powermat mod - Galaxy Tab 10.1 Accessories

Hey everyone, just thought I would share that I managed to mod my phone to work with a powermat charger. I used the powermat back from a blackberry bold, which is currently on sale for $1.99 right now and soldered it to the micro-b end of an old cable. If there is interest, I'll take it apart and document it, but it's pretty straight-forward. Obviously the nub sticks out, but it's not any worse than some of the stock adapters, and a case would help.
I took a few photos, but this is my first post so xda won't let me share them with you.

[Q] Desk / Dash genie

Hey all,
This is my first post here.
Has any of you bought either of those products? They look really stylish and useful (specially the desk dock, which doubles as a USB hub and a 8 in 1 card reader).
Obviously, I can't post links yet, but you can look them up at MobileFun.co.uk and Amazon.co.uk. They are not really expensive either (around 15 pounds + shipping).
So, what are your thoughts on those products?
Many reviews i read (for the Dash Genie) said it worked well until the car got hot - then the phone slid on the tacky surface, and there was residue left on the phone. Sometimes a ring left on the dash.
Welcome to xda! Item looks useful. I wish samsung would expand their accessory line for their phones. I'd love a great windshield mount or dash mount/charger.

I have the Desk Genie and it does NOT stick to the back of the phone, whatsoever. Search for my post in the thread already created for this accessory and my review.

I'm actually pretty interested in the Desk Genie after reading about it but now you got me rethinking it. I assume you tried without a case on? I have the Amzer TPU case, which is fairly rubbery and grippy, so I wonder if that would allow the phone to stick to the surface better?
Any chance you can experiment with that if you have a TPU case lying around? Or maybe your general observations of if a TPU case would make a difference?
Also, since I assume the Desk Genie connects to the computer to charge, I assume that charging would take a bit longer due to the fact that you aren't using AC power? I assume you can still connect it to the AC adapter as that uses USB too, but then the USB ports on the side of the dock would be useless.

Thanks for the info. Do you use any type of case?
Only the "case" I made in my signature! I've tried everything to get it to stick to the aluminum battery cover, and it just won't do it, maybe it would work with certain cases, but if you're a anti-case person like me, then this won't work for you....
Great accesory!
So, I bought the Desk Genie, have been using it for about a week and I love it!
Contrary to the previous poster, I've had no problem whatsoever with it holding my phone, both in portrait and landscape mode. It even holds it with the otterbox commuter case on!
The product is very stylish and useful. Both USB ports work great and the card reader accepts Micro SD cards without adapters (I haven't run any speed tests).
It comes a mini USB-USB cable with which you connect the DG to the computer via a port in the back, and a power cable with which you charge the phone using one of the 8 provided plugs.
The phone recognizes it as charging via AC power! I found that very interesting, given that the DG is powered by the computer USB port.
All in all, I fully recommend this item. Wish I'd bought it sooner.

This means the data pins are shorted, just like in a samsung charger. Can you connect to mass storage with this dock?

USB data cable

Do any of you guys and gals know of an aftermarket cable that will work with the captivate. I lost the original one that came with the phone. Have since bought two different chargers, one from the att store (zero charger), and they charge the phone but don't put it on USB mode like the original one did when I plug it to a laptop.

All you need is a standard MicroUSB to USB cable. Make sure it's a standard cable, and not a "charge only" cable though.
A bit of advise, generally if you buy a cable that isn't a Samsung USB cable, you're going to have to take a razor blade to your new cable and cut away some of the rubber around the MicroUSB plug. You'll see that untrimmed, you might have a hard time getting the cable secured in the phone's port.
Thanks man. I actually just noticed the "charging only cable" written on the tag on the cable. Now I know what to look for. And you're right, the one I bought from a gas station was always popping out. The one from att fits like a glove though.
Sent from my rooted Cappy.
All it takes is a razor blade or something similar, and a few seconds. I use a bunch of generic USB cables which all have fat plug heads. Trimming a little of the rubber off and they all work perfect.
Weird, for some reason my original cable from ATT now is really loose, I have to like set the phone down a certain way to keep it charging/plugged in.
The only cables that now do fit snuggly are the ones from my external mini hard drives with the fat head, haha, I wonder why...my captivate still looks normal, can't figure it out.
I guess I should see if my normal cable fits with my externals or falls out of those too, if so it would be the cable. But it seems weird that the fat headed cables fit snuggly with my captivate, so that makes me think maybe its the captivate.
long winded stupid post, sorry.
i bought a blackberry cable from best buy... data and charging... 16 bucks. but when ever your puppy ate your data cable in the middle of the night and you're phone is at 30% battery, ya tend to pay for it...

Check out www all4cellular DOT com
They have the OEM Samsung Captivate (U.S./Edison) Wall Charger and USB Charging+Data Cable for $6.95 + $2 Shipping.
The item number is "eta0u60jbe". But this item # includes BOTH the USB Wall Charger (# ETA0U60JBE) AND the USB-to-Micro USB data/charging Cable (# ECC1DU2BBE)!
I bought two of these and they are EXACTLY like the original Charger and ~5ft. USB Cable that comes with the Captivate. They are OEM/Samsung-branded and labeled and are not Chinese-made knock-offs. I am in SoCal and received them within a few days of ordering.
Here's a direct link:

I had similar issues, till I realized that the problem was with the sliding door for the microUSB port - make sure it is pushed all the way back (you may hear a click) - its only then that all my MicroUSB cables fit w/out any modifications to them.
as always YMMV.
hope that helps
I second the Monoprice.com recommendation. I buy ALL my cables there. The heads on their micro USB cables are too large to plug into the Captivate unmodified, but I used a Dremel to fix that.
Both of my Monoprice cables are going strong, in contrast with my OEM cable, which started out excellent, but is now so loose as to not maintain a connection unless the phone and cable are precisely arranged.

I have the same problem with the original cable not fitting snug. Yes, the door is open all the way...until the click. I'm just glad to know I'm not the only one have the problem. Been doing it since day 1. I'm afraid to cut any bit of it off since its already slimmed down and there isn't much left to cut

I have a 1009 model. Assuming that means it was manufactured Sept,2010. Now to find a microUSB
We have some micro USB 5' Cables coming in Monday. If they are like the sample they not only fit the Captivate properly, but when plugged into our new Car Plug ->USB (2100mA) adapter, my Captivate shows "Charging (AC) ".
We originally brought in the Hi-Power USB car adapter so iPad & Tablet customers could both run & charge at the same time. We have had enough request from customers looking to use it with Smart Phones, that I had to find the best matching cable.

As mentioned, get your cables from monoprice. I mean, you just can't beat a usb cable for $2. If it needs trimmed, I usually just use a razor knife/box cutter to remove the bulk, and it works perfectly. I actually had to order a 25ft. VGA cable from them a couple of days ago...$8. Seriously. Definitely the cheapest place I've seen to buy cables.

[Q] Problems with the Samsung OEM data/charge cable

Any micro USB cables that you guys would recommend over the OEM original cable.
I seem to be one of the very few that have problems with the original cable fitting snuggly. Yes, the door is open all the way til it clicks, yet the cable easily falls out.
If anyone has a suggestion of another cable or has the same problem with a fix that I just somehow missed after searching for a couple of days, it would be greatly appreciated.
I had the same problem. After about a month of use it just came completely loose and would only stay in if I propped it up a certain way. I tried a friend's charger and it worked fine (likewise my charger was loose on his captivate).
I just took the usb cable from my external hard drive and that one fits very snuggly, unfortunately it is also much shorter
I'm also having this issue. I wonder why...

Yes, this is exactly what I have to do for mine to charge. So I guess I'll have to just start looking for one that will work for me. It seems just any other standard micro USB cable will do the trick. Thanks a lot my friend.

Well upon further inspection, you can see how the top of the phone is curved and if you look at with the USB door open from the top and tilted slightly back you can see how the jack actually looks crooked inside the phone. I'm quite sure that this is because of the curved top parallel to the circuit board that has the jack is too tall. And I think for some reason I might need to trim down the micro end a bit on the front side..it looks like its hitting the front side of the phone.
I'm looking for a replacement cable as well...even OEM is fine. The case around mine cracked off one night when I feel asleep playing on my phone. Mine was always kind of loose compared to the att charging cable which is nice and tight. Does radio shack carry cables like this?

i called AT&T about this with my cappy and they said that the charging port was bad and sent me a new phone , thats been 3 mo ago and the problem hasnt recurred.
(just a thought)
Search Amazon for "blackberry usb cable micro usb". The first result should be it, it's a very high quality, shielded cable. To get a solid, snug fit I suggest a razor or a knife to easily cut back some of the rubber around the micro tip. Works amazingly well. I could even make it work before I trimmed it.
just to elaborate, the specific micro end is called a "micro b " usb connection.
not to be confused with mini or micro a
of course the other end is just standard.
The place I work has a 5' nice quality cable that fits my Captivate tight. They got them to go with the 2100mA USB Car Charger we sell. Cost on the cable is $ 4.99 plus shipping (about $2.99 first class parcel).

I'm not sure if its quality, or just chance, but I've found that only some 3rd-party cables will work. I've tried a blackberry one that didn't work, and a really cheap one that did.
I would suggest keeping the one you got from samsung, just in case.
I'd like to know if anyone else had issues with cables not working?
I got a Samsung cable designed for the galaxy S on Amazon for like $6 with free shipping.

I had the same problem.
I used some tools(hammer,knife, etc) to fix the cable.
Now my cable works fine!!

I just used a razor blade to trim the rubber back, works great.
If you look at your cable. The black part and the silver part(part that goes in your phone) is not in a straight line.
Just try to make it straight. And use a knife to cut the rubber of the edge a little bit.
That should do the trick.

I haven't read all of the posts so I don't know if someone has already posted a solution to this problem, so I'll just answer.
I had this same problem. If you notice their are two tiny metal teeth that lock the charger into the phone. These teeth no longer stick out as far as they used to. That is why you are having this problem. The teeth are not bent. It is the micro usb plug that is around it. All that you need to do is give it a firm bush on the table. Bend the plug away from the teeth so that they stick out more. This fixed my problem.
When you put it back into your phone, you will notice that the plug is no longer in the phone at an angle.

You should saved me from buying 3 more cables. I distroyed my OEM cable to make a jig because I bricked my phone. I ordered 3 sets of cables and they all had the same problem.... Usb kept popping off. So I was just about to go out and order 3 more sets if cables, this time OEM untill I decided to read this tread. It never occured to me that it was fitting in well because of the extra rubber on the connector. I trimmed it down and now the cable snapped in perfectly like it was supposed to. Thanks for the fix!

I know this is getting old, but it took me about 2 hours to find an answer that WASN'T recommending to just make sure the slider was all the way open. For no reason at all, my phone cable just wouldn't hold a real connection this morning... your answer saved the day
For cables that are good quality and cheap, go to www.meritline.com ....... I have never gotten a bad cable from them, typically I use their HDMI cables but the USB cables are less complex and work just as well. My last usb cable was one of theirs.

[Q] Adding Inductive Charging?

In your opinion, how hard would it be to modify a case/back panel for the Glide, so that it has inductive charging support? I just saw a video online of someone internalizing an iPhone 4/4S charger, with only slight structural modifications (it had the appearance of no case on the outside), and was thinking that I might be able to do it to my Glide. At the moment, I am using a Body Glove case, made of rubber-coated plastic (the only one AT&T sells/sold for the Glide), and my best guess is that the case is about 3mm in thickness. I am looking for no actual phone modifications here (except for wiring the case to the battery, and maybe a modified back cover), so does anyone have any thoughts/ideas/suggestions?
Interesting. There is a company selling those inductive charging mats. I believe there is a connector that plugs to our phone (micro USB) to work with it. You could buy that and try to modify the phone back panel and a case to add the necessary hardware.

I saw this, and figured that's what I was going to use. However, It looks as if the case for most phones adds quite a bit of thickness. I looked at another guide, which involved ripping up a Palm Pre back, soldering some things together, and using the Touchstone mat. As for whether or not that would work with a Powermat, I am not sure.

I've seen that guide, it was for the galaxy s3.
It looks like that phone has the two charging pins below the back cover; looking at the glide, I can't see them.
I fear we would need circuitry or at least more complicated wiring to make it work.
The one I saw was for the original Galaxy S. You may have seen a different one. The video I saw showed him wiring some things directly to the battery, if I remember correctly.
any progress
Hey there!
I found this thread as THE only one where someone imagining about the glide having the possibility to charge inductively.
any new info about it?
@a_p3rson: did you find a way to do it?
I would love to see it becoming true..
best regards

So far, the best chance I've seen was using the induction sticker on the back for the Palm (pre I believe), and wiring it to the USB port. I think that would work pretty well, though I am worried with how it would affect the normal function of the USB port. If anyone wants to try it (and share the results), by all means, please do so!
EDIT: It wouldn't be possible to wire the sticker directly to the battery, right? Of course, without causing overcharging/overheating/general harm/etc. to the battery or any part of it?
just throw it out there i have a extended battery from amazon it is about twice as thick as stock batter new back cover has large empty space between camera and batter pack i mean could put flash drive with room to spare in there would be easy to add some new hardware in there if need be for you power matt bought mine of amaxon for 11.00

I seem to remember the sticker on the Pre being really thin - like paper thin. Plus, I really am against cosmetic things like that (e.g. large back, extended battery), so an extended back shouldn't be needed.
However, I do know that the guide that I found (for the Galaxy S) said that it was possible by just wiring the sticker to the charging ports in the USB connector. The only worry I have is if the phone's USB communication would be affected at all.
If it is possible to just directly wire into the charging ports, there appears to be an easily removable panel directly above the microusb port that would presumably give access to it. I'm at work right now, so I can't exactly check, just puttin it out there.

Did you ever see if it was possible to hook the induction sticker to the USB port from here? I just looked at the panel, and it actually looks like there is a sticker that contains some wires going to the main board on that plate, makes me think that it could be an antenna of some sort, and that it might be kind of hard to deal with.

Wireless charging experiment

OK, after getting my One for Xmas and a little extra coin to spend, I am going to attempt to add on wireless charging.
Due to the nature of my work, I need a case to be on the phone. I destroyed two Thunderbolts before I finally corrected my rectal-cranial inversion and put it in a case. So I ordered up a UAG case for my One. After some research, I stumbled upon a little gem on ebay, a QI charging receiver with a microUSB connector. I figured for $8.50, why not? I will not be putting the pad inside of the battery door, but between the phone and the case. I also ordered up a no-name QI charging pad.
I will update the thread when everything comes in and let you know how well (or poorly) the whole scheme works. I know I am losing my ability to plug into the USB port, but I can use a Samba app to transfer files if need be. Also of note, I don't use NFC, so I will never know whether it affects NFC's ability to read.
If anybody has any questions or feedback, please let me know. What I'm hoping to do with this little project is add some functionality to an already amazing device without causing any cosmetic harm or irreversible alterations to a sexy design I will hate to hide in a case.
