Cheap wireless charging plate

Anybody else tried this charging plate ? I just bought one from eBay and it works 100% with my lumia 820 just by putting it on the mat!

Wireless Charger
Could you tell me what the benefits are when using this wireless charger compared to the regular charger? I've seen some videos about it and, to me, it looks pointless having a wireless charger, which is in fact, wired. The only difference that there is, or so I think, is that you don't have your phone directly connected with the charger via micro usb cable - you put it on the "plate", which is wired to the charger itself and you charge your phone. What I'm trying to say is that either of the chargers limit you by the cable and I don't see the "wireless" in the wireless charger. All it does is save you a second to unplug your phone. Again, that's what I think. Your opinion may be different and that's why I'm asking you to tell me the benefits

a) You can place your phone down and charge it without searching for a cable that's slipped down the back of furniture
2) say you run a café - put these on the tables to allow customers to charge and stop them plugging random ass chargers into your sockets
III) It's a fad, but freaking cool - WIRE LESS charging. Sit and think about that.
Also, it's on a mobile phone, so saying it's pointless is slightly hypocritical as it's attached to a device that's USP was not needing to be plugged into the wall

Thanks just ordered one of the Qi Mats. Pemda obviously hasn't had any failed leads or charger ports. Im on my 5th or 6th lead with my M9, all fail after a while.
On my m7 i have had 3 new charger ports fitted by HTC, no worrying about the charger port on my lumia

Wireless Charging - Mate 7 SOLVED?

My wife and I are getting new phones this year, and we really like the look and feel of the Ascend Mate 7, and in my research efforts, I found an interesting prospect. I love doing research, especially before I buy a new phone. The biggest reason for the upgrade (at least in my case) is to have the ability to use NFC again, more specifically wireless charging. My wife is using a Note 3 that I bought a Qi wireless charging receiver for, and so far it's worked flawlessly. I on the other hand have the Mate 2, which as you know doesn't have any NFC capabilities at all. Recently I have been reading about how the Mate 7 has NFC, but doesn't allow for wireless charging. I found a number of reasons from because of the back cover being metal it would block the signal, to they don't make a wireless receiver for the device, and among others, but I found something interesting that might solve the problem.
I opened up my Amazon Shopping app this morning, and I saw the 'Micro USB Universal Wireless Charger Receiving Patch' in my recommendations list. The description it gave for the item is that as long as your device has a micro USB charging port, this will give any device the ability to wirelessly charge on any Qi wireless charging pad. My first reaction was to jump for joy because I had solved the problem by which also sealing the deal of upgrading to the Mate 7. Here is where I think there may be a snag though. There are quite a few of these on Amazon that all do the same thing, some even come with a Qi wireless charging pad included, but they are all from brands that I've never heard of, and I myself being a very critical person am really on the wire. I hate wasting money, and I'm sure that I am not alone in saying that. So I want an opinion, because having the ability to not only use NFC again, but also the ability to wirelessly charge my device would make me a very happy man. I also love writing, so excuse the long post. Thank you in advance.

I think that would just be a phone cover with a charge coil built into the back and always plugged into the USB port. They'd be available for many phones. It may interfere with NFC, not sure.

A phone cover would have been a bonus, but nothing like that exists for the Mate 7 that I've seen. No this is a stand alone, very thin device. The description definitely details it correctly, it literally looks like a patch. I would post a link, but the app won't let me until I post a certain number of posts. Traditional Qi wireless charging receivers look similar, but they have adhesive fixed to the under side that allows you to attach it to the battery, and they have gold contacts that you match up with the contacts on your respective device. This has a long-ish strip that has a male micro USB attached at the end that plugs in to your device, and you can either permanently affix the patch underneath the back cover of your phone, or allow it to rest on the back cover.

[Review] Qi wireless fast charger base from Choetech

This wireless charging pad is about 3" square and about 1/2" thick with very little weight. The top of the unit has 1 anti-slip strip on each side of the top surface to resist phones from slipping off. USB C connector on one side and charging indicator on the opposite side.
Wireless charging is one of the most useful features of a modern phone due to its convenience and flexibility. When I look at wireless chargers the most important is the charging surface and how accurately the device has to be placed on the pad in order to function. This Choetech charger is very convenient in that as long as you are reasonable close to getting it on the pad around the center of the phone, it is good to go.
The next important feature is its ability to charge through cases, This unit can charge through the thickest of cases, an Otterbox Defender on a Galaxy S6. It easily worked on several other cases that were less thick but were made from other materials.
As it is a fast charge capable device it does require a fast charge capable power supply, which is NOT included, but is likely included with your phone. Other fast charge supplies are available separately. It will function using a standard supply, but not in fast charge mode.
On a personal note, I have developed a grand hatred for bright LEDs which has required me to mask off the LEDs on the Samsung branded charging pads with electrical tape. Apparently they thought they were also making flashlights... This Choetech pad has a much more user friendly experience where the LEDs will actually turn off when finished charging and the lights themselves are otherwise more dim.
If this unit could be improved in any way, I'd feel that some sort of guide or glow could be utilized for the placement of a phone on the pad in a dark room. Other than that, this unit is about as perfect of a charging pad as any could want.
The link to the product where my review is posted on Amazon is here:

they do have a special running on the base at the moment, I suppose the recall is affecting sales or some such.... Although I'm just guessing on that.

I'm planning on modifying the one I have to have neodymium magnets placed in the corners and some metal bits inside my case for them to stick to, but this is experimental at this point. I haven't found a fast charger car mount yet, and I like to engineer solutions rather than buying them.

I have the same one, it works great. However, i don't think you actually need the adaptive fast charger for this. If it is actually 10W as listed, then a 5v x 2A charger would give all the power it needs.
update: never mind, i just tried swapping out for a fast charger adapter, it does make a difference. strange...

This charger pad heated my fathers s5 to the point where the battery expanded and caused the screen to bend

Wireless Charge HARDWARE mod - discussion

ATTEMPTED HARDWARE MODDING - the title may be a bit misleading
Longtime Note series diehard fan here. I absolutely cannot live with wireless charging, that's even more important to me than removable batteries, I have had 2 phones have constant problems with wear on the USB port, and my lifestyle is already adapted around Qi charging, I have multiple wireless charging pads, and have, for the past year, never plugged in a USB cable into my Note 3 except for flashing roms and copying backups to my Thinkpad. Now, I am considering a new phone, and my options are either the LG V20, which has no wireless charging but a removable battery, or an S7 Edge with wireless charging and no removable battery.
As title says, I am interested in getting true wireless charging for the LG V20, not some crappy plug-in wireless charging adapter crap. What I'm thinking is finding some point on the motherboard, most likely on the positive and negative terminals of the charging port, and soldering wires to it, and the wires would be soldered to the exposed contact points of an old Samsung Note 3 wireless charging add-on. The same idea has been implemented in a Oneplus One successfully before. Now, obviously, if there were the wireless charging reciever, the metal back cover would be interfering with it. So instead, I will buy a cheap TPU case so that I protect the battery but allowing Qi charging to pass through. Please chime in, and let's facilitate a discussion here. Also, there have been previous threads discussing this idea, including a thread where LG customer service apparently confirmed that LG was planning a wireless charging accessory (in Jan 2017), obviously take this with a grain of salt. The general idea is that either customer service was giving us a load of crap, or LG V20 has the hard ware to do so, but LG never bothered to develop it.

Similar idea successfully implemented on Oneplus One

Also, something else to note, would wireless charging be Qi or PMA standard? Back in the LG G3 days, the AT&T and Canadian versions (which was basically the same phone) had a PMA reciever, whereas Verizon and other variants used Qi.

Possibly varying by region, but very possibly both. While Qi seems to be ahead there are now quite a number of chips which implement both, attempting to figure out which standard the other end uses and adapting. Since consensus is only emerging slowly that looks like the way things are going to end.

Ok, thanks for replying. So now, the question is, how to proceed? Should we try to implement the mod like the OPO I was discussing in the original post? Or should we try to find the necessary software and hardware to enable purported built-in wireless charging? I personally am in favor of trying to solder a Qi receiver onto the charging port, as my main goal is reduce plugging a cable into the USB port so much, but maybe there is a more elegant solution?
I have attached a picture below with the NFC contacts circled. Do you see any points on the motherboard which could potentially be wireless charging contact points? Or are people suggesting that those 10 random metal dots distributed around the phone, are the wireless charging contact points? Because that would just be hella weird.
Post #19 on this thread is what I'm referring to for a reference image: https://forum.xda-developers.com/v20/how-to/lg-v20-wireless-charging-support-t3486488/page2

Also, here are some pictures of charging ports for LG V20. Do you see anywhere that could potentially be used to solder wires on, to attach to a 3rd party Qi receiver? Personally, I am guessing that only the AT&T variant will be Powermat, everything else, like int'l or Verizon variants will support Qi standard. Knowing LG and their tendency to reduce a load of regional variants with random differences (like the LG G6 wireless charging/DAC/64gb storage debacle).

Anyone else have anything to comment on? If not, I'll probably just solder wires to my charging port once my LG V20 arrives off of aliexpress (which might be a while)

I just got my v20. I'll be poking at it over the next couple of days to see what those points actually do.

Hey, that's great! I have access to AutoCAD inventor, so if you can provide me with the exact dimensions I could try to make a 3D printed model of a non-metal LG V20 back cover, over Christmas break. Hopefully I will have time...

I didn't get anything obvious when I checked with the multimeter. I'm going to probably tear this down on Monday and see if I can find anything conclusive. See if the traces from those points go anywhere.

Ive had a look inside my phone and most of the pins seem to be for grounding, connected through a resistor or capacitor. I dont believe there is any pins for qi charging. Look at the pins for the nfc, they are located close to one another, the rest are spread out at almost regular intervals to provide grounds for the battery cover. Also, i dont think connecting a qi receiver to the usb is a good idea, it may confuse the port into thinking an accessory is connected, and i dont think the receiver would like getting backfed 12v when you connect the phone to a QC charger. I think Real qi charging seems unviable for the v20, Unless someone has a service manual to check the schematics.

I wish I had seen this before taking my phone apart. I didn't see anything from the pins going to any of the chips on the board either. Dunno why they skipped wireless charging on the v20.

Qi adapter, Qi charger and corresponding case

Hello,
Buying the 8T in place of the Pixel 5 I knew I had two flaws to cover.
1. The Google Camera which is obviously done by one the many ports out there and
2. The wireless charging.
For the latter, is there a manufacturer who does a Qi adapter to be placed in a specific cover with a carved placing ? That would be it!
Also, I tried a 10W adapter bought on Amazon. It was indeed charging at a 10W "speed" but I couldn't let the phone on the wireless charger the whole night like I was doing with my iPhone Xs. It was buzzing and hot as f***. So I returned it. Maybe a 5W could be better ?
So a software switch could be the thing to disable it. Or a couple made from the adapter and the wireless charger ?
I think all available models are far from what is available when the charging coil is integrated inside the phone.
Any ideas ?

Does my question really interests no other 8T owner..?
