One of the things I was really excited about with the Lumia 920 was the built in wireless charging feature. Since the Nokia charging plate was selling for about 70 bucks (ouch) I decided to see what alternatives were available. I've tried two different wireless chargers so far with mixed results:
LG Electronics WCP-700 - This charger works great and I was able to snag it from amazon for 35 bucks shipped. If you want wireless charging but don't want to pay 70 bucks for one charger, then I highly suggest this model. You can get 2 for the price of one Nokia Charger.
Powermat 2x - I was hoping the community could give me some advice on the powermat. Naturally if you plug the powercube into the phone, it will charge just fine. BUT I noticed that if you put a charging plate on the charger and then put the 920 on top of it, the 920 will begin to go into charging mode, although when i tried doing that, it didn't really seem to be charging at any noticeable rate( I may have been taking the phone off the charger too frequently though). Does anyone know exactly what voltage and amperage the powermat wirelessly charges at? My concern is that the volts or amps will be off and damage could be done to the battery in my lumia 920. Any thoughts?
Good questions! I was wondering the same thing about the different mats out there.
What about the Energizer one?
Also, the LG one apparently beeps a lot...does it do so with the Nokia? When it finishes charging it turns off and lets the phone run off battery for a bit, then turns back on to top it off again, causing it to beep each time it turns on throughout the night. Have you noticed this?

From what I've read, the Energizer QI chargers will work fine with the 920, I just didn't get one since the LG model was a bit cheaper. The LG one does beep, although I haven't found it to be too much of an issue. When I place the phone on the charger, the LG mat will beep and show the green charging icon, and my phone will make the connection noise. I also think the mat will beep occasionally when the phone is charged, since it lets the battery drain a bit, then starts charging again, although last night it didn't wake me up at all while I slept. You could probably remove the speaker from the LG pad fairly easily, although from my experience, it's not bothersome enough to be worth the trouble.

Doesn't the PowerMat use a different wireless charging standard? I thought I read somewhere it wasn't the QI standard.
PowerMat is its own standard.
Not sure where you are, but the plate is $50 and the stand is $70 here.
Might want to try mail-order?
As for other plates, I have a few lying around, but I don't want to risk my phone trying them without knowing. I have 2 plates and a stand, so I am pretty covered.
Philips DLP7210B/10 also works with the Lumia 920.
I ordered a Palm Touchstone off Amazon for $6 and free shipping. I'll know in a few days when it gets here if it works or not, but I read somewhere that it should.
Sorry to disappoint you, but the Touchstone does not work. It makes the charging notification sound, but the battery still drains; it doesn't charge at all.
I have the Maxell Airvolt QI charger. It works but the phone seems to get warm unlike the Fatboy charger I use at night.

Doh!
I really hope someone makes a 12v charging pad to keep in your car. Plug into the cig lighter and lay the phone on the "pad" somewhere in the car. I know the new dodge cars have it as an option now.

There's no reason why a 12v adaptor of sufficient ampage wouldn't work. Just match up the plug and polarity to the DC adaptor that comes with the charging pad.
But obviously a QI charger is not designed for use in a car. QI only recently release their guidelines:
http://www.wirelesspowerconsortium....ermarket-chargers-v-10.pdf?force-download=yes
It seems there are two current wireless charging standards: QI and PMA
Powermat are PMA, and this is a copyrighted licensed standard, i.e., Powermat will get revenue/license on each device. There is a limited trial in Starbucks.
QI is open, and I think a "free" standard. They have public charging spots in Japan, and Japanese handsets are predominantly QI
This is all just what I've recently read, so I'm not an expert or utterly certain it is correct, but it does seem that Nokia 920's are to the QI standard, and so any QI charging plate should work...?

I personally plan to do just this. I figure a Qi compatible charger hard wired into the car, then find a good place to mount it with a thin grip pad covering it. It should work just fine.

Ooooo, my Edge has a little 'shelf' under the console that has a ribbed rubber bottom. And it has a 12v plug right beside it. I bet my husband (the engineer) might be able to wire up a charging plate. He would need to shorten the cord so it wouldn't flop around. But he's very good at that sort of thing.
This is a great idea! He works overseas but I think I have a new 'honey-do' for him on his next R&R. Thanks!

Nice! I'll get one too!
tabletop charging
I personally think it would be awesome to be able to integrate QI wireless charging into a tabletop. think about it, when you sit down at a table for dinner, you usually take your phone out of your pocket, right? what if you could charge it while you eat? why doesn't starbucks do this?:highfive:
i was shopping for a oem Car dock that would work with our phones but also fit any case i wanted to put in the dock so heres the solution im ordering mine this week
http://www.amazon.com/iBolt-Vehicle-Car-Mount-Dock/dp/B008B0WNA6
Did you get it? How did it work out?

I've seen this one on amazon, Kidigi usually makes good quality stuff and - as it looks - comes with the insert as well so it could be used w and w/o case
http://www.amazon.com/Car-Charger-M...2&keywords=kidigi+charging+car+dock+htc+one+x
...comparison with the price of the iBolt ...looks like the same device to me.
I've had the iBolt car dock for a few days now, and it's working fine. It's a little clunky compared to my old Atrix car dock. I don't have a case on my phone, and the clamp on the top seems to sit on top more than grab it, but the phone is snug in there.

Have you had any charging issues with yours?
When it goes into car mode and navigation is on, it barely charges if at all.
I spoke with iBolt and they are sending me a new one. Hopefully this resolves the issue.
I am still curious if anyone else is having this issue.

The issue isn't the charger but the USB cable not being shorted to put phone into AC charging. Pins 4&5 need to be shorted to allow this to happen. I ordered two of these http://www.amazon.com/gp/product/B007F1DV76/ref=oh_details_o03_s00_i00
to go along with this http://www.amazon.com/gp/product/B008B2EFA0/ref=oh_details_o05_s00_i00
and has allowed me to use the HOX+ for hours of navigation and still charge the phone.
For car dock I use this: http://www.slipgripcarmounts.com/SlipGrip-Vent-Holder-For-HTC-ONE-X-S720E-Using-Seidio-Surface-Case_p_130568.html
I agree that the ibolt is a little clunky but i love it. Its really sturdy. It stays in the position you locked it down at. It's easy to dock the phone with 1 hand. I havent noticed any charging issues but i'll keep an eye on that now that you mentioned it.
interesting
and to think i was going to try and mod my Atrix toys to see if i could make them work.. .this looks way easier, wonder why they dont include the proper cable in the first place or if there are any other docks similar

Hello,
Well it's been quite some time but I didn't wanna open a new thread for this.
I'm using the iBolt dock for my HOX for quite some time and as told above it charges really really slow.
You might say it is caused by the cable, makes sense, but the charger I use to connect the iBolt is the geniune HTC car charger, which does charge the phone pretty fast.
Also, I exit car mode when I don't need it and turn the screen off in order to charge more, but it randomly and frequently turns the phone on. Sometimes just the Android homescreen but sometimes it re-launches the car app too. I was planning to call iBolt for this but I do not have much hope for getting detailed information about the output (actually the USB pin design) since there is no information about this on the web sites.
Can anyone confirm that it supports fast (normal) charging? It becomes useless beacuse of this issue.
You can easily check for yourself. While the phone is docked in-car, do the following: Settings>Power>verify that phone reports "Charging, (AC). If phone does not say this then you are in-fact charging at 500mA. The i-dock/HTC Charger must be capable of providing enough current to charge at 1A and phone must state it's in AC charging. If this is not the case, your phone will discharge while being used in-car.
I had the same issue of non-charging when I first got my phone in December. My research led me to the solution I previously posted. I do not use car-mode since the only app I use while driving is Waze. I hope this helps.

Late thanks =)
After writing that message it came to me too and checked it, though it was saying that it is AC charging but I can swear to anything, whether car mode or screen is on, or not, it is not charged in 1000mA mode.. When I directly charged it with the genuine charger, it was fine.
So bought a 2amp car charger, and used its cable, and it works fine now.
May be, the genuine HTC charger CABLE and the iBolt are not quite friendly with each other. I remember Nokia's not launching PC Suite when it was not a genuine Nokia cable, may be a trick like that. iBolt does not like genuine cables or genuine cable does not like oem "sockets"
I had previously made a wireless charging car dock by combining the internals from the LG wcp-700 with an iBolt Alumina ProDock, it worked well for me but wasn't pretty and required 120v power. I had 120v power in my work truck, but I needed a solution for the wife's car, which doesn't.
So, I was finally able to pick up a couple of the Nokia dt-900 charging pads. They were out of stock everywhere around me so eBay was kind enough to provide some for me.
To start, I popped open the nokia charger and it looks like this. The board and charging coils are all one unit that is fastened with screws to the base of the pad.

I needed to lose the base to save the thickness, so I removed the screws and used 3m mounting tape to hold the board/coils to the face of the pad.
Then I removed the small cover plate from the car dock, again to save thickness. Never mind all the holes cut in the car dock, that was for the previous version.
Then I just used more 3m mounting tape to hold the charging par to the dock, and this is what we have. All that's left is to wire it up to 12v power, it only takes .75a so you won't need anything special. I wired off of the constant power for the stereo with an inline fuse. I wanted constant power so the phone could charge with the key off.
Not exactly elegant, but it's much better than my last version. The reason for all the thickness reduction was so that the arms of the car dock would be long enough to hold the phone with a case on it, an Otterbox Commuter case to be exact. And it works quite well, here a video of me testing with the wife's phone in the case. It's a little awkward to get in the dock because with the case, it's a very snug fit in this dock, definitely wouldn't hold anything larger.
http://youtu.be/Wl3ZFquNqJE
So, I think it worked out okay and was pretty simple to do. It's a little costly with the dock being $30 and the charger being $50, but it's worth it to me to save plugging the phone in 10 or more times a day. I have had more than a couple phones usb ports get broken from abuse over the years, so if I can reduce that risk and add some usefulness, I certainly will.
Really nice job:good: I'm curious how it does on charging? I guess what i want to know is does it actually charge well when streaming music using nav and say making a call heavy load i guess ????
Looks awesome! Nice work. Two questions though -- what brand of dock is that and where did you get it?
I'm currently using the Nokia charger in my car with a power inverter. That works fine enough for me and I intend to stick with it rather than hard wiring. However, my mounting solution leaves something to be desired. I'm using an Exomount right now. I just put the Nokia pad in between the clamps and then set the phone over it. It works okay when driving, but each time I take the phone out, the Nokia falls out as well. Would love to pick up the same mount you have.
Thanks for the kind words, as far as charging speed goes, it's about equal to the cheap car chargers. I have no problem streaming Pandora all day and taking 20-30 bluetooth calls through the stereo. I don't use navigation much, but I think if you were running nav while streaming with the screen on high brightness, you would be lucky to hold power.
The dock is from iBolt, called the Prodock Alumina. It's about $30 on Amazon right now, that and a little mounting tape is all you'll need.

I too cracked open my nokia charger just to see what the insides were like(we all do this right?). Its basically the same insides as the palm touchstones, but just much larger, in the palm charger it was a small coil, maybe 1" in diameter. So it got me thinking, as they were both basically the same coil, just exactly how hard would it be to create your own coil. Like say you use that charger, find whatever wire you would use for this application, remove the existing coils and splice in your own. I need to research a little more, mainly what type of wire is needed, but it looks like you could maybe splice into the existing wires from the nokia board and just make your own, larger coil. I would try, but I don't want to mess around too much with my $50 charger lol.
From my understanding the tech isn't too complicated, its just an alternating magnetic field between the charger and phone that is what does the actual charging. Its not some magical stuff, just a current running through a wire. Maybe the larger the coil the bigger the current need, I don't know, anyone else want to try this

I'd be interested to try something like this, trying to create a bigger "sweet spot" for the phone to rest. The Nokia version, as you all can see has 3 coils and it is pretty forgiving as to placement. The LG version on the other hand only has one coil, and in my experience was a bit temperamental about phone placement, especially with a case on it. You'd have to find out what the exact spec is for the wire, then you could freely experiment with different sized coils. I have no idea if this wire is special so someone smarter would need to figure that out.

Indeed the nokia charger has decent amount of give when it comes to placement. For future reference, the size of the sweet spot on my wooden nightstand is 6.5"x3.5", and keep in my that's all while going through what id say is probably 1/8" of wood, and the fit isn't exactly flush with the bottom of the board. The size of the spot is great for easy placement considering the DNA is just a little over 5.5"x2.5", so I have nearly 1" of space to play with.
Id like to see someone find how large the "sweet spot" is for a single coil while going through different materials too. That way we can find out how much area a single coil can cover or see if overlapping them(like the nokia) can make a difference in terms of area coverage. So that way if we ever want to create something like an entire charging surface on a desk we can know if a single large coil would be need, or just a few well placed small coils would be suffice.
I might post a picture stand, but its not pretty lol. It was just something is just decided to do on a whim, and is still a little rough, but it works really well.
Comparing the Nokia 3 coils to the LG 1 coil, it's obvious that the LG sucks.
The LG pad is probably .75" larger than the phone in each direction, but I only have about .25" of forgiveness from center. It's a pretty small sweet spot. This is with a commuter case on though, I'm sure it's better naked. Because of this, I switched to the Nokia dt-910 for the night stand, plus it holds the phone up so I can see my alarm to hit the snooze.

Curious how you are powering this JTNiggle?
I know the pad gets 12v from the included charging brick. Do you have a regulated 12v source? Or does the charging pad seem to deal with the 14+V you get while your car is running? If it can deal with the extra voltage, that'd be pretty awesome. Just a straight wire to either a CIG plug for portability or even to a fused source for permanent install.
I really want to make something like this. I never use the charging pad for many of the reasons listed around the net. Esp for end of the day things when my battery is pretty low and I want to keep using. I have found some regulated DC-DC set ups. The ones that come with multiple tips...but I havent checked to see if one will fit the charging pad.
Oh..one other question... When you assembled the charging pad, is the 3M tape between the cover and the coils? Or is it between the cover and the back of the board. If its between the cover and coils, do you think you could get it back apart again if you wanted or would it destroy the coils?

It's wired direct, in line with the stereo constant power. I only see 12.6 to 13.1 volts there, the pad has had zero trouble.
The mounting tape is between the coils and the face as well as between the board and the car dock. The tape isn't that strong, it's rated for about 2lbs with a 4" strip and only used 1.5". I was able to disassemble the first version vairly easy.

Great Job...Glad to see more interested in expanding the wireless charging spots. have a question about you running power to constant power, did you put a power switch between that connection? The pads etc do draw power even when not in use, they just use less then say a a/c wall adapter for old way of charging.
It's like any electronic that can be controlled by a remote, even though the unit is off, it stills draws power to be on standby to be able to receive the remote command. As these pads are always looking for that Handshake to start sending power to receiver of the Wireless Charger. This is the only way it would be able to activate itself....Eventually draining your vehicle battery....
Thanks and good luck...

Yeah the only units that would be able to have a larger area to accept charging is the multi coiled pads. The simple basics for Induction Power is that the Receiving Coil is of Exact Size of the Transmitting Coil. This was proven by Tesla over 100 years ago and hasn't changed that Basic need since then.
The Palm Touchstone coil in battery cover is just under the size of the Charger Disc you put the phone on. The Touchstones don't have a circuit board in the design as do other Designs which is needed to do the Handshake between the receiver and Transmitter parts so that charging begins in order to make this safe and not activate by something metal etc coming in contact with the charger.
Like placing a induction abled phone on a Induction Cooktop, it will detect that it is induction and metal parts inside the phone and it may start up but then shut down which is a Good thing for your phone not becoming a melted hunk of junk...LOL...
Someone put a kila-watt device on a charging pad, and said that it drew 0 across the board until the phone was placed on it. Here's the link.

Hoping that is true, because I wasnt going to put a switch on mine in the car. I still think I might just install a cig plug on mine in case I take my wifes car and want the mount. But maybe Ill get a cig plug with a switch built in so I dont have to unplug. I have a jetta...so it has all sorts of power feeds that act in different ways (always on, on with key, on for a timed period, etc).
I was just concerned about seeing the close to or over 14 volts when running. But its sounding like that might not be an issue. I measured the output of the wireless pad's power brick and it was a pretty constant 12.19 volts. I cant wait to tinker with this.

Hey, Sorry their are people out there that refuse to listen or believe Tested Facts and push their own Opinions as Facts...lol...Below I got the info for you from the Qi standard Group and other Groups also supply the Technical Specs on this Technology...Enjoy..
*********************************************************************
Wireless Power Efficiency
The energy consumption of battery chargers has two main contributors: charging efficiency and standby power consumption.
STANDBY POWER CONSUMPTION
Unfortunately, many people leave the chargers and cradles connected to mains power when the charger is not used. The standby power consumption (also called “no-load power consumption”) is significant. A simple calculation shows that power consumed in standby mode is about the same as the energy consumed when loading the battery.
We assume that many people will also keep their wireless battery chargers continuously plugged into the mains. One of our main design goals was, therefore, minimize standby power. Go low!
We did go low. In the mean time we have demonstrated a system with only 0.0001 Watt (100 µW) standby power consumption. And that is probably not the bottom.
An estimate of power consumption by wireless chargers.
WHAT ABOUT WIRELESS CHARGERS?
Our wireless chargers also contain an AC-DC power adapter. Let’s assume that is has the same efficiency (72%). Let’s also assumes that it has the same standby power (0.12 W). [footnote: Wireless chargers can have a much lower standby power, but this keeps the comparison easier.] The transfer efficiency of the wireless power link is typically 70%. And assume that the wireless charger replaces 2 wired chargers. The total energy consumption is:
•charging: 1 hours * 4 W / 72% / 70% = 7.9 Wh (we are now charging 2 devices simultaneously)
•standby (no load): 23 hours * 0.12 W = 2.8 Wh

easiest way to check if it's still receiving power while the car is off is simply place the phone on the dock and see if it charges with the engine off. if it's wired with the stereo's negative wire as well (you only stated wired to the constant power) than it wont receive power until the car is on acc. or on anyways. that should calm down anyone's fears about it draining the car's battery while you're gone.

He wanted to have power always, that's why he chose the constant-on on the head unit which is always hot to keep clock and/or memory or Like My Jeep's Infotainment that has to have a constant on so the Hard drive can shut down properly etc.
But that Kill-a-watt post he read, the guy tested it and it shows 0.00...
***************************************************
The Manual for the Kill-a-Watt ez:
Kilowatt-Hour display:
1. To display the total consumed power in Kilowatt-Hours, press the MENU key until “KWH” is indicated in the display.
2. Consumption will be displayed in Kilowatt-Hours (from 0.01 KWH to 9999 KWH). As KWH accumulate, the decimal point in the display will shift to accommodate a full reading.
*****************************************************
The problem is the reader only reads to a 0.01 kwh which this unit is for Home meter testing of kwh usage times Power company rates...
And the tester needs to read down to: From the test site and results from the lowest possible/available from their design tests:
(we have demonstrated a system with only 0.0001 Watt (100 µW) standby power consumption)
I DEF wont be wiring it to constant on power. It'll be switched. My little insert about my jetta was just me brainstorming...that car has some power circuits that are on timers. So without the keys, you can turn on the stereo for a pre-determinted time, etc. A few more options if I decided to hardwire. Having a switch on the power plug would be nice if I use my wife's car, as both her cig lighters are constant on.
In the end...Ill be wiring mine to a plug so I can move it from car to car easily. Just like a GPS. I just picked up a regulated DC-DC adapter that Im going to test. Says it holds 12 via IC control, and it comes with a tip that SHOULD plug right into the power pad. We'll see. I can always fall back on wiring it straight.
And the link I posted...That guy's test is still pretty useful. Its showing that its not exactly sapping energy when not in use. I guess some other charger power bricks pull some measurable power when left plugged in..? I think .0001 watts is pretty insignificant dont you? Even if wired straight to the battery it would take quite a while to drain it any significant amount. Unless Im misunderstanding things...which happens more than I like to admit
Regardless, it wont be wired to any constant source, at least in my car. So it should be good. I cant wait to get my mount and try to fit everything together. Little projects like this are fun!

Yeah just find the RAP Fuse etc, (Retain Accessory Power) and connect their...It works great. You may even have the Option like My Jeep does and change the Time-out minutes to suit your needs.....Yeah what he did was Great, and I did give him a Compliment on his work, problem is just that the Kill-a-Watt is for A/C power meter tests/results and the device being tested is D/C power...kWh is a measure of energy, whilst kW is a measure of power...
•a kW is 1000 W and a W is 0.001 kW;
•a kWh is 1000 Wh and a Wh is 0.001 kWh;
•a MW (megawatt) is 1000 kW and a kW is 0.001 MW;
•a MWh (megawatt hour) is 1000 kWh and a kWh is 0.001 MWh
Yeah this is Fun Stuff isn't it???/ LOL...right now I'm doing custom install of a double charger and a single charger, wireless chargers, in my jeep. I'm Hiding the double charger to the underside of the tray inside the center Console and single charger underside of the Tray on Driver's side. You won't be able to see that their is a charger in each location....
Like to see what you do when you get it up and going....

Great Job...Glad to see more interested in expanding the wireless charging spots. have a question about you running power to constant power, did you put a power switch between that connection? The pads etc do draw power even when not in use, they just use less then say a a/c wall adapter for old way of charging.
It's like any electronic that can be controlled by a remote, even though the unit is off, it stills draws power to be on standby to be able to receive the remote command. As these pads are always looking for that Handshake to start sending power to receiver of the Wireless Charger. This is the only way it would be able to activate itself....Eventually draining your vehicle battery....
Thanks and good luck...

Yeah the only units that would be able to have a larger area to accept charging is the multi coiled pads. The simple basics for Induction Power is that the Receiving Coil is of Exact Size of the Transmitting Coil. This was proven by Tesla over 100 years ago and hasn't changed that Basic need since then.
The Palm Touchstone coil in battery cover is just under the size of the Charger Disc you put the phone on. The Touchstones don't have a circuit board in the design as do other Designs which is needed to do the Handshake between the receiver and Transmitter parts so that charging begins in order to make this safe and not activate by something metal etc coming in contact with the charger.
Like placing a induction abled phone on a Induction Cooktop, it will detect that it is induction and metal parts inside the phone and it may start up but then shut down which is a Good thing for your phone not becoming a melted hunk of junk...LOL...

I do not have a switch for this charger wired in, I did not see the need. The amount of power that this unit draws while not charging is very minimal and the vehicle is driven daily, so we have not had any trouble. I need to make a second one now to put back in my work truck, where I will just wire in line with the existing 12v accessory outlets as they are on 100% of the time. I just like being able to park the car and leave the phone charging if I need for a few minutes or an hour if necessary. If you have to leave the key on then you have a whole bunch of extra accessories trying to run at the same time and then you may kill your car battery trying to boost your cell battery,
For multi coil wireless chargers, I thing we will eventually see them built into all kinds of things, at least I hope so. We have that JBL charging speaker, which is way overpriced, but a more basic clock radio with charging coils on top would be nice. Not just one spot, but say the whole top had coils in it and you could set the phone anywhere. Laptops could have an area below the number pad with a coil or 3 in it, that would be great too. It seems to be useful enough that a few people here have cut wireless charger into their desk or night stands, obviously there is a desire for the tech to grow, so I'm sure it will only keep growing in the near future. I think I may end up building one into the kitchen counter for the wife, she likes to use the phone for recipes and music, so it would be great if I can find a neutral spot that isn't too likely to get wet.

Hey guys! Bought the official samsung charging pad today, for novelty factor more so then anything else if im honest! It was €55 to buy online here in Ireland (which is crazy money) but i got it along with a case for only €40 as part of a deal so i thought why the hell not. It came without a cable so naturally i assume i must use the fast charge cable with it? Here are a few questions i have.........
If using the fast charging cable with it , does that mean i will be getting fast charging capabilities from it? (iam assuming not)
If its generally not a good idea to use fast charge plugged in over night then does this apply to the wireless pad in conjunction with the fast charger?
And lastly. Can i run the cable from the usb port on my computer or does it have to be plugged in to a socket when using the wireless pad? The answers may seem obvious but just asking none the less! Not taking any chances with this baby ha
I have four of them. Two of the small rectangular ones from last year, and two of the newer round ones from this year, so I'll take a stab at your questions.
If using the fast charging cable with it , does that mean i will be getting fast charging capabilities from it? (iam assuming not)
I have not seen, nor did I expect to see, any difference using a fast-charger vs. standard. As such, I only use standard charger adapters for wireless duty.
If its generally not a good idea to use fast charge plugged in over night then does this apply to the wireless pad in conjunction with the fast charger?
My S6 Edge stops charging while on either version of the wireless charging pad, once it reaches 100%. The light on the (newer, round) pad goes from blue to green once it has reached this point.
And lastly. Can i run the cable from the usb port on my computer or does it have to be plugged in to a socket when using the wireless pad? The answers may seem obvious but just asking none the less! Not taking any chances with this baby ha
Unless your PC can source 2A from the USB port, then, no, you cannot use your PC USB port to power the wireless charging pad.
Any idea where i could get a longer geniune samsung charging cable so? I bought the wireless pad for use at a desk but the cable on the fast charger is too small to reach from the socket to the desk! I would need the cable to be at least another foot or two longer
Questions belong in Q&A, not General.
Thank you.
I have a question I'd like to add!
I've never used wireless charging before, can you use it on the s6 edge with a case on the phone? Does this impede the wireless charging? Thanks!

Impede? Yes.
Any distance between the surface of the charging-pad and the back of your phone will impact the wireless inductive charging. The less, the better.
Also, obviously, any case that includes conductive materials will be a non-starter.
That said, my Speck case and my wife's (brand unknown at this moment) case work satisfactorily with both the Samsung round and rectangular charging pads. I have read that there are people that have had poor wireless charging experiences with some (probably thicker, more rugged) cases.
Searching should find the specifics.
I am trying to charge my LG v60 tmobile in my 2021 Prius prime. it has magnetic charging pad. the phone start charging but then the charger start flashing light in few seconds that phone is not charged. no matter how many time you tried it wont charge. I remove the cover and try every other way to charge but it wont charge.
took it to Toyota they tested and finally said its your phone the charging pad is fine.
anyone experiencing the same or have any idea please share. thank you
In my experience, this phone is picky about chargers - both wired and Qi. I found a great holder & wireless charger similar to this one, then paired it with a high-power 12v adapter. Unfortunately, neither of these are available any more. But you should be able to find similar products that, when combined, will give your V60 enough juice. I can't recall at the moment, but it may also be high-speed wireless charging -- something even harder to do with this phone.
You could also try removing your phone from the case if it's in one. A bare phone will get it into closer proximity with the charging coils.
I don't know how the magnetic charging pad is wired in your car, but perhaps there's a way to get it connected to a higher output 12v circuit. Check YouTube or the car forums, etc.

It charges at home with qi charger and wired both ways.
pits the car pad that stops charging.
I have tried everything with and without case the result is same.
toyota said the car pad gives as much juice it wants it’s interactive. But it’s your phone not syncing with pad.

Not syncing doesn't seem like much of an answer, and doesn't explain why it's not charging. Did you check the car forums?
