3. In the last series of photo's you've cut the powermat before fitting it to the in car vent holder, is there anything I should specifically watch out for before cutting the X1?

What I'm thinking of doing is fitting the receiver to an Otterbox case for a S2 and then mounting the X1 onto one of these.

Any help appreciated guys.
here are pictures of my setup using an Otterbox Commuter case. SOrry it took so long.

As far as cutting the X1, most of the electronics is positioned in the center of pad. I removed the aluminum insert which just adds weight to it so it doesn't shift around on the table. To open the mat, just remove the four screws hidden under the four rubber feet.

Great photos and very helpful.

Couple of quick questions.

You've had to cut the inner skin of the otterbox I assume because of the pressure on the hardback? I actually use a 2000mah battery so don't use the hardback at all (in effect my soft skin is in direct contact with the battery etc....) do you think this will work without cutting the soft skin?

In your second photo the wiring (red and black) coming from the receiver to the connector at the bottom. Is that a standard connector (the 5 pin one) you're using and if yes could you let me know its name or part number? Could you let me know which pins you connected which wires to?

Lastly the separate connector widget in the second photo under the wiring shot, again does that have a name or part number?

Thanks very much and if I can get this working with my battery setup and the in car mount I linked I'll post photos. Also the beauty of using a ram mount system is the mount part of the fitting can be moved very easily so if I can get this wired the next stage would be to then get a ram mount for the bike and fit a dynamo to charge the unit while cycling.

I love dabbling!!

I'm not sure if this will work with simply a soft skin, as the receiver mounts to the hard shell. Without this, it would give the electronics too much movement (flex) and possibly do damage.

I used all the parts off of the Droid X Powermat cover, including the 5-pin connector. I did however cut and resoldered the red and black wires to shorten them for a cleaner install. All wiring locations are identical to the factory Droid X wiring.

The little connector is also from the Droid X piece. It has been trimmed a bit to fit the Otterbox USB opening.

That makes it much clearer, thanks.

I didn't make myself too clear in my earlier question. I'll be attaching the powermat receiver to the hard outer case of the Case Mate tough or the Hard Outer of the Otterbox (more likely the case mate TBH). Then fitting that over the silicon skin on the phone. What I should have made clearer is due to the larger battery the phones original hard case back is not used at all. So in effect.....

Normal Standard Setup.

Phone --> Battery --> Original Hard Back

Normal Case Mate Setup

Phone --> Battery --> Original Hard Back --> Case Mate Silicon Skin --> Case Mate Hard Outer

Normal Extended Battery Setup

Phone --> Extended Battery --> Replacement Hard Back (Supplied with Battery)

Current Extended Battery Setup with Case Mate Tough

Phone --> Extended Battery --> Case Mate Silicon Skin --> Case Mate Hard Outer

*** Proposed Setup ***

Phone --> Extended Battery --> Case Mate Silicon Skin (uncut) --> Powermat Receiver --> Case Mate Hard Outer

So I think my question is how thick is the Powermat Receiver and do you have to cut the silicon skin to mount it in a 'normal' setup?

Ive just done a couple of Powermat mods myself;

The first was to use a fairly cheap 'external power pack' for the GS2 off the bay, mated to a hacked down Powermat receiver off one of the blackberrys. This has the added bonus of having the micro usb plug already built into a custom case for the GS2, and with a little bit of teasing apart, all the wiring can be done inside the case, making the end result look almost like a custom GS2 Powermat back.

The other mod was done just because I got an ipod (ptui) charging dock supplied with the Powermat travel base that I got from the bay. This had the ipod plug removed and replaced with a micro usb plug, all moulded into place with a custom seat made from 'Polymorph' (plastic granules that melt in boiling water). So I now have quite a nice desk dock that I can use at the side of my bed, upright, so I can see the digital clock that I run.

The external power pack mod looks great - did you remove the battery from the power pack or does this also get a charge from the power mat?

Any chance you can upload some pics of the process as I want one too

The battery case/power pack retains the extra battery (but be warned, it's not the 2200mAh that the seller would have you believe, but rather one of about 1000 mAh capacity), so the whole lot will charge with the phone in the pack.

Slightly reluctant to open the pack up again for photos, as I used a big blob of silicon sealant to keep everything secure on rebuilding it.

The power mat adapter was trimmed out of one of the blackberry power mat phone backs, they only have two leads out, so easy to check positive and negative, then a bit of soldering with some fairly fine wire into the back of the power-pack connects it together, with the wires fed through a small hole drilled in the power-pack case, and soldered to the appropriate pins on the micro usb connector. The power mat adapter is secured to the power-pack case with more silicon (I had some black stuff lying around).

Thanks Phil - I've got all the parts except the external power pack which is on order. I'll go through this and see if I can put a video together of the steps. I really like the concept of wireless charging with a battery backup as well!

Hi guys, im pretty new to the forum as i just got a SGS2 and i was looking for powermat mods when i came across this post, very cool stuff and a awesome job to say the least, i wanted to something similar and i just wanted to know if its possible to wire the powermat receiver directly to the USB port(sorry if this has been asked before). Any help and advice would be welcome

Thanks in advance
