I bought two of these to use with my existing usb cables and wall chargers. It works great for both charging and file transfering.

there is no "right" output
most usb ports will charge up to 500mA
the stock usb wall charger is, i think 750mA, i havent looked at it in awhile since its behind my desk, but i know its not 1A
the oem nexus one wall charger (non usb) will charge up to 1A
I would only recommend a 1A charger because there's no point to use a lower amperage, it just takes that much longer to charge your phone.
Couple of good threads on this topic, both on the vibrant and the i9000 acessories thread. Lots of good info. The deal extreme chargers look promising. Waiting to hear from a person who bought a 2amp charger if the extra 1a is used by the phone especially when using gps.

well, my phone will still charge (slowly) while watching avatar, which i would assume is a pretty high load on the cpu, using the 1amp charger i got from dealextreme.
fwiw, the one i have is a 1A "HTC" wall charger thats square and lights up HTC when charging, it ****s up my screen sensitivity so i wouldnt recommend it, but it was only like four dollars so i'll live with it.

AC charger or car charger?
The charger does not dictate the amount of current given to the phone. The phone will only draw what it wants to. The charger can limit the maximum current but if the phone only asks for 700mA, a 2A charger will only provide the 700mA demanded by the phone.
I don't know what the max current our phones will use but having a larger charger will only help if the phone requests the larger current.

I'm not sure how stressful watching Avatar is from a current draw perspective. The torture test is to turn on 3G, Bluetooth, synch, GPS and run the Navigation app while driving. Some post indicate that only a true 2A charger will be able to do this w/o discharging the battery. 1A ones can only limit the discharge. Cheap ones empty quickly.
Could you check what your charge current file value is for your 1A DE charger? Make sure to use the original Samsung cable and cross check with the original Samsung charger and a USB port.
1) Use an application like ES File Manager or Astro Filemanager
2) /sys/class/power_supply/battery/batt_chg_current

well, i'll come back and update with samsung usb numbers as i wont have access to it for awhile.
i checked the file when using the HTC cable plugged into my work dell and it said 850-860 after checking a a dozen times
plugged into the wall charger now and its around 700-750
is that supposed to be reporting in mA?

Yes, but I haven't heard that anyone has measured it. The numbers you are getting are consistent with what others have see. 800-900 for USB. The original Samsung 700mA charger is getting 900-1100.
If you have another Android phone try that one as well to see the differences (e.g. G1 ~300-400).

Any car chargers that anyone could point me to that charges as fast as a wall charger?
As it is right now, unless I have my screen off and no apps running it drains faster than the charger can put juice into it...
I'm just using an el-cheap-o aftermarket car charger.
Thanks!

What I use is a cig to usb plug (cost me 10 bucks at walmart). Then I bring the cord from home that came with my phone and plug that into the USB to cig thingy. Works like a charm, I haven't noticed it charging slower than when at home.

i bought one from t-mobile... its about $29 but its worth the price. I get charge speeds btw 850ma and 950ma when on idle
i have the oem cig to usb charger from Samsung i purchased it at best buy with a gift card lol, when i first got my galaxy tablet.
Just get any standard microusb charger rated at 1a (or 1000mAh ). I'm betting your elcheapo is .5a (500mAh).

our device requires an official samsung charger to charge at full ac speed. there was an article on the xda front page last week about how to mod your charger to be recognized as official.

All I know is that now I can run my GPS with the screen on and still move UP in battery - before it would drain faster than the car charger would charge, so, I'm happy with what I have now.
Actually the problem is that some of the car chargers are not at 1amp output but less .75 or .85. Thats why your not really seeing an increase. The stock charger is at 1amp. I know AllGamer likes to use the Blackberry ones (which i believe are 1.5amps) Correct me if im wrong AllGamer.
So just look for 1 amp car chargers the cable doesnt matter itll hold whatever you attach it to.
So, no matter wht brand charger you have as long as you connect the two middle pins you will get full charge as long as the charger can put out 1000ma?
I really need a good charger for the car, right now i use a blackberry charger at work an it charges pretty fast. But i need to know how do i find the currect charge rate of a charger. Is there an app for that?

I need a great car charger and really dont want to spend to much money on it. Furthermore, if I am getting a 1+amp charger, as long as i am using the stock samsung charging cable then it shouldnt matter if the charger itself has D- and D+ shorted right?
Im assuming this is something standard on all usb CHARGING cables as appose to data cables.?

You want a good reliable charger at eBay pricing..... spend the money 1 time and be done with it. You could've already gotten the T-Mobile one and been done with it.

For those of you buying the USB 12V Cigarette adapters read this.
Basically if you use a data sync cord with one of those adapters, unless it shorts the 2 data pins together internally (probably not) the phone is going to think it's plugged into a computer and only charge at 500ma (max output for a computer USB port). The write up above explains to short the 2 data cables together (this is done internally with the main AC charger head) back towards the phone so it will charge at 1amp instead of 500ma.
You can buy this cable and just modify it as described. I bought this USB adapter so I could charge 2 things at once.
Let me get this clear.
All i need to look for when it is charging is AC mode. As long as it says that, it doesnt matter what i have or have not done to the cables, AC mode is AC mode.
The charger i am looking at getting is 2.1 amp (because it has a spare usb port...so 1amp per line) and when i plug it in and it says AC MODE then its good to go right.
I just bought a TMOBILE offical charger that shows AC MODE, so when it MONOPRICE charger arrives i can compare. If it doesnt work its another 5 bucks, if it does i can take the tmo one back.
But again i am just wondering are there any caveats to AC MODE, or is it that once AC mode shows that is all that matters.
Is it better to use the stock charger cord or another cord im just wonder will it make a difference?

If you are talking about strictly the usb cable itself then I'd say it doesn't matter. I use an HTC, Samsung, LG cable and they all work the same. If you are talking about the actual AC adapter make sure it's the right mA.

Could be the quality of the usb cable that you are using. Any well made cable should charge as fast as the stock one. Cheaply made ones may not. And price does not dictate what I mean by cheaply made, I have purchased some of the amazon basics cables and have been very happy with them.

No. The cables won't make a difference between one or the other.
Only the adapter matters in how fast your phone gets charged. I personally used cables that I had purchased from monoprice because the original one got bent and I don't notice any difference in charge speed.
I heard that some people have trouble with samsung usb cables not being reliable when using it for odin.
Sent from my SGH-T989 using xda premium
that's a new 1...
Whered u get that info?
All (well made) USB cables are made for specific standards, all that's special is the nice rubber coating on the wires, & the plastic caps all that really makes a difference is the charger
@above again: unreliablr for odin would also be unreliable for data transfer, or any sort of communication with device, and would either signify a slow ass pc with usb 1.0, or ****ty usb cable...
Actually ****ty cable does affect charge rate. the charger itself is the key components and you might notice the difference, but when i plug it into my cars deck, the stock actually charges my phone and it gains charge even when used..however when i used a ****ty one, it would only sustain and even lose charge when used. In fact, when my phone was completely dead my stock was able to have it power on when connected, but with the **** cable i had to wait a good 5-10 mins before turning it on.
However, using the wall outlet will probably show only a small difference, but it really does matter. although using any of the brand cables moto, sammy, htc, you should be safe. Just be weary of generics. Oh and monoprice cable are good except the head... Well for me the gold plated one, the 2 little prongs that stick up... Wouldn't go up anymore so it doesn't really stick into my phone anymore.

If you look closely the PLUG has different amp ratings. The Galaxy Tab 10.1 plug is 2 amp, SGS 2 stock charger I think is 1 amp.. old blackberry chargers are 500mA or .5 amp.. its been my personal experience that higher amp chargers work more quickly. I use all Tab 10.1 chargers and see minimal difference with different cable.
Sent from my SGH-T989 using XDA Premium HD app
The current rating of the adapter (the mA rating) is the maximum that adapter will output. Similarly, the current rating of your battery/device is the maximum that your device will input. So you do NOT need to match ratings; your device will only ask for as much as it can take. If you have a 50mA rated adapter but your device is capable of 100mA, it will only charge as if it were rated at 50mA because that's as much as the charger can provide. Similarly, if you have a 500mA rated charger but your device is only rated at 100mA, it will only ask for 100mA and there's no chance of frying your device or anything to that effect.
Just got my Galaxy Nexus and everything is rosey and wonderful (simply using stock jelly bean for now), until suddenly i see that I can't even use 3g internet for long periods - *even with it being charged by my macbook air*!!.......
Do some kind fellow XDAers have any suggestions for how I can improve the situation?
Are there some cables that are better than others for charging - maybe a shorter one rather than longer, one with extra pins in it or something, specific brand? Is it that the macbook air isn't high wattage enough of a computer to reliably supply a battery-sucking HSPA chip in the nexus???
My MBA itself was ALSO plugged in at the power and it was in full power mode afaik. also it's windows bootcamp on the mba, don't know if that makes a difference.
Anyway Is there a specific USB charger that would be recommended? some high grade one to guarantee best charging power?
But I can't always be at a wall charger when doing a bit hspa session on my phone. it might be the train. and the laptop is the only power source with which to keep the juice up. (well try anyway :/)
I'll be upgrading to the retina macbook pro anyway soon, maybe that will improve things?
is there some windows app that allows you to regulate usb port power and keep it at a constant high level? (if this is even scientifically correct the way I'm describing things).....
Thanks
USB charging is fairly weak and slow. Some custom Roms have a fast charge option, not sure how much it would help though. You'll have to let someone else chime in who has more knowledge on the fast charge option.

I don't think there is enough power from the air to power your phone enough. You could try installing a kernel with fast USB charging like trinity.

Its likely that the ports on you air aren't able to put out enough power to actually charge the phone. I have an air as well and my phone charges VERY slowly when connected to it.
I would recommend buying a longer usb to micro usb cable.
I got a 6ft one from www.monoprice.com. Good price and solid quality.

Won't do any good if he needs the air to charge in certain situations. I agree that the MacBook just isn't able to push enough to keep up.
Sent from my Galaxy Nexus using xda premium
fast charge option with kernel is best idea as mentioned above
Try to use AC Charger instead of USB. That's the root cause. The maximum power of USB is only 500mA, but the minimum of AC Charger is 1000mA.
BTW, that's not the HSPA's fault. When I play games on GNex which means the screen keep on, the USB charging can't catch up with it. You can see the lossing of power, 5%, 4%, 3%, 2%, 1% and .....
I have this problem also. USB charging takes a hell lot of time and hence I use the wall charger to charge it
Sent from my Galaxy Nexus using xda app-developers app
USB 2.0 puts out a maximum of 500mA, with line loss etc it'll be more like 400. That's barely enough to charge the phone if you're using it. Charge it off the wall with a 1A or 2A charger.
That being said, my late 2008 MacBook Pro 13" charges my GNex just fine off of USB.
The latest model MacBook Airs and Pros will help a little because they have USB 3.0, which charges at 750mA (or thereabouts). Still, if you want a fast charge just use the included 1A charger or buy a 2A charger online.
This is normal, USB only charges at 500 mA, ac charges at 1000 mA. so its possible to pull more than it can charge. Use a kernel and enable USB fast charge and it will use ac mode on USB, but only if your USB connection can output higher than 500. So be careful.

Make sure it's the correct voltage and amperage. The oem charger spits out something like 1.3A. A lot of usb phone chargers output less than 1a

As does the S3 and N7 Gen1.
So long as it's 1A or greater it'll work at about the same charge rate (1A = slower, and anything over 1.35A won't charge much faster).

It didn't work on a charger I had that had a "special" cable that only provided power and ground. When I used a normal USB cable, it worked fine, so it apparently wan't to see something more than just an open connection on the data lines before it will charge.
Its worked on any charger I threw at it including the iPad charger with a HTC cable. Wireless charging also works great with the Nokia one.

Anyone tried using the Apple 12W 2.4 apm charger?
Is it ok to use more powerful charger than the one it ships with?
More capacity charger won't be a "problem" as the device determines how much power to pull. Lesser capacity charges can sometimes overheat if not designed well.
Often devices capable of charging faster will only go into that mode if they detect the charger is capable of doing so. Since the way they determine this is not standardized, sometime high capacity charger charge slowly. This could be caused by something on the charger side, or even the cable being used.
Worse case of using a higher capacity charger is it won't charge at all, but that is pretty rare. Often it will charge, either at a slow or fast rate.
