Re: Qi Wireless Charging Car Mount

These screenshots are from my Panasonic Qi.

It looks like the phone/charger starts to reduce the current from 90%and above. My guest is that the battery has circuitry responsible for profiling charging cycle based on temperature and charge level.

Moon mentioned that he has never seen such a behaviour with any other handsets.

I will run some temp tests as advised by delrazor and post the results soon.

New video by Owl: [YOUTUBE]ufA_1SBTYaY[/YOUTUBE]

Anyone know why there is a red light on the charger?
[Nexus 4 Accessories] delrazor:
The red light means it's charging... it turns green when it completes charge. it's also a button you can press to stop charging entirely and just use the CarPad as a holder if you are good on your charge.

The red light isn't very bright or annoying by any means.. you can hardly see it in daylight.

What he didn't show in the video, is that if you keep the phone off the pad for a few moments, it turns green again.. then once charging starts after placing the phone back on the pad, it turns red again.

I'm going to try to make some vids with mine shortly, and be as detailed as possible when I can. Moon has sent over 1 more test unit as well. This one claims to be a little less aggressive on the charging side, but in the same regard, will not heat up as much because of that.

Honestly, if I can get something that just maintains my charge while using GPS and Music, I'd be fine.. i'm not overly concerned about boosting up my charge percentage, more than I am making sure that the phone doesn't crap out on a drive when I don't know where I'm going.

Current tests are showing me that I get about 200-300+ mA while running music and GPS at lowest screen brightness, but it gets a bit too hot. If that could be tweaked down a bit, as this new test unit is promising, to just even out the charge around 50+mA or even zeroed out, in order to just maintain a charge, that would be fantastic, as it wouldn't get nearly as hot in usage, and my phone would be happily staying alive and not draining.

Will have more tests soon.
[Nexus 4 Accessories] facetubespam:
Thanks!

Are the grips on the owlpad rubberized or fashioned in some way that does not hurt the phone from the constant taking out and putting back in?
[Nexus 4 Accessories] delrazor:
There's a slight texture to the side prongs, but they are just plastic. I have been sliding it in and out using the LG bumper, TPU cases, and the bare phone, and no signs of problems scuffing or anything.

I mainly slide the phone in from the top though. The bare phone is a perfect fit for this, just barely needing any pressure to push it in from the top.
[Nexus 4 Accessories] themadeira:
delrazor,

How many mA do you get with this pad you currently own when not using GPS nor music? Around 600-700 mA?

Any noticeable difference with case installed/uninstalled?
[Nexus 4 Accessories] delrazor:
Averages about 650-670mA with nothing running, screen off. I'd expect this new one would tone that down to about 350-400mA? Not sure, but iol test soon.

As i recall, isnt there a cut off to how high the mA the phone will receive? Even from a wall charger? Maybe this one is over that threshold and that's why it's getting warmer?

More testing soon!
[Nexus 4 Accessories] themadeira:
650-670mA is great for a wireless charger.

People have mentioned this cut off. I wouldn't risk a number though. I get 780-800mA from the stock wall charger (nothing running, screen off).
[Nexus 4 Accessories] delrazor:
Not if it gets too hot to be safe for the phone. I'm glad to see Moon would rather have a safe temperature and maybe not full on charging, instead of just throwing as much power at it as they want and not caring about the temperature.
[Nexus 4 Accessories] themadeira:
True. I agree with you.

BTW, let me complete my previous post. My phone has never reached more than 35-36C while being charged with the stock charger. So I cannot say about the decrease in mA due to high temps. I will run a few tests and post what I get.
[Nexus 4 Accessories] Duncank:
Does the phone only get so hot the charger turns off while it's being used actively (GPS+Music)? I'm asking because I've got a wireless charger at home, just a normal one, not a car-charger, and I can't feel any significant temperature differences while charging. I'm not using the phone at that time though...
[Nexus 4 Accessories] bedoig:
I think it would also be useful if we could create a baseline by recording temperatures using a micro-USB car charger under the same circumstances as the Qi-based tests. These phones tend to run pretty warm with just the screen on when under moderate use. Any kind of charging is going to exacerbate that, so I'd be interested in the difference between wired and wireless temperatures in identical scenarios.
[Nexus 4 Accessories] Ignite023:
Can orders still be placed? If so, I would like to purchase one.
[Nexus 4 Accessories] neotekz:
i hope the new one isnt downgraded to 400mA, that's not even enough to keep the battery at the same level with the screen on.

The phone does charge at different rate depending on the voltage left in the battery. You usually only need high mA at the beginning and end of the charge cycle.
[Nexus 4 Accessories] delrazor:
I'll have screenshots later this morning, but I wanted to do a quick update to let everyone know how the 3rd test unit is doing.

So far, from all my tests, it's the one we've been waiting for. I drove around for about 20 minutes yesterday, with GPS and music streaming, and screen at lowest brightness, and my phone never dipped into negative mA, often hovering around +100-200mA at each reading.

The great part is that the temperature doesn't go nearly as high as it previously did. They've really worked out the kinks with this latest revision, and I think it's really showing how dedicated they are to making a good quality product that isn't just thrown together.

The heat on mine, from what I recall was around 27 degrees Celsius when I started, and after 20 minutes of continuous charge, screen on, GPS and streaming music, it was stalling around 38 degrees C. the second unit I had received would easily have kept moving upward into the 40s.

As I said, I'll try to have screenshots later today for hard-evidence.

Moon has also updated his page with a LOT more test results and photos.

http://owlpad.net/carpad-for-nexus-4/

I think this is the unit I'll be doing a review video with, to demonstrate the product and show how it works, etc. I'll try to have a video review together by the end of the weekend. Gotta shoot it on another phone while using my N4 as a model. Also, need to clean out my car! lol.
[Nexus 4 Accessories] themadeira:
THAT is great news!

Just one reminder. If possible, please let us know how it performs with screen off, nothing running.

Thank you for all your tests so far.
[Nexus 4 Accessories] delrazor:
Alright, here we go!

I've just gotten back from my morning travels and have a couple of screenshots for you all.

These are using the latest unit Moon sent me.

This first one, as requested, is just the phone sitting on the charger, no Bluetooth, no GPS, no Music. Mobile data ON. Screen OFF.

The test was from 8:09am to 8:15am

http://i.imgur.com/hB01A1e.png

The second test was with GPS on and navigation app running, streaming music via Spotify, using BlueTooth to my car head unit, screen ON at lowest brightness.

The test was from 8:26am to 8:34am

http://i.imgur.com/kydLRAU.png

As you can see, with the phone just idling, there's a decent charge provided to the phone.

With everything running, I'm still getting a charge to the phone and the mA amount recorded never dips below zero.

The temps with everything running were nice and low, and unlike the second test unit I received, they did not rise quickly. Previously, within about 8-10 minutes, with everything running, my phone would see a rise in temperature of almost 10 degrees, and it would continue until it reached that 40-41 degree threshold where it would stop charging.

I was using a very thin, cheap, TPU case during this test. Maybe 1-1.5mm thick. I wouldn't expect much different results with a bare back on the charger.

I'm super happy this is turning out to be the charger we were all hoping for.

Let me know if any of you have any other questions.
[Nexus 4 Accessories] facetubespam:
Thanks for your reports and tests.

Can you check to see if it is possible to use it without the suction mount? As in, replace a suction mount for another kind of mount from a 3rd party?
[Nexus 4 Accessories] delrazor:
I know Arkon's stuff is interchangeable with it. The back of the charging pad is attached via a nut and bolt to the holder arms. The back of that has a socket joint hole which can be used with any 17mm ball on a mount.

If you search for "Arkon swivel" on amazon you'll find a ton of different applications that will work for the carpad.

I personally bought the Arkon MG178 because I would rather have a dash mount setup and my dash is curved. The arm on that one will interchange with the arm on the CarPad mount.

I'll be doing a breakdown of the CarPad in either video or photo form to show everyone soon.
[Nexus 4 Accessories] slam80:
I'd like to order one as well.
[Nexus 4 Accessories] wind003kxda:
Would do a test with a bare phone

Thanks for your test, this is much helpful. Would you do one more test to see the performance of a bare phone charging? Appreciate!
[Nexus 4 Accessories] idigg:
Are we able to order these? Is the product in final production with the bugs worked out? Is someone from the US buying a bunch of these and giving XDA members a discount? I can't read all the pages :D
[Nexus 4 Accessories] neotekz:
That's great news. Those charging temps and current output looks good.

delrazor will you be selling these too?
[Nexus 4 Accessories] delrazor:
Sorry, I won't. Don't have the financial base to buy a bunch and possibly not make the money back. I will be approaching some larger product manufacturers on behalf of Mr. Moon.

As far as I know, Narcopalypse will be purchasing and selling these to most members here that have expressed interest. Moon said he would not be allowing SOLE distributor/reseller rights in the USA, so anyone could literally contact him and purchase in bulk and sell them, I.e. car phone warehouse, Best Buy, etc.

I may look into helping Moon setup and maintain a small stock here in the US, which could be sold via Amazon or similar, and when stock runs low he could ship more over, sort of like a middle-man to hold the stock local for him.

Will do, both with no apps running and screen off and also under load.
[Nexus 4 Accessories] diablonyc2:
Thanks...I just ordered the Arkon MG178 ---- I received a dock from him this week and that was the only thing I didn't like. I have not had a chance to test it as the car only goes out on weekends

Car Dock with integrated wireless charging for DNA

Hi, does this work with HTC DNA? I saw on the site it was not listed.

Are these shipping now?
[Nexus 4 Accessories] idigg:
Me too, just ordered one straight from owl/moon.
[Nexus 4 Accessories] facetubespam:
The HTC DNA uses Qi technology so it should work. I know the DNA works with the Nokia chargers and the LG and Energizer ones, so it should work with Owl's products as well.

If you want clarification, just email Owl and ask them.
[Nexus 4 Accessories] dangerman14:
Latest update from Moon seems good!, sounds like he's fixed the high temp cut-off problem...

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

Please see below test results for latest version of Owl CarPad/G.

We did only focus on GPS. But we have to care also for streaming music for a benefit of Nexus 4 users.

In terms of iPhone 4/4S, Galaxy S2, normal CarPad is okay for both using GPS and streaming music together.

http://www.youtube.com/watch?feature=player_detailpage&v=33NE1qegK-0

Driving test :

Navigating using GPS and streaming music to Bluetooth. The charge did go down about 4% during 50 minutes driving test.

Maximum temp was 38.9 degree.

High temperature test :

Intensionally, closer the nexus 4 at the vent of hot air (actual hot air temp was 60 degree)

Nexus 4 internal temp jump to 46 degree but still on charging.

Even using at hot country, it would be no problem for charging generally.

Regarding this update,

We would like to send new replacement for you who already have received.

If you paid already, would you please wait for a weeks until we are ready to ship it to you?

If you have any comments and suggestions, please leave a message.

Thanks

Moon
[Nexus 4 Accessories] neotekz:
i dont think so, didnt get any shipping notification. i think moon said on the email that it might take a few weeks.

Re: Qi Wireless Charging Car Mount

How/where are you ordering them? Thanks.

Edit: never mind, I found it. However, question.

Does this use a car adapter plug or does have to be hard wired into the car power system?
[Nexus 4 Accessories] diablonyc2:
It uses a cigarette Lighter adapter (which is included)...I am sure more adveturous people can hard wire it.
[Nexus 4 Accessories] simics:
thefundi who

I ordered an carpad for my N4 and got pretty bad results at charging.

200+ma charing speed with phone idle/screen off. If i start streaming / GPS, it goes into negative mA instantly.

awaiting the new carpad/G version from Moon to see if its better.

i46.tinypic.com/34hf7zs.jpg

Phone idle and screen off from 4:15 to 4:24.

Tunein Radio streaming from 4:25 onwards.

My N4 is encased in a TPU cover.

The cigarette adapter get very hot during charging and there seems to be something loose and rattling inside.

Moon will be sending me a replacement adaptor to see if that could be the culprit.

Re: Qi Wireless Charging Car Mount

How are you contacting moon. I want to purchase the better one to start with but i have never gotten a reply from him,

Thanks.
[Nexus 4 Accessories] delrazor:
You can contact Moon at moon@owlcharger.com. He's in South Korea, so they're time is off from us if you are in the West.

Normally I'll email him one day and not hear back until late the next day or sometimes a following day.

Seems like he's handling a lot of orders right now, so I wouldn't doubt if his response time may be down a little bit.
[Nexus 4 Accessories] delrazor:
I'm sorry to see that is your first experience with the charger.

When did you order it? He's got that new batch of ones that are updated that will be going out on the second week of February or something like that.

When they first went up on the website for purchase, I distinctly remember him saying that it was still a test version, and it was for early use/testing.

I'm pretty sure you'll be happy when he sends the /G version (not sure why it's called that, although I can gather it might have to do with gold plating on the circuit board, which he had mentioned trying at one point.

Arkon MG178 - an option to dash mount the Owl CarPad

Hey All,

Things have been super busy for me, sorry for being quiet lately.

I just received my Arkon MG178 and wanted to let you know that it works great for the purposes I needed it for. I like to dash mount my CarPad, and the provided sucker mount just doesn't work well for me, even with the provided 3m disc to place the sucker onto.

The arm that comes with the MG178 has the same sized ball as the CarPad's setup (17mm), and the screw ring that came with our CarPad DOES work with it, although I found the tightened down connection to be a little bit looser than the CarPad's.

I went ahead and took the arm off of my CarPad provided mount, and mounted it onto the MG178 and it fits really nice. No tools needed, just swap and go. The CarPad stays nice and tight like I need it, and the base is surprisingly secure. I attached it to my computer desk, which has an embossed wood-grain. the normal sucker that came with the CarPad would never even hold a suction against it, but this thing sticks to it like glue. It's not very noticeably sticky to the touch, but whatever the material is fills in gaps on the sucker so it still has great suction on the surface. I could pull my phone straight up and out of the holder, with a case on, and there was no budging or pulling of the mount. Currently in my car with the sucker mount and 3g mounting disc, there's a noticeable give when I try to pull my phone out of the charger, and I feel like I need to hold the base while I pull the phone up and out.

Just figured I'd let you all know if you needed a dash mount solution.

This is the exact mounting hardware that comes with the CarPad : http://amzn.com/B000U0S304

Here's some of the other solutions that should work with the CarPad Ball-Joint Back.

Sticky Dash Suction Mount This is the one I bought : http://amzn.com/B0077B9K2E

The above is the same as this, but for some reason, that one is cheaper with the holder attachment than this one is solo : http://amzn.com/B005V1L7W8

Vent Clip mount : http://amzn.com/B0015A6YN6

Cig Lighter port stalk : http://amzn.com/B000BP8GQO

For you Brodit / ProClip users out there, i BELIEVE this is what you would need : http://amzn.com/B002ACP2FY

You can basically look up Arkon 17mm ball on Amazon and have a lot of options to play with for the back of the CarPad. It's nice they adapted it to a standard ball mount so we can use these other options if needed.
[Nexus 4 Accessories] YasooKhuul:
I just ordered one CarPad G via their website without car mounting holder. I already bought one Brodit ProClip and a Arkon Adapter Plate.

I paid for the CarPad without car holder 57$.

Moon said that thei ship the new CarPad G next week.

How long is the cigarette lighter power cable? My 120v/12w power port is in my center console on the bottom, totally forgot about that.
[Nexus 4 Accessories] delrazor:
The cable has a coiled section in the middle to allow for additional length. The whole cable measures 29 inches total. 9.5" from the cig jack, then 7.5" of coiled cable, then 12" of cable again to the coaxial power connector.

The coiled section can be pulled to around 36 inches, but that's a lot of tension. I'd say doubling it to about 15" is as far as I'd ever have it taught.

I drive a 2010 Mazda 3 and my cig jack is at the bottom of my dash in the center console area.(think near your right knee) and I have my CarPad mounted on the top of my dash near my gauge cluster.

Here are some photos to show its construction.

Seeing all the positive feedback on XDA, I ordered it 18 Jan, owlpad + carpad combo.

The carpad arrive the next week, but he missed packing the owlpad in the initial shipment.

We were in constant email contact throughout, but he didnt exactly say that there is anything wrong with my carpad.

Moon shipped out the missing owlpad + replacement ciggy adapter yesterday, so I will test to see if the rattling ciggy adapter the culprit.

Was the initial version that slow in charging? Frankly, I was quite disappointed.

Hopefully the /G will fix it.

Again, he didnt say /G fixes slow charging, merely fixed charging under high temp conditions.

Awesome job OP updating the original post !

THANK YOU for taking the time !
[Nexus 4 Accessories] delrazor:
No problem on the updates. It's something I would want as well if I came into this topic.

Plus, I'm trying to play this little meta game where I keep my thanks meter almost as high as my post count. ;)

On an additional note, I received my Diztronic matte black case yesterday and wanted to say that the case works well with the charger. Its a little tougher to get into the holder, only because it's a little more grippy than the other TPU case I had previously. It's no problem to slide in one side and then the other, but I had gotten used to sliding in the phone from the top with a little wiggle.
[Nexus 4 Accessories] idigg:
Thank you so much for the pics, this helps. I have a 2012 Mazda 3, and I'm bummed out where my cig jack is located. Do you think I could source a longer power cable or would moon have something? Here is a pic of my interior... The very middle of the pic is the center console, which is where my cig jack is located on the bottom. If I can only stretch the power cable provided to maybe 3 feet, I could only mount the CarPad below my vents :crying: Any ideas?
[Nexus 4 Accessories] delrazor:
Re: Qi Wireless Charging Car Mount

Here's a pic of my setup.

http://i.imgur.com/VQuPdU9.jpg

You should be just fine, unless your port is all the way back in the cup holder area. If it's in front of the shifter, there's plenty of length.

As you can see in mine, the coiled part and pre-coiled part aren't even being used and are stashed in the little cabinet area. That's 17 inches of cable that aren't even used to place it where I've got it. Only the 12 inches of cable after the coil area are even showing.

That being said, there may be other alternatives. You could possibly get an in-line voltage regulator and hardwire/splice the cables to your cig port line, or I've even seen a USB to 1.5mm coaxial power connector cable out there as well.

The only caveat is that Moon said they did some work on the cig port adapter itself by adding a regulator so the CarPad wouldn't get too hot and the adapter wouldn't either. So your results using another cable may vary.
[Nexus 4 Accessories] facetubespam:
How come you didn't just get a vent mount there?
[Nexus 4 Accessories] delrazor:
My experience with vent-mounts in the past has been that they are flimsy and pop off easily after a little bit of usage.

Plus, being that this charger can get warm on its own, I'd like to make sure my vent isn't blowing on it, especially in the winter months when I need the heat on in the car. This way I can still direct the vent elsewhere in the car without having hot air blowing over it.

Also, this is a little higher than a vent mount would probably allow, and it's farther out (I can pretty much touch the phone while keeping my hand on the steering wheel)
[Nexus 4 Accessories] idigg:
You rock, I have the same car but a 2012. I had NO IDEA there was a cig jack under that flip up compartment, I never go in there. I'm going to set mine up just like yours. I'll order that dash mount from Amazon. Thanks again.
[Nexus 4 Accessories] delrazor:
So you know, the dash mount works great once you can find the right spot on the dash to place it. The cup on the bottom is about the same size as area from the tip of the vent to the crease in the back where the displays are. Took me a while to find an area where the cup would stick. I resorted to just mashing it up and down constantly in the general area until it finally didn't pull up easily and I knew I made my connection where it needed to be.
