This guide is based on [GUIDE] The $6 way to charging your EEE Pad on your computer, taken one step further.
DISCLAIMER! YOU DO THIS ON YOUR OWN RISK! IF YOU SCREW SOMETHING UP ITS NOT MY FAULT!
This guide will show you how you can charge your TF101 from the PC, while also have it connected through USB allowing you to sync etc just as you normally would.
Its possible this method also works on the TF201, but I dont know for sure.
Difficulty: Pisseasy
Parts and tools needed:
A female molex connector with the yellow(+12v) and black(ground) wire. Where you get it from doesnt matter. I stole mine from an old pci-e -> molex adapter.
Headphone extension cord (or any other 2-wire cable you can use as a connector)
USB extension cord (2.0 works fine, no need to get a 3.0)
Tape (or if youre not as lazy as me - a soldering iron)
Teeth (or a wire-stripper/cutter)
Carpet knife or similar
Multimeter, not necessary but recommended to check if the power is correct before hooking it up to your tablet.
Ok, lets get started!
Id like to apologize for the rather vague images. I took them after I had actually built the cable.
Grab the male end of the headphone extension cord and cut it, leaving a bit of cable (I left around 20cm)
Next, grab the USB Extension cord.
I wish I had a better picture for this, but its not that tricky. What you want to do is remove the cover around the shielding, remove the shielding and exposing the 4 wires.
Once thats done, cut the red and black wires, leave the green and white.
Strip the red and black wires going towards the female end of the extension cord.
Connect the white and red wire from the male audio extension cord to the red and black wire on the usb extension cord. I suggest you attach red to red, white to black. It doesnt matter much though, but do remember how you connect them.
If done correctly you should end up with something similar as the picture.
Grab your favorite roll of tape and secure the wires and you should end up with this
Gratz, the first part is complete! Now to steal some power from the PC.
Grab the remaining part of the audio extension cord, which should contain the female connection.
Grab your molex connector (In the picture, I have already stolen one of the molex connectors)
Now, strip the yellow and black wire on the molex connector, and strip the red and white cable on the female audio cord.
Connect them the same way you did with the usb cable (if you followed my example, yellow goes to red, black goes to white).
Excuse my extremely dusty PC... Im ashamed :x
this might be a good part to route the molex-female audio cable inside the PC so it reaches outside.
Once thats done, simply hook the molex connector up to a free connector in your PC
And finally, grab your usb-male audio cable, connect the male audio with the female audio and plug the usb end into a free usb port.
Finally! Hook up your original TF101 usb cable to the female end of the USB cord and enjoy being able to charge your tablet while transfering files!
WARNING! Do NOT connect anything but the TF to this cable. 12v will fry any normal USB device.
Troubleshooting:
If your tablet does not react when you connect it, you have most likely gotten the polarities wrong. Simply switch the place of either red/black on the usb cable, or yellow/black on the molex connector (this is where a multimeter is handy).
There are many ways of doing this, I chose to do it like this because I had an audio extension cord lying around, and I wanted to be able to detach the cable from the PC.
Basically all you have to do is cut the red and black wire from the usb cable, and hook them up to the 12v rail on your PC instead of the 5v rail USB is running on.
How you chose to do this is, in the end, up to you.
Additionally, if you replace the audio jacks with some other more standard DC plug, you could use this cable to charge your TF using any DC adapter that provides 12-15V.
Once I get a USB Extension Kit for my TF, Im going to try to add a charging port to that as well. If I succeed in that, Ill post another guide covering that.
If you found this guide useful, hit 'thanks'
