I know nothing about qi or wireless charging, so don't laugh if im asking too much but I just recently bought a Kenu Airframe for my car, and I love it! Very minimal. its nice. I was wondering if its possible to make your own qi charger, and whats the smallest it would have to be for qi devices (such as nexus 5) to successfully charge to it? I am planning a project soon to install a charger, and Bluetooth receiver inside my dash in my car, and so I wont mind hiding the internals for a qi charger on the inside of the car if its possible. My idea was something almost as small as those nfc stickers, but for qi charging, where the actual charging part could be the slim "nfc sticker" size, with the actual qi parts hiding under dash. is this possible?

look at a Qi charger teardown
the circuit board probably contains voltage/current regulation stuff along with other stuff, can hide it anywhere
you'll simply need to miniaturize that coil, probably similar to how NFC tags look like... there is some current output, range and efficiency relationship on how you choose the coil size, material, length, radius etc

jesus, that's all there is to it!? this is exactly what I was hoping for! Would it be safe to assume nearly all qi chargers are built similar then? if that coil is any indication, you just might be right. I have a feeling though that the coil is that big for a reason. My guess is smaller might reduce power output, but if its the same concept, ill pick up a cheap charger on ebay to tear apart and play with, just to test it.
Here is the Kenu Airframe for anyone interested:
http://www.kenu.com/products/airframe
if you like small mounts, this sucker is really well built. price might be a bit much for some, but believe me, its worth it.
my idea is to use the small center "Kenu" plate in the middle of the mount for qi charging. One could make the coil somehow on the airframe, possibly in the size of a NFC sticker, and have it wired into a micro usb port on the back of the airframe mount. then on the qi charger size, where the coil is, wire that with a micro usb cord, and simply attach the two cables together. This would allow for any possible adjustments if you wanted to move the mount around.
EDIT: hmmm, a quick google search found this:
http://www.mouser.com/new/Wurth-Electronics/WE-WPC-Coils/
is qi charging really just a basic charger, just with a magnetic inductive coil instead of micro usb cable? is it really that simple?
The coils are specified by the Qi spec. i.e. you can't just use an arbitrary loop of wire. But, it should be relatively trivial to break open a charging pad and put its guts in a new housing.
Working from scratch, however, is complicated and fraught with peril. You'd have to get a chip (like IDTP9036) and wire it up. And no, actually "wiring" it won't work, you'd have to make a circuit board for it to live on.

well, what I mean is, can you essentially use a regular wire, inbetween the qi coil, and the qi charging component itself? in the link provided by paperwastage, it looks as though all the qi charger itself basically is, is the qi component hardware itself, with the qi compatible inductive coil soldered in. by that concept, I am asking if you could TECHNICALLY add a regular wire between the coil and components, to essentially extend where the actual coil itself can be placed and used?

You could likely add small extensions to the coil. Though, I don't have enough experience with them to know exactly how much. Personally, I would be wary of adding more than an inch or two to each end. However, you could always experiment and see what works...
Qi help
the distance between the coil and the output board, is going to effect how much power is lost internally.
the size of the coil, the wire size, the wrap (basically anything that affects the field strength) will effect the efficiency.
you'll note alot of the Qi pads out there use 2A draw to power them, but only transfer power at between 500-1000ma....and they only guarantee the lower limit. (i'm guessing because of production variations, like how accurately the coiling is laid down, whether the copper wire had high or low contamination the day it was drawn, etc)
this is where knowing the Qi spec, and tuning your antenna coil comes into play.
all that being said, GL !
I was doing some reading here and there, bought a few cheap qi coils and pcb boards. I was trying to request a sample of TI's new PCB board/coil that does not require magnets(so we can continue to use NFC, and possible compass issues.), but when I tried to request a sample their website would glitch out, may try it again sometime soon.
Did you get anywhere with this? I am trying to extend the distance between the PCB and coil and am unsure of what cable to use.
So I'm looking into the possibility of making a wireless charging solution on my own. I have lots of wireless chargers at home, work, in the car, and I would really benefit from getting wireless charging working.
I took a USB Qi charging coil and soldered wires, which I then attached (well, just touched ) to either end of the magnetic connector, and it worked.
The difficulty I'm facing is, how can I keep these wires touching the magnetic charging port semi-permanently without doing anything dangerous like attempting to solder it directly.
So I'm wondering if anyone has any neat ideas of how I might rig this up. Any ideas would help a lot! If I come up with something good, I'll make a guide so others can do it.
You could try to get someone to 3D print a side piece similar to the one on the Z3 wireless charging case from sony: http://www.sonymobile.com/us/products/accessories/wireless-charging-cover-wcr14/
Have them leave chambers to run the wire through.

I've been thinking about making my own wireless charging case similar to the sony branded case but using high quality leather, and an oem qi charging circuit with a 3d printed base clip with the circuit connectors integrated into the clip, just to ensure constant connectivity.
just looking into prices for scrap leather now.

Have you tried tape? It would be covered up by your case anyway, right?

I've thought of tape but I've yet to figure out a way to tape it where it will definitely stay in place.
I might be able to get a case that would cover it, but my current cases have holes so that magnetic chargers could be plugged in.
I've decided to try using copper tape to connect a Qi coil to the magnetic dock port. I'll see how it goes. Hopefully it will be as easy as I'm hoping it will be.
So I finally managed to make it work. Unfortunately, I had to solder.
I gave up with trying to line things up just right and keep it in place, so I just soldered a Qi receiver to the magnetic charging port, wrapped it around to the back of the phone, and fit in a case. It charges wirelessly now, so I'm happy. Unfortunately, I don't know if I'll ever be able to clean it up in the future if I want to sell the phone. But to me, wireless charging was super important. I was also able to continue using my Z1C battery case which uses the magnetic port, so I'm pretty happy with the end result.
Pics?
it's ugly, but I'll put up pics when I get a chance.
Pictures as promised. I had been concerned adding this might block NFC, but NFC works just fine. Obviously, magnetic charging cables don't work (but a Z1C charging case I have does.)
It adds some thickness behind it so the case doesn't fit quite perfectly, but well enough to stay on. I didn't have thinner cables, but having some might have been able to decrease the thickness. Also, I'm not necessarily good at soldering, so I just did what I could.
But I can charge it on my bedside table and in my iOttie Qi dock in my car, so I'm cool with it.
hmm not pretty, but i guess it works. how is the charging speed?
you should be able to clean it up fine if you use some solder wick.
Awesome job!
Can you please give us a link for the receiver?
All I can find are with usb
ugly doesn't even start describing it... seriously, you ruined that phone. You could've cannibalized a 3rd party docking station instead
duraaraa,
Thanks for blazing this trail for us, mighty brave to solder to your phone like that! Now that you've had this set up for a few weeks, is it holding up ok? I'd just about give my left nut for an actual phone case that simply has a wireless receiver built in and taps into the magnetic charger pins, but I doubt anyone will ever make one since (I believe) the Z3C is discontinued. I mean, they make those giant external battery packs for the Z3C that use the pins, so why not a qi-compatible one??? Anyway, no way I'm soldering to my pins so I'm basically trying to mold a connector out of epoxy that I can squeeze between the side of the case and the pins. (Basically I pushed one of my magnetic cable connectors into a clay bar and filled w/epoxy.) It's still drying so I have no idea if it's feasible at all, but wanted to pop in and say thanks for the inspiration.

Not good I'm afraid my friend... My first attempt (trying to mold a connector out of epoxy using a clay mold) failed, the thing came out looking like a chewed up piece of gum and just wouldn't work. My next attempt involved slicing up a couple of cheap magnetic adapters and cables to try to trim down the connectors to something reasonably sized, but they become really brittle when you cut them that thin... Unfortunately, I think it'd take someone with some type of plastic molding equipment or maybe a 3d printer (that is capable of making really small, fine-detail parts) to make this thing. I'm still disappointed that Sony makes a wireless case for the Z3, but not the Z3C, but I've also come to realize that the Z3C has such good battery life that maybe I don't really need such a case. (I come from a long line of Nexus, HTC, and Samsung devices so I've become somewhat of a charging addict!)
tl;dr: Just enjoy the Z3C and use the handy magnetic dock for overnight charging.
just looking at the magnetic connectors on the z3c I think there might be a way but it'll add a couple more mm to the height, would need to get someone with a 3d printer, but if the wallet is made of leather and is inserted underneath, with the qi wireless pad, and two wires made into connection terminals which would then clip onto the phone so a solid connection is made between those terminals.
Just to answer some questions, it's held up. I think it's fine -- anyone desperate for Qi should just bite the bullet and solder. Charging speed is similar to really any other Qi-charged device.

Sorry my response is so late!
It's the USB type. I un-soldered the USB ribbon and soldered a wire for the two connections.
So you would want to buy the USB version, I think.
Look into copper tape. I attempted this a little while back but I think my charging pad wasn't powerful enough. What charging pad are you using?
As we all know, the new Zenfone 2 is missing wireless charging capabilities, however there are multiple solutions to enable wireless charging on basically any phone.
Example is http://www.amazon.com/BEZALEL®-Wire..._1_4?s=wireless&ie=UTF8&qid=1432149451&sr=1-4
It is a cover with a Qi receiver built in, which connects to the charging port and it also provides an independent micro usb port as a part of the case.
The absence of wireless charging in Zenfone 2 is a deal breaker for me ( don't judge) and as soon as an appropriate case is available, I'll get it and the phone as well.
Please post your findings here.
Would love to use wireless charging but using a cover like the one posted is out of question.
I love the slim form and feel of this phone. so i will have to live without QI and other solutions.
This will occupy the mUSB port but would probably be the best current solution.

That's pretty cool. I like wireless charging because I'd rather not wear out my micro usb...but that setup kinda marries you to wireless charging all the time. I'd have to rig up wireless charging in the car and at work...not just at home. You use something like that?

Not sure if I'm going to stick with the ZF2, so I haven't gone out and done all that yet but qi adapters are pretty cheap now for both home and car. How effective some of the car ones are though are another story. iOttie has two models out now that look promising for the car.
There may also be the possibility of placing those adapters into a separate case just meant for wireless charging... remove the case if you need the mUSB port.]
Or... if they do release new back covers... get one that you install the qi adapter in and then one that you won't have the qi adapter in.

what to do :'(
Here's a teardown: http://www.myfixguide.com/manual/asus-zenfone-2-teardown/
You could solder the DigiYes posted earlier (http://www.amazon.com/gp/product/B00HI8JYFE) onto the usb board. Or you could probably just jam the wires into the connector for a non-permanent solution. The pictures of the DigiYes are a little conflicting, but if it does have leads for the data pins, you'd be best off omitting them (you'll be limited to 500ma qi charging).
This is of course assuming there's enough space to wedge the DigiYes between the back cover and phone.

Which goes back to my point. Why did Asus purposdely omit to include QI/wireless charging pins on the back? It would had cost them hardly anything extra at all, and users could just have changed back cover to get wireless charging...
That one http://www.amazon.com/BLUBOON-Unive...2630&sr=8-2&keywords=qi+wireless+charger+1000 is 1000mA, if it does make a difference. But a case integrated receiver would be much better solution, if ever.

I bought that model. I have a Qi charger (used with a Nexus 5) hooked up to a 2A USB Adapter, and it barely charges the Zenfone. I do not recommend. Maybe a 2A receiver would work better.
It's ridiculous.... why did asus decide not to offer a wireless charging solution similar to the previous samsung galaxies/lg.
Have the pins for charging on the back, and let the user change the case to a qi receiver case or add a qi receiver pad inside. this is honestly the only thing that disappoints on this phone (((((((((((((

I just received mine and there is enough space in the back cover for the receiver to fit in, albeit with a small bulge. It does show my phone as charging even when just held up to my Moto 360 cradle; whether or not it's charging, however, I have no idea.

Thanks for trying. Did you actually solder or just plug it in the usb port? If you plugged it in the usb port, does the cover close without damaging the cable?
I'm asking because if that works, we could potentially design a slightly thicker but hollow back case that could hold NFC and the wireless receive without unnatural bulges.

Yeah I judge, wireless charging its just another feature. A small battery, a slow processor or low memory now that's a real deal-breaker since your phone wont last a day, apps will run like hell and you will always have to micromanage just for things to run properly.
I'm way more pissed off at this phone not having a removable battery, not just because its a real deal-breaker during travel where I will be forced to lug around one of those brickish power banks but because Li-ION batteries have the lifespan of a mosquito. I already had 2 phones like that and the result was always a massive pain in the ass to deal with.
I rather buy a case with an extra battery than this thing
Three pins USB Board?
Hi there
Maybe some one knows, what are those three pins on the USB board, that are accessible without disassembly phone?? That should be connectors to charging instead of usb socket?
I have a qi charger built into my car. I do not like aftermarket charger added to the phone. So this is a deal breaker for me and will not consider any phones without buildin qi charger.
Looking to buy this phone and own a quick charging card like this. Is it possible to slip the card under the back cover (without a case) or will it cause it to bulge in too unsightly a manner?

The speed of charge is 350 MAH ?? Is to slowly (USB PC charge normally 550 MAH)
Hello everyone! How are y'all doing on this lovely week? I'm doing great!
I got my Zenfone 2 last week and I'm loving it, but I miss the hability to wireless charge it and especially to put it in the Air dock when I'm my car. So here I came asking for your aid!
Is there any dock like the Air dock for the Zenfone 2? I have an Air dock (1st Gen) that I bought back when I had a Gnote2 and because of the curved back and some wearing of the rubber in the dock the Zenfone 2 doesn't hold very nicely, so I'm thinking about making my own magnetic dock to put in the car.
Also, is there any way to get Qi wireless charging to work on it?
My initial idea on the magnetic dock won't even consider charging wirelessly since I plug it via a cable when on the car to listen to music/podcasts but maybe If I could get it to work, as times goes on, I would find a way to charge it wireless and get some sort of bluetooth dongle for the car.
My thoughts on a project for the dock involves using HDD magnets since they are really strong and it would make the device secure. But my concerns are if it's safe to use magnets that powerful near a phone for it's hardware and for it's battery, since s not easily replaceable.
Anyone here ever did or saw some sort of project like this? I'm possibly gutting my Air dock if the Zenfone doesn't support Qi wireless.
Any input is helpful, I'm completely open to suggestions!
There is an existing thread about QI solutions since there are no contact pins for wireless charging without some heavy modding of the device casing or usage of the USB port. As far as I'm aware, magnets have virtually no effect on the hardware except for a few sensors like the magnetometer and possibly the magnetic cover sensor.

Thanks! I'll try to find some weaker magnets to keep it in place without such a load in my mind, thank you for your help
Sure, good luck and I'd be interested in seeing what you think up.
I'd opt to use a cradle or similar holder instead of magnets. A strong enough magnet would probably add too much bulk. When looking for qi receivers, make sure to get one that has data pins (which will most likely be shorted to allow rapid charging). This one is still a reasonable price http://www.amazon.com/gp/product/B00WKWWMAM and fits well enough in most cases. It does even fit alright inside the back cover, but you're better off putting it between the phone and case. It'd make more sense to go qi all around since it becomes a hassle to unplug it..
If anything, you could save a bit of bulk by ripping it apart and removing the magnet. It does seem to severely cripple nfc though.
As for bluetooth receivers, they have become significantly cheaper recently. You could get an old bt2.1 a2dp button-less one and hide it away somewhere. I got one for $3 shipped. There are apps that can be set to auto-play on pair. For $10-15 more, you should be able to find something with buttons (back/playpause/next) and aptx support. Usually these will have a microphone as well
Whether it be an internal wireless receiver or external usb c receiver. Most external usb c receivers are at the minimum 3.9" tall which seems to be the issue.

You can get an Ultra Thin USB-C Qi Wireless Charging Adapter, and you could install it on the phone and keep it hidden and in place by getting a Razr phone case. I plugs into the USB-C charging port and the thin flat ribbon cable has a 90 degree bend to it. I used this coil adapter before on a convention smartphone years back, the only drawback is that your USB-C on the phone will be occupied by the coil. Wireless charging is slower than traditional USB-C charging.

I'm aware of that but the issue is most of these are at least 4" in height which would cover the fingerprint sensor.
Find the shortest version, and if need be you can cut it to streamline it.
The ribbon cable has some flex to it, and if you use a heat gun you can bend the flex cable like an accordion to reduce length. You could also diminish the height of the coil pack by cutting it. Since the phone has a glass back, and your "sandwiching" it with a case, there is no fear of creating a short when charging.

Wouldn't cutting it cause it to malfunction? Also, do you mean use a heat gun to fold it in half? Do you have illustrations?
I think he meant to cut the edge to make the fingerprint reader completely clear, but not to cut too much to avoid the coil, and I'm assuming he meant to fold the cable in half.
Another point besides the charging speed is the heat that the coil produces.

Just a few questions. Where can the wireless adapter in this picture be purchased (link)? It looks like the usb dongle is too long to fit properly on the phone since the adapter is shifted below the fingerprint sensor. Does this wireless adapter work good on the device without overheating?

I see this for Barbuda nut only comes with lightning connector... would need USB-C ＆ only 5v so... I would still buy one at that folds its level because I don't really care if it's fast charges because I leave the thing on the stand overnight and it may actually be better for the battery to slow charge.
I played around with this as well. I was able to trim the one I'll link below to the right size. The key is to not cut the coil, the rest seems like it can be cut without a problem. In the end I didn't like not having access to the USB-C port. But it was a fun pandemic project.

As for the one I cited above with lightning connector... maybe someone here knows how to suggest they make one for USB-C ??

I'm a little late to the party here, you can solder in a wireless coil to the inside of the phone. The best coil I could find is this 7.5W (5V 1.5A) coil. There's a 10W (9V) option, but it would require addition circuitry to use in a phone.
The external plug-in solution is by far the easiest option, but it has too many flaws: blocks usb port, protrudes too much, fragile- must be kept inside a cover to protect it, most put out 2.5-5W, and it looks horrible.
Heres the link for the internal coil. If its unavailable at the time of reading this, on aliexpress, search for "7.5w wireless coil".

And here's a youtube link showing installation. You can skip half of it. aim is to tap it to the ribbon carrying the charging from the usb.
It does require some understanding of basic circuitry and soldering... not for everyone.
Ive just bought the new Razr 2022, and will be installing it on that.
Just keep in mind that the RAZR has two batteries, and getting it apart isn't for the faint of heart.
It's also one thing to get apart, and another thing getting it back together..
Just advice, but definitely watch anything you can get your hands on before tackling, and good luck.
