Get the charger at the link below
http://www.amazon.com/Motorola-Vehi...Q9CA/ref=sr_1_1?ie=UTF8&qid=1334801727&sr=8-1
I got this to replace a cheapo one i had when i had my Droid X. With the old charger, I couldnt keep the screen on and use GPS and listen to music at the same time without the battery losing power. Basically the old charger acted like a battery extender lol.
This new charger charged my phone at least 3-4x faster...even while doing all the things listed above...WELL worth it

I have that exact same car charger. Just make sure that you get it from a reputable dealer... I got mine from one of the parties for a few bucks cheaper and they sent me counterfeits. I had to contact Amazon where Amazon gave me my money back and also sent out two OEM from an Amazon warehouse with free expedited shipping!

Quite a few of the cheaper car chargers simply do not have a point soldered on their boards, causing the phone to think it's charging from a 500mA USB port (like you'd find on a computer) and not go above that even if the charger does 1A/port.
I know even the belkin one has a forum topic somewhere regarding modifying it so that it'll always get detected as an AC power. I believe custom ROM's and kernels has a Fast Charge feature that can fix this too (ie force the device to detect the power as AC), I think.

I use the Motorola charger as well, and it works just fine... I had two lying around, one came with my Milestone and the other came with my Milestone Car Dock that I've bought separately...

Interesting, this is the model I had and I ALWAYS felt like my battery was draining while using the GPS+Music combo. Not a lot, a few percent over a couple hours, but it's not charging it or atleast keeping its current charge. I want the official Sammy card dock. SOMEONE JUST TAKE MY MONEY.

I believe you will be disappointed...
First, this Motorola charger is good up to 2A, while the original Galaxy Nexus Wall Charger is good up to 1A, and Galaxy Nexus recognizes it as AC Charging, meaning that phone is draining as much current to charge as it can...
Second, I do not believe that those pogo pins are good to move 1A, and I could bet the farm (if I had one ) that it won't go over 1A for sure, so, I do not believe that the official car dock will allow more current than what this Motorola charger is already providing...
But, anyway, I doubt that charger is the one to blame, and I will tell you why... Battery is rated 6.8W/h and it usually allows up to 4 hours of screen on time... So, quick math, phone in use, screen on, is draining 1,7W/h and USB charging (500mA x 5V) gives you 2,5W/h, AC charging gives you 5W/h....
Lets say that you get up to 3 hours screen time with GPS on... It still is 2,27W/h... Below 2,5W/h USB charging limit...
So what is going on? Probably battery is too hot charging and being discharged at the same time (and probably the phone is not able to use the battery like a no-break and get its power from USB, so, phone is getting juice from battery and battery from charger) and phone will stop charging to avoid battery damage/explosion due to high temperatures, and also, battery efficiency is lower when battery is hot (it will drain faster)...
My guess is that if phone is still draining with a charger, in this case, check if it is too hot, and if it is, try to move it so it is cooled by car A/C / vent... At least, with milestone, it helps a lot, since I still own my Milestone and its gps is leaps and bounds better than Galaxy Nexus GPS, I've never really used Galaxy Nexus to navigate (yes, my Milestone turned into a dedicated Google Maps GPS )

its very easy to mod any usb charger to turn it into a AC charger. what you need to do is connect the two data pins.

just connect pins 2 and 3 by solder, i've done this on a few car chargers and it works great always shows AC. i didnt modify the usb wire itself but opened up the charger and connect the solder points connected to the data lines, not sure if you can just mod the usb wire. i have 600mah car charger that i did this to, before it wasnt enough to charge the phone with google maps running now it can charge it very slowly.

Just a update,
i purchased the motorola charger and been working great for nearly a month till this couples of days.
the only way that charge is by holding and pushing up the micro port wile inserted in the phone.
i noticed that the charger micro plug does have clips on only one side ,the other side is flat.
does that mean is not a original charger???
thanx

I'm currently using this cables

generally can be had for about 3 bucks shipped. works fantastic - the phone reports as being plugged in and charges accordingly.

Costco charger works
I bought my vibrant at Costco and it came with some accessories, tested the car charger, it works.
Buy a cigarette USB adapter. Buy a micro USB Galaxy S cable. Connect the two. That way it works AND is more versatile than just being stuck for that specific phone/purpose.
I bought a Griffin dual USB adapter and a cable from amazon. Both were ~15. The Griffin has 2 USB ports so I can use the other for something else. Even if both are plugged in, it still charges the phone, even under intense GPS usage.

It shouldn't. The hack is a HW one that shorts the data pins so the cable looks like a charging cable the current goes from 400 mA to 600 mA. Well within the supported range. The phone limits the current to ~600mA.

Agreed. The only reason there is a limit of 400mA is so you don't draw too much power from your USB and harm your computer. If you use a wall charger, it would charge at the full 600mA & all this is doing is making it so it doesn't get registered as a PC USB device.
bought a $6 one from frys but while it would charge the phones temp. would go up by 30 degrees and became super hot to the touch, needless to say I never used it again. It works great on my sons Ipod Touch though.

Status: Dedicated charger, not USB device, which is good because...
Widget reading: 1100mah
Basically we need any 1amp charger that is detected as a charger (rather than a USB device) and our phones will pull its max charge of about 1100mah (according to the widget)
If you already have a charger that is detected as a USB device, you can short the data pins (2 middle contacts, use a tiny piece of foil if you want =D) in your USB cable and it will then be detected as a charging device and pull the 1100mah.
I would love it if we could compile a list of chargers (wall chargers, car chargers, and USB chargers) that are detected as car chargers out-of-the-box.

ah too bad, if the thing opens up easily, it might be fairly easy to connect the data pins (inside two pins of the 4 pins in the usb connect) and "convert it" to a dedicated charger.
Baught some cheap charger off ebay for like 5 bucks, made in china, looks like it should cost about 25 cents to make, doesn't work. Charges for 2 mins, then stops charging, then starts again, then stops, then starts then stops, just loops.
Used the costco charger, came with the phone, works good so far. But phone gets warm charging.
Also have a 40 dollar charger, works the best, no problems with it.
Posted this in another thread but this might be more appropriate:
Just use this charger by Samsung it is compatible with all Galaxy S phones according to Samsung and it is cheap $6.69! The widget shows and output of 1095 and these chargers support the Samsung rapid charging. Doesn't trigger the USB connection.

Also I found that some of the micro sd data cables will not mount.
Here is a compatible Samsung Branded micro sd data cable that does work with Mac OS and Windows $2.35!

USB Charger - Upgrade Mod for SGS Phones.

more/better/other info in this thread. http://forum.xda-developers.com/showthread.php?t=1384253
This post will show you how to MOD an un-official Samsung USB wall charger into one that will enable full speed charging on Samsung Galaxy S phones.
8 $ ebay cheap wall battery charger power output specs:
350 mA battery charging speed - doesnt matter...
800 mA USB port.. THIS IS WHAT YOU WANT!! more the better. nice if the phone would use all of it... Need AC Mode...
Samsung wall USB charger is only 750mA! AND it will set AC mode.
The theory behind it is with samsung galaxy phones and "official chargers":
if the middle 2 data pins on the usb, while getting 5v to the outer 2 pins it tells the phone that it is an *official samsung* charger and enables full speed charging.
without the middle 2 pins connected (with or without data flow) will not charge at full speed. even if you supply 800mA it will only charge around 350mA
well there have been posts of cable hacks to do this or adapters... ha! tape and tinfoil... or hack the cable apart! And you cant use the cable with the PC anymore!
heres my mod... bend 2 pins.. DONE! solder if you know how for better connection!
***only use this charger for samsung phones, not all USB devices will like this, -may dammage some- as the samsung phone is PROGRAMMED to know what to do if the 2 data pins are shorted out***
Phone confirms AC charging NOT USB NOW!! But Camera Died!
Now i can leave my Samsung Charger upstairs, and this one downstairs.
You know how long it takes to charge an extended battery on USB mode? or at 350 mah in the battery charger?

Check out xda portal!!! Guess whos post made front page????
update on this mod..
was able to charge my extended battery from 8% to 100% in about 2 hours 45 min over USB with the screen off never timed before the mod but it was slower. In the official samsung charger it was a little over 3 hours. just in the battery cradle it takes around 5-6 hours. Very much improved!
Good tip ! sometimes I am almost 24 hrs.. this will help !
my old iPhone USB cable is capable of supplying up to 1A. it may be worth it to modify a cable, glue it in so it's no longer repurposable, and use the old iPhone wall adapter.
When I plug my old Blackberry charger into the phone, it shows "Charging (AC)" under the Status menu, is this saying that the Blackberry charger is putting the Cappy into full charge mode? Unfortunatly the charger does only say only 700mA output anyway.
yes its charging at full speed if it says AC. congrats.

More accurately, it means the phone will try to charge at full speed. I have an external battery that has the pins shorted, phone says AC, but it can only output 500ma, so it doesn't charge any faster.

MORE accurately (as said before) it WILL charge at full speed, OF THE CHARGER.. not the phone. UPTO the full speed of the phone.
thats why i said my charger upped it to 800 not 1100ish in the first post. and why i told the other guy his is working at 700. it depends on the chargers output, that has been explained thank you.
and your charger that is putting out 500ma IS FASTER. without the mod your phone is only charging at "usb speed" or around 375ma ish... just barely faster...
+1 on the BB charger, my Cappy didn't come with a charger and I always had it plugged to that BB charger, I'm used to measure the battery charging time of my old Dell Streak on a "desktop charger" and took about 4 hours, this cappy charges in 2 hours and something, maybe 3 haven't measured accurately but I know it is waay quicker than 4 hours.
I literally just picked one of these up last night! Will be doing this mod asap thanks for the info!

yes the blue light is normal. the pins you connect inside dont connect to anything in the charger, they are just connected to themselves.

The light is the indicator for if you charge the battery in the battery bay.
Am I right?
the light indicates power:
Blue for plugged in empty, or fully charged (battery or USB)
Pink if anything is drawing power (charging through battery or USB)
Purple if you have a battery and USB drawing power (over-drawing power!! disconnect one)
Hey Trusselo,
Nice mod. I bought of these with two after market batteries for $10. What do you think about wiring the battery contacts to a switch to the usb port to use the backup battery/charger as a portable charger? That way, you can go from charging the battery to using the battery aa portable charger?
Sent from my GT-I9000 using XDA App
i barely understand what you are trying to say, however, the battery contacts on the charger are only 350mah , the usb port on the CHARGER is 800, so wiring the battery contacts on the charger (with or without a switch) would be a bad choice.
you may want to re-read the OP...
No offence intended
TRusselo,
No offence intended by the previous post. I didn't mean to thread jack either. I was just wondering whether it would be possible to use the same hardware intended to charge a spare battery and use it as a portable phone charger using the battery as the power source. Thanks for the info; I was hoping to convert this charger into a portable phone charger as well as keep the current functionality (using the switch). Thanks for the info though.

USB car charger from Walmart

Can the GT 10.1 plug into any USB car charger?
I was looking at this from Walmart's website
If so, it'll be a lot cheaper than the car charger Samsung is selling

I've noticed that plugging into various USB wall chargers won't work. The only one that will work is the one that came with the tab. I am pretty sure this is because the Samsung one is a 2amp charger and all of my others are less than 1amp, 850mah specifically. If you can find a 2amp car charger then it should work fine. Otherwise, the charging indicator will show that it's connected to a charger but will have a red x on in it meaning that it's not charging or can't charge. I suppose anything too low can't charge the battery fast enough to make up for the battery drain

it's. still charging. you can get a trickle charge even from standard USB. s3ms that this is one of the only tegra2 tablets that can.
I heard that the trnaformer can but mine doesn't. it should work if I had USB.3.0.

i don't think the amount coming in will equal the amount discharged. depends on the brightness of the screen and how much cpu you're using. mine was charging veeeerrry slowly while reading the steps to root and the screen on, other than that it was idle and still slowly charged.

I also bought this. Arrived in 3 weeks from China, but free shipping, or $0.01.
They seem very good. There is some hard to read text (even in English) on the plastic part that tells you the top port is for iPad (2.1A) and the bottom is for others (1A). I've put a photo below of the guts. Seems it's definitely more than just some cheap resistors and a fuse.
I tried it in my vehicle and you still get the red X with a OEM cable with the device powered on, but NOT if you use an adapter plug found on eBay.
Do yourself a favor and order 3-4 of each. =)

Nope - you need a 2A charger, but any old 2A charger won't do. Most are designed for the iPad, which uses resistive voltage dividers in the charger to signal the presence of a dumb charger. Specifically the iPad looks for 2.0 volts on one of the data pins and 2.8 on the other.
The Tab expects D+ and D- to be shorted together and somewhere around 1.2-1.24 volts.
It IS possible to make iPad chargers (confirmed on Scosche reVIVE II) work as follows:
Bridge D+ and D- with a solder blob.
Remove the resistor that was the upper part of the 2.8v voltage divider (i.e. between the data pin and +5v).
At this point the charger should output around 1.2 volts on D+ and D-.

Car Chargers

Hey Everyone,
Thought I would start a car charger thread.
I picked up one of these at Walmart the other day:
http://store.griffintechnology.com/smartphone/powerjolt-dual-universal-micro
And it works quite wonderfully. It's tiny, and even with bluetooth/GPS/Navigation running, it was slowly charging the battery. And it charges it quite quick if you don't have nav running.
It can be a bit annoying to pull out once stuck in, although you probably don't need to do that very often.

I got it the other day but haven't driven far enough yet to need to use it
Glad to hear though that it charges even while using GPS.
what is the exact output of each USB of this Griffen car charger ?
i have a JABRA charger (comes with JABRA Cruiser) and it doesnt seem to charge my GN while GPS navigation is on (even though its saying charging on the battery icon)
it used to work perfectly on my HTC Desire HD (with GPS+Bluetooth+WIFI ON )
any recommendation on how to fix this please ? like a reference output current that is enough to charge the GN while navigating ?
thanks.

The Griffen claims 1A per USB port, and I believe it.
Online reviews say some users with other phones need to mod the Griffen to charge their phone, otherwise it only supplies 100mA. Some crack open/mod the Griffen to short two terminals to get the full charging ability, and/or use a 'charging cable' which shorts the terminals within the cable.
As a reminder, the Griffen seems to charge the Note full blast, but perhaps something similar is needed for the Jabra. I suggest installing 'Currentwidget' to see what sort of charge you are getting.

SGP has one as well, it will lit up BLUE!

OR you can just get a no brand one on eBay for around $3.

Thank you for the reply.
I have battery monitor widget installed & it shows charging via usb when i connect it to jabra charger, but the weird thing is that the galaxy note starts mtp mode once i connect it!
Could it be the cable? Or shall i just take the griffin charger to solve this?
By the way,griffin charger works out of the box out do i have to solder modify it?
Cheers
I just bought this dual port 2.1A + 1A charger on eBay for £2.49 inclusive and delivered the following day....
http://www.ebay.co.uk/itm/2-1A-Dual...neChargers&hash=item19ca66b4df#ht_2865wt_1163
At first it seemed the phone was only drawing a "USB" level of current, so I was all set to rip it apart and solder the centre pins to force AC charging, but when I double checked with a dry run and a temporary short the phone switched to AC charging. Now it seems to be continuing to draw "AC" levels, so maybe I had a poor contact initially and a few (un)plugging operations have made the contacts more reliable. I'll try it out later today with satnav running and see if it keeps up with the pace and report back.
EDIT : Charge level draining like water out of a sieve with this thing whilst running satnav, and the phone said it was "AC" charging too. Switching ports didn't help.
i'm using the official car charger from my old nexus, the only charger i found can charge my phone with 3g and nav on because of the 2A output. other cheap usb chargers i tried with so called 2A output just don't work

[SOLVED] Good external battery charger?

I'm looking for an external battery charger since I bought a couple extra batteries for my phone.
anyone have experience with a certain charger? Obviously I don't want something that will damage my battery but nothing that will break the bank either.
Thanks.

Anything wrong with the charger that came with the phone??
I need a charger that I can put a battery on so that I can use my phone out of the house and a second battery can be charging at home..

Yeah, sorry I probably should have been more specific but I dont know the exact name for them. haha
It's like the dock "travel" charger for just the battery, not the battery connected to the phone.
I havent been able to find something decent (crappy charging, made in china).
Ok a little update for those interested.
I ended up buying some cheap (REALLY cheap) charger off ebay not expecting too much but just experimenting.
The charger itself looks something like this:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
The 2 metal prongs connect to + and -; the charger is able to read which is the + and which is the - no matter how you set the battery in there. The bottom part that pushes the battery toward the prong is extendable or you can flip it 180 if you have a really small battery.
-Flashing red and blue light means charging
-Dull red light while plugged in means fully charged
-Dull red light while not plugged in but with battery set up means the pins are set up correctly on the terminals
NOTE: do not take batter off/put battery on while the charger is plugged in. It can ruin the battery.
The exact one i bought:
http://www.ebay.com/itm/270908124203?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2649
(no problems with the seller, they actually sent me a few free ones due to a misunderstanding)
Now for the review and my experience.
Pros:
-Fits any battery, interchangeability of pins (differentiating + and -) means you can fit any battery really
-Has a side USB port so you can charge a battery and plug in your USB cord to the phone and charge it at the same time
-Voltage input is 110-220V so (with an adapter) you can theoretically (will test this summer) plug this charge straight into an european plug or north american plug.
-No problems so far with over charging; Charger stops charging the battery when it is full
-Has a light to tell you when the battery is done charging and when you have the pins connected correctly to the battery
-Compact; Small and plug folds up into unit.
-Charges a fully dead battery quickly.
Cons:
-No instructions when I first received this product (i know what you're thinking, how hard could it be to just charge a battery but I was reluctant to rely on the self detecting terminal feature)
-While charging, the light on the unit (the one i posted/bough) flashes red and blue like cop lights and is very bright so it might be a problem if you are plugging it in overnight in a bedroom. Also this is a normal function of the charger but i thought it was malfunctioning so they sent a new unit but then figured out its normal.
-Looks cheap
-Dont know how long it will last for (really cheap so buying another one isnt a problem)
-Noticed that after i pull a battery off the charger and use it the phone states it is at 99% (undercharged) although if i try to bump charge a fully charged battery it wont charge more. This could be a problem with my battery/phone/etc.
-Nothing else really
So final verdict on this product:
Its a great, affordable charger; works great if you are traveling and need to charge an extra battery. Will fit the Incredible 2 extended batteries and technically virtually any battery. Its pretty easy to use once you know what the color lights mean and how to set a battery up.
If anyone has any questions or want more pictures of this product just reply in this thread. Hope this helped out anyone looking for a product like this.
