USB data/charging cable

Does anyone know of a good (doesn't have to be OEM) data/charging cable that will work with the 10.1 tab? I saw a few non-OEM ones on Amazon but the reviews say they don't work (one person says it won't charge, another says it charges but won't do data). I guess I'm willing to pay for an OEM cable if someone can tell me which ones are compatible with the 10.1. Samsung live chat says they can't provide this info because the device is not officially released yet. Didn't seem like they were simply dumb or unwilling, just that support folks don't have the info/training/specs yet.

The 10.1v seems to need at least 2A output to charge and the only 2A output charger mains to USB adaptor I have is the one that came with it.
Some in Australia have tested the standard cable with third party 2A output chargers with no luck. Others say that their Samsung branded chargers from the original Galaxy Tab work fine.
I bought a 75cm retractable third party cable (labelled as working for the original Galaxy Tab) and it works for both data and charging on my 10.1v. I'm going to try my luck and buy a 3m third party cable as the 1m one provided by Samsung is simply too short to be practical for me.
Oh and the 10.1v, like the iPad (and original Galaxy Tab), will not charge over USB from most PCs.

They do charge from powered USB (1amp) just veeeery sloooowly
From a non-powered (500 milliamp) usb port, you're probably draining it quicker than it is charging
The original Galaxy Tab was also 2amp

Wall charger ...

Hi,
Can you use the wall charger from the Galaxy Tab 7" ?
Please if you have both devices to try it.
I would like to import this new 10.1" to Europe, The Netherlands.
And I am wondering the wall charger requirements.
Thanks.

I would also be interested to know if the charging cable is compatible between the original Galaxy Tab and the Galaxy Tab 10.1.

Yes it works. I'm using my cable that came with my 10.1 to keep plugged into my PC and I'm currently charging my 10.1 on the cable that came with my 7. It went from 0 to 50% so far no problems. Not sure if it charges any faster/slower than the one that came with it but I'd assume they are the same.

Thanks, so I can order NL gt 7 charger for my US gt 10.1 for use here in NL.
Sweeettt ...

Thanks for that. Picked up a couple of genuine Samsung chargers from Tesco in the UK for £4.97 each (reduced from something like £40!). Potential UK buyers might want to grab a spare while they can!

i think he was saying that the cable will work. The charger might not. I was trying to use my cable with other USB wall chargers but the device won't charge on them... my guess is because they are less than 2ah. I would make sure the specs on the tab 7 charger match up to the 10.1 charger to be safe

The Galaxy Tab charger I picked up today is rated at 2A so it should be OK, with any luck!

cable and charger both work. both chargers are 5v 2A. one reason why it charges slower than the xoom and tf.
on the upside it does trickle charge via standard usb. my tf won't and of course my ex xoom wouldn't.

Sweet, i'm gonna have to pick one of these up then

Wow, those chargers are expensive on amazon. Does anyone know where to get cheap ones?

Ebay is probably the best place for all things cheap, unless you're wanting a samsung branded charger

Haven't checked for the exact right one but dealextreme.com has been the best in the past for misc electronics cheap.

good to know that. like many android gadgets, once you have it, next natural thing is to put several chargers in several places.

Probably if anyone can post photo / link to the gt tab 7 charger?
So, we all know what to look for specific.

I hate how you can't just plug it into any usb. I have usb adapters everywhere and it would be nice if I could charge it while plugged into my computer

I posted this in another thread, but with these adapters, you can charge off ANY USB port;

I've bought two, leave one at home and the other comes travelling with me.
I also use a few third party cables designed for the original Galaxy Tab and they work fine. So happy to be able to charge my 10.1v anywhere

it does, but it seems like 1% per 3 min. just plug it in and see. it's the only honeycomb tablet that i've had that actually does charge via usb (xoom, tf, and gt101). the tf doesn't, but i'm sure it would if i had usb 3.0.

Thanks for this! I saw your other post and went ebay chasing, but the link made it much easier...

I really want a wall charger I can throw in my flight bag. Anyone have one they've found on eBay that charges the Tab 10.1? I really don't want to drop $40 for the OEM, ouch!

Seriously, why not buy one of the adapters that I posted about and use any charger you want? I think I paid about $7 Australian for two and now I can keep using all of the USB wall and car chargers I have amassed over the years owning Win Mobile and Android phones
If your heart is really set on buying a proper wall charger, if it says it will charge a Galaxy Tab (original) or iPad, it should charge the 10.1

Beware of USB cable and charger

I thought I had a bad ROM, but apparently it was a bad cable. And it seems as though the geniune cable does a "bit" more.
I didn't even think there would be a difference in between my Samsung Galaxy S3 cable and the Samsung Galaxy Note 8.0 cable, but there is.
I've been using an app call Galaxy Current Lite to see why it's been taking 8 hours to charge from 4%-100%. I have used the original charger cable that came with my Note 8.0 as well as the original set that came with my SGS3. Both yield the same result. Galaxy Current Lite showed max 500ma was going through.
After being frustrated I took my Note 8.0 to a store with another Note 8.0 store display, plugged it in and check it with Galaxy Current app... load and behold it was getting 1800ma.
So apparently the cable does make a difference. So I went to buy the geniune Samsung travel kit, while I deal with warranty replacement from Samsung tomorrow. I also found out that using a cable that is for Note 8.0 via my SGS3 or Apple AC to USB also gave a 1100ma and 900ma respectively.
So if you are having issues SLOW charging... grab the app and check. It could be the cable. And if it is... DO NOT GET A GENERIC. I tried a generic charging ONLY cable with the original Samsung charger it yield 468ma
Hope this will help others

Let me first confirm this and also post some of my findings in the past.
I have 3 samsung oem ones all having issues and then a generic and another from a nokia and they are the ones I've been using as they are shorter + thicker and give me 1800 ma constantly. I don't have any issues with generic ones as long as you use original charger.
When my note 8 went to service center for mother board and screen replacement (liquid damage), I confirmed with tech if there was something special inside the samsung cable, and was told that though he cannot disclose that, but even if there was, it's not related to charging, told me to just use any good/decent quality cable.
The Nokia one I have is CA-101D and it's extremely short in length (few inches) but good enough for unattended charging on table.
Apart from galaxy current like, one can also use battery monitor widget and in it's settings set measuring method to samsung one and it will also start showing what current you are getting as well as track charge/drain cycles.

I purposely use a 0.7A to charge my Note 8 overnight..

Genuine or not is not the point. One should use a cable designed to carry the needed current. Some cables are designed to carry only 500mA or 1A, especially in the old days. Nowadays with the power hungry smart phones/tablets, you would want to use a cable that can carry at least 2A or even 3A. If you are not looking specifically for these spec and grab just any USB cable randomly, chances are you would be limiting the current. Certainly the Samsung cable that comes with your device would supply sufficient current. But if you don't feel like traveling with a dedicated cable for each one of your devices, just buy a 3A rated cable, it would work across all of your devices. A 3A cable would be future proof for a while.

I tried some current apps, and found them to drain my battery, so be careful.
I used 2 meter Sony, BlackBerry, no name brands, and a case logic 10 footer. All did very well with high current charging.
The OEM Samsung almost killed my Note 8.0 by fire! After a few months the thin wires shorted out at the micro usb plug, and super heated. Won't use Samsung cables anymore.
My issue is plug life, micro usb sux big time for plug in design. No wonder USB3 has become a popular change to manufacturers of chargeable devices.

Replacing Micro-USB charger cable

I have a Galaxy S4 i9505 with the original charger, although I had to change the cable to my shorter Nexus 7 cable since the connector on the end of the cable must have been damaged, I couldn't use my phone or it would keep changing and unplugging. Anyway, I bought a longer cable ages ago, at least 3 metres but the charging rate was rubbish. So I'm just curious if anyway has bought aftermarket USB to Micro-USB which has kept the same charge rate as their stock cable?
Thanks.

The cable doesn't really matter, as long as it's not some cheap eBay no-brand cable. Stick with OEM from a major brand, or Amazon Basics.

Some questions on charging battery issue

Hey guys. Just wanna ask some question.
My note 10.1 2014 P601 is now running stock 5.1.1 un-rooted. Basically everything stock. I know that our Note need its own charger to work properly. But I lost the original charger long ago, and I've been using only the USB I bought separately to charge my tablet by connecting it to PC.
Now, my mother just bought a new phone (Galaxy A7) and when I try to charge my tablet with her charger, sometime it shows X mark (which means insufficient, exactly like when i connect to pc via USB cable) on the battery icon, but sometime it shows the lightning (which is fine) icon. The speed of the charge depends on that sign, if on lightning sign, from 0 to 100% takes about 4h. But if on the X mark sign, 4h will just get around 40%.
I don't really know what happened, but I have to unplug then re-plug again and again to get the lightning sign to come up. I then bought a new charger (from a legit well-known store and they said it's the best quality) and it does the same thing. I haven't got a chance to borrow anyone's original note charger yet as I found no one using this device. And now I start to think it's the problem with my Note more likely than anything. I haven't tried to reinstall the firmware either as I just updated the firmware like few months ago.
I've been using it for about a year btw. Sorry for my English. And looking forward to hear from you all.

The usb jack or its solder contacts may be damaged. Also, if no case is used and the backside of the Note squeezed when holding it in your hands, the cables for usb and display may work themselves slowly out of their pcb connectors. I don't know if the squeeze theory is right, but definitely there are many loose cables...
A charger must be Qualcomm Quickcharge or Apple iPad compatible, 5v 2A. I haven't used a Sammy Charger for a single time,tho they seem just too good to throw away.

Are you sure the Qualcomm Quickcharge would work on this P601? I checked the list before and I didn't see the Note 10.1. Not even the Note 3 which was released together. I afraid that being "not compatible" might fry the device.
If you're using one and not having any problem, can you post the link to the product that you're using and working well?

I forgot about the different SoCs. However, all models charge at 5v/2A and the signaling technique used for Quickcharge seems to be borrowed from that of the Apple iPad, the Exynos based models should be just the same. I plugged my Note into an Apple compatible charger, which was from a time when Android smartphones were charging at 0,9A and Android tablets had proprietory connectors, and it was charging at 2A.
