Toyota is going to start selling avalons with qi chargers.

http://www.engadget.com/2012/12/19/toyota-2013-avalon-limited-packs-qi-wireless-charging/

I'm hoping that it would be a sign of 12v qi chargers coming soon.
[Nexus 4 Accessories] BK553:
Sign me up as well, my paypal is ready and waiting.
[Nexus 4 Accessories] nm3th:
Wait, 7W at 12V or 5V? That makes a big difference, 12V @ 583mA or 5V @ 1400mA. Otherwise, there won't be enough current to charge the phone with screen on, GPS and BT.

[Nexus 4 Accessories] James BlackHeron:
This is exactly what I'm thinking too. I wonder how long it will take for RAM to come up with an official one of these that is integrated to snap into this mount? Probably when Qi charging becomes more common on new phones. But eventually I will see it happening. It's a no-brainer that it will come eventually when there is demand for it but I doubt it will be before the end of 2013 at the earliest.

Please add me to the list too. I know You are not getting alot of units, but still if you get more, please add me to the list for future shipments.

Wow, this thread really blew up!

Glad to see everyone is interested in it, and that I had found it. I'm not sure if Narcopolypse knew about it before I made the post, but I'm glad it's generating interest.

I got a tracking number from Moon a couple of days ago, but I'm not sure how to track it. it's an EMS tracking number, from South Korea I believe.

Anyway, I'll try to put the charger through it's paces when I receive it, and hopefully we'll have an awesome solution.

If there's any tests anyone would like me to do with the charger when I receive it, let me know.

Currently I plan on these tests.

Charging with screen off, no apps running, GPS off

Charging with screen off, Spotify streaming music via mobile data.

Charging with screen on (lowest brightness), Spotify streaming music via mobile data.

Charging with screen on (lowest brightness), Spotify streaming music and GPS turned on with native Navigation app running

Charging with screen off, Spotify streaming music and GPS turned on with native Navigation app running

Charging with screen off, only GPS turned on with Navigation app running.

I'll test each scenario for 20 minutes and record initial battery percentage, and final battery percentage over the 20 minute interval.
[Nexus 4 Accessories] Russ.Dill:
It's power that counts, not current. 7W is 7W, regardless of voltage.
[Nexus 4 Accessories] ikke008:
I'm interested! Put me in for one!
[Nexus 4 Accessories] nm3th:
Power = Voltage * Current

7W = 12V * 0.583A

7W = 5V * 1.4A

Is the site not working for anyone else in the original link? I'm trying to take a look but I'm pretty sure I'd want it!
[Nexus 4 Accessories] isangelous:
Most QI transmitter circuits run at higher than 5v (e.g. TI use 12v), and will pull ~600ma max as above. The process acts like a transformer, so the voltage at the transmitter and receiver can be different, and the current will scale accordingly. Obviously a step converter can be used if required too. Note that the QI receiver in the phone doesn't actually output 5v, it outputs ~4.2 (it charges the battery directly). In the case of usb charging the current would be only slightly lower at 5v than 4.2 because most of the difference is lost in the conversion.

narcopolypse says this QI charger pulls around 5W from the car with current phones, so that is about 3.5W to the phone (at 70% efficiency) or about 800ma to the battery. I expect that would be enough to power the screen/gps and charge the battery (slowly!).

As I haven't seen the charger the only thing I haven't taken in to account here is any losses generating the voltage for the transmitter. I doubt the cars 12v is stable enough (it can vary from about 11v to 16v), and they probably have a step converter of some form.
[Nexus 4 Accessories] delrazor:
As long as it can sustain my current battery level when I place it in the dock, I'd be happy. I've seen a few instances of placing a phone on the charger, but the charger not having enough to keep the phone up, and it actually still drains the phone slowly. Nothing worse than having the phone on charge and it dying on you after using it for GPS.

If it can charge up from current level! With things like GPS and music running, all the better to me.
[Nexus 4 Accessories] delrazor:
Just received my package from Korea!!!!

Will have pics and initial thoughts soon!
[Nexus 4 Accessories] runningwarrior08:
That's awesome.

Were you able to order without the sleeve as planned? Or did you pay the full 80 shipped?

I am tempted to order it straight from them pending your thoughts.

Also what is the total time it took to arrive?

Thanks in advance and I really hope it works well.
[Nexus 4 Accessories] delrazor:
He sent me the tracking number last week, so about 1 week, but that was expedited shipping.

I worked out a deal with him to test the unit and review it for him with the nexus 4 and only paid a fraction of the amount. He sent two iPhone sleeves as well, but said there would be an option to get the charger without a sleeve, they just don't have a set price yet.
[Nexus 4 Accessories] tehrules:
Stick me down for one please!

I need a car holder that fits the phone, plus it means I can get rid of that hideous hiss from car chargers (that my last phones didn't suffer from!)

I'm in the UK so am happy to pay the extra for shipping!
[Nexus 4 Accessories] delrazor:
Sorry for the radio silence. Today's been hectic with the holiday tomorrow. I have yet to test the charger but will be doing a test on a long drive in about a half an hour. I'm hopeful!

Here's a pic to sate anyone's needs. Will have plenty more soon.

http://i.imgur.com/KRswQ.jpg

Build quality is really nice. Feels rock solid. The phone, naked, slips in via the top almost perfectly. With my OEM bumper on, its a little tougher and I need to pull one of the arms over a little and slide it in from the side.

Holds it nice and secure though.
[Nexus 4 Accessories] narcopolypse:
Sorry I haven't been on over the weekend. Been out of town visiting family but I did get everyone on the list.

Here's the low down.

It looks like I will have the first shipment in 2 weeks. Retail price will be $50 but I will be discounting XDA members price as much as I can.

I will do international shipping so don't hesitate to have me do it for you.

And Merry Christmas!

My initial test showed a gain of 6-7% per 20 minutes running Spotify streaming on mobile data and screen on constantly at lowest brightness. I'm going to run a proper test tomorrow when traveling to family get together for the holiday. Will have more pics and hopefully a video soon.

[Nexus 4 Accessories] Acuity:
Some people were joking about testing such a device in harsher climates, but how would this really work out?

I live in the north east where it can get very cold in the winter, and we're actually expecting about 12" of snow tomorrow night. During extended outages, I often rely on my car charger to charge my phone while I go to get food or whatever, so having something dependable is important. I suppose I could keep the plug-in charger in the glove compartment, but I like to keep things tidy. Also, would it not be good for the device to leave it out in the car when it gets sub-zero in the winter or 100+ in the summer? I'm not someone who is good about bringing things inside.

Any update on the trip and outcome of charging? :) Hope the holidays were great!
[Nexus 4 Accessories] delrazor:
I ran into some hiccups during t e trip and I'm now determining if they were user caused or charger.

Basically it would go on charge, the little light on the charger would turn red(indicating it is charging) and the phone would show it is also charging.

After about 2-3 minutes, sometimes 5 minutes, it would all of the sudden act like its not charging anymore. The phone showed discharging and the light on the charger was green. The whole trip home I would unplug and replug the charger into the lighter jack and it would restart charging, then about 5 minutes later it would turn green and not charge again.

Today however, I just went on a lunch run, and left it on the charger with the screen off the whole time, and the charger stayed red and charged the whole time for 20 minutes.

I'm thinking I had some sort of disconnect with the coaxial power plug in the bottom of the charger. I haven't mounted it yet and just had it on my dash.

I'm testing things for the next hour and will get back with more pics and conclusions.
[Nexus 4 Accessories] rpcob:

[Nexus 4 Accessories] delrazor:
OK, so after an hour of testing with different scenarios and different temperatures I've got a little more data.

With the screen off, only streaming Spotify, I get about 3% charge in 5 minutes. Screen on at full bright brings that down to about 1-2%.

Here's where things are getting sticky. The charger turning off during my drive last night seemed to be intermittent. What I think was happening is one of two things.either the charger gets too hot, and it shuts down charging, or it can somehow tell that its not pushing the charge higher, and defaults to "done" mode.

I setup a test running need for speed: most wanted and let it just play out the course without interacting with the game. As the phone played through, about 2-3 minutes into playing, the charger would go to green and stop charging. I could slide the phone out and then back in and it would attempt to restart the charging and after about 10 seconds it would go to green again. I took the phone out and it didn't seem TOO hot. I've felt hotter after longer play periods.

I tried a few other tests, running the game while blowing cold air over the charger from my AC vent and it seemed to do the same.

I went back to just streaming Spotify and having the screen on and it charged fine for another 20 minutes with no hiccups.

Last nights trip was performed with Spotify streaming, GPS navigation going, and screen on. That caused charger outages after about 5-10 minutes.

I can't be certain if its caused by temperature or if its sensing the charge is not pushing fast enough and just defaulting to a non charging mode. From what I've learned, the charger DOES have a sensor that will stop the charging when the phone reaches 100%, so its not out of the picture that this could be the case.

I'll continue to test and bring my results when I do.

I'll also contact Moon and get his opinion on what may be happening here.

He mentioned that the other charger, the AutoPad, has a higher amount of power to the charger plate, so it would possibly alleviate this behavior.

I'll keep everyone up to date as I can.
[Nexus 4 Accessories] neotekz:
which charger did you get? i thought you had the autopad since that's the only one they have on their website. try a battery monitor app to check if it is the battery getting too hot. I've had problems with my car chargers in the past on hot days when my phone gets too hot it would not charge properly, as in not give enough current to charge the phone with the screen on.
[Nexus 4 Accessories] gmac24:
Can you please add me to the list. :D
[Nexus 4 Accessories] B1663R:
Really appreciate your testing and will keep watching for your updates. Looks like 2013 is gonna be wireless charging time for many of us.
[Nexus 4 Accessories] delrazor:
Moon ended up sending me what they call the CarPad. Its a lower Amp push and a little smaller he said. He's going to send me what they call the AutoPad soon. They had to work out some kinks with audible interference when using it from the lighter jack.

Here's his exact email to me about it all. The AutoPad will push 1A to the charger, which may get better results than what I'm getting.

_------_-------------------

So so sorry for late shipping.

I will ship them tomorrow but It will be sent only CarPad with iPhone 4S case. For sending the AutoPad, It will take a while to get a error-free charging pad. As soon as we set up the new module for this, we will ship it also.

The reason for late shipping was that we've find recently that most of car is Okay with AutoPad *but a few of car is not able to response due to the some high pick noise from the cigar jack power.*

Please may I have your direct telephone number? It's better to fill in your phone number at EMS delivery sheet.

I hope you test CarPad with Nexus 4 and also with iPhone 4S charging case which I send also.

When we checked the charging speed with iPhone 4S while navigation "on", it was 4% per 10 minutes. with navigation and bluetooth "off",

it was 6.5% per 10 min, which is well enough to endure the power loss due to high consumption of GPS navigation and bluetooth even block box.

Once again, I am sorry for late shipping and thankful for your patient.*

Best regards,

Moon

-----------------------------

AutoPad is able to grip large size phone such as Galaxy note 2.

It can be adjustable both side.

CarPad is good for holding the size like Nexus 4 and Galaxy S2 by using the spring tension.

AutoPad's capacity is 1A with the help of special plating on the PCB. It can cover most of big volume of battery.

For example, if Galaxy S3 case connected into USB port of the phone, it can supply 900mAh.

And AutoPad's centering position is the same distance as Powermat receiver case, which means it is perect to match with ours and Powermat.

For CarPad, Powermat should be upside-down.

Be happy day!

Moon
[Nexus 4 Accessories] delrazor:
----------------------

Thanks for feed back report.

I think it is quite good sign that we are going to succeed in launching of Nexus 4 with Owl AutoPad or CarPad

Already we fixed this problem when we tested the Qi module of Galaxy Note 2.

I will send this AutoPad to you soonest possible.

This is more fast charging and low temperature and no error like turn to Green.

Best regards,

Moon

More good news from Moon.

Seems they knew of these issues and have already stamped them out.
[Nexus 4 Accessories] the co0kie:
AWESOME!

Id like to see a test with GPS at about 2/3 brightness (or whatever is sufficaent to see the screen in the daylight) if at all possible, Just want to know if it can charge or atleast hold
[Nexus 4 Accessories] delrazor:
Will do next time I head out this morning.

I've been driving with just Spotify and it can definitely handle that just fine.

On a side note, does anyone know of any apps that will show mA input from a charger? I found a few that show my mA usage, but not charge input.

While playing NFS:most wanted, it was using upward of 1A most of the time, about 1200ma at max, so I can understand that this charger probably couldn't keep a charge while doing that.
[Nexus 4 Accessories] peachpuff:
Battery monitor widget will show you that, i get around 885mA when charging from the ac plug.
[Nexus 4 Accessories] kpjimmy:
Maybe use CPU spy pr battery spy?

From what I understand, Qi charging will stop charging at some point above 95% and will not charge again until it drops below 95%. Is this what you are running into?
[Nexus 4 Accessories] delrazor:
No, I made sure I was in the 60's before testing.
[Nexus 4 Accessories] TechSavvy2:
I'm pretty sure its supposed to stop at a full 100%, and then start charging again once it dips below 95%. Thats how several other qi enabled devices run.
[Nexus 4 Accessories] delrazor:
OK, so I went out for about 40 minutes. Turned on navigation to some place states away, so I'd never reach my destination, and just left the screen on at 50% brightness. No other programs were in my previous list, and WiFi and Bluetooth were off, GPS was obviously on.

For half the trip it remained in charging mode, and the battery percentage never dropped. It stayed right at 61% the whole time.

Then the charger went green. I realized I had heat from my car vent blowing right on it, so I turned the AC on and had that blow on it. Charging resumed after sliding it out and back into the dock. Finished the trip with no other issues.

The percentage never dropped from 61% the entire time.

I realize this may show that heat is a factor in the charger stopping. As Moon stated previously, they have figured that issue out with the AutoPaf product, and fixed the temperature issue. The product I have is called the CarPad. I'm not sure if they've fixed this problem in the CarPad product, but I'll bring it to his attention.

Hope this helps.

Edit: here's a screenshot of my battery usage just after returning home. I think in was wrong about the halfway mark of my trip. Looks like it was more around 2/3rds of my trip before the charger went green.

[Nexus 4 Accessories] lafrad:
There is an app called "Battery Monitor Widget" on the market... you drop the 1x1 widget onto a homescreen, and it logs the Volts, mA, mW, Temp, etc etc and spits them out in graph form after you launch the app. It should let you see whats going on a bit better here while you are testing these docks...

Oh, I'd like to be on the list when one is found :)
[Nexus 4 Accessories] delrazor:
I've got that app, and it does seem to do a decent job.. Only problem being, as far as I can tell, the shortest increment of logging is once every 10 minutes. Id love to have a much faster log, even every half minute or few seconds would be great.

I normally dont have a whole lot of time to test out the charger, and when i do, I'd like to make the most of my time by trying different things.

If it doesnt even record the current mA charge until I've waited 10 minutes then something is definitely wrong.

I think I may be overlooking something.
[HTC Amaze 4G] bry2872:
I have an s-off,unlocked bootloader and custom rom htc amaze. My phone keeps rebooting randomly. It even rebooted when it was s-on and locked bootloader with the stock rom. I don't know what to do I got a new battery as well,Anker battery I bought off amazon. Even with the new battery it still reboot randomly. Is it the phone or the battery? the battery that came with the phone I knew it was messed up because it kept dying really quick and it took forever to charge. Even tho I got the phone new at T-Mobile. I don't have the same contract anymore I got a new contract so I don't have insurance on the phone.
[HTC Amaze 4G] wolf_7669:
When I start getting random reboots, the first thing I try is recalibrating the battery. The battery stats can get out of whack when flashing a new rom or installing a new battery which will cause random rebooting.

To reset the battery stats:

1) Charge your phone to 100%

2) Reboot into Recovery and select clear battery stats (or use a app like BatteryCalibration to reset stats without using Recovery mode)

3) Reboot into Rom (if recovery method used)

4) Use phone and do not charge until it dies, then fully recharge. Suggest repeating step 4 two or three times.
[HTC Amaze 4G] bry2872:
I've done that already. But it still reboots
[HTC Amaze 4G] wolf_7669:
Are you using 4ext recovery? If not switch to it, it works better than the other recoveries on HTC phones.

Have you tried reflashing the stock ICS RUU? When I first upgraded to ICS and flashed a custom rom, my phone was doing weird things and was unstable. Was still acting the same when I tried a different custom rom. So I decided to start fresh and wiped everything then reflashed the stock rom. After that, I wiped everything again and flashed a custom rom again. Everything has been fine since (knock on wood).

If that's not it, I'm out of ideas and hope someone more knowledgeable will chime in.

PS. Don't do a restore to the stock rom if you made a backup. Actually flash the stock rom.
[HTC Amaze 4G] Double0EK:
Change your battery. It's been mentioned on here more than a dozen times.
