They claim to be compatible with the N4
I just ordered one of these Metrans Wireless Chargers
Also available from Dealextreme
Stupidly cheap - it'll probably take a few weeks to get here but I'll let you know if it's any good when it arrives

Good find! I've just ordered one from DX. If it works as expected I'll probably get another at this price - one for my desk at work and one for my bedside table.
Tiddly little wireless charger - less than £15!

It cost me £14.04 included "free" shipping from Hong Kong.
I am very pleased with it. So far, this is the only wireless charger that has been able to charge the battery through my rubber case and stuck to it metal plate used for magnetic holder.

First impressions? It's tiny! Very neat, feels solid. Came with a nice (white?) usb/micro-usb cable.
Will test it out this evening and report back
Anyone know if there's any way to switch wireless charging off and on from the phone side? Google seems quiet on the subject
Actually, I guess it's pretty much an electromagnetic process between the charger coil and the phone's coil, so it may not be turn off- & on-able.
The slight problem with these things is (I've read) that they charge to (or near) capacity then stop charging, so by morning your phone may have discharged by 5-10%.
My fix for this was to have Tasker turn wireless charging on at 3am (or so) then by 6 my phone would be at 100% in time to get up & go, without losing any power, as it would if I set it to charge from 11pm (reaching max c. 2am then discharging til 6). But that won't work if the phone can't turn charging off & on.
New, less elegant fix is to use a timer plug to turn the mains AC to the charger on at 3 am or so.
Again, I'll report back

Qi wireless charger should charge to 100% then switch off and come back on again around 96% keeping the phone in the 96-100% range forever.
If you see it get to 100% then switch off and never turn back on again then it's most likely because you are plugging it into a 5v 1A mains charger, try it with a mains charger that can produce 2A and it'll work properly. The stardard N4 charger is only 1A and is known to have problems with this device.

Was following that thread but took my eye off the ball!
Have ordered a 2A USB charger from Amazon.
Let's see what they deliver
With the 1A chargers I have, charging seems a bit slow unless the phone is powered off.
When this is done, it charges really quick (and keeps its charge til morning as Stuart_f points out) - it's just a PITA to have to shut down and boot up.
With the case on and phone on the phone registers as charging, but the battery level doesn't increase. Presumably there's not enough power going to it - using a 2A charger should make the difference, but again I'll report back.
Once more - I can't get over how tiny this thing is - 6cm in diameter by 1.2cm tall! That's roccoculous!
The LED is a bit on the bright side but a bit of insulation tape has sorted that
I really need to learn to RTFM, or at least what it says on the side of the box:
Not surprising that it's been a bit dicky with only 1A going to it. Reassuring that a bunch of other people made the same mistake
Also I found that it charges more reliably (quickly?) since I reverted to stock 4.3 kernel (previously on franco kernel v 174)

You need Ultimate Sound Control http://forum.xda-dev...d.php?t=2482155
Really handy - allows you to turn each system sounds on /off. Pro version (free for a few days at the above linky) also lets you change the sounds, to play different noises without the need to switch files with a file explorer each time you update.
Bloody quiet in here at the moment, ennitt?

Some of us are reading with interest, even if we're not messing up the thread with useless thanks.
But thanks for all the research, I hope to be making use of it soon!
I think the main reason the N4 forum is quiet is that the stock phone is just so darn good there's no real need to mess with it. A big contrast to my (much-loved) ZTE Blade, where I was constantly trying something new. :-)
A cheap and reliable wireless charger would be most welcome, however.

Hi thriddle - good to hear someone's finding this helpful!
There really is virtually nothing non-obvious to choose between these wireless chargers - they all work in the same way, so the problems appearing with the cheap as chips pucks (eg setting up wakelocks etc) are just as likely to show up with the fancy Google Orb. Potentially the orb might be a bit more efficient so you might not need a 2A charger (though I'm not sure on this) but really if you get a super cheap device with a 2A charger (total cost, about six quid if you shop around) you'll be golden.
Of course, you'll still have the wakelocks to content with, but there are workarounds for that.
Interesting to note that the N5 appears to have 4 little magnets around the wireless charging coil, whose purpose is assumed to be to connect to 4 magnets on a charger to ensure the coils line up niceley for optimal charging. Apparently some old Blackberry device had a similar set up.
