Its more like the last one as it has LEDs in it. Just figured it might be good to have the link as its a inexpensive option as long as color doesn't matter

---------- Post added at 02:12 AM ---------- Previous post was at 01:56 AM ----------

Just trying to help and contribute. Thanks for replying and pointing me in the direction of some nice wireless chargers.

I'll make a new subsection for Qi chargers/Sellers that other XDA members have bought from and used. If you can give me a non mobile version of the page I will add it.

Anyone else who has bought off of ebay/aliexpress/etc and have had positive performance/experience, please provide links for me and I will add them as well.

This should work, sorry about the mobile link

[Nexus 5 Accessories] thematrixanomaly:
Thanks!

That was a really in depth review, thanks for that. Been considering going wireless with one of those cheaper ones and I might just settle for the tilted one. :good:
[Nexus 5 Accessories] keepermike:
So I just wanted to let everyone know after my first night with this charger it worked great, has a very forgiving area of recognition. I would just suggest if you do get one pop it open and sharpie over the LEDs as they are quite bright. Its only held together with clips no glue so it came apart very easy.
[Nexus 5 Accessories] ynrozturk:
Not your fault at all. You took a good deal of your time in reviewing those chargers. No one could have known that the Q8 would be changed up like that.

And besides, it was only like 10 bucks.
[Nexus 5 Accessories] fooznugget:
So I had 3 of the round puck chargers already before I read this thread. I really like the small size of the puck charger and personally, I really prefer the look over the rectangular ones. The only real flaw with them in my opinion is that it beeps obnoxiously loud when you put the phone on the charger. I've woken up my wife by placing the phone on the charger while she was already asleep. I wanted to use it at work also, but it's an office environment, and I feel like it would get on people's nerves. After I read the thread, I also bought a Q8, only to end up with the red LED version that does not work well at all.

Earlier in the thread, I had tried to figure out a way to take the puck charger apart, but mine did not have screws under the rubber like mmmmBACON's version. Anyway, I just got so frustrated with the Q8 charger, that I set out to get the puck charger open to remove the speaker. I took some pictures and thought I would post some pictures in case someone else is in a similar situation as myself, and really would prefer to get a smaller charger, but doesn't want to get something that beeps.

The only tools I needed was a small flat head screwdriver and flat eyeglass screwdriver.

First I wedged the small screwdriver under the lip near the miniusb port.

If you stick the eyeglass screwdriver under the plastic a small distance away and pry up, it will release one of the tabs that is holding the charger together.

Do the same thing on the other side.

Next, I stuck the screwdriver into the space that opened up above the miniusb port and twisted the screwdriver to pry the top and bottom apart. You have to be a bit careful here because the miniusb port will move up with the top piece when you are trying to pry them apart. You could stick the screwdriver into the miniusb port and potentially damage it if you are not careful.

here's what it looks like once taken apart. You can see the 6 tabs that were holding these together.

The speaker is labeled J1 on the PCB and it has a + sign with a circle around it. If you look at the corner that has the + sign, there is a small hole towards the bottom of that corner. I stuck the eyeglass screwdriver in there to pop off the top plastic cover.

Once you get the cover off, there is a small metal disc that you must also pry off.

Here is the speaker with the disc removed. At this point, I just put the plastic cover back on the speaker, and then put the two pieces of the charger back together.

Add Powermat compatibility to Nexus 5?

Sorry - this is pretty off topic, but if you're reading this thread you might have a view...

I read something on the Verge (via Guardian boot up) about Starbucks introducing Powermat charging stations in their international chain of public toilets (I noticed recently that some have introduced a hot-drinks concession in the seating area outside the bathroom)

I thought Powermat was dead and buried but it seems not - I read a claim that Apple might adopt Powermat with their future devices

I've read about mods to other handsets to make them Powermat compatible and wondered if it might be worth trying to stick a powermat coil in the back of an N5 rubber case - whether having a Qi coil (internally) and a Powermat coil (externally) would allow it to work with both standards (only matters if Powermat is ever adopted anywhere - this Verge article is the only sign I've seen in the last few years that it might be). If it's only introduced at Starbucks there would be no point, but if it takes off it might be handy to be able to use both

I was reading about Powermat coils and it looks like they are a bit fatter than Qi receiver coils (pretty flat as I understand it). Does anyone know how thick they are? Would one bulge too much for a rubber case? Or if having a Powermat coil in the way of a Qi coil would affect the Qi charging? My recall of A-level physics tells me it shouldn't - if it doesn't resonate it shouldn't drain power, I think

I'm tempted to buy something like this and start chopping

Anyone have any thoughts?

The link in the OP no longer worked so I just searched "Qi Wireless Charger for Samsung Galaxy S3" and found some listings.

http://www.ebay.com/itm/Qi-Wireless...S_Cell_Phone_PDA_Chargers&hash=item1e7fb8f320

even cheaper

[Nexus 5 Accessories] dspcap:
Are there any sellers out of the US that have a decent / good wireless charger? Going through all the links, I see they are all overseas. I already tried purchasing one overseas and I never received it.

I've been following this thread for a while, I did try to get the initial Q8, but that's the one that I never received.

What about a car dock?

Wow, great review! I ordered the tilt Qi, plus the blackberry chargers (double pack), and am waiting for the back of my Samsung S5 to arrive (yes, I have a Samsung, not a Nexus, and yes, you have to replace the back of the phone to get wireless charging). You saved me a bunch of money!

So, does anyone have an equally useful tip for a car dock with wireless charging built in? Hopefully universal enough to accomodate the Nexus (for most people here) and the Galaxy S5 (for me:D), and in a similar price range?

Thanks!
[Nexus 5 Accessories] ckbcowboy:
I hope this isn't off-topic!

Does anyone know if any of these chargers work with the Galaxy S5 Qi charging back? The reason I ask is that, not knowing specifics of the Qi standard, I went ahead and ordered a few of the "Qi Charger - Large Rectangle w/LEDs" charger mentioned in the OP, but while they all work with my friend's Nexus 5, none of them work with my Galaxy S5.

I actually posted this as a standalone question in the Galaxy S5 Q&A forum, but I figured I'd mention it here in case anyone knew the answer.

Thanks.
[Nexus 5 Accessories] tkurkowski:
I suspect they have to have definite limits. The induction rate goes down as the separation distance increases, of course, so as you increase the separation by some 50% the power needed to charge at the same rate would have to go up. But if they deliver that much power, folks using it at the "normal" 5mm or so distance would probably have overheating problems.

Ted
[Nexus 5 Accessories] teamshao:
As you said, the wrong forum. But I'll just answer your question: the S5 doesn't have native wireless charging. You have the buy a special battery cover from Samsung to do it. Google it.
[Nexus 5 Accessories] tkurkowski:
And after you get the wireless cover, I wouldn't worry too much about chargers working with it. I have 3 different chargers (including the Samsung OEM one), they all work fine, and only the Samsung was more than $20.00.

repost first link to qi charger without LED

Thanks for the great write up. I noticed the link to Ebay for the first charger without LED is no longer working. Can someone repost? Or a link to amazon? I am looking to get this one. I hate the led lights. Thanks again.
[Nexus 5 Accessories] ckbcowboy:
I'm aware of this, sorry for not posting it in this thread (I mentioned it in the other thread). I've tried *two* different official Samsung Qi charging backs for my Galaxy S5 and neither of them works with the aforementioned charging pad.

So, what I'm saying is that with two separate Galaxy S5 + Qi charging backs, three separate Qi chargers didn't work. But they worked fine with a Nexus 5.
[Nexus 5 Accessories] vin4yak:
Aren't there any cheap wireless chargers available which have 1.8A output as the Official Nexus Wireless Charger? Has anybody used the official one and seen what's the average current which is achieved?? :roll-eyes:
[Nexus 5 Accessories] mmmmBACON:
You're mixing up input with output. The official Nexus wireless charger is no different than all the others.

1.8A input

1.0A output

All of the Qi chargers I listed in the OP (and almost all Qi chargers out there really) have 1A output. The stated input is what tends to vary slightly, from 1.5A - 2.0A input.
[Nexus 5 Accessories] vin4yak:
Oh Alright, thanks for the clarification. I read that it outputs 1.8A in some articles like this one: http://www.androidpolice.com/2013/11/26/nexus-wireless-charger-2013-review-you-get-what-you-pay-for/ So, I got confused regarding the same.
[Nexus 5 Accessories] mmmmBACON:
Yeah, that page has some of their information wrong. The power brick does have 1.8A output, but that is the AC Adapter powering the Qi pad, not the pad itself. The Qi pad requires 1.8A input, but has 1.0A output.

It is the same thing for example, as using the 1.8A Blackberry Folding Blade chargers, to power any of the 1.0A output Qi chargers in the OP.
[Nexus 5 Accessories] :
I found on aliexpress offer with Q8 charger with pictures with blue led. I asked about version and this is his answer : "With the same picture. Blue LED". I can`t post link but this is tittle: "HOT SALE ! Black Q8 Qi Standard Wireless Charger Pad for Nokia Lumia 920 Nexus 4/5 Samsung Galaxy S3/S4/N7100"
[MENTION=3746653]mmmmBACON[/MENTION] how did you know "They no longer carry the version"? Is it confirmed? Maybe this is fake or he has some old supply with blue led version?

btw which of chargers is the best in your opinion?
[Nexus 5 Accessories] pchoppe79:
many thanks

Just wanted to say thankyou for such a detailed review and B for saving me a considerable amount of money :)
[Nexus 5 Accessories] TheJuicer:
Thank you!

You are a rock star! Ordering tonight. Many thanks again!
[Nexus 5 Accessories] phreich:
Just a word of warning about the rectangular one with the two non-bright LEDs beneith the plastic -- I went to bed last night and discovered that the green "connection" light was on, even though nothing was on top of it. I picked it up to check it out, and discovered that it was so hot that the plastic case had softened. Needless to say, I can't trust it anymore, and haven't used it since. The company I bought it from on Ebay offerred a one year warranty on it, but I asked them to send me one of the round ones with the rubber circle as I can't trust this model anymore.

SO BEWARE -- it may be a design flaw in this model, and it could start a fire.

[MENTION=3746653]mmmmBACON[/MENTION]

Forgive me for being inquisitive. I had contacted google support as well regarding the output of the Nexus Wireless Charger sold on the playstore and they assured me that the Nexus Wireless Charger will charge the device at 1.8A which faster than the stock LG charger (1.2A).

However, in your earlier post you told me that the output of the charger powering the pad is 1.8A but the pad itself only outputs 1A which means the phone will be charged at 1A even if I get the Nexus Wireless Charger. I hope I understood you clearly on this? :confused:

I don't mind paying extra for the official nexus wireless charger as long as it charges my device at 1.8A (which the google support team says). I want to be damn sure about whether the information they've provided is true or not before I buy anything. If it's not, there's no point in spending so much on the official nexus charger.

Thanks a lot for your time! :)

Here's the SS of the mail I received:
[Nexus 5 Accessories] mmmmBACON:
Yes, your phone will be charged at 1.0A (a range of 700mA - 800mA in real world performance when you take ~75% wireless charging efficiency into consideration).

Don't listen to that rep. They are just quoting the wired charger you can buy on the Play Store. They sell both the Wired Charger + Qi Pad, and the Wired Charger by itself.

There are ZERO Wireless Qi chargers out on the market today that output more than 1.0A from the pad.

Again the wired AC Adapter is 1.8A which powers the Qi pad, the Pad is 1.0A output. The Google rep in your mail did not specify "Wireless Charger output" in their reply to you, simply Nexus charger, which is the 9W 1.8A AC Adapter they sell. Look at the Google Play store, you will see it there.

If you want to speak with a Google rep again to question it further that's fine, but I am 100% certain on this.
[Nexus 5 Accessories] vin4yak:
Thanks for clearing the air again! Going to buy the last Rectangle Qi charger that you've recommended in earlier posts! :)

I have a 1.8A Sony Charger which I'm using right now. That will be sufficient to power the Qi pad, right?

Works fine with my Galaxy S5

I have no explanation for your problem but something is wrong. I received the charging back from my S5 yesterday and it works fine on the tilted charger. It took me a minute or two to find the best spot (turns out right in the middle of the phone -- duh!) but now it charges the battery perfectly.

Don't know what advice to give but it may be helpful for you to know that there is nothing wrong with the system, it is either your (multiple) chargers or (multipe) charging backs.

JRK-1688 Qi Wireless Charger with 6000mAH build in Power Bank

yes, this is the 1 i'm getting too, but FYI this is the genuine re-brand from JRK-1688 china make charger, tested and below the result and I love it:

1. 6000mAH LiPo battery within (yeah I've opened my charger since day 1 of purchase)

2. You only able to use both wireless charging and the 5V usb port at the same time when you're on the Battery mode (you will notice your 5V usb be cut off once you plug in power adapter)

3. It take 6 hours to fully charge up the internal battery (using samsung 2A charger, yeah it's slower and u're advice to charge full the internal battery before use as this charger will act funny when its internal battery not full)

4. NO MORE continuous beep when you wireless charge your phone overnight (good for sleep)

5. The wireless charge rate can hit 1000mAH (tested with my Lumia 1520, 84% to 100% in less than 30mins)

6. The charger will maintain phone at 100% charged, yes and this is what I love the most compare with those total shutdown charger which once phone full and shutdown never turn back on again when the phone battery start dropping and you get none full charged battery in the morning.

So for the TS the 700mAH~800mAH charge rate from your experiment seem cause by the device you're using (LG Nexus) and not because of the wireless charger limitation, and I believe those charge rate stated within the charger really are their limit (where if it stated 1000mAH then it really can get there), I'm not sure you will re-run the experiment or not, but I can tell you my Lumia 1520 able to get 16% (from its 3400mAH battery) within 30mins of charging time that for sure... hope this information will help anyone who interested out there... :highfive:

nexus 7 with the rectangle with LEDs

I don't know if it is just because I'm am using a nexus 7 but I did part of the test with the rectangle with LEDs and I got 4%per 15 minutes. Is my qi charger messed up or is it because I'm using a nexus 7??

Needed confirmation that this is the same charger as the 4th one in the op. http://www.ebay.com/itm/Qi-Wireless...l_Phone_PDA_Chargers&var=&hash=item4864425785

I'm moving to Vietnam in August and wanted to pick up a second receiver. So I want to buy from a US seller so I get it in time before I leave. I'm using the tilted one now, but want to use that one in the office and use the lay flat one on the nightstand.

Btw, I'm a sucker. So I'll pay extra for a charger in a pretty color. Silly, but that's what motivates me sometimes!

[Nexus 5 Accessories] bblzd:
Welcome to the forums. I don't think 40C is the maximum operating temperature for the battery, maybe just when it starts to exhibit thermal throttling. The reason I say this is because even the outside of the phone can get warmer than 40C at times, surely the inside gets much warmer then that.

- Anandtech

It's known that all wireless charging will increase temps compared to wired charging. Roughly 25% of the energy provided doesn't make it into the phone, instead becoming waste heat. The official Google charger is no different.

I got this charger. I believe it is exactly the same as the round puck inside since the instruction manual has a picture of them both. Everything said about the puck in the OP applies to this as far as I can tell. I have to be a bit careful with placing the phone on the mat, but otherwise it looks and performs well.

Hello

Finally i got my wireless charger yesterday but i have a question.

How does wirless charging impact on the battrey, i know that we have Li-ion, is it possible to have a sort of memory effect?

By placing the device on the charger and taking him back in the hand form time to time we are stopping the charge.

Can this bring any issues to our batteries?

Thank you in advance for your answers.

Anyone to My question on post #370?
[Nexus 5 Accessories] keepermike:
Li-ion and li-po batteries don't hold a memory regardless of it being plugged in via USB cable or wireless charging. The battery doesn't know how its being charged, that's what the mother board and charging circuit are for.
[Nexus 5 Accessories] B.Ken:
You are correct. I received the Nexus charger...and it did the same thing - the battery temp climbed to over 104% F - and then I took it off the Nexus charger.

What was interesting...is that I could not charge my phone with the case on with the Nexus charger..but I could with the inexpensive "puck" charger!

BTW - the case is a Ballistic SG MAXX for the Nexus 5

Tried the puck charger again (BTW - cost me about $8)

Time Batt-Temp %-charged

18:49 90.9F 17% (on puck charger)

19:29 104.5F 40%

19:30 105.6F 40% (off puck charger)

I only have 3 recorded data points with the Nexus charger (remember - I had to remove the hard case to use the Nexus charger...but left the softer "gel" case on the phone)

Time Batt-Temp %-charged

18:50 89.4F 24% (started on Nexus charger)

19:29 103.5F 47%

19:43 104.7F 56% (took off Nexus charger)

So...deciding not to have to worry about ruining my battery (high temps make it degrade faster, from what I read) - I returned the Nexus charger back to google.

FYI - in case you were wondering...I also tried the Nexus charger without the case - just the plain phone on the charger and had the same high battery temp results - I just didn't record them.
