Place the receiver onto the phone battery. Make sure the contacts match precisely before tear the sticker off. 2. Peel the double sided tape strip, line up the contacts with the receiver contacts on the phone, and stick the device down to the phone's battery. The receiver contacts have gold-plated 'bumps' to ensure good connection to the phone. Double check to make sure they are lined up right. Then put the back cover back on the phone. 3. To charge- drop the phone on any Qi compatible charger pad and walk away. That's it.

I bought the adapter to work with a Qi wireless charger for my Galaxy s3. As a clumsy person, I use cases for my phone of the *ahem* industrial variety. I break phones, I drop them, I drown them. I use strong protective cases.

The adapter slipped under my stock backplate of my phone. It was very easy to put in place, but the "sticky" strip on the adapter wasn't sticky. Doesn't matter with how tight it is under the backplate of my phone. The problem is that it makes the back bow out slightly, so it's not as sleek as without it. Since I keep my phone in a case, it didn't matter at the time.

The phone fit wonderfully in my Otterbox Defender case that I have for my phone. The added bulk didn't affect the fit of the case at all. The problem that I found was with my new LifeProof case. The LifeProof cases have a clear back to show off the color. The added bulk under the backplate caused the clear portion to rub on the back of the phone, creating a grey area. PURELY cosmetic, but this case didn't fit as well as it could have because of the extra bulk.

Pro:
-WIRELESS CHARGING!!! YAY!
Con:
-Bulky under stock backplate
-May cause certain cases to not fit

This is a huge improvement to my Sprint GS3.. I jacked the micro USB port to where I couldn't charge the battery anymore.. After about a month or two of constantly charging an extra battery via an external battery charger I finally found this and a cheap power mat like device (RAVPower Wireless Charger Charging Pad Qi-Enabled USB Charger Phone Charger...) and can finally keep the battery in my device!

Install was simple, and for a couple weeks I used this without peeling the adhesive backing and sticking it to the battery. After weeks of use and testing I decide to attach it to the battery by peeling the little tape cover and refitting it.. this was a mistake.. The adhesive is but a strip and it seems to cause some tension in the rest of the pad material, enough so that the little piece holding the contacts lifts ever so slightly.. As a result the two contacts now frequently get lifed off of the phone contacts on the back of the phone, stopping the charge from occurring Will see if a little electrical tape over the contact helps.

Nice product, I find that the added bulk is not apparent once the cover is on. The phone cover does fit a bit more tightly, however I have the silicone case, and cannot notice a difference at this point. I would only suggest that perhaps the item came with a picture of the location for the prongs, it took me a couple of tries before I figured out where it went exactly, though I could just be less technical than I think I am.

The product is exactly as advertised. It will take your S3 and make it compatible with wireless charging.

It takes about 5 minutes to set it in correctly and snap the cover back on. As stated, the factory cover will fit perfectly on the back. However, while most people have said they don't notice the hump, I do. It's not a game stopper by any means. But it's clearly there. I used to rest my phone on speaker on my keyboard and now it won't sit there anymore. It slides away. Kind of annoying, but not the end of the world.

The phone can get hot while charging, but I'm not concerned about it at all.

My major gripes are that it doesn't always make that 'ding' noise when first placed on the charger. Whether that is an Android issue or a device issue doesn't matter, it hinders the overall experience. Second, along with the ding, it stops charging and starts charging throughout the night, so sometimes it dings several times in the night, and it's loud enough that it can be heard and/or wake you up. This can be fixed by turning notification volume off at night, but, once again, it's about hindering the overall experience. (Just for reference I ended up making a Tasker setting that fixed the problem)

In the end, do I like my purchase? Yes, the product does what it claims to do and the price was really good. However, understand that wireless charging isn't exactly wireless, inductive charging is the better term. Sure it's nice to just lay things down, but then again you have to be pretty exact with your placement. When furniture or cars start to come with built in charging pads, then this will have a lot more tangible value.

I purchased this to use with my Samsung Galaxy S3 and a Tylt Vu wireless charger. I didn't really think it was going to work through my case, but it did. I've only had it for a short time, but it seems to charge just about as fast as the wired chargers, and It so much more convenient. It does add a little bulge to the back of the phone. I really had to push to get the back on the phone and my Seidio case bulges just a little.... but I all works great.

Love this! My charger port stopped working and I thought I'd need to replace it or get a new phone. It works flawlessly and I didn't have any issues with putting the back of phone on. It doesn't have a bump or bulge and I was still able to put my case on without any issues. I'm using it with the Qi-infinity portable wireless charger powerbank 4000 and it's working perfectly!
