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

i think your wrong with the "all usb chargers are the same"
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
Does anyone have pictures of the internals of the charger for the official Nexus One car dock?
The reason I ask is because I'm thinking of buying the car dock and hiding the charger out of view. The problem is that where I'm wanting to put it, there is not enough room to install a 12v outlet alone, much less the outlet and the charger, so I'm wanting to hard wire it all, but need to know how much room the internals of the charger are going to take up to see if it will fit where I want to put it.
i ran into a similar problem to you. I ended up not bothering to pull apart the 5v regulator as it appeared to be glued together. unless someone was very determined to get it apart you you not find anybody who has. I ended up buying a cigarette lighter socket and sticking it and the regulator in my fusebox out of the way.
if this isn't an option you can you any standard microusb charger cable as long as it is rated for 1 amp. I'm pretty sure all 1 amp chargers have the signal pin shorted to the power pin to indicate to the device they can pull 1 amp as opposed to 500ma. If you get one that can be taken apart that would work for your project.
Best of luck with your install! I've hardwired 4 different gadgets into my car and love how clean and tidy everything is. just one cable dangling in my car is too much. please post pics if you get it tucked away as you want, i'd love to see how it works out!
Sounds like space is at a premium. Another option is to hard wire in a Belkin USB charger which is heaps smaller. Then just run a USB charge cable from it to the car dock. Check out the harness I made up in the center bottom pic to get an appreciation of how small it is. Downside is the Belkin Micro USB only puts out 1A as compared to 2A from the genuine charger. So the car dock may struggle a bit.

I like your setup, I may do something like that myself, but not for the project at hand, but rather just to have a 1amp USB charger for whatever.
Now as for the original project itself, what I'm wanting to do is mount the car dock in my 98 Chevy Blazer right below the review mirror. My Blazer happens to have the Temp. and millage computer readout right above the review mirror mounted to the headliner. There's plenty of places to hook into a switched 12v line in the housing for the millage readout, but as I stated before, it's not enough to house the entire car charger and/or and 12v socket.
I'd prefer to use the original charger that comes with the dock so as to not starve it of power. I'm hoping it's just a small circuit board with wires running to the various connectors. I guess I'll just have to buy it and check it out myself. I don't want anyone to ruin theirs just to satisfy my curiosity, not that I would expect anyone to do that to begin with.
Does anyone know where I could get some microUSB charging cables with the D+ and D- data lines shorted already? (i.e. charging cable only, not for data).
Rather not take apart (Read: Destroy) my microUSB cables I use for data. I have USB wall-warts and USB cigarette lighter adapters which supports drawing 1A from the ports.
Thanks!
Cheers,
Kermee
If your like me and still have plenty of mini usb devices around, you would be best off getting a mini to micro converter off ebay, these already have the pins shorted so my wife and kids can still charge up their stuff and its quite easy to pop on/off the adapter depending on what you want to charge.
There's an easy method to "short" the data pins.
You just need a short USB "leading" (6-12' or 15-30cm extension) cable, a piece of double-sided tape and aluminum foil.
stick the tape to the foil, then cut to the size that can cover both center pins on the jack side of USB leading cable, and plug the microUSB cable, that's it.
You can do the same trick for PSPGo stock USB cable too!
I'm interested in this too. Anyone know of any sites? or at least a microusb to microusb WITH shorted pins adapter?

You have to custom make it.
Do you know of any tutorials on how to do this?
Sorry for the bump but i really want to try this out, can anyone give me more specific instructions? I dont know too much about cable wiring
Buy a USB extender cable, cut the cable in half, connect the red from the plug side to red from the socket side, connect black from the plug side to black from the socket side, leave the white and green from the plug side unconnected (tape over the ends), and twist together the white and green from the socket side. Solder, then electrical tape or heat shrink all the connections. Now plug the cable into any USB charger that provides 700-1000mA, plug your micro-usb cable into the socket end, and plug it into your phone.
Thanks man, i appreciate the help.
Got it working :]
I've decided to make my own cables. Then using red heat-shrink tubing where I made the cut & modification so it would denote it's for "USB charging" only with the data-lines cut ("floating) towards the host and bridged/shorted on the device side.
I was going to make several of these so if there's enough interest, I'm willing to make several extra of these to sell for a nominal price if anyone is interested.
Cheers,
Kermee
I have one of these, for charging only, which I have plugged into my work computer.
Picked it up at some store near where I live, in Hong Kong.
Had no idea it was just for charging (actually, didn't even know you could buy such cables).
I'm probably going to get rid of it though, as I would like the ability to transfer data as well.
You do know that your phone will charge twice as fast with that cable right?

Yep, the charge on the cable at work is really slow! But I'm not too bothered as it just sits there during the day.
Be aware of that, the phone may get hot when charging because more current is allowed to speed up charing.

Yes, it does get a bit hot.
In any case, like I said, I'll probably buy a proper sync cable instead in the next few days.

Just wanted to say thanks for posting up this info (for some reason thank button isn't showing for this thread). Ordered some USB extension cables today, can't wait to try this out. I've long been plagued with not getting enough juice my USB car charger, now I know why.
Edit: BTW, what's the reason for using the USB extender cable for this, couldn't you just cut an existing USB cable in half and short the D+/D- wires? I'm guessing you cut the extender cable so that you can disconnect the intact USB cable and then it would still transmit data if you desired?

You could do that too if you like. I have a big pile of 4" extenders from USB flash drives and wifi dongles and didn't really consider cutting up a microusb cable.

Just to confirm that I'm understanding the shorting of the D+ / D- wires together, the short needs to be on the side of the cable which is connected to the phone, yes?
The D+ / D- wires which are on the side of the cable plugged into the car charger just need to be covered w/ electrical tape and not touching each other when connected back together, yes?
I drew out a sketch based on your outline of what's connected back to what, and that's what I came up with. The shorting of the D+ / D- wires going to the phone must be how the phone realizes that there's not a data connection to be made, so instead will just look for max power? If the D+ / D- lines weren't shorted when connected to the phone (but instead just not connected based on the cable), would the phone just assume USB and charge slower at that point?
Thanks for your help and clarification! I think I'm understanding what you're outlining.

Yes, leave the charger side (USB plug) unconnected and preferrably insulated, and the phone side (USB socket) shorted. Before a USB link is established, both a USB host and USB device will set and check for different voltages on the D+ and D- pins to determine what's at the other end. This is just an extension of that and is safe for the device.

Thanks very much for confirming! I'm going to short two micro USB cables I've got for car use only.
so this isn't specifically related to GSIII, but that's the phone i have an i don't want to fry the thing so figured i'd ask here.
yesterday while at lowes getting a gfc socket for the house i saw they also had replacement plugs you could wire up that had a plug on one side and two usb ports on the other. obviously for charging various devices without having to use the plug portion of your wall charger.
question is... do the chargers have some sort of electronics (or whatever) to prevent overcharging or is all of that junk in the phone itself?
the plug wasn't expensive and was kind of nifty so figured i'd buy and wire it up if it was safe to use with my phone.
thanks!!
I have a USB cable like this where the power strands were split into two to provide more power. This cable was originally from an external USB DVD burner, where the one female end plugs into the burner, and the two male ends plug into the PC.
I was wondering if I could use this same cable to be able to use a Quick Charge 2.0 wall wart while still be able to transfer files from the pc. Basically the female end will plug into the phone, the male data+power end will plug into the pc, and the male power only will plug into the wall wart. My end goal is to only have one cable on my desk to plug into my phone, and not have to go under my desk to switch back and forth between plugging the other end into the PC or plugging it into the wall wart for charging.
I was wondering if someone tried this before and if it does indeed work. Or if it will cause problems, like if the power current from the wall wart would flow into the PC and short something. Any ideas?
Thanks
