Charging Cable Recommendation

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.

Dude not to be rude but the Guy is looking for a cable that will charge his tab from his computer. That is the stock charger and cable that came with the tab. That one doesn't accomplish the task

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...

Charging... Taking forever...

Does anyone else have a problem with the S3 taking at least 8 hours for a full charge?

Mine charges fairly fast and takes around 3 hours. Are you using the stock charger that came in the box ? I find that charges fastest as its 1 amp. But my blackberry charger and other micro usb chargers take a lot longer including my car charger. Usb charging from pc will be slower too. If not using stock charger give it a try

Yes I do find my S3 taking a long time to charge. I am connect my phone to my computer USB, not sure if using the adapter to plug in a while would make any difference. I so notice the battery sometimes gets drained pretty fast, then other days the it is pretty good.

Thanks guys, yeah I use my stock charger but I do use a USB extension so that may be the culprit but the extension worked fine with my Atrix 4G. I don't know but it is rather annoying waiting that long for a charge.
Sent from my SAMSUNG-SGH-I747 using Tapatalk 2

The charger that comes with your phone is 1amp, and your computer's USB port is 0.5amp, which is why it's taking twice as long to charge. It should only take about 15 minutes to charge each 10% under 90%, and 30minutes for the final 10% (about 3 hours total)
Also, when on 0.5amp, if the phone's display brightness is set to 100%, it will barely charge at all, and even discharge under some conditions (gaming, etc)
Charging times on 0.5amp, 1.0amp, and 2.1amp chargers

Yeah, it takes way longer for me... Not sure what the problem is then. It did it even when I was running stock software. Thanks for your time, I appreciate your help.

If your USB extension is just a charging cable, and not a data cable, then the phone will not think it is plugged into an AC charging outlet, and only allow the 500mA data port limit. The USB port has 4 wires, the middle two are shorted together to show that it is an AC charger, allowing the full 1 amp(or 750mA as some say), but if your extention is only a charging extension it wont see the middle wires shorted, think its plugged into a computer USB port, and charge at a Max of 500mA

Fast charge question

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.

[Q] Charging Problems...

Hello there,
I had bought the Samsung Galaxy S3 pretty much a week after it had been stocked in the shops. I got it with T-Mobile on contract and recently it takes like 4 hours to charge the phone through the PC, I'm currently sending the wall charger back with the 2 year warranty that European Trading Standards give as it doesn't work at all with any device.
Little Bit Information:
Rooted: Yes
ROM: CyanogenMod 10 (Latest Nightly)
USB Charger: The one that came with the phone
Please could anyone suggest or tell me how to fix this horrendous issue,
Much appreciated,
Thanks,
Josh

Plug it into the wall instead of your computer. Most newer devices (like the iPad, for instance) take forever to charge through the PC, but charge very fast from outlet. 4 hours through the PC sounds about right.

-.-

AKA: I have no plug charger...

Hope I'm wrong but i don't think there is a solution for you then, it requires a certain amount of voltage or amps to charge at a normal (wall charger) rate. Maybe try a ps3 or Xbox it might put more power out?

go to store buy adapter...this is not an issue with the phone it is an issue with you not having the proper accessories

You could use ktoonsez kernel. It has a fast charge option for usb charging. There is a warning it may cause damage to usb in rare cases but I do it all the time never any issues. May be a temp. Fix til you get your new wall charger.

If you're stuck with a PC USB port, best thing is to just do a slimming down. In my experience streaming music or video is the biggest killer, at least on wifi.

You have to remember that when you charge from a computer your phone connect to it and begains to communicate with it. Even without doing any file transfers it still connected and using more juice. From my understanding the fast usb charging on the kernel mentioned turns of the transfer ability to increase charging time. If you dont want to wait for your replacement then go buy one from walmart.

Get a kernel which supports fast charging. Faux and ktoonsez I know for sure has it. Charging is like half of what you said and 2 hours when screen is off

[Q] Very slow charging. why??

When i connect my galaxy note 2 to stock charger it shows that in my battery stats it's charging as USB not AC.
Well what's supposed to be the problem. is my charger broken or the usb port in my phone is damaged??

Are you using the stock charger with the stock USB cable? My note 2 was charging really slow until I realized that the USB extension cable I was using wasn't delivering enough juice.

Do you have another 2A charger/USB cable that you can test from? I use an HP Touchpad charger + cable because its 2A and has a long cable.

I just happen to experience the same thing. I have had my Note II for a couple of weeks now and it have always charged from almost empty to full in less than 2,5 hours. Today however, it's going really slow. I do not know why. I've tried everything I can think of. I juse only the stock charger. Also tried the Ipad charger - no luck. This seem to be a quite common problem.

Hmm, just as I thought, more and more of this should be coming in upcoming days. I lost two good night's sleep because of this. Anyway, this is what I have done and you guys SHOULD do.

first time ever i have faced this issue (slow charging) couple of days back. it was dropped to almost 1%/3min
I have simply reboot to recovery and wiped cache
Now it come back to normal 40%/hr.

I have discovered that the stock charging usb-cable only has 4 pins in the micro-usb end. It looks like on is missing, from the standard five-pins. Can anyone check your stock usbs and see if there are four or five pins, and report back? Thanks!

I've mentioned it on my topic, I'm sure you haven't read it. Look above.
Anyway, mine has 4 pins.

My cable got only 4 pins. The second from the right is missing if you have the USB logo up.

I found a huge variance in charging rates based on a combination of chargers and cables. Goes to show that the cable makes a huge difference. Here's my findings:
** Stock Charger (2A):
w/Stock Cable (4-pin) - 1698
w/Cable from another phone (5-pin) - 1698
w/Cable from battery pack (5-pin)- 1698
w/generic eBay cable (4-pin)- 100! - It didn't charge at all, even with screen off.
** iPhone Charger (1A):
w/Stock Cable (4-pin) - 1300
w/Cable from another phone (5-pin) - 1100
w/Cable from battery pack (5-pin) - 1300
w/generic eBay cable (4-pin) - 100!
** Car Charger (1A):
w/another generic eBay cable - 490
