This DIY is based upon work done by ericlmccormick.

*DIY means DIAYOR (Do It At Your Own Risk). I'm not responsible if you break/bend/mutilate/damage/fold/crater/molest/etc. your tablet as a result of following these instructions.

**If you're running Pershoot's kernel, you don't need to do this. You can enable Anycharge through the kernel. See here.

***Thanks to MRBR7 for testing and confirming this also works for the GTab 7.7 6800gt.

****Thanks to m_1000rr6 for testing and confirming this also works for the GTab 8.9 LTE.

****Thanks to NRGZ28 for testing and confirming this also works for the Original Verizon GTab 7.

TOOLS
(Left to Right)
- Something to hold the tiny pieces together while you solder
- Wire snips
- Solder
- Pliers
- Soldering Iron
attachment.php


PARTS
(Left to Right)
- Male USB Connector
- Female USB Connector
- One 33K Resistor
- One 10k Resistor
attachment.php

I ripped my USB connectors out of a USB extension cable.
attachment.php

Cleaned them up a bit.
attachment.php


IMPORTANT
Pay constant attention to the orientation of the USB connectors to each other and which pins are GND and +5V. You could damage your Tab if you end up switching GND and +5V by mistake. You could also end up with a non-working adapter if you flip the resister locations.

STEP 1
Place the resisters side by side and solder their leads together on one side. Then solder them to the D pins of the female USB connector. Make sure the 10K resistor is on the D pin closest to GND! Keep the trimmed resistor leads for use in Step 4.
attachment.php


STEP 2
Angle the non-soldered ends of the two resistors away from each other so they line up with the GND and +5V pins of the male USB connector. Make sure the USB connectors are aligned so their respective GND and +5V pins are on the same sides! Solder.
attachment.php


STEP 3
Now clip the resistor leads that were bent back towards the female USB connector and solder them to its GND and +5V pins. Double check that the USB connectors are aligned so their respective GND and +5V pins are on the same sides! BE PARANOID.
attachment.php


STEP 4
Use the trimmed resistor lead you kept from Step 1 to solder the chassis of the USB connectors together.
attachment.php


STEP 5
Take 5 minutes to admire your handiwork.
attachment.php


STEP 6 (IMPORTANT - DO NOT SKIP)
Take 10 minutes to check the following
(1) USB connectors are lined up correctly. GND & +5V are not crossed.
(2) 10K resistor comes from GND and 33K resistor comes from +5V. Adapter won't work otherwise.
(3) There are not short circuits / crossed / touching wires. Many bad things could happen.

STEP 7 (TEST)
Without adapter. @$%#!
attachment.php

With adapter. Success!
attachment.php

NEVER CONNECT YOUR TAB TO A USB PORT THAT SUPPLIES MORE THAN 2A - BE PARANOID.

STEP 8
Reinforcing and packaging (paperclips & electrical tape).

Thank me (hit that button over there ;)

Hope you found this post useful and informative.

Thanks for the guide, I'll have to try and make my own tomorrow. It'll be nice to charge it with anything now.

Nice! No chance I'll ever try to do this, but the fact you spent so much time putting the guide together deserves a thanks!

Theres a hack for galaxy tab 10.1 running pershoot's 1.4 oc kernel where you can make it so that your tab charges with ANYTHING instead of showing an x over the battery :)

You are correct, I even used to use Pershoot's kernel with this fix - that's why I didn't make the adapter until recently. This is for all the people running a kernel that doesn't support anycharge. I'll update the OP to include info about Pershoot's kernel anycharge.

Awesome work dude, I bought a couple of adapters a while back, because something like this didn't exist, real thorough guide, nice work. :D

Can anybody please confirm this method would work with a 7.7 6800gt?
Thanks....

Going to add an update method i discovered.
Just need to connect red power and earth no data lines or resisters are necesary.
Put a on/off switch on the earth to cut it.
First apply power with earth connected..
When get the red x...
Simply dis connect the earth and re apply via your switch.
When its re applyd this forces AC Charge mode from having red x before...
Have tested this using both 2amps and 1/2amp @ 5 volts.
Method works on both...
Try it and let me know,it works on my 7.7 tab...

If you cover the D+ D- with a piece of paper it'll do the trick ;)

For the record, having the charger provide more than 2A isn't actually dangerous. The tablet should only draw what it needs.

Then again, the fact that Samsung did something this goofy means they could easily have it overdraw by assuming any charger that has this is 2.1A or less, so the advice is probably good either way. But iPad chargers which deliver 2.1A should be safe.

Recently bought a used 10.1 that came without a charger.

Just successfully did this to use any usb charger.

Thanks OP! :)
