Wireless Charger Question

I've had a Nexus 7 since they launched last year and I just got the new one on Wednesday. I'd like to get a wireless charger, will any wireless charger work or do I need to look for specific attributes?

As long as it is designed for the Qi standard it should work. I have a LG WCP-300 and I used it to charge the Nexus 7 I bought for a friend. It worked fine, but since it's so small the tablet was poorly balanced on it. That charger is at some Verizon stores for $40 + tax, and Verizon online for the same price with free shipping. The WCP-300 comes with it's own power supply.
I have seen good reviews for the new Samsung wireless charger, it's $50, but it may still be available for half off. You'll need to get a separate power supply, but I think it probably needs to be 1.8 or 2 amp output. It's also larger, so the tablet won't tend to rock or slip off as easily on the LG charger.
You can see threads on both of those qi chargers over on the Nexus 4 accessories threads.

The Panasonic TM-101 is simply fantastic. Toss your tablet anywhere on the pad - and the pad will find it. Will charge multiple devices - sequentially. Nice to have a tablet that is always charged now.

the nexus orb has been great with the 7. my 4 will slide of frequently but I've had no problems with the 7

I bought the Samsung charger with 50% off coupon and so far, it works with original nexus(2 amp) plug, 2013 Nexus(1.35 amp) plug, iphone 4s/5 plug(don't know what amp).
I like that I can lay the Nexus down cross ways to see the charging indicator led come on, also works with i-blason folio case on the Nexus.
So I lay it down to see the led come on, hear the little tone from Nexus telling me that's it's charging, I close the magnetic cover and turns the screen off. I wake up next morning and it was fully charged from ~20%.
So, I'd say the Samsung charger with 50% off coupon is worth it. I think they are backordered right now though.

Any Qi charger should work. The Samsung 50% off deal is nice bout out of stock.
I JUST FOUND THIS, AT&T has the Nokia DT-900 at half off currently. That's $24.50 plus tax.

Another vote for the Orb. Holds it so that you can see the time on it at night if you set Daydream up.

I have read that the Panasonic TM-101 will stop charging once you device reaches 100% then not touch it again to keep up the charge as the phones drains in sleep mode. Something that most other chargers do. That would just bug me.
Even though it cool, I'll be satisfied with the Nokia DT-900 I paid $25 for, and eill keep my device topped off.

Looks like you already made your choice, but I was going to put in another vote for the Panasonic TM101.
I also have a Nokia DT-900, which looks nice and is compact. The only problem is that the Nexus 7 is large compared to the charging plate, and it'll take a bit of practice to perfectly center your tablet onto the charging plate when you can't really see the charging plate under the tablet.
The Panasonic one, as you've probably read by now, automagically positions the charging coil via motors to line it up with your device. The coils light up when they move, so you can visibly see the charging coils as they center behind your Nexus 7. You can hear the motors working, but it's only about as loud as a quiet inkjet printer, so it doesn't really bug me at all.
As far as cases are concerned, you should be fine as long as the case isn't made of metal, and as long as the case isn't too thick. After experimenting a bit with placing a magazine between my N7 and the charging plate, you can get away with about 1/4" of space and still be able to charge.

Also, if you put two devices on the Panasonic, it will charge one and then move over and charge the second. I also read - somewhere - that when one of them drops down to 90%, it will charge again. Unproven by me, since my tablet is always fully charged when I pick it up. Loving it - neatest gadget I have bought in a long time.

I'm not sure what your talking about. I just roughly center my N7 on the Nokia DT-900 and it charges. I'd have to be grossly off for it not to charge. As long as I'm placing my N7 on the charger and not tossing from 2 feek away it works flawlessly. Something must be wrong with either your N7 or your charger.

If that's true, that sounds great. But read or saw a video review that said the opposite. I don't own the Panasonic TM-101, so I don't know which is correct. Maybe someone who has first hand knowledge can chime in.

the link doesn't work, the brand is not mentioned, neither the model... Bad post man

fixed link - http://www.amazon.com/PowerBot%C2%AE-Inductive-Compatible-Including-Smartphones/dp/B00F6SPYJS

Bought this when it was on sale for like $14.99 by the same primo-superstore guys. Great qi charger. It does BEEP when you first put the phone on but doesn't keep BEEPING once the phone is fully charged like some others.
Very low noise beep tho', so not really a big deal. There's also a tiny LED light on the front of the charger for indication. It did not come with an AC adapter so you'll have to supply one. But it did came with a long and a short micro USB cable. I suppose one is for connecting to a wall charger and the other one for your computer. It does charge just phone if you hook it up to the computer USB port, although much slower.
Best $15 buck I spent all year.

Bought the same or similar one from FastTech and am waiting for it to come in. I'm looking forward to trying it out.

Does it keep the Nexus 5 at 100% when you charge it overnight or does it completely stop charging once it reaches 100%. Does the phone/battery get hot when using this charger?

Ya it works with my digitronic case no problem and the beep actually really helps letting you know its charging. Ya I know there is no brand and sorry for the bad link but I have both the official nexus charger and this one seems way better I can just set it down hear the beep and its good to go where the nexus charger I always have to double check the placement when I put it down.

What happens when the phone reaches 100% and you leave it on the charger (As would happen when you're charging it overnight). Does the charge remain at 100%?

Yes it remains at 100% and does not beep all night like other ones it has been working great so far. I read a lot of people having trouble with these types of chargers they would charge then it gos to 99% then back to full and beeps on a cycle all night long but I have not experienced that with this charger. I don't know if this one on amazon is different then other ones sold on eBay they all look the same but so far the one from amazon is good. I'm almost thinking about returning the nexus charger to Google because I don't use it anymore.

I bought one too and I like it a lot. I can charge my nexus 5 (via Qi), Nexus 7 FHD (USB, 2.1A) and Dell Venue 8 pro (usb, 1A) simultaneously while charging the internal battery.

Just ordered one. It says 17-28 days, which is a while, but I'm not in a hurry

Does it have the magnets though that the nexus charger has? That's really why I wanted to buy the nexus one.

I got this last week. I used velcro to stick it to my car mount. I had to remove the rubber rings from the top and bottom to make this work.
It does not have magnets. The magnets in the official charger set it apart from most other Qi chargers.
It works well with my Dizitronic TPU case

FYI - Here's the Fasttech model. I can confirm that this works with both the Nexus 4 and Nexus 5. Fast charging, and no beeping all night. For those people having trouble with beeping, try being more precise with placement... I find on the Nexus 4, that if I put the charger dead center on the body of the phone, it will beep continuously. If I offset the charger about 1/2" towards the micro-USB port on the phone, the beeping stops and it charges perfectly. The Nexus 5 seems less picky about placement, the sweet spot seems to be quite large in comparison.
Anyway, here it is: http://www.fasttech.com/products/0/10006012/1462103-t200-qi-wireless-charging-plate
I bought two, and really need to buy about five more. They're awesome.
Oh, and to answer someone else's question, no magnets for the N5... but flat on a desk and with the large sweet spot, it doesn't seem to matter.

I have this one too. It's worked well for me as a magnetic car dock (had to add the magnets). I hated the Beep sound whenever it became misaligned so I popped it open and found the speaker.
It's the tall black thing in the middle-left of the attached image. If you pop off the top plastic lid of that little black thing you can remove the little metal circle that sits inside it and it stops the beeping. If that's an issue for anyone else...

Hi. I bought the same and works well. I think the bip sound is a good thing because sometimes the position from the phone is incorrect. In this case no bip

Expecting it to be functionally the same as my "puck" charger, so will need a larger PSU (I use 1.2A) to solve the problem of not keeping the phone topped up after its fully charged

There's already several tutorials on how to do it. But I bought these from Amazon and they work great. Needs non-slip grip though so I used one of those silicon Smartgrip dash mats I bought at the container store on top of the magnets. Works great. Here's the tutorial I used though. And a picture of my charger now.

Official Nexus 5 Wireless Charger, First Impressions.

I had the tilted wireless charger already (link bellow) but decided to get the official wireless charger as well.
http://forum.xda-developers.com/showthread.php?t=2611246
Of course its a lot better made then the Chinese charger but is it better in usability and charging speed?
With the Chinese charger I was using the stock nexus charger and cable because they are much better then the cables that came with the charger, more detail in the link bellow
http://forum.xda-developers.com/showpost.php?p=50254993&postcount=116
The info you need to know is that the OEM nexus charger and cable put out about 1000-1100mA while the same cable paired with a samsung 2a block was able to push past 1600mA but not keep it there, leveling out at 1200mA. The OEM block and cable with Chinese charger puts out between 650mA and 730mA
So how does the official Nexus charger compare?
Well to start I tested the new cable with the OEM block and it was putting out just over 1100mA, so we know the cable is better then the OEM cable. Then I tested the new cable with the block that comes with it and got a steady 1600mA and it didnt drop. Now the block itself doesn't say anything on it as to what it puts out, but the charger base says 1.8a, is that what the block puts out? Regardless the block is much better then the Samsung 2a block.
I don't use a case so the phone on the charger itself puts out only a little bit more then Chinese charger keeping a steady 768mA. Now it can drop below and above that number but it really likes 768mA. So while it does have a great cable and block, if all you care about is speed then charger itself is a little faster but not by much compared to the Chinese charger.
As far as usability, I cant get the nexus charger to miss. I can throw it on and it connects every time. With the Chinese one it didn't always connect and i had to make sure i got it in the right spot and make sure, even if I heard the noise, that it didn't disconnect and was actually charging. With the nexus charger I feel confident that the magnets are lining it up and it gets a good connection every time.
As and added bonus, I have heard a lot about how you could possibly charge while vertical attached to a wall. I decided to try this and I can attest that the weak link will be the charger holding the wall not the charger holding the phone, as long as you don't use a case like me. The magnets are more then strong enough to hold the phone vertically, in fact they are more then strong enough to hold it upside down, I tried! The pad that sticks to the surface is just as strong as I've been hearing as well. I literately just slapped it on the wall and then threw the phone up and its holding thus far. I have it only a few inches above my night stand and will update if it falls, but so far it has held up to me taking the phone off and on about 50 times with no issue. I'm not sure how it would hold up as a car mount, only because I don't know how the sticky part of the base would hold up to extreme hot and cold. I image it would probably fall, especially if completely vertical.
I would definitely recommend the Nexus charger over a Chinese one. I you have the $50 then its a no brainier, it was even a couple bucks cheaper then that on amazon and my prime membership got it here on Monday when i ordered on Saturday afternoon. If you only have $13 bucks and don't mind waiting 3 or more weeks then Chinese one charges almost as fast.

I too finally went from the orb to the new charger because I wanted a vertical mount. I'm blind as a bat with my contacts out and wanted to be able to see the time on my phone while in bed. With the orb, the angle was bad and my nightstand is taller than my mattress, making it hard to see. So I got the new charger, put it on the side of my nightstand and it's holding just fine. Holds the phone great too and now I can see the time on my phone. As long as you can get a smooth, flat surface, I don't see why mounting vertically would be an issue.

just wanted to say, it did end up falling off the wall the 2nd night while charging, the charger from the wall, not the phone from the charger. A good sized piece of 3m double sided tape right in the middle of the charger fixed that and I've had no problems since.

Charger in use
Can you advise please if the Google charger cuts out once the phone has reached 100% or does it change to a trickle charge? Looking at some of the alternatives (e.g. on Amazon) I haven't found any that automatically cut out at 100% although a few mention about changing to a trickle charge. What's your experience in this regard?

Have you considered using this charger in the car? From what you're saying, the hold issue seems to be the charger itself. Using double sided 3m thick tape may solve the issue.
The reason I'm curious is because I and many other previous Palm Pre users used to use the touchstone wireless charger in their cars and the phone never fell of even on extreme bumps. It was great being able to simply place the Pre on the charger and if you were lucky you could put the touchstone right in your line of sight (I have an 06 civic so the touchstone fit right next to the steering wheel, to the right. Look at my profile pic or do a search for palm Pre wireless charging in the car and you'll come up with hundreds of results and pics).
Do you think the charger's internal magnets would be strong enough to hold the nexus 5 in place while driving? Right now, I still use the touchstone as a place holder for my 5 as the internal metal discs on the 5 line up nicely with the internal magnets in the touchstone. I did modify the touchstone slightly and added magnets every 90° starting at the 45° position and then the other 3 were 90°apart from the initial magnet. I'll try to post a pic or a video of what I mean. The touchstone is not a qi charger so it doesn't charge but it certainly makes for a super convenient spot for the phone to be especially when using navigation. Also the nexus has not fallen once while driving over some pretty harsh bumps.
What do you think?

Choetech Wireless Fast Charger

Got this to use with my Note 5 but have had success using it with the Nexus 7 as well. I have a video here
https://goo.gl/SHlM2Z
I have multiple wireless chargers. $3 cheapies, Samsung OEM, Spigen 3 coil wireless, and now this. This is by far the best one out of all of them. Just the fact that it has worked fast charging is great because you don't lose the charging speed that typically comes with wireless charging.
I tried this with a Note 5, S6, and a nexus 7. Worked well on all those devices with zero issues. The charger is heavier and feels sturdier than the other ones I have. I'm guessing whatever is inside to enable fast charging must be a pretty dense set of components.
Not sure if it's 3 coil but connects without issues every time. So far I haven't had an issue of having to mind it around to get it to connect. Tried with and without cases and haven't noticed a drop in charging time.
Definitely picking up a second one to leave at my office.

Hi,
does it mean that the fast charge is available with the Nexus 7 ?

Du-Cray

Looks real nice

Wireless charger?

After having a series of Nexus devices for many years, I was initially slightly disappointed that this device didn't have wireless charging as I loved it, as it gave me ability to simply throw the device on the table overnight and forget it.
I do appreciate how incredibly quick dash is... But old habits...
I bought one of these.. As it was so cheap...(£7)
Aventus (Qi Receiver) OnePlus 3T Ultra Thin QI Wireless Charger Adapter Receiver Card
https://www.amazon.co.uk/dp/B01N9CZ7RB/ref=cm_sw_r_cp_apa_6pFOyb7XR00NV
It's frightening thin and light and is hardly noticeable under my case.
Anyone else use these..?
Will they over heat the device?
As dash charging seems incredible in this sense.

If they're made well, they shouldn't really cause any problems. I used to use a Nexus 5 with a wireless charger, then later bought one of those receivers for a tablet so I could use the same charger. I find that even by wireless charging standards, these receivers are slower than normal.

I use a similar unit on my 3T and works like a charm. I couldn't go back to plugging in either after my Note 5.

I have one of those or at least a similar one and one thing I noticed was that it never went into deep sleep because it thought mtp was plugged in. So it stayed awake.
So watch your wake locks and if it seems your battery is draining that is why. Only resolution is to stop using it.

I've got one on my N6P, but mine's an older version with quite a big plug. The actual charging works fine. I was looking to get one with a slimmer plug but I'm worried about it breaking when I'm doing updates via cable.

Keep in mind that the Nexus 5 has a 2300 mAh battery and the 3T is a 3400 mAh battery (48% larger) and the max input doesn't change with devices so it might be "slower" in terms of %/minute but that might just because of battery size.
