TechMatte wireless charger

Guys from the TechMatte kindly provided me a Qi wireless charger (currently on sale, $24.99 with free shipping) for tests and review.
I'll go step by step to review this charger.
1. Packaging is very nice (especially compared with a few "noname" qi-chargers from the Chinese ebay sellers). Charger came with power supply, cable and simple documentation.
2. Charger made of the good (by haptics feelings) plastic (it's a really nice to touch - I'm not kidding). It's lightweight but not a slippery so it's good for the night stand.
3. The power cable is bit thick and may be a little short but it's OK (actually you may use any standard cable, if you want)
4. Charging: 'cause this charger has just one standard coil and detection sensor, you should put your N7 very accurately to start charging. I've got best result by putting my Nexus 7 as on picture.
Fortunately, charger has a nice feature: it makes a very light "beep" when start charging, so you may adjust your Nexus by listening.
Charger also has a tiny light diode (red: standby, white: charging). It's visible but very small and not annoying (even at night time).
I've successfully charged my N7 (2013) with Poetic Slimline case (as shown on picture). Charging rate is a little slower than using Nokia's DT-900 (but DT-900 has a 3 charging coils).
A few words about TechMatte company: these guys are well aware of their products (that they sell); they can consider customer's opinion and suggestions. Hope to see a special "tablet super Qi-charger" from the TechMatte soon...
So, my conclusion:
pros
- good, non-expensive product shipped from the local (US) company; shipping is fast!
- charger has a nice features: non-annoying audio- & light notifications; good plastic case;
cons
- charging area isn't large enough for N7 (IMHO), you should develop a habit to put your N7 properly from the first try.

is it only for nexus 4

Hmm, did you read my post and have seen my pictures? I'm charging my Nexus 7 on it

It's the Nexus that makes the beep, not the charger. Mine is the cheap Chinese one with no leds, and the Nexus beeps when the charging is initiated.
It fully charges my Nexus 7 over night.

Nope, wrong Both, charger and N7 making the beep. Charger makes beep when it detects qi-receiver (on start charging process); Nexus 7 makes notification sound (btw, I already changed that default annoying sound - you need root for this).
P.S. I had two cheap Chinese chargers (as an add-ons to my bunch of DT-900 plus new TechMatte's); one sent back because of diodes are too big and bright; second stopped working after three weeks (fortunately seller will send me a replacement for free - right after opening case on ebay ) So, I'll stay away from the cheap noname Chinese chargers - finally they costs too much for me

Does this charger stop charging completely after a device is full (IE: is the device not full when you wake up)? Or does it continue charging and "topping off" so you wake up with a full device?

Nillkin Energy Stone Wireless Qi Power Charger Charging Pad + Leevin® NFC Tag

Just found this while browsing wireless chargers and it looks pretty good. I've been looking for a qi charger that it also at an angle so that i can use my phone as a clock at my bedside. I didn't want to spend the $70 for the Vu angled charger and the nokia 910 i have heard some mixed reviews about. I'm not as handy with wood or 3D printing as some others on here but I sure can do a mean job at browsing thru amazon:good:'
I'd like to point out my 2 favorite things about this product. First is that it's at an angle to it lets me still view my phone while at my bedside or desk. Second is that they have put 3 charging coils inside(like the Vu) to allow for better charging when phone position would be funky or just not practical on most other Qi chargers.
well I haven't purchased it yet (due to funds) but if someone here on XDA has it then feel free to post your own pics and review.

Hi there!
I'm from Bombay, India and I just recieved delivery of the NIllkin Energy Stone this evening.
Although I did notice quite a few micro scratches to the border of the pad, they should really wrap it in plastic to avoid this.
Apart from that the time it takes to charge is really long when you compare it to you standard USB wall charger. I use a Nexus 5 with the Energy Stone and since it has 3 induction Coils it really will charge it from just about any angle you can think of it's not very fidgity which I absolutely Love!
It Looks the part with the bright Blue LEDs blazing in the background on the surface of the charging pad area(Indicating that the phone is indeed charging)
I'm still waiting to see the LEDs glow green which means the phone is fully charged. This could very well be a myth...
I had to pay the equivalent of $56 in my currency of Rupees when it actually only costs $39 on amazon!!!
All in all a good experience with this product since it's my first wireless charger ever so I'm pretty stoked about it!!!
IMHO you should go ahead and buy it no questions asked coz it works perfectly and looks proper wicked

RAVPower Qi Wireless Charging Receiver Review

http://www.amazon.com/RAVPower®-Wir...F8&qid=1393455689&sr=8-3&keywords=ravpower+s3
After getting my Nexus 5 and getting spoiled with wireless charging, it was quite troublesome to charge via a usb cable when using my s3 as a secondary phone. So I wanted to get a wireless receiver to go along with the Nexus 5.
Packaging
Not much to talk about here, simple box containing the unit with a small plastic wrap inside. No frills.
Build Quality
The receiving tag is very thin, I can't compare it to others but im guessing they are all comparable. I had no problems putting the back cover on. There wasn't a huge bulge were the tag is. There is a slight bump but you would really have to be trying to feel for it to notice its even there.
Performace
Using my Ravpower Qi Charger it detected the tag instantly. There wasn't any time where I had trouble with getting the S3 to start charging. It didn't get any warmer than usual when charging with a usb cable.
I have a Diztronic case on my S3 and it charged it just fine through the case. I've tried other cases such as the ZooGue case had the same results.
Conclusion
For a mere 10 bucks, its sort of a no brainer for the convenience of wireless charging. I been using it for over 2 weeks and never had a problem with it.
You MUST have a wireless charging pad. Ravpower is offering a 20% discount on the receiving tag when you buy a charging pad with it via amazon. Details is under the "special offers" in the middle of the product page.
I recommend the Ravpower Orbit

Do these guys make a Qi receiver for an S3?

Yeah they do but apparently they sold out of the s3. I imagine it'll come back in stock soon

The best deal for a wireless charging pad is from Monster Watts, sold through Vivealive (sp). $14.99, is the WiQiQi charging pad. They charge $5 shipping, first class USPS inside the US. The pad works well. Not much to look at though, but good deal for the $$..
I'm using the RavPower reciever. It works well together. What I have found out playing around with the charger, is that if you have a poor connection between the charger & reciever, you will get the on/off cycling. I have my phone in a Seidio Active case with velcro on the back to secure the phone on the Mountek CD slot car mount I use. The extra thickness of the velcro prevents good reception & I get the cycling. If I remove the plastic frame all is good. If I remove just the velcro all is good. The screen will flash once at charge start, turn off, then flash once when battery full, then turn back off. The phone will then remain on the pad in standby with no cycling.
It all works a treat, I can't wait to get my AirDock for the car to add wireless charging there as well.

Ravpower said it'd come back in stock within a week. Also, I don't have experience with any other Qi charging base, just ravpower and they've worked great for me

Powerful Wireless charger that works with rugged cases?

Hey guys, I had a circle Qi chinese brand charger that used to work with my slim case, now I got a thicker one and the wireless charger simply couldn't handle it, does anyone here knows a good powerful charger that works with thick cases for the G3? (link from eBay would be appreciated)
thanks

anyone?

In general, I think Qi chargers will only bridge about 5 to 7mm, and I don't think there are any more powerful versions. There are a few (Nokia, Tilt Vu, some others) that use three coils, rather than only one, but I think this just increases the size of the sweet spot, not the power.

That is 100% correct, the qi standard is changing so that it can be ~1in away but that won't be until at least next year from what I have read.

General Actual wireless charging speeds with different Qi chargers

Hi team,
If you saw my other thread you'll know that I've not been impressed with the wireless charging speeds the Pixel 6 Pro gets. They advertise a maximum of 12W charging with compatible Qi stands and 23W with their (new, unreleased) wireless charger.
Tl;dr: most wireless chargers won't charge the Pixel 6 Pro at anywhere close to the maximum for any sustained period of time. Even Google's own Pixel Stand (last gen) has issues pushing the full 12W predictably. In comparison, both S21 Ultra and iPhone 13 Mini could consistently pull their respective maximums and were only limited by the maximum advertised rates of the phone/charger manufacturers.
I've since done some experimenting and actual measurements. For each of these measurements, I've ruled out cable/power brick issues by
using the included cable & power brick wherever possible
reproducing the measurement with multiple, high-quality cables
reproducing the measurement with multiple, OEM or otherwise high-quality power bricks
I've also reproduced the measurements with and without cases, and at various battery levels (e.g. <50% charge, etc).
I've also compared what other phones were able to get from these respective chargers, e.g. Samsung S21 Ultra, and iPhone 13 Mini, just to confirm that they were able to pull the expected power from the same chargers. In all cases, for all chargers, the S21 Ultra and iPhone 13 Mini pulled the expected maximum charge rates given whatever the charger could push (and Apple's own restriction of 11W for non-Apple-approved chargers).
Please note, all measurements are approximate since the meters I have are pretty affordable and not high-precision, but they still give a fair idea of what is possible in the real world. Please also note that you should not generally expect peak charge rates when the battery is at 90% charge. Here are my findings for the Pixel 6 Pro's actual wireless charging experience:
Charger make/modelTypical charge rangeMaximum charge (observed)Maximum charge (advertised)Case sensitivityNotesGoogle Pixel Stand4.5W - 12W13W11WMediumThe lip is really small, so it's easy to knock the phone off of this stand, especially if you have a case. But it does seem to get the best, most consistent speeds. If you use a case, you may find it complaining about alignment randomly.Samsung 15W stand (EP-N5200)3.6W - 5.5W6.4W15WNoneFluctuates a lot; slow to ramp up. Coil does not seem to align perfectly but the phone doesn't complain.Moshi Sette Q4.5W - 12W*15W*15W on both coils simultaneously (allegedly LOL)High (hard to align with case, left coil doesn't work at all in many cases)* These measurements are from the right coil. The left coil simply did not start charging most of the time, and was especially fussy about cases. The right coil worked a lot better with and without cases. If you buy this charger you should immediately test the left coil for functionality.Samsung 9W Trio charger4.5W - 5.5W5.5W9WLow (better with case)The main coils on the Trio charger advertise 9W each simultaneous. Without a case on, the Pixel slowly slips off the charger and out of alignment.
I think the numbers speak for themselves, but you can imagine I'm pretty disappointed in these results. I'd love to find out if anyone's getting a better, more consistent experience with wireless charging on their Pixel 6 Pro, and if so, what charger/case they are using. In short, in terms of wireless charging compatibility and experience, the Pixel 6 Pro is a big step backwards compared to the S21 Ultra.

I have the Samsung Trio and Duo chargers, they are awesome for my old S20 and Watch. But yeah it blows for the Pixel 6 Pro. I also have Pixel Stands, it seems like it doesn't charge as fast as Samsung phones though.

Over the last two weeks I've gone down a rabbit hole trying out different Qi chargers and am also very disappointed in what I have seen so far. I've specifically tried to go for ones that say they can do 15w Extended Profile on the wirelesspowerconsortium website. So far I've tried:
Pixel Stand
Spigen Arcfield 15W
Insignia 15w Pad
Mophie Snap+ (magnetic magsafe like one)
ForCharge Slim Wireless Charger 15w
In each case I've used the same Ravpower 61w GaN brick as the source and while they all initially seem to charge pretty fast at roughly the expected 10-11w, they ALL drop to half that (or below) after a relatively short period of charging.
I've tried this with both the Moment case (which has faux magsafe) as well as naked but the results are pretty similar. The charging is great for maybe 10 minutes then just becomes horrible, it can barely keep up when im driving and its on the mophie snap+ charger.

Thanks for sharing your experiences. On the one hand I'm glad I'm not alone in having this issue but it's disheartening to hear that the charging on this phone (wired AND wireless) is such a PITA. On wonders wtf is the real problem? Like, why does this specific phone have so many issues? Is it the custom silicon (Tensor) that just doesn't offer the same level of capabilities as the last Snapdragon? I'm worried that issues like this help explain why Google didn't release the new Pixel Stand at the same time as the phone.
I mean, can you put the phone on one of these wireless chargers and expect it to be full overnight? Generally, yes--as long as the charger agrees with the case or otherwise is grippy enough to work without a case on the phone. But if you are used to the charging speeds of the S21, or just generally maxing out Qi charging speeds which good Qi chargers, then you're in for a disappointment--at least until the new Pixel Stand comes out, whenever that might happen.
Meanwhile: my girl's iPhone 13 Mini charges at the full 15W as soon as you drop it on the Apple MagSafe charger. And it stays there consistently. Last night I charged her phone from 35% to 100% in <2 hours using that MagSafe charger.
