[Galaxy Tab General] Fixup:
Once you add these two resistors, some phones such as Moto Droid X can no longer be charged with the same adapter.
[Galaxy Tab General] rob_nz:
I just used a spare double-headed cable from a portable hdd that fortunately has a full size usb plug on the other end. (Most have mini-usb at the drive end)

I use it with a female-female usb adapter and it works pretty well for the PC, particularly on USB 3.0 ports.

I also saw these on Amazon:

amazon dot com/Apricorn-Power-Adapter-Cable-AUSB-Y/dp/B000JIOHDE

I believe Blackberry do one for the Storm as a standard accessory as well

For the car I got a car charger designed for iPad with a USB socket that delivers up to 2.1A

Belkin has the car charger

belkin dot com/IWCatProductPage.process?Product_Id=525940

(I should say, I don't actually have this one, mine is a generic brand that also has a 1A usb socket)

My wife is a phd microbiologist. Her phd advisor used to say "g-d can have an opinion... all others must bring data." So here is what I measured with a DVM using the tab and it's power supply as well as an ipad 2A charger and a kindle 1A charger.

If you measure the Samsung charger with power on you will find 1.25V on both data lines which are in fact tied together. This is almost exactly what you get if you use the resistors as posited earlier. The ipad charger measures 0 V at the same point as it does short and float the data lines. If you tie the data lines together and just let them float, the tab 10.1 does not go into fast charge mode. If you use the resistors(or presumably any other method) to put 1.25V or so on the shorted data lines, it does go into fast charge mode. This worked with a 2A ipad charger and a 1A kindle charger as well as a generic 500ma usb 'dumb' phone charger.

As usual, Samsung did not adhere to the standard. If that surprises you, go to wikipedia and read about the standardized PDMI dock connector that they also did not use.
[Galaxy Tab General] Mamukat:
Got mine working

I just made an adapter and it works like a charm.

Attaching a photo of the finished adapter, I didn't take photos during the build unfortunately.

I had to buy the resistors so the total money spent was about 0,20 € + some time. The connectors are from an old usb extension cable I didn't need and some bits of wire I used came from a cat6 network cable. I filled it with hot glue to keep it in place and then wrapped it with vulcanizing tape. I'll change the tape to Sugru after I get some more tomorrow, mine was beyond expiration date and gone solid.

This is about as short as you can make it, won't stick out much from usb port. It works perfectly. I haven't tested the charging times yet, but I expect similar results as other people have reported on this thread. Connecting to a computer using this adapter shows normal charging icon on the tab.

So I can confirm that this thing works, in case someone else is thinking about this solution.
[Galaxy Tab General] flast:
Sorry but I don't understand this thread.

Deal extreme sells an adapter for $3.50 including postage, I use 3 of them with any USB charger.

Admittedly it's a cool project.
[Galaxy Tab General] Mamukat:
Exactly why. :)

I made 2 just because the first one was so fun to build, and I had extra materials.

I actually tried to find one from online stores, but in all cases I found the total cost would have been close to 20€ with postage (I live in Finland). I found these things mostly from US stores, and therefore the postage was quite high.

I almost bought one from German Amazon for 2,50€ + about 8€ for postage, but I thought there's no point spending 10€ (about $13) for something I can make myself for 20 cents.

[Galaxy Tab General] synonymous11:
After following some of the above and prior advice on modifying the USB to make my Galaxy Tab Plus 7.0 charge properly, I decided to start with a USB car charger. The one in particular is specified as a 3amp device total over 2 USB ports, so if it is anything close to spec in reality, it aught to provide enough power to charge my tablet. Next, other than the resistors, failing to find any cheap parts or cables to modify at the local radio shack, I decided to try it one step better. I decided to try opening up the car charger itself and just soldering the resistors at the source. After opening, I found adequate space to do the work and simply I chose the easiest accessible port to do my soldering work. If you have any questions on pinouts and identifying which resistor goes where, you can reference the earlier posts and other sites for clarification. I also used the 33K resistor on the +5(red) and the 10K resistor on the ground(black) pins, with them center tapped on both connected data lines. The charger in particular was from Best Buy and is named RocketFish. Seems to be working so far!!
[Galaxy Tab General] aludden:
I had the same problem with my tablet, a LePan II, and someone directed me to this thread. These posts helped me make my adapter cable - thanks!

In my case, no resistors are needed, but I found out that the car adapter I am using (i-xt at Walmart for $12) does put out 1.95 V on one data line and 2.56V on the other. So it may work for your Galaxy Tab with no modifications. You may want to check it out.
[Galaxy Tab General] va4ik:
Hi I managed to solder the usb extension cable with the resistors as described.

It works like charm with apple usb charger.

Please take a look on the attached pictures.
[Galaxy Tab General] gildow:
Quick Question, not sure if this has been asked before, but as long as we are on the issue of charging cable, I realized that I could charge my tab using my mac...that was not possible before I've installed ICS...am I the only one? Or all these charging "issue" can be fixed by software?
[Galaxy Tab General] va4ik:
It can not take more than 0.5A from a mac. In such case original ROM will display red cross over the battery icon. In both cases the charging is not optimal because it requires 2A for good charging.
[Galaxy Tab General] gildow:
Thanks for clearing that up.
[Galaxy Tab General] hemligsomfan:
There is acualy one USB-port on some Macbooks that is wired to become an Superduperextrastrong chargingport when an iPad is connected. Ofcourse there is an correct name for it, but you get the point.

There is also an softwarefix for this issue, but that is sorted by rooting and installing a custom kernel that gives the user the option to force the Charge with full power feature the above mentioned adaptor does the "hard" way.

B.t.w. in progres off uppgrading an original cable by soldering the resistors direktly into the 30-pin connector. Its quite roomie in there. Pics will be posted.

sorry to hijack the thread but if you bridge the data lines (d+ & d-), will/should the device still tell you that it's charging from a usb port and not an a/c charger..?

This work with galaxy note 10.1?
[Galaxy Tab General] Dabidue:
I also use Humberos ROM and JB 4.2.2 from Alroger on my P1000 (gsm version).

But when using fast usb charging with other than stock charger you should use some market tools which are able to obey the temperature! :eek:
[Galaxy Tab General] ytj87:
I'd bet the Note 2, and all Samsung devices, use the same setup as the original Galaxy S. That is, if the two data pins are shorted together, the phone kicks into fast charge mode and draws more current. Many old discussions on this.

There are two simple solutions:

1. Solder the internal data pins inside a charger. Use with any cable thereafter.

2. Use a tiny piece of aluminum foil to short the data pins inside a USB cable's male tip. Use with any charger thereafter.
[Galaxy Tab General] R-P:
I think the whole discussion is that it does NOT work like this. I ended up in this thread because the Tab2 7" doesn't 'charge' from my 1A HTC charger, and with "doesn't charge" I mean that it shows a red cross or something in the battery icon.

I thought I had figured it all out after testing an iPad3 thoroughly and finding all its chargingfunctions (0.9, 1.36, 1.9 and 2.2A depending on resistorvalues of datapins)... Now I find Samsung also has a couple of tricks up its sleeve...:confused:

My wife's Galaxy S charger is 850mA and my HTC never charged with more than 850mA (according to Spooncharge, any Android version of this?) if memory serves me right even though the charger was a 1A version. So I would not be surprised if the tablet actually charges at a greater current than just 500mA. But 850mA is probably still not enough to run the screen and some apps...

5v 2amps galaxy note2

Hi, I tried 33k and 10k resistors to charge my galaxy note 2, but it only takes 1Amp from 5V source (and charging is slower), original charger charges with 2Amp, so I wonder if somebody has another wire diagram for Samsung galaxy note 2 with current 2Amps ?

Can charge my Galaxy p6200 AND use data pins?

I have an usb sdr adapter (software radio).

I want to connect it to my Galaxy Tab P6200, to listen to radios.

The P6200 doesn't have enough current in it's usb's to power up the usb's sdr, so, I am powering it (the usb sdr) using an external power suply.

Even so, the Galaxy's batter is being drained fast.

Is there any way to connect the usb's sdr AND, while using the apk to listen to radios, charge the battery?

Thanks for any help.

[Galaxy Tab General] steve.rand:
I performed this mod to a 3amp charger the other day. The voltages my stock charger put out match what was quoted here... 5, and two 1.5.

Using factory cable on my Note 2 with my generic 3amp charger, 460mah rate. After mod, 1800mah rate.

33k to positive, 10k to negative, both resistor ends to both data wires. Resistor tolerance bands facing phone, there's not much else to it!

Make sure the charger you are trying it with is rated for 2amps. It might regulate to 1amp or it might burn out if it can only do around 1amp safely.
[Galaxy Tab General] fastguy:
I tried this on note 10.1 2014 Snapdragon version, did not differ from chargin with shorted D+ D- pins. It could only hit 1500-1600 mah. Maybe this one asks for 82k resistors as I saw in some S4 charging thread?
[Galaxy Tab General] Galane:
I'm going to try this on my Galaxy Tab 3 7". It will charge from my Galaxy S4 phone charger, which will also bring it up from a totally dead battery. But the tab will barely trickle charge from anything else, even a 2.1 amp Belkin iPad charger, and it won't come alive from a dead battery with anything but the S4 charger.

The phone will pull 460ma from a normal USB port and 1,900ma from the charger that came with it and the same from the Belkin charger. I assume the S4's charger has the 1.25V on the data lines. The Belkin charger must not or has iDevice compatible voltage on the data lines or they are simply shorted together. However it is, the Belkin does not output what the GT3 7" expects.

Now I have to cut the internal connector off the crappy aftermarket battery I bought for the GT3 to replace the original because one end of it broke off and apparently the contact that sends power to the circuit which monitors the power button is not making contact. The charge icon lights up and the original battery has been taking quite a while longer to charge off the S4 charger than the cheap replacement battery. Hopefully that's an indication it's actually 4,000mah and the cheap battery is considerably less. If I left it unplugged and off overnight the battery would be almost dead by morning. (Of course the GT3 7" is known for lousy power management, hopefully to be fixed *if* the GT3 7" ever gets Lollipop in the USA! Also waiting on Lolli for the S4. The rest of the planet has it on these, why don't we?!)

Had I known about Samsung's silly non-standard charging setup before I bought a supposedly genuine Samsung (black) charger off eBay (it went missing somewhere) and another white one - which I very carefully compared the printing in the images on eBay to my known genuine charger before ordering it... Only to find when I got it that it would barely charge my S4 and the tablet not at all, then it died. Closer examination showed the color of the text on the ersatz white charger was a slightly different color and the text size in the SAMSUNG logo was a slightly different size and the fake-o weighed a gram or so less. Would be nice if Samsung and eBay would crack down on all the sellers of counterfeit chargers!

Currently I'm using MDJFroyo Sense Revolution with the latest kernel or at least the one release a few days ago. I was a DarkStone fan for the longest (the longest length of time with his build was 2 months) and wanted to try a stock build, but didn't like it cause of data isssues. So I bounced from buil to build until I saw m-deejay releasing builds every week or at least updates and thought I'd give it a try.

So far, I really like it. Love that he includes a cool theme with his builds. Aside from looks the build is very stable. With the most recent kernel, data disconnects happen less frequently, and mostly when I'm at work and can't get much of a signal anyway. Thankfully my job is upstairs from a nursing school that offers its students free wi-fi lol.

Other than that, he keeps his builds updated which is also cool. I want to try another HD build, so when I get home I'll change a few things and go from there.

As far as set up:
