My charger that came with the SGS4G is not an official Samsung one. This is because I bought my phone used and it came with a 3rd party charger.
The charger is just a one-piece charger. I cannot remove the cable. It says:
AC Charger
Model: Micro USB
INPUT: AC 90V-240V
OUTPUT: DC 4V-8V
Can I use this charger with other phones that charge over MicroUSB? Do I need to make sure the other phone can handle 4V-8V?
Also I intend to buy another charger as backup, but I have this adapter which I plug in my USB cable into and then it goes to the power outlet. When I used this, my phone acted very erratic, swipes would not register correctly, phone became unstable, etc. Any reason for why this would happen?
It's sounds like your generic USB charger, and should charge anything that would charge if you were to plug it into a computer's usb port. I have a belkin usb plug, except it has a usb port on it instead of a cable, and it charges everything, even PS3 controllers lol.
Who makes this charger? If it's a super cheapo, the power may be dirty and may cause your phone to act funny.

It is some cheap USB to AC charger I got from Dealextreme. Never had a problem with my old Huawei U8100 or DSLite.

Yes and yes to the first two questions but it normally isn't a problem depending on what is charging.
To the third, I had that same problem with my ZuneHD and a generic manufacturer's cable and I still don't know why.

The major issue is "are the data lines shorted together?". If they are not, your phone (and other devices that use USB for power) will see it as a simple USB port and limit draw to what a PC USB port can supply (not much).
There are also some ways (particular resistors used across... pins 1 and 3?) to indicate how high the charger can go.
Most of the USB car chargers (at least the ones with USB ports) do NOT do this, so they take forever to charge a phone.
Easiest way to tell: with the charger charging, go into device settings. If it says "Charging(AC)" you're good; "Charging(USB)" not so good.

I ordered my Nexus One without a charger and was wondering if I could just use my iPhone USB charger with the supplied USB lead?
I'm guessing that's all the charger is right? Just a charger with a USB port or a miniUSB charger?
all nexus one orders come with a charger. They also come with a usb cable, back-slip carrying case, and a headset.
Not when you want it shipped to the UK.
It adds a charger to the basket so I just deleted it
If it is in the box I'm guessing I will still get the US charger and can just use an adaptor to use in the UK..
Actually I have used the apple iphone charger with usb cables to charge a BlackBerry 8900 and a G1. I would guess it would work for this, but its your phone and your money if you burn it out
yeah youll get a US charger then. In any case all USB chargers are the same. if you have any USB charger with a USB port, you can jsut connect your included USB cable to the charger.

this has micro usb i believe and the charger's you are talking about are all mini-usb. not compatible.
this is not true. the side that connects to the charger itself is still all regular USB. both mini and micro USB cables have the same pinout and electrical output standard.
i know. i'm saying that the end of the cable that plugs into his G1 will NOT FIT into the nexus one because it's MINI USB and the nexus one is MICRO USB.
thats not wat hes asking. hes asking if an iphone wall charger (which simply has a standard USB port on the other end) will work.
Ohhhhhhhhhhhhhh sorry

my usb charger (micro usb) for my bluetooth headset will not charge a cliq, it its the same in appearance, but somehow it is actually different
however, the charging cable i had when i had a cliq charged my bluetooth, but I avoided it because it was obvious the 2 chargers where different.

correct. Certain chargers have different amp ratings. For example, GPS chargers generally require higher amount of amperage than cell phones, and certainly a lot more than bluetooth headsets
the g1 charger will not work with the nexus one. I have both phones. The behold II charger will work with a nexus one phone. my gf had the behold ii phone.

You mean plug-wise it won't work right? Because I just took my USB charger, took a Mini-USB to Micro-USB converter and used the G1 charger to charge the N1 and it works.
I'm not sure about the Nexus One but I know on the N900 you could have the problem of that charger not supporting the Data pins(D+ & D-) to communicate with the device and establish a power draw rate, in which case the charger won't work with the phone. The solution was either clipping the data lines in the USB cable, or shorting out the pins in the charger. I doubt the Nexus will be that picky about chargers though.
Usb Charger
Hi,
I just have ordered mine from US. I am from Europe and i will definitely have the problem with the originally supplied charger.
As i am aware all usb ports works with the same voltage - 5V., only amp rate is different. We just need the output amp rate of the original charger and have to be careful not to exceed it. The smaller amp rates are OK (just the charging time will be more.
For example in the originaly stated data from Google says:
"Power and battery
Removable 1400 mAH battery
Charges at 480mA from USB, at 980mA from supplied charger"
Just one to confirm is the original charger amp rate 980mA as Google stated?
I think you'd better to buy a new mobile phone charger for your nexus one for safety.
Just tested plugging the N1 in directly to computer using a miniusb cable w/ microusb adapter and works perfectly. It detected the phone and did that Mount SD notification. I mounted, transfered couple GB of files w/ no interruptions. Also, it charges it like normal.
Usb standard is 5V, most chargers with usb output should be 5V. The Amp is determined by the Voltage and (electrical)resistantce, check Ohm's law.
However the chargers are probably limited to a certain amperage(max amp output). All chargers I've seen have inscripted input and output values, as long as output values are within usb standards it should be ok.
I have an iphone car charger with usb out. It stays in the car and charges my family's gadgets no mather the manufacturer/type of device, as long as it supports usb charging.
So theoreticaly it should work. To be safe check the output values on the usb charger.
If n1 came with the american charger you can check the output values of that against the iphone charger output values.
Would a simple US 2-pin to UK 3-pin plug adaptor be fine?
The few gadgets I've got with US plugs I would just buy a UK version plug but since you cant just buy these in any shops (yet) will just have to wait and see what they supply first.
Anyone here with the US charger could you post the output values please
As the cable is too short, I attached an extension cable.
However, now it does not charge. If i connect the short cable that came with the Transformer, it charges fine. Any suggestion?
The TF101 "short cable" as you call it, is a USB3 cable, what has +5 pins inside. One of these pins control the 15V charging (the tablet takes 15V from the charger instead of the usual 5V USB), if it can not send the signal through, it won't charge. You need a USB3 extension cable what's pretty expensive though.
Get this one or a similar one. As you can see, 2 reviewers vouch that this cable works.

Got on of this USB 3 cable while at HK and work without any problem.
Thank you guys. Will be purchasing one. I am guessing Belkin F7C008QAF Conserve Valet USB Charging Station - Energy Saving wont be working with this :/
That is correct, because the transformer looks for termination of one of the usb 3 pins, if you plug it into a usb 2.0 or lower extension/hub it just wont work. You must have a usb 3 extension/hub, or, there are many DIY chargers that are probably cheaper than a usb 3 extension cable and definately cheaper than a usb 3 hub.
Even a usb 3.0 hub or charging station will not charge it. Usb does not provide the voltage required. Only the outlet adapter will work

I am going for a trip, and I want to reduce the number of things I carry with me, and I was wondering if I can use the Asus TF101 charger to charge other devices that plug to usb, like my mobile phone.
I know that the TF101 charger gives more power than normal chargers through the USB3 cable (Required by the device, otherwise it will not charge), but if I plug a usb2 cable and plug my phone, will it charge or fry it?
I wouldn't use the charger, I'd use a usb port on the dock, personally. I'm just paranoid though, it should be fine since the limit on 2.0 is 5v

I don't have the dock , that's why I am asking
Yes, I do that all the time to reduce the number of charging bricks I carry. If Asus only had the foresight to make it a dual port!
There is a DIY charger thread that also has lots of information about how the charger works. If I recall correctly, it puts out standard 5V normally. When the TF cable is plugged in, it actually shorts out certain pins in the USB 3.0 plug and that signals the power brick to kick up the voltage to 1.21 gigawatts that are needed to charge the TF. A standard USB 2.0 plug won't be able to short out the pins so the voltage will stay at 5V.

I was planning on using my iPad charger to charge my phone, iPad, and TF700 while on the road. It puts out more than enough current at +5 volts but doesn't work with the TF700. The Asus charger outputs +15 and +5 and works with the Asus cable and an OEM cable, and also works charging my phone using a micro-B cable. Is the TF700 charged using +15 volts?
The TF700 booklet says it can be charged from a USB port, which is +5 volts. While that may be an impossible task on a PC, it still means that the TF700 can be charged using a USB cable and +5 volt charger. Why doesn't it work? Has anyone gotten a 2A +5V OEM charger to work with the TF700? Is there a pinout diagram for the Asus cable and charger anywhere? Thanks.
Not sure if this helps, but the keyboard dock (unlike the tablet itself) can only be charged from the charger, not usb, so it must draw more power than a standard usb.
It's also possible your Apple charger usb port is pinned to only work with "apple approved" products? Have you been able to charge other devices from it?

I don't have a dock nor am I trying to charge the TF700 from a PC USB port. The Apple charger puts out +5 volts to anything plugged into to it and the TF700 apparently "knows" when the Apple charger is connected to it because it turns on if it's off.

It will charge VERY SLOWLY on 5v USB while turned off. Will not charge via 5v USB while on. The TF700 requires at least 12V/2A to charge while on. 15V/1.2A is what's recommended by Asus (based on their proprietary charger specs).

You are correct. With the TF700 turned off, an hour of charging with the 2A Apple charger had increased the battery level from 29% to 34%. I expect the TF700 to be fully charged in only 14 hours!
Thanks.
Have you considered a power inverter? I use this one with my A100 though I use a FM transmitter to charge my phone.
Somewhat related to this: in the past, when using devices that have a power block with a USB port and a charge/sync cable, such as an iPod or even my Galaxy Nexus, I've used a USB extension cable to give me a little extra slack. For some reason, that doesn't seem to work with the Infinity. I've tried three different USB extension cables and the tablet never shows that it's charging. Is there a certain USB cable I can use for this?

Are you using a USB 2.0 or 3.0 extension cable? It's my understanding that the Infinity uses USB 3.0.
You need 15v to charge the Pad (I kept thinking 11, but the adapter says 5V or 15V output). This makes sense since there are more pins. Standard USB has 5v rails (ther are 4 pins, I 5v power, Data+, Data-, ground). Since our chargers are 40 pins, my assumption is that there are more pins dedicated to charging and multiple pins dedicated to data (possibly a few that are dedicated and some that are for whatever data is being passed through (assumption)). If the adapter is outputting 11v then it can send more power through the cord and multiple pins can push electricity through. When you are only pulling 5v (i.e. most AC->USB transformers) you will need a lot more time to charge, hence the trickle effect (and don't turn on the screen!)
It can be charged with 5v if the tablet is off.
There is a jumper in the USB cable itself that kicks the Asus charger into 15v mode so it doesnt accidentally fry your devices if you plug in, say, your cell phone to charge for a bit.
To make a custom cable just throw 15v across three pins in the connector (5v each). You can find all the info here: http://forum.xda-developers.com/showthread.php?t=1633747
Yes, i know its for the prime, the connector is exactly the same, the pinouts SHOULD be identical.
DIY approach?
I've got a TF700T and a TF201 dock and a misplaced charger. I ran into the same trouble that a lot of people here did ....... generic chargers not working, USB on my computer only trickle charges the tablet, nothing for the dock, etc.......
After much poking around I learned that both require 12 volts to charge. That said I dug thru my junk and found a 2.2a 12v DC wallwart. I hacked apart a USB extension cable for it's female end, broke out my breadboard and put together a 12v USB connector... that after several days of charging and draining.... charging and draining .... works like a champ.
So to be a bit more specific, pin 1 that's normally 5+ volts I'm supplying 12+. Pin 4 is ground same as always and that's it. If you wish let me know I can probably throw up a little illustration or something.
Since I did that I've refined the whole thing a bit, cleaned it up, wired everything directly and heat shrinked the whole assembly.
It will charge both together or either one by itself in just hours EVEN while using them..... heavily. No overheating, no troubles.

I think the cable type might only matter after the ics.30 update when I was on the ics.26 I could use a standard extention cable, I had my device plugged in when I updated and my device stopped charging, and I freaked out thinking I broke something. But after finally removing the extention my tablet would charge. I have not tried to use the extention cable since so I don't know if it works with jb.

The Asus charger switches its output to 15V from 5V when a USB3 plug is detected. If you need an extesion cable to charge the Transformer, you'll have to use USB3 extension cable. If you want to use this charger on other devices, be sure to use a USB2 cable to not to fry it with 15V.

Thanks for the warning - I hope there are no cables with USB3 and micro-USB2 plugs though.
Awhile ago, I'd connected a USB extension cable to the charger that came in the box, and then to the cable that came into the box. In otherwords: Power>charger>USB Extension>Charging Cable. I've always gotten this message about my phone being able to charge faster if connected to a different charger because of it. I'm assuming it's because of the USB 2.0 Extension cable, which was a cheap one I'd gotten off monoprice. It still charges, slowly but surely. I do not use Fast Charging, because I have a ZeroLemon battery which does not support it.
Would I be able to just get a different USB extension cable to fix my charging issue and if so, can someone explain what type of extension cable to look for? Or, are there longer charging cables that support fast charging (should I swap out my battery for the stock one)?
I think the problem maybe due to the fact that you are using a USB extension cable to charge your device. I would try getting a longer USB cable to charge your device instead. From what I understand it doesn't matter what brand of USB cable you use to charge your device as long as it's manufactured properly.

I have an old extension cable (5+ years old) and everything works fine. I don't use it unless I'm traveling though.
Point is, it isn't because you are using an extension cable, but because of the extension cable being used.
Look for an extension cable that is thick. Don't buy anything with a very thin cable. They're usually made very cheaply. Also make sure that it isn't only a data cable, but either a charging cable or data + charging. I'm not really sure if this matters, but it may affect things.
Hint: an extension cable made for a Playstation 3 will work perfectly.
