Yes, I'm in contact with him, I sent a log of battery status app. Also, he said that the charger surface temperature may raise up to 48 ºC, and it's possible that the phone to be over 40ºC, and the protect mode enter when metrans reaches to 55 ºC.
[Nexus 4 Accessories] Khaiyan:
I believe that's correct. The auto-cool down feature kicks in when the Metrans reaches above 50°C but I find this usually corresponds with the Nexus reaching 40°C. I guess this is not the case with all units.

What's the maximum your Nexus has reached on the charger?
[Nexus 4 Accessories] combatdeity:
Thinking of buying this charger, thanks for the reviews guys, it looks the business, but I have 2 concerns.

Does this charger make any audible hiss or click with the phone either on or off the charger, I only ask because a previous one I bought did and it made it useless as a bedside charger.

Also, is the majority conclusion that it works fine with any 2 amp charger, and that it is required? A bulky adapter on the plug socket would be annoying for my set-up.

Cheers.

The eBay supplier just contacted me saying he found an adaptor compatible with the European schuko plug. No worries for future shipments then! ;)

He will also send me the new adaptor. Can't wait to use the wireless charger after 5 days it spent in the box.

EDIT: The metrans charger works perfectly! I use it everyday with my TPU case on with no problem. The soft spot has ~2cm diameter, so it is easy to align the phone in less than a second. Very happy with the product, would certainly recommend!

Many thanks esskayy! ;)

My experience with the MWT01, once it hits 100% it won't charge again until the phone is removed and replaced

Hissing Noise

I find that occasionally there is an unsettling pulsing hiss that the charger emits.

Can anyone explain the mechanics behind why this happens if this is normal? I fear that this thing might blow up on me.

My experience with the MWT02, once it hits 100%, it will stop charging until the battery level is about 95%. When the device initiates charging, it will make a beep sound.

This means that if you have this beside your bedside, it will beep intermittently throughout the night, take this into consideration when purchasing.

As for the volume of the beep, I am a light sleeper and I can say that this will wake me up during the night.

Hi, got my wireless charger yesterday from China and used it last night for overnight charging. Works just great. Build quality is superb. I'm in UK so can't get the orb but I think I prefer the flat option. Nexus 4 with bumper on and no problems. I think I'll tape over the led as the charging pulse at night although not bright I don't need as it slightly eliminates through the white case. Cool. Thanks for reading my take on this charger.

There seems to be a lot of varying opinions on the sound and light this charger emits. The consensus seems favourable, however, it seems you really have to buy it to know for yourself :)

Personally, and having seen the cheap fasttech chargers, I can say that the Metrans is miles better. The beep is not loud enough to bother me and the light is more of a soft glow. And in regard to looks, this is a definitely a close contender to the Orb.

Do you have a DAB radio? I have an alternative charger and found in interferes with the the radio when charging. Wondered if it was my model or perhaps most Qi chargers that have this problem near digital radios...
[Nexus 4 Accessories] TrIn@dOr:
Please don't waste your time and money on this device.

After a while the phone starts sliding (with or without bumper) and stops charging.

DOES NOT WORTH IT.

I originally ordered through ahappydeal and didn't have the patience to deal with their inventory problems, so I got my refund and ordered through the OP's source. The package was delivered quickly and the quality was of the packaging was good.

The Metrans charger itself is amazing, I can't recommend it enough. I've had it for almost a week and haven't encountered any problems. Just a few notes on things others have brought up recently:

- There hasn't been any hissing or unexpected noise for me while the device is charging

- I haven't seen the LED glow red yet although this might happen overnight since that's when I charge my Nexus

- The LED itself glows with a 'heartbeat' type of pulse, which isn't bothersome to me at all

- The charger is bedside and it doesn't disrupt my sleep or anything, even the short beep when I put the device on the charger is fine

- The 'sweet spot' for charging the phone is really easy to find as long as you're aware that the charging coils are on the lower half of the phone. The vast majority of times I can set my phone down without thinking too hard about where I'm placing it, and it charges as it should.

- It charges more or less as quickly as if it were plugged in

- I don't know the exact heat of the device during the charge, but it does get hotter. However, it's not more than it normally gets but I can't confirm the true temperature (*see below)

- Any time I've picked up my phone after an overnight charge it's been at 100%

- This is one of the nicer looking Qi chargers available right now. Also it's easy to clean and, guess what, your phone doesn't slide off it (assuming your table is flat obviously!)

Overall, I really like this charger, great recommendation OP. Not everyone's will act the same way, but these are my experiences with it so far. If something does come up I'll let you guys know.

Edit: I just had my phone plugged in for the past few hours and it's actually less hot than if I'm charging using the Qi charger. It's still hot in areas of the phone, but wireless charging gets hot especially around the coils, which makes sense. It's not overheated to me, but it's definitely something to consider. So far it's not a concern though.
[Nexus 4 Accessories] Khaiyan:
@ b.spec - My thoughts exactly. Glad you like it :)
[Nexus 4 Accessories] Ruag:
Install Battery Monitor Widget (from google play), add a widget, after in settings/history set a refresh time of 1 or 2 minutes. Before you charge clean the history (menu/clear history).
[Nexus 4 Accessories] Khaiyan:
I usually do not go above 40°C. That's quite a high temperature but as far as I'm aware, all QI chargers (even the Orb) push the temperature to that level, and some even higher. It's one of the trade-offs you just have to accept if you want to charge wirelessly.

I've had mine for 2 month now, just as long as I have had the Nexus 4. Aside from still loving the phone with passion fruit guva, I totally have no problems whatsoever with the Orb.

I'm in the middle of a project where I open the palm Pre touchstone and taking out magnets and fastening them to the surface of the Orb and also using the discs on the inside cover of palm pre's battery cover of fastening those to the back of the Nexus. That way the Nexus will charge in the car like my Pre used to. This will be revolutionary. Everyone will be so jealous and ask a million questions on how I did it. I can't wait till I get this project completed.

My Metrans "Air Box" has finally Arrived!

After reading various posts indicating that AHappyDeal had run out of stock I was getting concerned, especially as my order was still marked as "Processing". I contacted them and, other than the automated response, didn't get a reply, so I chased them a couple of days later and got a reply to say that my order had been dispatched:-

"...Please note that Flat Rate Shipping normally takes between 15 – 30 days to arrive after dispatch.

if you do not get it within 45 business days, then contact your post office and us "

Well, I'm pleased to say that it arrived just under 1 month after ordering and am very happy with it (especially the price!)

On the down side that power adapter is the US type, fortunately I already had an adapter from US to UK so was up and running in seconds.

A point that doesn't seem to have been mentioned in this thread is the Nexus 4's tendency to slide, or move very slowly.

I like to keep my Nexus naked, but the glass back slips gradually over the Metrans' surface until it is out of the sweet spot. Perhaps my desk is not perfectly flat. The slippage is almost imperceptible. When I first noticed it I wasn't sure, so I aligned the phone perfectly and left it for 5 minutes to find that it was about 20 degrees off alignment! The fix is to simply place a small patch of cloth (I use a piece of eye glass cleaner cloth) onto the Metrans first.

Another point is the USB cable that comes with the charger. As mentioned before here it is quite short, so without thinking I replaced it with a longer one from my Kindle Keyboard device. Very quickly I started getting the red light mentioned earlier in this thread. Changing back to the original shorter cable fixed the problem.

Can someone tell me how the Metrans MWT02 is packaged by the ebay seller? Is it placed in a another box? or bubble wrapped then in the a 'polybag'? or in a bubble padded mailer bag?

Having worked at AusPost, I know they can be pretty heavy handed with their parcels so just concerned that it's not packaged enough and might get crushed under other parcels.
[Nexus 4 Accessories] Khaiyan:
It packaged in a small box with bubble wrap inside. It's very tight and secure.
[Nexus 4 Accessories] kodess:
The AirBox had bubblewrap around it, then in the small box, which was in the fedex bag.

The AirBox is really solid and I can apply my upper body pressure on it and it will only slightly bend. The smallbox is also completely covered in tape and is also slightly bendable.

From China to the Netherlands in 3 days. I chose the free shipping.

I have just ordered one from another eBay seller from China as it works out £5 cheaper at £35.29

Seller communications has been good as I asked them to confirm it was the same model as the listing didn't list the manufacturer or model no. I also asked if they could supply a UK adapter and they said they would supply one with it without additional cost.

Had confirmation of shipping the following day so will confirm when I receive it.

I'm curious, do you guys leave your phones on the charger just as-is, or do you also pick them up and use them? I'm thinking about a Qi charger, but sitting here I do a lot of randomly checking my phone and/or picking it up while it charges. I'm a bit worried about going through too many 'charge cycles' just from picking it up and putting it down. Especially since this battery isn't exactly the easiest to replace.

So I just got this from the same seller as everyone else on ebay. Took 1 week and 2 days to get from china to Australia. Not bad.

The unit is awesome and charges really well when connected to AC however I can't get it to charge via usb. Has anyone tried doing this? Am I doing something wrong?
[Nexus 4 Accessories] vodka_redbull:
Most standard USB ports on computers won't supply 2 amps they usually supply only 0.5 amp. This is also why you must use a charger that is rated at 2 amps.

I don't think you will get it to work with a PC.

I agree it is a great price of kit.
[Nexus 4 Accessories] bryanlim05:
Yeah that's what I figured. I was just a bit confused especially when in the OPs review he states

"As you will know, it is USB powered so it can be used alongside a PC USB port or a wall adapter"

If someone could clarify this statement that would be awesome

Also found this quote as well

USB will work...if you have a 2amp USB.

Just a quick question.

What is the difference of the charger that you proposed earlier at 30 pounds (http://www.ebay.co.uk/itm/Phone-Qi-...-Nexus-4-Nokia-Lumia-920-HTC-8X-/330892988458)

with this at 21 pounds (http://www.ebay.co.uk/itm/Wireless-...S_Cell_Phone_PDA_Chargers&hash=item19db695187)

Both Chinese products with output at 500-700ma.

Why to pay like 33% more?
[Nexus 4 Accessories] vodka_redbull:
I can only comment on the one I purchased (the £30 one) as this thread was created for that product. You will see on this thread that it works very well and is well made with no drawbacks. You will also see in this thread and others on xda developers that many different wireless chargers are available but many of them have drawbacks that are potential deal breakers for buyers here. Examples are very bright LEDs (making them unsuitable for bedside use), hard to find placement of phone to hit the charging sweet spot, very loud beep when starts charging and some will charge to full battery but will then stop charging and won't restart when battery level drops. Let's face it even the LG / Google Orb has problems.

Feel free to save £9 and take the risk but I knew from reading the review posted by the op then the follow up comments from other buyers that I was buying a well made, tried and tested charger that worked very well with the Nexus 4. I just posted my eBay link as it was a cheaper price than the one the op posted but wanted to confirm it was the same product and the seller was excellent.

Good luck with whatever you buy but if you don't buy the Metrans and you have problems then please don't say I didn't warn you.

Thanks
[Nexus 4 Accessories] Khaiyan:
Thanks vodka_redbull for the excellent summary. In short, for the extra £9, you are getting a premium charger that looks and functions very well. I can't say the same for the other model you posted (quick look around the forum will reveal why).

Also to bryanlim, sorry I was unable to reply earlier. I would like to make clear that you can power the charger through a USB connection, I just tried it now and it worked fine. What is the exact problem you are facing?
[Nexus 4 Accessories] bryanlim05:
No Problems. Are you able to plug the cable into a USB port on your computer and the charger will still work? When I have tried plugging it into both my computer USB port and a powered USB hub, the charger blinks red for me.

Going by the specs as other people have pointed out, a normal USB port can only output 5v [MENTION=467413]500[/MENTION]mA up to 1A. So theoretically how would this be able to power the charger when it was stated you need 5V @ 2A for the charger to work?

I know this is a nitpick as I just use the included power adapter and it works great
[Nexus 4 Accessories] rowdybeans:
I ordered the Metrans qi charger and got it today. My phone charged well from around 30% up to 90%, now it seems to be flicking between charging and not charging? Does anyone else have this issue?
[Nexus 4 Accessories] glowsti047:
You sure you're in the sweet spot? Happens to me if I'm slightly off the sweet spot.
[Nexus 4 Accessories] rowdybeans:
I think the phone just tends to move a bit on top due to the slippy back, so it misses the spot.
[Nexus 4 Accessories] Khaiyan:
This is actually a feature of the charger, it stops and starts the charge according to the temperature of the device. The charge stops when the Nexus 4 goes above 40°C and resumes once it cools down. You will see the cycle repeat closer to the 90% battery mark because the phone is much warmer at this point.
[Nexus 4 Accessories] rowdybeans:
That makes sense. Thanks.

I decided to order from A Happy Deal again, after cancelling my original order.

It took around 2 weeks to receive it from the date of initially placing the order.

I asked if they would provide a UK adapter and they surely did. (free of charge)

Can't complain about the service at all.
[Nexus 4 Accessories] VOLTAGEROCK:
I put a screen protector on the back of my Nex and it was the type that needs soapy water to apply. Now, the phone sticks so well to the orb its unbelievable. It actually picks up the orb off of the desk when I try to pull it off! No slipping whatsoever like what happened with no screen protector. Also I thought I wouldn't like the type of protector that requires soap and water but it actually makes it so much easier to apply as aligning it in place is simple just like when people do window tinting. I have a couple tiny bubbles that are barely visible and not worth the trouble of trying to reapply.

I'm also trying to finish a project I started that allows me to use the orb in the car with magnets and the discs that the Palm Pre touchstone back cover uses. I'll post a you tube link when that is complete.

I've bought my Metrans charger in the first week of April from Everbuying.com for $42 including shipping to the Netherlands. Shipping took a bit longer than expected, the charger arrived today. I must say, I'm really impressed with this charger, the sweet spot for charging is pretty big, the light is nice and dim, the peep is not that annoying (allthough I might silence it in the future). The only thing that I did not like was the charger being white. It's not that I don't like white, two of my last four phones were white. However I want black accessories for my black phone..

So after checking the charger worked as advertised I started disassembling it, which is done by removing the four screws underneath the feet of the charger and then just pulling it apart. So in case anybody wondered how the chargers internals look like:

I've painted the front and back of the charger with Plastidip. This is rubber type of paint that is used in the automotive industry to easily paint emblems etc. The main advantage of Plastidip is that it can easily be removed.

So there you have it, a black Metrans qi charger for a black Nexus 4. In case anybody wondering, I'm running Rootbox with Nova Launcher and Mianogen icons. The wallpaper is from Chrome OS and is included in the transparent Holo CM10 theme. The battery widget is called Battery Widget Beta.
