Zens Wireless Charging Kit

Saw this article this morning. Thought I'd share it.
http://www.phonearena.com/news/Samsung-Galaxy-S-III-wireless-charging-kit-introduced-by-Zens_id32935
Won't be coming out until September, for about 85 USD, but at least there will be options.
Does anyone know how much the official one will cost?

anyone know how wireless charging compares to outlet powered charging as far as strength and charge time?

$85 to me just seems ridiculous for a wireless charger when the technology obviously doesn't cost nearly that much. I think even after these official setups come out that I will stick with the palm touchstone conversion if I decide I want to do wireless charging. Even if I mess something up I can buy and screw up 8 of those before I even get close to paying $85.

I agree, the touchstone cost less, but with the touchstone charging rate is only 500mAh which has slow charging time.
I'll like to see the official one first.

The Qi standard offers a maximum of 1A in low power mode but a lot of the ICs on the market (TI) only support up to 500 mA. 500mA is about half of dedicated wall charging one I believe and the same as when you plug it into your PC to charge.

I plan on modding a case to do this. I am currently looking for some schematics because I have a feeling that this was provisioned in the design of the phone.

1A is more like it,the SGS3 has a charging rate of 1A through the mains.
i'm not in a rush for one so i'll see bother before I decide.

I'm not too sure myself, but I've heard some people say it takes longer and others that say it takes just as long. I know when my husband had the palm pre and would use his touchstone it really didn't seem to be a very noticeable difference in time.

Does seem a little pricey, but would love to pick up one for my desk at work, grab and go when I go out on the floor.

It's new technology(For phones at least) so obviously they gonna rip off the early adopters, I mean I bought one for Nintendo DSI for £3 which has identical technology to what they put in that so I'm gonna take that apart and if it works just buy a cheap battery cover and stick it together.

If it is qi or compatible then the energizer charging pad will work. It is well worth the money imo. I used it with tbolt every night , before my slim, lean, toned s3 arrived. Now I just can't decide whether to ripe one of my spare tbolt qi doors apart or wait for factory s3 qi door.
For what I've seen if the palm is so easy why not use the "proper" dock and hack a tbolt or similar door.

Hopefully this combined with the Verizon version that someone posted some photos of will put some pressure on samsung to hurry up and release the official one...

Sonof the zens unit is $85 then the official Samsung one will be $100or more.

still no word on the wireless kit?

For overnight charging, this is a good thing - extends the life of your battery. The higher your charge rate, the less your battery will ultimately live. The performance of your battery overall will degrade. Slow charging is a good thing.
If you want a fast charge, just plug into a USB cable if you are in a pinch.
Also, I read in the Galaxy Nexus threads (where the Palm Touchstone mod originated) that there's a software mod they are applying to increase that rate up to be nearly as quick as the 1A charger. The same type of mod may be applicable here.

I just got my ZENS+Shield kit for the S3 that has the protective shield instead of the OEM-style backing. I'm loving it!
Previously I had been using an OEM back with a Touchstone wireless charger installed in it, but I really wanted to have my elago slim hard case that makes the buttons recessed. I made an ugly hack that made it work most of the time but I hated having to fiddle with those Palm Touchstone chargers and making it align to the magnet.
Sometimes my cat could get annoying and just nudge it or maybe the phone would vibrate enough from alerts, it would get into this "charge-discharge" loop state that can't be good for the phone, sometimes even fully lose contact. It was just not very reliable -- I found myself sometimes just plugging it into USB to get a better charge.
The ZENS wireless back fits really well and provides the backing I wanted. I wish the texture was a bit more grippy but it's not exactly slippery. It's on-par with the stock grip. It's a bit heavier and slightly more bulky than the elago case but that's because it provides a bit more protection and has a rubbery pad for some sort of shock protection.
The charger is great too. I can put the phone in just about any position and it'll charge. They even brag it'll charge if you put it on a high volume speaker in the instructions (but it may take up to 2 mins for it to "negotiate" in that case.) It seems to charge faster than my Touchstone.
It's Qi standard so I should be able to use it with any charging pad. I was shopping for a second charger but the 3-position Energizer looks much too big as does the Duracell and the single position Energizer is slanted and I've read some people have issues with it sliding off. I like that the ZENS charger is flat and the size is nice, so I ordered another.
There's one downside to the ZENS charger but I think other chargers (except the Palm Touchstone) suffer the same problem: they do not use USB as a power source. My ZENS charger uses some ugly wall-wart. Also it's a bit more expensive.

Official Nexus 5 Wireless Charger, First Impressions.

I had the tilted wireless charger already (link bellow) but decided to get the official wireless charger as well.
http://forum.xda-developers.com/showthread.php?t=2611246
Of course its a lot better made then the Chinese charger but is it better in usability and charging speed?
With the Chinese charger I was using the stock nexus charger and cable because they are much better then the cables that came with the charger, more detail in the link bellow
http://forum.xda-developers.com/showpost.php?p=50254993&postcount=116
The info you need to know is that the OEM nexus charger and cable put out about 1000-1100mA while the same cable paired with a samsung 2a block was able to push past 1600mA but not keep it there, leveling out at 1200mA. The OEM block and cable with Chinese charger puts out between 650mA and 730mA
So how does the official Nexus charger compare?
Well to start I tested the new cable with the OEM block and it was putting out just over 1100mA, so we know the cable is better then the OEM cable. Then I tested the new cable with the block that comes with it and got a steady 1600mA and it didnt drop. Now the block itself doesn't say anything on it as to what it puts out, but the charger base says 1.8a, is that what the block puts out? Regardless the block is much better then the Samsung 2a block.
I don't use a case so the phone on the charger itself puts out only a little bit more then Chinese charger keeping a steady 768mA. Now it can drop below and above that number but it really likes 768mA. So while it does have a great cable and block, if all you care about is speed then charger itself is a little faster but not by much compared to the Chinese charger.
As far as usability, I cant get the nexus charger to miss. I can throw it on and it connects every time. With the Chinese one it didn't always connect and i had to make sure i got it in the right spot and make sure, even if I heard the noise, that it didn't disconnect and was actually charging. With the nexus charger I feel confident that the magnets are lining it up and it gets a good connection every time.
As and added bonus, I have heard a lot about how you could possibly charge while vertical attached to a wall. I decided to try this and I can attest that the weak link will be the charger holding the wall not the charger holding the phone, as long as you don't use a case like me. The magnets are more then strong enough to hold the phone vertically, in fact they are more then strong enough to hold it upside down, I tried! The pad that sticks to the surface is just as strong as I've been hearing as well. I literately just slapped it on the wall and then threw the phone up and its holding thus far. I have it only a few inches above my night stand and will update if it falls, but so far it has held up to me taking the phone off and on about 50 times with no issue. I'm not sure how it would hold up as a car mount, only because I don't know how the sticky part of the base would hold up to extreme hot and cold. I image it would probably fall, especially if completely vertical.
I would definitely recommend the Nexus charger over a Chinese one. I you have the $50 then its a no brainier, it was even a couple bucks cheaper then that on amazon and my prime membership got it here on Monday when i ordered on Saturday afternoon. If you only have $13 bucks and don't mind waiting 3 or more weeks then Chinese one charges almost as fast.

I too finally went from the orb to the new charger because I wanted a vertical mount. I'm blind as a bat with my contacts out and wanted to be able to see the time on my phone while in bed. With the orb, the angle was bad and my nightstand is taller than my mattress, making it hard to see. So I got the new charger, put it on the side of my nightstand and it's holding just fine. Holds the phone great too and now I can see the time on my phone. As long as you can get a smooth, flat surface, I don't see why mounting vertically would be an issue.

just wanted to say, it did end up falling off the wall the 2nd night while charging, the charger from the wall, not the phone from the charger. A good sized piece of 3m double sided tape right in the middle of the charger fixed that and I've had no problems since.

Charger in use
Can you advise please if the Google charger cuts out once the phone has reached 100% or does it change to a trickle charge? Looking at some of the alternatives (e.g. on Amazon) I haven't found any that automatically cut out at 100% although a few mention about changing to a trickle charge. What's your experience in this regard?

I bought the official one and I must say that I'm very pleased with my purchase, Is there any apps which can detect the charging voltage so i may test my charger as well?

Have you considered using this charger in the car? From what you're saying, the hold issue seems to be the charger itself. Using double sided 3m thick tape may solve the issue.
The reason I'm curious is because I and many other previous Palm Pre users used to use the touchstone wireless charger in their cars and the phone never fell of even on extreme bumps. It was great being able to simply place the Pre on the charger and if you were lucky you could put the touchstone right in your line of sight (I have an 06 civic so the touchstone fit right next to the steering wheel, to the right. Look at my profile pic or do a search for palm Pre wireless charging in the car and you'll come up with hundreds of results and pics).
Do you think the charger's internal magnets would be strong enough to hold the nexus 5 in place while driving? Right now, I still use the touchstone as a place holder for my 5 as the internal metal discs on the 5 line up nicely with the internal magnets in the touchstone. I did modify the touchstone slightly and added magnets every 90° starting at the 45° position and then the other 3 were 90°apart from the initial magnet. I'll try to post a pic or a video of what I mean. The touchstone is not a qi charger so it doesn't charge but it certainly makes for a super convenient spot for the phone to be especially when using navigation. Also the nexus has not fallen once while driving over some pretty harsh bumps.
What do you think?

RAVPower Qi Wireless Charging Receiver Review

http://www.amazon.com/RAVPower®-Wir...F8&qid=1393455689&sr=8-3&keywords=ravpower+s3
After getting my Nexus 5 and getting spoiled with wireless charging, it was quite troublesome to charge via a usb cable when using my s3 as a secondary phone. So I wanted to get a wireless receiver to go along with the Nexus 5.
Packaging
Not much to talk about here, simple box containing the unit with a small plastic wrap inside. No frills.
Build Quality
The receiving tag is very thin, I can't compare it to others but im guessing they are all comparable. I had no problems putting the back cover on. There wasn't a huge bulge were the tag is. There is a slight bump but you would really have to be trying to feel for it to notice its even there.
Performace
Using my Ravpower Qi Charger it detected the tag instantly. There wasn't any time where I had trouble with getting the S3 to start charging. It didn't get any warmer than usual when charging with a usb cable.
I have a Diztronic case on my S3 and it charged it just fine through the case. I've tried other cases such as the ZooGue case had the same results.
Conclusion
For a mere 10 bucks, its sort of a no brainer for the convenience of wireless charging. I been using it for over 2 weeks and never had a problem with it.
You MUST have a wireless charging pad. Ravpower is offering a 20% discount on the receiving tag when you buy a charging pad with it via amazon. Details is under the "special offers" in the middle of the product page.
I recommend the Ravpower Orbit

The best deal for a wireless charging pad is from Monster Watts, sold through Vivealive (sp). $14.99, is the WiQiQi charging pad. They charge $5 shipping, first class USPS inside the US. The pad works well. Not much to look at though, but good deal for the $$..
I'm using the RavPower reciever. It works well together. What I have found out playing around with the charger, is that if you have a poor connection between the charger & reciever, you will get the on/off cycling. I have my phone in a Seidio Active case with velcro on the back to secure the phone on the Mountek CD slot car mount I use. The extra thickness of the velcro prevents good reception & I get the cycling. If I remove the plastic frame all is good. If I remove just the velcro all is good. The screen will flash once at charge start, turn off, then flash once when battery full, then turn back off. The phone will then remain on the pad in standby with no cycling.
It all works a treat, I can't wait to get my AirDock for the car to add wireless charging there as well.

Ravpower said it'd come back in stock within a week. Also, I don't have experience with any other Qi charging base, just ravpower and they've worked great for me

Qi wireless charger

Hi,
I recently bought a qi wireless charger because my charger port of the phone broke and it's too expensive to fix.
Anyways, yesterday I left it for 2 hours the % went from 49 to 90 which I was quite happy with but I let it charge over night and it only went from 34% to 50%.
I am rooted and on AOSP.
I check the wireless current and sometimes as soon as I put it on the pad it's 1000ma but then it keeps dropping quick to 100ma. The pad as an output of 1000ma.
Csn someone tell me how to fix the slow charge. Thanks

you're probalby not lining it up properly. that happens when you've misaligned the pad to the charger. find the sweet spot and just remember to place your phone there the same way.
if you're handy,you can probably also come up with a cradle of some sort so the phone falls right in place everytime.

I placed mini rare earth magnets under the phone's back plate, just 2 on the top area, and then 2 on the Qi wireless charger so the phone aligns perfectly with the charger, and gets the best charge it can get.. Also I opened up all my Qi Chargers and used my Dremel to remove all the extra plastic, as much as I could to remove any kind of resistance or space between the Tx Coil and the Rx Coil.. I tested the best place they could be aligned with a Multi Meter, and then added magnets.. Works like a charm.. Its a pain in the ass, but mine works out pretty well. I didn't place the magnets on the inside, I placed them on the outside of the charger.. Works well

thats what I purchased..

uh wow... that's seriously overkill but sure.. you can do that..
although i wonder if putting magnets that strong in your phone will mess with your gps and magnetometer.
i would say a small plastic cradle or creating little edges on the transmitter so the phone just physically falls in would be an easier and safer alternative that using a dremel on your receiver.

I would of thought the same thing, but it has given me zero problems when the magnets are set up top.. HOWEVER, when I tried to place 2 near the bottom, it caused all kinds of problems with USB charging and my phone locked up a few times... I'm glad the damage wasn't permanent.. I used my Hotglue gun to hold them into place, the magnetic field caused a short in the Gluegun and it EXPLODED in my hand.. I was lucky enough to drop it right when I heard the sizzle and BANG.. So when playing with strong magnets.. Be careful.
Edit: I also have an external case with the same type magnets, and even with the case on, it doesn't give me any issues, at least any I'm aware of.. I made a magnetic mount on my desktop pc, just for kicks.. But since the case is metal, I can't put a Qi charging coil on it.. Now that would be neat..

yeah.. that's dangerous in general. I honestly would not recommend anyone to do what you did considering you almost ended up with stuff blowing up un your hands.

The idea behind Qi is simple: all devices with the Qi logo will work with all Qi chargers. That’s it. No need for separate chargers, no need for cables, and no need for adapters when traveling. Qi is a global standard – this means that your device can be charged wirelessly wherever you are.

Budget magnetic charging cable

I want to buy a magnetic charger and I live in India and very low quality cables are available on the local websites. I have looked for cables on eBay.com which ship to my location but I don't know which one to buy. I need your opinions. My maximum budget is 12$(incl. shipping).
The WSKEN Cable is available at my location. Is the cable worth buying?
Thanks in advance.

I got wsken magnetic cable, and its build quality is fine, but magnet is not that strong - its even weaker than another fake original sony cable i got. But if you just use it to charge your phone without using it, it can do the job.

I wouldnt recommend one with a very strong magnet. There have been some horror stories of the storng magnet PULLING the phones charge port completely out. I got a fairly weak one from amazon.
http://www.amazon.com/gp/product/B00UOVZOBK?psc=1&redirect=true&ref_=oh_aui_detailpage_o00_s00
Fits perfectly with my Cruzerlite TPU case. I even have EXTRA room for clearance. Magnet isnt the strongest which makes me happy as I only charge at night when I'm sleeping as the phone lasts through the day for me.

Yup, it happened to me. I use a Magnector adaptor and it is very strong, after a while the whole connector came off as there was simply a VERY thin acrylic glue foam tape (VHB ?) holding it and keeping water off. By thin I do not mean the thickness but the actual long side surface
The good news is that the connection with the internal PCB board are spring loaded, so I put it back in place and tested it then used a needle to put some cyanoacrlylate glue to hold it, it never came out again and the phone still look ok. Now I always try to removing it with a twisting motion just in case...
It is hard for me to understand how they can claim waterproof and use such thin gasket but I still like this phone a lot!

hmm dont think I'll be getting a magnetic charger any time soon then if it comes off that easily. >_<

It's just the Magnector adapter that seems to do that. None of the others are strong enough to pull the connector off of the phone.

I just bought an OEM one from aliexpress for only $2.71 US. btw you only save .03 if you use the mobile app
http://www.aliexpress.com/store/pro...a-Z1-Charger-Adapter/1775016_32429292298.html

I also have a generic magnetic charger. The one with a circle blue LED in the part near the magnet. I found that it charges slowly compared to the OEM usb cable that came in the box. I used the same OEM charger for both tests.
Charging via magnetic cable is roughly 60-70% of the speed of normal USB charging. Is this just me that I have a low quality cable or is it really that much slower?

I tried two Magnetic cables but they don't work on my Z3 Compact because pins are not aligned with phone and charging not working probably because there is no contact. Actually i got one with LED indicator to work several times but on slightly move it stops charging and it is hard to get it to charge again so I gave up on these cables.
I bought original Sony DK48 Dock and it's working out of the box. Only issue is that I need to remove protective case before charging because with it phone won't fit in Dock. It almost fits so I'll probably try to modify larger adapter so phone can fit with case...

I received my DK48 dock and magnetic cable from Ali Express and they both work great. The charging cable ($2.71) matches the pins perfectly so doesn't appear to be a knock-off. I have a Devilcase bumper and works with the DK48 dock also with the case on--just attach the included back rest. It takes me a few times to get it aligned perfectly to charge but works.

I'm using this cheap one and it works great for me. Magnet is ok so you can even move your phone as long as the cable is parallel to your phone.

I'm have WSKEN X-cable Easy Version, and it's great.
You can also try WSKEN X-CABLE DOUBLE METAL which has a charge indicator led.
Both cables charge my device faster than original Xperia Z2 charger and magnet is not too weak/too powerful.
Check WSKEN website for details.

I've tried several magnetic chargers and adapters and always facing the same problem, too weak magnet and if the phone is moved even an inch the cable falls off. Finally I got WSKEN X-CABLE for 7$ and that did the trick, everything works great including fast charging. You can literally hold your phone up in the air by the charger. And no, the magnet is not too strong as described in previous posts, with a slight pull it comes off without breaking the phones charging port. There is even a little plastic widget included to attach the cable into the right position angle and you can perfectly use the phone while charging.
