Can someone help to check the Glass charger supported input voltage range?
How would one do that?

Straight from the charger that came with Glass...
INPUT 100-240v ~ 50/60Hz 0.25A
OUTPUT 5V 1A
I'm guessing you're really interested in that the charger puts out 5v 1A into glass. I have a 2A charger that I have tried but didn't have much luck, I haven't tried again, but I think it caused glass to not charge that night.... Maybe it has a limit to how fast it will charge as to not overheat the battery.
Definitely don't try putting 110v at any amperage into Glass... You'll have a nice brick.

OK so like some others i have the strange problem that the charging cable is "falling" from the connector on my note 2.
i have found a solution with replacement cable from HAMA and it was great cause the connector is about 1 mm longer and keep "stuck" inside the not 2
the problem is that i have found out the charging is slow...
i thought its my imagination but i take the charger on my bag to work and yesterday night went to sleep with about 12% battery and connecting to the charger i was sure that in the morning the battery will be full....
i woke up 3.5 hours later to work and ... ooops only 74% battery...
i decided that it has to be the cable so i took with me the original cable and here i am at work connecting the charger and in about few minutes i got 80% battery.
so i guess we have to find a thick cable cause "having" 2A charging is depend also on the cable thickness ...
I had similar problems here : http://forum.xda-developers.com/showthread.php?t=2015459
It looks like all cables are not created equal.
I doubt it was the gauge. It probably was that the pins weren't fully contacting because they weren't aligned right or something. It doesn't take much wire to deliver 10 watts.
I don't have problems with charging, but the cable fit is very loose and can be very easily disconnected. I thought it's just me.
I too have noticed shower charge rate on other chargers/cables. I used one of my old palm pre (yes remember those) chargers and cable to charge my note2 one day and it took forever. Not sure what the reading is buti believe it was a 1.5a charger witha thinner wire.
I am using the stock Samsung note 2 charger/cable my phone came with and it is much faster. On the cable it says 23AWGx2. Not sure what the x2 is but i would look for the same 23 AWG.
I also have an I go charger with the interchangeable tips. I believe it is a 2a charger. Not sure about the wire gauge but it is thicker. It also charges fast like the stock one.
I'm guessing the smaller gauge wire loses some charge through the extra heat it is generating to push the2a required. I did notice on the palm pre charger that it was hot.
I have noticed on all my chargers besides the stock one I have to push much harder to plug it in. I hope its not damaging the connector on the phone.

The important thing is amperes, not watts. And 2A is not that small.
I tried using the following site to calculate the voltage drop : h ttp://genuinedealz.com/voltage-drop.html. And with 4ft of 28AWG cable at 2A, the voltage drop is 1V. And 5V-1V=4V is not enough to completely charge li-ion batteries. Switch to 20AWG and the voltage drop becomes a more reasonable 0.16V.
Also, voltage drop is proportional to length, so longer cables must be thicker to compensate.
Attached is a picture of my BLACK genuine original charger and my WHITE anker E4 charger.
I used both cords through the Anker - the genuine only giving out 800 MAX and the Anker cable 1800MAX
I used both cords through a Kensington Dual charger 2.1a and the genuine only giving out 800 MAX and the Anker 1200 MAX
Im confused as to how the terrible looking white Anker cable is better than the original genuine cable?
I have tried a few cables and NOTHING has compared to this Anker one in terms of ratings (via Galaxy Current App)
Where can i buy another Anker cabe like this to replace all my other cables?
Thanks
Where ever you bought the first one.

Something is wrong with your black original cable cause its acting like a thin wire pc cable. My original Samsung wall charger and cable works at perfect 1.8A just based on under 2hr time it takes to charge oem battery. I suggest monoprice cables in other thread because they have original 24AWG/28AWG thick wires. That's what Anker cable probably has as well. All my cables at home are either from monoprice or Nexus 7 or Note 2, thus rated for 1A-2A current.

Hi, first excuse my poor English
How do you know how much mAh give you each cable?
Thanks in advanced
It's simple, the anker cable is shorter and thicker = less resistance = more mA

Hi, you are true, in two sample of cables of the same material, thick is synonym of less mAh capacity. :good:
Three things:
1st) I recently a make a extensión for a usb charger. I buy a good (thin and expensive) USB to micro USB cable, when i cut both i discover the internal cables of the newest (thinner and expensive) have at least the half diameter of my original (and thick) cable ,
Why look thinner the new one but don´t have more capacity? because the new cable (thinn), is ONLY massive shielded.
2nd) In your first post, you specify precisely two mAh amounts (800 and 1800). Again, please, How do you calculate? or How do you measure?
3rd) Is a fact two cables, made with the same/equal material, deliver differents amount of mAh using the same charger, by the configuration inside of the micro usb conectors. http://www.usbpinout.net/
If I use the cord that comes with Glass, with the plug that goes at a right angle, could I plug Glass in while I'm wearing it, running the cord behind my ear and down my back to a battery pack in my pocket?
It might looks ridiculous, but I'd feel better knowing I had the option...

Yes you can and I actually just bought one to do just this for those long days without being near a charger.

Which pack did you end up buying? I think google recommends using the wall charger that came with the Glass. And that charger charges at .25A. I wonder what the long term effects of charging it at over 1A ? Anyone have any ideas please chime in!
Sorry, I meant that I was ordering Glass! With the new version future-compatible with prescription lenses and the possibility of finessing an external battery pack, my reservations are just muted enough for me to pull the trigger.
I hadn't seen that about the charger. I have an Anker with 3A output. I may have to look into something with fewer amps, I guess?

I was thinking the same thing, if someone manufactures one of the tiny/thin curly cables like some security detail wears it would be a great combination for glass, I'd just keep the usb battery in a jacket pocket, or even on a hip clip...
With a clip for the neck of your shirt, with a micro usb end, and a USB A connector... I'd be all over it!
which one is the best one??
I do this now, I use a xtreme pax by new Trent

The Glass will only charge at the rate that it is capable of charging at. If Glass draws 0.25A when it charges, that's all it will do even if you plug it into something capable of delivering 1 trillion Amps. The charging circuit is in the device, not in the plug you stick in the wall. BTW, same thing with phones/tablets. The important thing is for the plug to be capable of delivering MORE than what the device needs.

Yup.
I have had GREAT results with an Anker 12000 mAh battery pack and a right-angle MicroUSB cable.
3 foot version of this is great for going to a jacket pocket:

Hello guys,
Few weeks ago i read about connecting standard wireless qi usb adapter to phone itself. I mean, connect 2 stripes of cables to 5v and ground on motherboard, so usb would be still avaiable. Do you know where on motherboard those pins are ?

Interesting, I'm trying to find out too. I did a mod that way with my NOTE1. Mostly likely near the USB port, but I afraid it'll affect the NFC , because NFC is on the Cover. And the coil 's pcb must be extremely thin.
I would gladly get rid off nfc anyway, as I don't use it. Voltometer is on its way to me, so any time soon I'll try to update the thread
news pliz??
thanks..
Can wireless charging be used when case is still on the phone?

current Qi is good for 7mm i believe...which is plenty of space for most cases. it wont pass through metal though, and I'm sure some materials hinder that more than others. I used a couple different cases on my nexus 5 and was able to charge with all of them.
The Qi chargers are 12V I believe. I modified a car charger to fit the adapter for the Qi wire. I had to solder it to the 12V wires in the car plug. The 5V would not charge it.
You should be able to find 12V power coming out of the power supply.
Just bought an S6 and want the dock, are the S6 and S5e ones the exact same, so each tab can be used in either?
Yes they're the same.
Charging docks are the same
The charging dock is the same. Basically it is a not quite USB port with a 33K between 5v and D- and only charges at 5V but can go well over 1A (i.e. it won't go to 9v charging).
The keyboard covers are NOT the same (I think one set of magnets is turned around - there is a small set in the charging dock).
How about the Tab S4 dock, is that also the same or is it different?
s4 dock and pogo pins are spaced much further apart, they are not compatible with s5e and s6.

Yup, I measured a max of about 10w at 5v through the dock. Not bad, but I can charge faster with a cord at 18w.
It leaves the USBC interface open
Yes, you can charge at 18W, but not if you are using the USB-C port for a peripheral (I have a Logitech K400+, various connections, a USB hotspot).
The 10W charging is enough to keep the tablet charged when running something off the USB.
