If its micro USB, I use it.
I used the n7 charger one time and I swore I smelled burning plastic or something....never again will I use it on my gnex.

Errrr . . . I actually suspect you've just stuffed yourself up some other stupid way. (or the charger you used isn't actually a Nex7 charger)
The Nex7 charger is not higher voltage. It's 5v, just like the GNex expects. It's a 2.1amp charger, compared to a 1amp one for the GNex, but that's irrelevant, as chargers don't "push" current to a phone - they'll only give it what it asks for, so using a 2amp charger with a device that expects a charger of 5v, 1amp, is not a problem - it'll just give it the 1 amp.
Yes he's ^^^ exactly correct. The voltage is the only concern here.. and it's 5v like every other USB charger should be.

hmmmm I use my Nexus 7's charger with my GNex all the time... and no issues
The only issue I've had with the N7 charger is the USB cord end is too fat and messed up my old charging port otherwise it was fine for weeks

Did that same thing happens, maybe it is not the charger but pretty much it's something hardware no matter what software I load it reboots at random times and screen flickers. I was just using the phone one day and it rebooted and never stopped. Tried everything known to man to get this phone to work.
I also was using the nexus 7 charger for weeks and the only thing different was the usb cable is a blackberry but that should not matter.
I use my iPhone 5 charger
I use a kindle charger (and its long usb cable) to charge my gnex all the time.. and that thing is meant for all eink kindle models including the dx. No issues at all.
Have also used iPad charger, old gravity touch charger, iphone charger, 5v is 5v.. so don't really matter what charger you use .
I can confirm that I have used my n7 charger with an aftermarket cable/n7 cable/gnex cable about 20+ times n i never smelled any burning plastic/metal/rubber/carbon fiber. My gnex still performing exactly as b4, except the sucky 4.2 update, that is. That blows, big big time. I mean, i seriously had the desire to slam the damn thing in the wall so many times. But I digress.
Conclusion-Either I have a special super gnex, or n7 charger doesnt affect the gnex. charging speed=slighly increased though. slightly. like 15mins lesser.
I've used a nexus 7 charger with my gnex 50 times+, no issues.
I've had 3 Android devices and 3 chargers. I don't even know which is for which, but I've never had any problems with charging any device with any of the chargers.
Definitely no issues. I've been using Nexus 7 and Blackberry Playbook 2 ampere chargers without problem
