My guess is that the Data Pins are shorted in the cable. I am assuming it is similar to this thread about Charging cables.

http://xdaforums.com/showthread.php?t=1984838

Even though 4.2+ fixed the described problem in that thread the Qi Charger is not set up that way. I am wondering if the Qi chargers were made USB 3.1 it would fix many of the charging issues. USB 2 was not originally designed to be a sole power supply it was just shaped into one and as a result there are too many variances in cables out there. USB 3 went in with this in mind. USB 3.1 actually increases the min charging current.

Side note is you could that cable with an Apple charger and see if that changes anything.

Adding Additional information

I have two qi chargers and my nexus 5. Chargers are nokia dt900 and an Anker wireless charger.

I'm going to do my own test and let you know the results. Hopefully you can add them in after I'm done.

Any tips on which widget/app to use to monitor current, etc?

Edit: Wow, first post. Man I'm a lurker
[Nexus 5 Accessories] CCyanescens:
So it looks like the links for the Q8 (from the original post, as well as the one mid-thread) have different-looking products now. Sorry I can't post URLs (new user; well, new poster, anyway).

The original post's link has a thicker slab, but the product model number does say Q8.

The other link shows a slab with intermediate thickness, but which also has two USB ports for charging additional devices. This also says Q8.

I like the idea of having additional USB ports to charge a secondary device, my backup battery pack, or a BT headset, but I'm curious what the effect on charging current would be. i.e. Would the Qi charging coil charge at maximum current without any other devices attached, but drop its current as soon as USB cables are attached to charge additional devices? From my (limited) understanding, Qi charging is less efficient at lower currents, so it's a double-whammy for the device because it's charging at a lower current, but that lower current is also less efficient.
[Nexus 5 Accessories] lsquare:
OP,

Will any of these qi chargers keep my phone charged at 100%? Or some of them suffer from the problem where the charger shuts off after charging to 100% and my phone's battery starts being drained and start charging from 90%?

Im buying a Q5 , i have a question if you can help me...

I have a Nilkin Skin in my nexus 5 , is any problem with he charger Q5 or i need to remove the skin any time i need to charge the phone?
[Nexus 5 Accessories] goofball2k:
They will charge it to and keep it at 100%. The only reason the OP suggested removing it at 90% is that the chargers gave a faster charging rate up to 90% vs the last 10%.
[Nexus 5 Accessories] mmmmBACON:
Yes, the Nexus 5 will remain at 100% charge until you take it off.

You are fine, it will charge through most cases, a skin is no problem.

It was still charging through this! The Q5 allowed 9 more sheets of paper than this one.

What is difference Q8 with this version? Only 2 usb ports?

[MENTION=3746653]mmmmBACON[/MENTION] Do all of the devices you reviewed have speakers except for the first one?

Sent from my Nexus 7 2013
[Nexus 5 Accessories] mmmmBACON:
None of the chargers I reviewed had speaker. The puck (Q5) is known to have a speaker for a lot of people, mine didn't though :good:. For the Q5, it will probably depend on the seller and the stock at the time for whether or not there is a speaker present.

[Nexus 5 Accessories] blackdragon12:
I got the titled qi charger off eBay and it has been working well for the last 2 weeks.. However today my phone seems to slip off the charger after a couple minutes. I have been using a case since day one (tudia melody).

Does anyone know any way of fixing this? Maybe putting something else on the charger to fix the slip? If not, I was looking at the q8 charger. How good would this charger with the case? Has anyone tried it?

Thanks!

[Nexus 5 Accessories] amoc1001:
Great review.

Let me start by saying that I am sure that not all of these chargers will have this problem and I am not suggesting that all chargers of this type will behave like the one I purchased.

I wanted to show what happened to me when using the first charger mentioned in the review.

I placed my phone on the charger to charge overnight ( no case ) just bare nexus 5.

The phone started to charge and everything seemed fine, so I went to bed.

The next day when waking up and picking up my phone this is what I found.

As you can see circled in the pics, the charger started to melt!

No damage was done to my phone, but the charger got VERY hot.

Since this happened I have purchased a Nokia DT-910 charger.

Just wanted to share my experience. Once again I am NOT suggesting all these chargers are bad, just showing my experience with the one I purchased.
[Nexus 5 Accessories] ediking007:
Looking very dangerous! Just wondering if it's possible to activate kind or loud alarm or ring phone if battery temperature is > 45° Celsius? Just in case...

P. S. I found this solution :https://play.google.com/store/apps/details?id=src.schimi.temperatureguardfree
[Nexus 5 Accessories] mmmmBACON:
Wow, that's interesting. Lots of people have that exact charger under various brand names and generics and this is the first I've heard of this problem. I have 2 of them and they work perfectly. Yours is the first I've seen anywhere online about the charger overheating like that.

The only other thing sort of similar was the Tylt Vu, but that wasn't the charger overheating, it was the charger cooking the Nexus 5 and causing it to overheat and shut down (which I guess is far worse).

Can you give more details? What cable were you using and what AC adapter to supply power to the charger?

Since you're not using it anymore, care to dissect it and show exactly what part caused the problem? That charger doesn't have much inside of it. Just a tiny circuit board and coil attached to a hollow case with some double sided tape (also why I mentioned in the OP that the build quality wasn't as good as the others I reviewed despite it performing just as well).
[Nexus 5 Accessories] Explore3:
I hesitate to post this as I do not like the company selling the qi charger. Dailysteals.com has the LG WCP-300 Qi Charger for $20 shipped. It is not a bad price (Amazon $35). Daily steals claims the chargers are new but I would not be surprised if they are refurbished units.
[Nexus 5 Accessories] mrro82:
Battery monitor widget from the store has an alarm setting. I have mine set to 113 which is where the phone stops charging.

This is the charger i am using http://www.ebay.co.uk/itm/Round-QI-...ories_MobilePhoneChargers&hash=item23352a8d21 and its terrible! Never seen it charge above 500mA and will constantly lose/gain connection even when i position the phone on straight i am going to return it and maybe go for a nokia dt900 this time
[Nexus 5 Accessories] JassyNL:
Thanks for this extensive test! I own the Coiled QI Charger, but my phone constantly drops off and I cannot charge my Nexus 7 2013 with it.

Which charger will fit for both my Nexus 5 and my Nexus 7 2013?
[Nexus 5 Accessories] mmmmBACON:
How about trying to give informative details about your problems so that maybe someone would be willing to help? Posts like these don't add anything constructive. All you did was come into the thread to whine.

I don't know if you read the OP, but you might see that something I mentioned might pertain to your particular issue. Such as something that has been mentioned probably a hundred times in so many different threads... What microUSB cable are you using and what AC adapter?

In fact, if you read the OP, notice how the exact number you said your charger never goes over, is the exact same number I mentioned...

Which charger is the coiled Qi charger?

Also, any Qi charger that you are going to use for both a phone and a tablet should be large enough to accommodate it. The tilted Qi charger is not big enough and probably wouldn't be stable enough for the Nexus 7. I would go with a flat charger with a larger base. Out of the 5 I posted (there are of course tons more online you can choose from), maybe the last in the list, the Rectangle w/LEDs would be appropriate.
[Nexus 5 Accessories] FuMMoD:
The paper thickness test was an excellent idea in order to compare phone cases!
[Nexus 5 Accessories] fedor12:
You may have misunderstood my post i was not here to "whine" but simply hope to help others to avoid this charger with a nexus 5 at least, if this thread had been created before i had purchased mine it would have certainly helped me pick the right one so i posted the specific charger

I have hopefully to help others pick the right one. As to your questions i am using my original nexus 5 plug/cable and i am also using a tpu case that is 2mm at the maximum (most likely less) if you also read the description of the charger you will see its not the typical one with a blue light this one has a red and green light (but not an orange one as stated in the ad) and even the lights don't work properly with them going dimmer/brighter at times i read and watched a lot of reviews on the one with the blue light but went for this one anyway due to it being a tiny bit cheaper which i regret obviously, also in your OP you said yours got up to 768mA? Mine goes no higher than 500ma and that is a maximum, its more like 200-300mA and sometimes going minus around 300mA
[Nexus 5 Accessories] mmmmBACON:
Well you should understand that seeing the same type of posts over and over again saying nothing but basically "X charger sucks, it's slow charging" with no additional information starts to make a person feel jaded. Having to answer that same question again and again, and ask for the same details again and again. It gets old fast, and 9 times out of 10, if a person just read the OP, their problems would be answered.

Despite your intent, your post insinuated the exact same thing as the others. "X charger sucks, it's slow charging" and you gave no vital information. So apologies for lumping you in with the rest, but since you were attempting to help, then details are much more important when trying to do so.

When buying a Qi charger, the most important things are as follows:

1) Output Current - This is the most important! If it doesn't explicitly state 1A output current, assume it doesn't. Don't buy it unless you know it does.

2) Micro USB cable - Most Qi chargers include a cable that doesn't support a high current, usually you need to replace it.

3) Adequate AC Adapter - 5V 1.5A/2A are generally the requirements, so ensure your AC adapter provides adequate power.

For example, this is a Qi charger you DON'T want to buy! http://www.ebay.ca/itm/Qi-Wireless-Power-Pad-Charger-for-iPhone-Samsung-S3-S4-Note2-Nokia-Nexus4-EP98-/121292675226?pt=US_Cell_Phone_PDA_Chargers&var=&hash=item1c3d9b589a&clk_rvr_id=607613965910

It looks exactly like the Q5 Puck in the OP, but if you read the details it has a rated output of 500mA, which would result in a charging current of about 350mA - 400mA max. The Qi charger you purchased doesn't specify the output current clearly. So my guess would be, you possibly have the same one as the one I just listed above. It is also about $4 cheaper than the normal Q5 Puck charger.
[Nexus 5 Accessories] fedor12:
I think the seller changed the listing as when i purchased it it clearly stated output 1a and input 1.5a when i asked if its better to use a charger over 1.5a or under they told me under is that right?
[Nexus 5 Accessories] mmmmBACON:
No, you want an AC adapter that provides equivalent or higher. If you have a 5V 2A output AC adapter, and your Qi charger required 5V 1.5A input, the charger is only going to draw what it needs from the AC adapter. AC adapters don't push power. It's better to have excess than not enough.
[Nexus 5 Accessories] fedor12:
They must have got it wrong then as this was my initial thought that like the phone the charger will only draw what it needs. One thing i get a little worried when charging with qi is that since the current is lower than an ac plug will this affect the phones battery in anyway long term? I have heard that when charging a phone using a charger that's a lower power than 1a will have a negative impact on the battery compared to one that provides over 1a not sure if this is true or not
[Nexus 5 Accessories] JCreazy:
Does anyone have an Ebay link for the Q8 charger?
[Nexus 5 Accessories] bradputt:
What you say it's correct, the phone controls the current it draws, the charger only provides it.

But you must take note that the higher it draws the hotter gets.

Heat kills lithium batteries. So I avoid charging my phone from zero to one hundred percent on wireless charger
[Nexus 5 Accessories] fedor12:
The seller replied to me with this

Many thanks for your message.

I have confirmed with our technician personnel just now, he said that the problem is your phone's current is so large, and our charging pad can't supply enough current to your phone, so during the charging process it will disconnect.

But our technical personnel have let our factory to reproduce a new kind of this charging pad which with strong current.

Can you test it for us? If it succeed, it can solve your problem, and we will not have this kind of thing to happen.

If it not succeed, we can refund the full money to you, do you agree with that?

I think that's fair but i dont know if the strong current thing is true but hopefully the 3rd replacement will be ok
[Nexus 5 Accessories] abejoker:
I'm looking for the Q8 ebay link too >.>
[Nexus 5 Accessories] mmmmBACON:
I don't believe that's true. It hasn't been until recently really that most phones charge at 1A and above. A lot of phones still charge at much less than 1A. It won't negatively affect the battery charging at a lower current. It will just take longer to charge.

The Q8 is not available on ebay.

I don't really get that phone current being too large part either. It shouldn't disconnect anyway if the phone isn't receiving its max current, the phone will just charge at whatever current the Qi charger provides. If the charger can only supply 400mA max, then the phone will use that, it shouldn't disconnect...

Anyway though, sounds like a decent deal. Shipping will take a while, but you are getting a replacement that is hopefully improved. And if it isn't, you get refunded. If you don't want to be their beta tester, you could always just ask for a refund and get something else.
[Nexus 5 Accessories] fedor12:
I did originally want a refund but i thought i would give them another chance, i have slight concerns of the charger damaging my phone but i will be keeping an eye on it for the 1st few days charge speed, battery temp etc. Shipping has been quite good with them so far as both the original and the replacement they sent arrived around 8 days later so hopefully it should be here in under 2 weeks
[Nexus 5 Accessories] mmmmBACON:
Yeah, then go for it. It can't hurt to try, and if it is improved then all is well. Shipping of 8 days is pretty good too. Pretty much everything for me that comes from overseas takes about 3 weeks to a month...
[Nexus 5 Accessories] bblzd:
No, your phone won't get damaged from charging slowly. It's actually safer.
[Nexus 5 Accessories] lsquare:
So I read the reviews and I agree with the reviewer that the Q8 have the best design. The question now is whether AliExpress is the only place to buy it from at the moment? Again, I've had no experience with AliExpress before. How do I make sure I'm buying from a reputable seller and that everything will be shipped out correctly to me? I'm just worried something will go wrong.
[Nexus 5 Accessories] dehsA:
[MENTION=3746653]mmmmBACON[/MENTION], would it be possible for you to test how much power these chargers consume when they're plugged in but not charging anything? Similar to the video below?

[Nexus 5 Accessories] toews:
If you don't mind me asking, what cable are you using to plug the chargers into the adapter?
[Nexus 5 Accessories] mmmmBACON:
Those are cables my brother in law gave me. He works in the IT department at the U of M.

If you live in the US, the cheapest cables that support fast charging and high current are the "Premium" Monoprice micro USB cables. They're good and don't cost too much. Just make sure they are the "Premium" cables, and not their standard cables.
[Nexus 5 Accessories] paradoxiumwind:
is there a technical reason as to why the charging points on all these chargers are so small? I have the slanted one, and it's such a pain positioning it exactly in the correct spot to stop constant charging drop-outs that I just unplugged it and put it away in lieu of the cable. Are there any +$15 chargers anyone can recommend that maybe have a much larger area of charging?
[Nexus 5 Accessories] lsquare:
No one here knows?
[Nexus 5 Accessories] fedor12:
I received the new qi charger 2 days ago and it chargers my phone much faster than the previous ones i am now finally getting a little over 700mA only thing i have noticed is battery temps hit 42c around 107-108 fahrenheit I'm not sure if this is normal or not as from my research i see the generic qi puck chargers others have only gets to around 36-38c

[MENTION=3746653]mmmmBACON[/MENTION]

Good thread and very well detailed reviews. I was just about to buy one of these cheap QI charger, but I can't decide beetween Q8 and Rectangle w/ LED (my use would be during the night).

Could you please check if these link are exactly your bought product? Thanks

link1 and link2.

Also, do you think that could exist a Q8 variant with a non-slippery surface? Because in some pics on the same site of the links, the Q8 seems like matte and not lucid.
[Nexus 5 Accessories] mmmmBACON:
Yes the Q8 will still charge through that case. As long as there is no metal in the case, it will charge with a distance of around 6mm or 1/4in gap from the phone to the charger.

Thanks!

Yes, they will work with a case as long as there is no metal between the Qi charger and the phone. I would suggest a flat Qi charger if you have a case. The tilted one will charge fine through it, but some people are having difficulty with the phone staying on the charger when there is a case on the phone. I don't have any issues, but it's just easier with a flat charger if you use a case.

Either of those Qi chargers would be fine. I actually use the Rectangle w/LEDs Qi charger by my bed. I particularly like that one near my bed because it's bigger and easier to plop my phone on it when I'm half asleep. The Q8 is a good charger, but it being a smaller and glossy surface, it's better off on a desk where you can position the phone on it better. If you don't use a case, it can slide around pretty easily and off position.

I have no idea if they will ever have a non-slip Q8 variant. If they did it would basically be the perfect Qi charger for me though.

I didn't buy the Rectangle charger from Aliexpress, only the Q8. I got the Rectangle charger off of ebay.
[Nexus 5 Accessories] pollycranopolis:
Just a FYI - I just received 2x Qi Charger, Q8 from Ali Express. Mine have RED lights, not blue. Unlike the blinking behavior originally described, my unit lights are totally off when not in use and switch to constant on when the phone is connected. They appear to remain constant after phone is fully charged.
[Nexus 5 Accessories] fcisco13:
Just got the first one mentioned in this review, no led's but rom has option for led on while charging. So far it's worked good, need to test it a bit more, thanks for the review.

Just got this PowerBot charger: http://www.amazon.com/gp/product/B00F6SPYJS/ref=oh_details_o01_s00_i01?ie=UTF8&psc=1, not quite within the 11-15 price range, but still pretty cheap at $20. It works fine on both the Nexus 5 and the Nexus 7. I even had the Nexus 5 in the Seidio Dilex case I ordered at the same time, no problem charging through the case.

Inductive Chargers

Impressive post, I love the wireless technology and would like to suggest you to try choetech and this brand is provide reliable and trustable accessories with warranty period.
[Nexus 5 Accessories] paradoxiumwind:
Do all wireless chargers only have a small circular spot at the point where they charge? I have the slanted tower one from ebay, and I find it almost impossible to get my phone positioned correctly to stop it going from charging/discharging over and over, despite the charger itself remaining with the green light on, and it doesn't beep to indicate it has begun charging again. What I want is a wireless charger I can really just throw my phone on and forget about it without messing around for ages positioning it. I ended up just putting it in storage and went back to using the cable.
