So right before I sold my wife's Nexus 5, I had the opportunity to test it out with he RavPower RP-WCN11. It's basically a 4800mAh capacity portable charger like other ones on the market. You can attach a device to it with a USB cord like any other. However, it also has QI wireless charging capability.
I guess you could also say it's like a normal QI wireless charging pad that happens to have a 4800 mAh capacity battery inside.
I know others have referenced the product a few times. Here's a video with it in use.
My wife continues to use the power bank in the car and when we're walking our daughter around the neighborhood. It's held up pretty well.
Current price is $56.99 on Amazon w/ free shipping.

I was reading for a while through the various subforums here trying to catch some info on selecting the "best" qi charger for charging our devices here at home (N4, N5 + some others). Finally after reading this review I came to the conclusion that in terms of efficiency, power consumption and charging time more or less all qi chargers perform equal. There are some exceptions tho, like the Panasonic TM101 with it's moving coil or the Tylt VÜ. Both allow free positioning (more or less) of the devices.
I noticed that especially with a case on, proper alignment becomes very important. So you give up fiddling with tiny microUSB connectors but have to deal with aligning the phone to accquire efficient charging. So I wonder is there any affordable charger out there with multiple coils?

I have almost all the big names out there. I have the nexus 4 orb charger and the nexus 5 charger. The energizer and LG verizon branded one. I also have the Tylt Vu. Now I have the AirDock in the car.
To me multiple coils is a feature and not really required. The only one I have that has multiple coils is the Tylt Vu. Its good, but has a big footprint so that charger remains next to my alarm clock and LG G Watch charging set up. I have the LG verizon charger that my wife uses for the Nexus 4. and I use the Nexus 5 pad at work because that had the smallest footprint. I have used various cases with each of these chargers, including the airdock. From the Spigen Ultra Hybrid to the Nexus 4 replica bumper for the Nexus 5, they all work. Sure the Tylt can charge my phone horizontally, but that's it really. lol.
I guess to answer your question, the cheapest multi coil? Well even though this technically not a mulit coil, it does locate your coil for you on your qi compatible device. Pretty neat IMO.
Panasonic QE-TM101

Here's a cheapy tylt VU clone

And here's a late addtion...the Nillkin 3 coil charger
http://www.ebay.com/itm/like/141370021990?lpid=82
Thanks for your answer. The Panasonic charger is, according to most reviews, not supporting trickle charging. If the device is charged completely the coil returns to initial position and the battery dicharges. In some cases there is also the charging coil repeatedly moving to the device and back to parking position again. Plus for some odd reason it is only available from Japan as direct import.
Tylt VU is way too overpriced, although the concept behind it seems great. Even the clone is too expensive.
So far the Nillkin Energy Stone looks good. Just cannot sind any serious reviews of it. Also only shipping from HK only which could be a problem due to strict german customs here
I received my charger from Choetech yesterday and tested it with my moto 360 as well as a few of my other devices.
I figured that I should post my review (from amazon) up here due to the testing on the moto 360. I have bolded that parts people here will be interested in.
http://www.amazon.com/Wireless-Char...r=1-1&keywords=choetech+fast+wireless+charger
First, this is an amazing charger. Choetech always makes good products.
I received this in 2 days and set about testing it.
I was going to make a video showing off this thing fast charging on a Samsung Galaxy Note 5 but I see that there are already 2 excellent videos up showing that. So instead I will show you the things they did not highlight as much.
OK, the quick charge 2.0 wall plug you can get with this is the best one I have ever tried. Just like the other Qualcomm certified chargers, you will get the self adjusting voltages (12v-9v-5v) to give you a super fast charge. The extra you get with this Choetech quick charge 2.0 adapter is the USB port on it is reversible! This is the first charger I have seen with this and I now think everything should have this.
Ok now to the real reason you are reading this. The charging puck itself is a nice clean looking puck.
It is defiantly thicker than the cheapo ones you get for a few dollars. It has some heft to it making it feel more premium.
It has rubber top and bottom to keep both the charger from slipping on your desk or the phone from slipping on top the charger.
It will most defiantly charge your Note 5 or other Samsung devices quickly.
It will also charge your older devices as well. I tested it on a few LG phones in addition to the Note 5.
I noticed no abnormal warmth from the charger or any of the phones I tested this with. This is a very welcome thing as most of my other qi chargers do have heat issues.
One final thing, I tested this charger on my moto 360 and it charged it flawlessly. Most qi chargers fail here and will overheat this watch, this one did not and it charged my moto 360 from 19% to full in about 35 minutes. that is about 15 minutes faster than the stock charger does.
I received this product in exchange for an honest review, this does not affect my opinion of this product.
The fast charging works for a Note 5 or S6 Edge+, right? As far as I know that's a requirement as the new charger operates at a higher voltage.

It will fast charge at a higher voltage on a Note 5 or S6 Edge+, but will work at normal speeds on every other Qi enabled device, including our moto 360.

Seems they have a cheaper standard wireless charger for other Qi enabled device. Same design but cheaper at 20 bucks.

I have not tried it but I would assume with how well the fast charge one works, the cheaper one should also work to charge out watches without overheating them.
Interesting charger! Are wireless chargers efficient and as quick as cabled chargers? How long does it complete 100% charging your phone?

Just from experience, no science here.
A normal Qi charger will take about 2 times as long to charge your phone as a standard 2a charger.
This fast Qi charger is about the same speed on a compatible phone as a normal cable charger.
The fastest way to charge is with a qualcom certified quick charger and phone, that is significantly faster than a standard charger.
Think I'll pick one up,no overheating,that's worth it alone.
dodocool Wireless Charger, Fast Charge Qi wireless Charging pad for Samsung Galaxy S7 / S7 Edge / Note5 / S6 Edge+ and All Qi-enabled Devices Black
I have a few Qi wireless chargers and a Qi enabled device (Nexus 6) but never use them mainly because they charge at a very slow rate but this dodocool Wireless Charger has Fast charging mode (Output 10W Max) which uses Quickcharge 2.0 so if your device has Quickcharge capabilities you will be able to take advantage of but if not the Standard charge mode (Output 5W Max) for standard Qi-enabled devices will also work. I can say I now use this wireless charger as my primary charger and even use it in the car and I know that sounds odd and did to me also at first after reading it in product description but the charger itself first off is angled downward which helps you to view your screen and most importantly the charger base has 2 silicon rings around it, one on the top and one on the bottom which help secure the charging base while sitting in care and the silicon ring on top of charger not only helps secure phone while on the charger but also protects phone from getting any scratches or wear marks. I must say I’m very impressed with the overall function and looks of this wireless charger and highly recommend it.

First off: love this phone. Already selling my S21 Ultra. However, I found an issue that seems specific to the Pixel 6 Pro.
I have a ton of wireless chargers but most don't seem to push enough juice to even charge this phone. Which is weird, because they are capable of pushing at least 9W but in most cases, they don't even push 5W to the phone, even when the battery is <25%.
I have one fancy charger (moshi Sette Q) which can push 15W per coil--there I can max out at the Pixel's rated 12W if the phone is cool, but only until the battery hits 90 deg F. Once it exceeds that, the charging rate drops down to 7.5W or lower, and the predicted time to full charge more than doubles. Coincidentally it seems to hit that 90 degrees within mere minutes of starting the wireless charge. I'm measuring battery temp (not power) using AccuBattery, and power using various USB meters.
The same chargers, power bricks, cables push their max wattage to the S21 Ultra even if the Ultra is >50% charge. And just for kicks I tried my girl's iPhone 13 mini and it instantly hit its max charging power w/o MagSafe (10W, from what I can see). In other words, there's no specific evidence that there's any issue with my power bricks, cables, or wireless chargers. All are reputably branded and genuine parts and if they work with both the S21 Ultra and the iPhone 13 mini then you can probably rest assured they are not the problem.
So, it seems like the Pixel 6 Pro is doing some severe thermal throttling when wireless charging, and the upshot is that you barely ever get the full 12W Qi charging capability of the phone, and most of the time you end up charging at <7.5W.
Anyone else seeing this? If you're charging wirelessly, how's the experience? Does your battery hit 90 F in no time at all? Does it start to reduce Qi charging current once it hits ~90F?
If other folks are having a fine time wireless charging this phone, and you're getting that full 12W on the reg, I guess it's possible that I have a bum phone. Let me know what charger(s) you're using. But if you haven't noticed a problem yet, you might want to pay closer attention to your charging speeds to see if you're seeing the same thermal throttling.
If it's not just a bum phone, then this seems like a major issue. Big enough to force Google to delay the launch of their next-gen wireless charger, the new Pixel Stand.
I'm seeing the same. New Anker magsafe style charger is 3-4 watts... iOttie car vent gets it to 9-10...
Yes, same problem. I wonder if that's why we haven't seen the Pixel stand.
I'm using the original Pixel Stand and it seems to be charging at about 14W which is the max it can deliver.
I haven't noticed it getting very warm when charging but then I have been asleep
I have noticed a couple of times, lifting the phone off the charger in the morning, it was slightly warm. AccuBattery said it had been fully charged hours before that.
The phone is in a Spigen Rugged Armour case and I just leave it in it to charge.
how do you check the speed its charging at? Ill check mine overnight and see. I bought this one...

I'm using one of THESE and also have AccuBattery Pro.
One thing I found with AcuuBattery is it seems to assume the charging voltage is always 5V
So when I am charging it shows the current as 2.3A x 5V = 12.5W
Whereas the actual charge on the voltmeter shows 1.4A x 9V = 12.5W
Interesting. I just set my phone down at night on a fly-by-night brand qi pad I bought several years ago, and by morning the phone is charged full and ready to go. Don't know, or care, how fast it charges as long as its full by morning. The few times I've had to grab the phone after charging for a while, it hasn't seemed at all warm.
But I'm running on google-free nice clean AOSP. Might be that some of that google spyware is sucking up power faster than you can supply it?

No idea what speed this equates to. Only put it on the charger for a few minutes to see.

The way I've been doing it is via a USB C power meter which is just in line between the wall wart and the wireless charger.
I also have a USBC cable that has a built-in power meter and I get similar results. Another thing you can do is just put the phone on charger you have, then go into settings and battery and just monitor the time estimate for charging. Do you ever see it advertise upwards of 3 hours of charging time or otherwise jump from something reasonable like 2 hours up to 4 hours?
It seems like there's two main problems. Number one that the wireless charging coils are extremely narrow compared to S21 Ultra. So the sweet spot is super small and difficult to find. Number two. Once the phone hits 90° f, then it is throttling the charging speed. And honestly, I don't know if that's a cooling problem or if that's just an overly conservative algorithm. Either way it's kind of ****ed up to advertise 12W wireless charging and then have this type of experience.
I've been using the app Inware to see the live amperage, wattage, and voltage.

Thanks for the tip. I didn't know about that one. I think the problem here is probably related to the overall charging limitations that the phone has. If you look at the other threads in this form, you can see quite a few that are related to slow charging speeds even when using the wall wart. But still this is extremely disingenuous from Google and straight up inaccurate advertising when it comes to charging speeds.
For those of you who have the old Pixel stand charger, IT WORKS !!!
All I want is a full charge by AM, and it usually gets a lil boost charge when I drive my sprinter.
About to look for a new wireless charger, but now using the 30 watt Google plug and cable and phone charges up faster than any I have owned previously, nearly all galaxies but the 6 Pro is noticably better, wired.
