Battery Charging with Red X?

I have just got my p6200 3g from malaysia. Couldnt be more satisfied. I feel like I just opened the only present I wanted on Christmas morning and its better than I hoped. Of course this came with an international gigantic 3 pronged charger adapter. I have (2) 2amp 5 volt adapters I was using for my dell streak 7. I tried them both and still get the red X. However when powered off, the device shows the battery charging animation. In settings menu it says battery state..discharging. I have ordered one from amazon due any day now, supposedly works with all versions of gtabs including 7.0+. Am I getting a trickle charge or is this due to not being a samsung charger? Im using the supplied samsung cable and outlet is capable of 2amps 5 volts.. please help! thank you!
the big 3 prong plug says 2.5 amp 250V? come on this thing cant need all that.. what does this batt need to charge??
##nevermind, I have the charger, just need the 2 prong USA adapter, hopefully I can find one. anyone have any ideas?

The red X is indeed due to not being a Samsung charger. Samsung tablets look for D+ and D- to be tied together and floating at around 1.2 volts or so. If they see anything else (such as the voltages that iPad chargers put on D+ and D-), they'll assume a USB connection and not charge.

Ebay is your best choice for these type of things :

just ran out, tried one at verizon, generic for galaxy tabs and worked... it says 2a 5v, just like my other 2, but those dont work.. im confused.. anyway I got a charger and Im stoked. Verizon guy asked me if he could "hold" it.

To my knowledge, all Galaxy Tab variants use the same method of signaling a "dumb" charger. So any Samsung charger intended for a Tab should work - see my previous post for details.

thanks a lot dude. excellent.

Or get one of these

Plug it between the cable & any aftermarket usb charger, even the ipad ones, viola normal charging. Can even plug it into the computer for normal charging just a bit slower

hi,
i have the p6200 version of the galaxy tab plus, came with a usb cable and an outlet charger that connects to usb cable. when charging on outlet, it charges fine, but when i connect the tablet to my sony laptop, it says MTP instead of USB connection and there is a red X on the battery icon of my tablet, it's also not charging. how do i get my p6200 to charge on usb connected to my laptop? thanks!

I could be wrong, but i don't think it will charge via laptop usb.

It will and does. I've done it, it just charges MUCH slower and if you use it while plugged in too much it will drain at a slower rate than if you didn't have it plugged in. I was backing up my tab and the battery was at 50%, I plugged it into my computer and by the time the backup was done (nearly 16GB full) it was at 70% (took 2 hours)

Buy one of these: http://www.dealextreme.com/p/usb-data-charging-extension-cable-for-samsung-p1000-black-91141
Set it to charge mode, plug between cable and charger (be it a computer or an otherwise not supported USB charger) and it will charge

Charging with a red X and media playback

My Galaxy tab 2 (GT-P1000) will not charge while it is on. I get the same charging icon with the red X. I am using the original cord that came with the tablet. Only when I turn off the tablet will it charge on the cord. The USB still works fine for connection to Kies. I just can't charge it normally. Any suggestions.
Also, I have been unable to sync my tablet so that my music, video, and pictures are available through the "video" and "music" icons on the desktop. I can play the files individually, but haven't been able to add them to the right library for these media players. What am I doing wrong? LOL

I believe you are asking in the wrong forum. This is the Galaxy Tab 7.0plus (GT-P62XX) area. You should ask in the GT2 section or the original GT forum (the model number you posted is the first Galaxy Tab). The fact that you have the product naming mixed up tells me you may have reading comprehension problems
Anyway. You are not being descriptive enough of your issue with usb charging. Are you using the Tab's charger? If not, it will charge really slow if at all (you didn't read this thread at all, did you?).
Also, You can't (AFAIK) play files directly off your Tab connected to a computer via MTP. It would have to be mounted as an external drive for the computer to use it as such.

[Q]Charging using USB

When I connect my P6200 using usb, it doesn't charge, instead, there is an 'x' symbol at the battery. Is this normal? Because using my Galaxy Ace, it charges when usb is connected. I'm asking this because I'm trying usb tether for the first time, but in this case if it doesn't charge, it means that I can only usb tether until my battery has depleted and I would have to recharge again to be able to tether.

Yup. Usb is not able to charge tab and ipad. Need to plug to wall for charging

Actually it does charge. More of a trickle charge tho. If the screen is off, then it will trickle charge a bit faster.

If the tab is connected via USB, will it at least be able to sustain itself via the USB power?
So if your battery is on 50%, and you keep the tablet on and are using it. Will it at least stay on 50% and not decrease slowly?

Samsung puts a resistor in their chargers so the tablet can distinguish between a Samsung brand charger and all other chargers.
The tablet will not charge (or use power from) any USB port except the wall adapter. (lame Samsung... really lame...)
You can buy adapters (or make them)
There's more info for creating an adapter yourself in this thread http://forum.xda-developers.com/showthread.php?t=845844

Just like the GT-P1000, P6200 is charging over the usb port of any pc, only when it is turned off. But anyway the charging process is much longer. Very useful when you don't heave the travel adapter with you.

i use this usb cable it work

It pulls a Max of 500mA from the USB or unknown charger. This will charge a tab plus with the screen off that isn't doing much. It will pull 1500mA from the Samsung wall charger.

My Plus charges normally from PC via USB. Icon shows 'x', but still in charging process anyway. It takes longer time but for those who tether should be ok and Plus should stay at least on the same level of %. I have unoriginal cable bought together with car charger.

I purchased a micro USB charger adapter from ebay. It just plugs into the 30 pin port and I am able to use my cell phone charger with no problem at all. The cell charger puts out 1000ma and the tab plus recognizes it. Do a search for P6200 Micro USB Charger Adapter on ebay.
If you are determined to use a computer to charge the tab plus, you will need the adapter above and a dual USB A to micro USB B Y cable. It will plug into two USB ports on the computer and give you the 1000ma to charge the tab plus. This is the best solution without having power cables all over your desk.

re
HEllo, where can I buy this cable?
thanks

Yesterday I bought P6200 without charger, was using usb cable and it ws slow.
First I thought there might be some problems but this post helped me figure the cause

[Q]Help please!!! Battery don't want to charge.

Hi guys...my friend gave me his Tab 2 7.0 in order to root and flash paranoid android on it...but now something terrible happens it won't charge...but it recognizes if it is plugged in or not...of it is off and I plug in the USB cable it loads the battery sign and shows me a battery with golden "juice" but than the sing disappears again...could you help me please? I read on a lot of forums that it's might just the cable but I can't test...he gave me just the USB cable... One thing I recognized is the phone showed me before rooting a litte red "x" in the battery all the time I was charging.
I'd be pleased to all answers.
EDIT: I've just cleaned the usb cable and the female input and actually it charges but it doesnt show not even on cm10.1.2 stable.

Did you try using another cable? Samsung stock cables are the worst. Most of the problems with my galaxt tab 2 and my girlfriend's s3 were caused by the faulty cable.
Just make sure there is nothing wrong with the cable or adapter you are using then go from there if it still won't charge.

[Q] USB charging of WiFi model

I tried the cord that came with the tablet, and my other USB cables - same results with all. My Note Pro won't charge via USB at all - when I plug it in battery status says "not charging" and it keeps discharging, while idling with screen off. Only AC adapter works and battery status changes to "charging". Any ideas?

You can't charge the tablet off s usb port. Draws too much current. Some motherboards have an option to turn on a special charging function for a usb port, but if you had that you would probably know.
Your stuck with the wall charger.

Stock kernel on the Xperia Tab Z must have USB charging enabled. This is an exception rather than a norm I would think, with OEMs probably choosing to disable this as a safety measure (or so i've read).
Until a custom kernel is developed for the Note Pro we'll probably not see charging over USB.

The problem is still the max output from the USB port, which is 5V 0.5A , you'll notice that the charger for the this tablet is 5.3V 2A.
I'm an electrical engineer not a computer engineer, so I'm not sure how a kernel would change the max output current supplied by the PC. This has actually piqued my interest, I'm going to do some tests and see how much current the port can push. I'm betting the data lines on the plug send some information about what's being charged.
Maybe I'll build an adapter that that let's the tab pull a full 2A from the port.

Does it make a difference if it's USB 2.0 or USB 3.0 port?

Normal USB 2.0 is 500mv, USB 3.0 is 900mv. Some motherboards can push this up to 2000mv, usually a red usb port

The nature of my kernel comment stems from my Nexus 4 experience with a custom kernel which has a setting to enable usb fast charge (Franco kernel with his FKU application).

This review says Note Pro 12.2 can be charged via USB - it's just slow. As I mentioned in the OP - when I plug it in via USB cable the battery status says "not charging" - could it be it's actually charging, but due to low current the device itself doesn't recognize it's being charged?

Just plug it in for a few hours and see if it increased your battery level... done.

It kinda works - with tablet completely idle and screen off it charged about 4% in 1.5 hours via USB 3.0....don't think that's helpful to anybody. Hopefully, someone finds a way to push more current through USB 3.0 port. Would be nice to eliminate the need to use AC charger.

I had mine hooked up to my laptop (Asus N76VB), it didn't charge according to the indicators (neither do my TabPro 8.4, Tab 3 and Tab 2, nor my TF700T), but the battery didn't drain either while I was using it. It stayed at 56% for 5 hours whilst browsing, which it really wouldn't do normally. USB 3.0, no additional settings enabled on the laptop, all Sync and GPS turned off on the tablet.
My TF700T literally said in the manual: "Charging from USB can only be done with the device turned off." I'm sure that applies to these tablets as well.
On the upside, my 15600mAh aSolar powerpack charges the device! :victory: (It can't charge my Tab 2 or TF700). I'm really, really pleased about that!

Galaxy s5 2.1A car charger not working

I recently got a new Galaxy s5 on contract. I've heard that the galaxy s5 supports fast charging with a 2.1A charger. I bought a 2.1A car charger online, but the charger doesn't work when I connect it via a regular micro-USB cable to my phone. My brother's Galaxy s4 mini charges fine on it.
I was reading something on another post mentioning the need to modify the cable itself?
Any suggestions? I have another USB car charger for an iPad, and this charger also doesn't seem to work, whereas my old 1A car charger does work, but charges very slowly.

I havent tested with my Galaxy S5, but previously I had "noname" chargers and cables, and they worked fine with my HTC One S, but didnt work with my GF's Galaxy S3.
Samsung might have made devices more "sensetive" to crap products. Try different cable (try original USB cable that came with ur phone and the charger you bought).

I tried original USB but to no avail. Perhaps this has something to do with this:

The problem is most generic car chargers are designed to work with Apple products. Apple uses a non-standard way of telling their devices essentially "hey, I'm a charger." This makes "standard" devices not recognize the charger properly. The device tends to think it's plugged into a computer and only draw around 500mAh.
You can convert a USB cable into a charging cable by shorting the data pins (on the device side), or you can buy charging only cables. I've been using these cables on my S2, and now my S5: http://amzn.com/B007F1DV76 . I used a Galaxy Charging app to verify charging rate and it indicated 1.2A on both the Samsung wall-wart and cable as well as my Scosche 2.1A car charger w/ charging only cable.

Why is this? When 4 out of 5 devices are built on Android? http://tinyurl.com/qxpnyoh
I am so irritated at not having access to quality accessories for my devices. Take for example I wanted a set of great sounding headphones that controlled my mic, my tracks, etc. But, you won't find it other than Samsung's own that come with the phone. I had a great sounding pair of Seinnheisers but could not go back and forward on tracks. I plugged it into my ancient Ipod 5th gen classic and worked beautifully! For $80 I should get full functionality for my S4 or S5! My only choice is the LG Tones. Which are awesome but if my battery dies then no music or calls for me!
Frustrated!

My Klipsch earphones work perfectly changing tracks with with the inline remote.
Also my 2.1A charging won't charge my GS5 but it'll charge a GS4 and my Galaxy Exhilarate.

Anyone wanting to know how to fast charge using the usb port on your pc/laptop?
This usually takes ages compared to charging via mains lead, the hack itself is quite simple and involves modifying the usb cable
my results are as follows (these can vary depending on what you are using your phone for, what background apps running, etc.
charging with mains lead :
4.2v
998mah
mains ac
charging with STANDARD usb lead:
422mah
3.999v
standard usb
and finally the MODIFIED usb lead hack:
4.161v
782mah
usb hack
as you can see it is a 53% increase in charging compared to standard usb charging mah, and slightly under mains ac charging mah,
as my phone is always plugged in at my work pc or home pc or laptop or whatever this works out good
TUT:
use at your own risk this is for information purposes only and I hold no responsibility to any damage that may arise
using a micro usb cable (charging cable for htc phones)
cut it using a pliers half way through the cable
using pliers again cut away the thick black wiring, the red and black small wiring, and white and green wiring
from the usb port end to the microusb connect the black and red cables together so they join
from the microusb end short out the white and green cables together
from the usb port end leave the white and green cables, do not touch these
use insulation tape/solder to clean it up and then your cable is ready
I will make a mod for car chargers also soon
see attached image showing which wires to cut and which to join up and which to leave alone, if this helped you in anyway (it should help you ) then please hit the thanks button
this mod will trick your pc/laptop/htc into thinking that it is not a pc usb cable and will allow higher currents and voltage to your phone
you can check this with current widget from market place
once this mod is done, you cannot use the same cable again for pc/usb tethering or usb disk drive, only cable can be used for charging

I also bought a charger (Rapid USB Car Charger, http://bit.ly/VrK8s2) that was able to charge up to 2.1 A, but when I connect my Nexus 5 (with OEM cable), I charge with speed of 500 mA. I expected least 1 A.
I'm not amused at all! End users shouldn't have to deal with this nonsense. This should work out of the box!
I have two alternative:
1. Buy this charging cable.
2. Change kernel to trick the phone to draw more power from the USB port.

wtf black price!! lol. mine was about $10, purchased 2 when the s5 phones came out.

I heard that cables matter the most in charging. I always use cables that came with my phone and have had no issues charging my phone so far. Have used PowerGen and Avantek. Both charge my iPhone 5 and Samsung Galaxy S4 at full speed. High quality construction and seems pretty durable.

This car charger works flawlessly at 1800mAh, i have been using it for a few month now.

I tried at least 5 different chargers and none of them charged more then 450mAh, i was really depressed about it until i found the charger linked above. Also, the fast charging USB cable *charges on 750 - 850 mAh which is just enough to not let your phone loose battery percentage while the navigation is turned on.
