[Q] Real 2A car charger. Which one??

Yesterday I've been navigating again with Navigon on my SGS2, but unfortunately it slowly drains my battery. When using google maps it dous charge the phone. So apperently Navigon is using a lot more 'juice' compared to Google map navigation.
Do you people know a charger (I assume one of 2A, while my own charger is an 1A charger) which does charge the phone with bluetooth, gps and Navigon running?

I bough a 2.1A car charger from belkin and I still have battery drain.
Even with the phone detecting it correctly as AC CHARGEr.

Hmmm that's to bad
Ordered a 2A charger from ebay myself.... But I doubt it will work, especially after reading your message.
I think the phone only takes a maximum of Amps for charging, even though it uses more. Resulting in a slow battery drain.

Note that it will stopped charging if the battery gets too hot to avoid damage or possibly exploding the battery.
Obviously having a higher rated charger will heat the battery more, so make sure the phone has its back ventilated, and try avoiding direct sunlight.
Read of several people that had this issue, but got their phones charging when avoiding overheating it.

Try the Rockfish premium charger. It's 2A and looks nice.

has anyone had any luck with the motorola charger? I bought one for my nexus one + car dock and it always worked fine... have yet to have a chance to use it for my SGS2 though..

But that's a bit strange, because a charger should deliver what a phone is asking for. As far as I know, a charger doesn't push the charge to the phone. But we will see, if the phone does get overheated, then that will be the end of the charger.

You're mistaken.
The thing that you plug into your car, that's called a power supply.
The real charger is built into the phone. That's the charging circuit that will shut down the charger, stop drawing power from the power supply when the phone gets too hot.
I doubt the phone will be able to take 2A, and the circuits will prevent the phone from drawing 2A of current.
#1. So, what you're looking for is actually a power supply that provides suficient current. Most car chargers will be about the same.
The power supply is connected to your phone via cables. Badly made cables will not be able to supply more than 200mah, and as a result you're going to take a really long time to charge your phone, and with a high drain application going on, you're not going to be able to charge your phone.
I had that exact same problem previously, and it was because of a lousy batch of oem cable I bought from ebay. Original, and other brands of oem cables worked fine.
#2. You need to buy some proper cables. I buy from www.monoprice.com, because I like my cables to be gold plated.
Edit: No, I'm not related to monoprice. I just love my gold cables plated heads. Can't find them cheaper anywhere else.

But the quality of the cable is not the only thing. The phone should also see the charger as an AC charger instead of an usb charger. This can be done by connecting the middle pins in the usb cable. Otherwise it will only charge with 500mA.

Is there a car charger you can buy that does this automatically? (i.e phone thinks it's plugged into AC rather than USB). I'd rather not plug anything i've been messing about with into my beloved SII.

It's not about the charger but about the cable you're using.

[Q] Car charger keeps disconnecting/reconnecting when i try to charge s3?!

i have one of those bullet usb car chargers and i recently tried it out with my s3 at 15% battery life and it keeps comming up with the lower battery warning while i'm connected to the car charger and the status bar shows one moment it's charging, one moment it's not! I opened up this charger and the data lines are by default shorted together. The charger is rated at 1aH max. Any ideas?? I've attached pics of the insides of the charger.
Suggestions are welcome. I've just been using my s3 wall charger off ab inveter since switching to android and it's getting pretty annoying.

Does the charger work with other devices?

USB port bad on your S3 possibly? My s2, i remember, when you pressed it down it disconnected

Try a different charger.
Not all chargers agree with all phones.
If it's not out of the question just get a new car charger made to work with the t999.

No problems charging on other chargers or charging My s3 with this car charger when the car is off with the car battery left on. When the car engine starts, the voltage of the cigarette port drops from around 14.5v to ~12v

It's a 12v power source.... Can you try another car charger?? What model is it?

When a car isn't running though it's around 14v...this is when my S3 has no problems charging on this charger. I have some usb car chargers (idevice chargers) that don't have the data lines shorted and these work fine with the S3 apart from them not charging at 1aH.

problems charging the note 2 in the car - any ideas?

here is my setup in the car and i can't get the note to charge - well, it does say its charging but at best it will maintain my charge level it never actually charges
dedicated charger into my fuse box
note hooked up with mhl to my pioneer appradio 2
gps running, mhl running, bluetooth running. i use a screen off app to totally black out the screen.
now, this setup with my gs3 worked perfectly it would charge the gs3 like crazy as fast as a wall charger it seemed. with the note it will never increase in charge but at best maintain or slowly use charge. the power it is getting cannot keep up with all the tasks its doing.
now, i know this phone is a beast...but can anyone think of anything for me to try or buy to get this charging no matter what? i figure it may take custom kernals or something like that to finally get it done.
that being said - if you are using an android phone you absolutely must check out the pioneer appradio 2 with the appradio liberator app. you hook the phone up via mhl and with the app have full touchscreen control and mirroring of your phone on the 7inch touchscrreen radio display its pretty awesome.

I know the wall charger is a 2A rated charger....which is built for tablets. Perhaps attempt to locate a travel charger rated as such. I'm no scientist, or electritian so I cannot attest this will work, but just thought I would throw it out there

my chargers i the car claim to be 2a but doesn't seem to make a difference. hell, the one charger would chage an ipad in the past

most samsung tablets need an adapter to "trick" fast charging mode on non-samsumg chargers. otherwise it'll just trickle charge. i've not tried any yet but seems i may have to since the gnote2 is gonna need the same juice as my gn101. kinda what i expected since they're pretty much the same specs.
here's a thread to make your own adapter:
http://forum.xda-developers.com/showthread.php?t=845844
page 9 has a few links buy your own. just put .com in place of .co.uk on the ebay links.
here one for $3. ships from china so it may take a few weeks.

the stock AC charger supplied with the note 2 is 2A. I also have a 2A car charger. I cannot get the note to charge at any rate higher than 1A. Yes, i do know the trick to get the phone to go into fast charge mode. I have a feeling that 1A is the most we are going to get. Yes, if you have a ton of stuff running all at once you are going to use more than 1A and end up with a dead battery after a while. It does suck. My previous phone (Epic) would not charge beyond .5A. It died while on my car charger ALL the time. Hopefully this one wont die quite as often.

Yes, the trick i use is to short the two data lines going to the phone NOT towards the charging source. If you do not do this the phone will be in USB mode which will only allow a charging rate of .38A. This seems to be an android/usb standard across almost all vendors. once i short the data lines that is when the phone will go into full charging mode. The highest i can get the phone to go is 1A and this is even with the supplied Samsung 2A charger. I have also tried an iPad charger and it still only produced 1A to the Note II.
The Note II also seems to vary the input current based on how much battery is left. If the Note is very low (i.e. 50%) it will go into 1A. If the battery is high (i.e.95%), the current will bounce around. I have seen it start at .5A, jump to .8A, then to 1A, then right back down to .5A and it will continue there until it reaches 100%.
Bottom line i have not seen anything above 1A
JD

at least one of the adapters on the other thread claims 2A, but i don't think i've seen anyone with those results.

this is a pretty ridiculous problem for samsung to do nothing about is it not? the notion that you can't even charge your note in the car is a bit ridiculous. i wonder if someone makes a kernal with fast charging enabled if we'll be able to get around this

you can charge, just ridiculous slow. i occasionally charge my galaxy note 10.1 on my computer's usb when i'm too lazy to whoop out the charger. i do it a work where i know i won't use it for 8 hours.

You can't charge if you are intensively using the phone though. it loses charge.

Is there a specific car charger yet for the Note 2? I imagine this issue will be resolved with that charger.
People with the HTC Flyer/Evo View had similar issues. Unless we use HTC proprietary car charger, you lose power while plugged in. Standard usb chargers, charge it very slowly.

I am using the PowerGen Dual USB 3.1A 15w High Output Car Charger since it claims to be a 3.1A charger. What I thought was a fast charge was in reality not. Using the Current Widget app (which shows you the mAh) it registers 9882 mA for one of the usb slots and 10005 mAh for the other using the Galaxy Note 1.

[APP][ROOT][KT] Fast Charge Toggle widget

I love @ktoonsez kernel I also LOVE his fast charging option. Was using schools computer to charge and was charging at 900 mA love it.
Got tired of going through the app to toggle this. So i made a widget that can be placed on the home screen or the lock screen. Im sorry, the image is hideous. xD wasnt too sure of what to use as an image so bear with me xD
Just install the APK then either on your home screen or your lock screen add a widget and select Fast Charge Toggle. Done. Will prolly work on other kernels with fast charging option but only tested on @ktoonsez kernel

From almost totally dead, it takes me about two hours for a full charge with normal charging.
I've never bothered with tweaking charging settings. How much faster would fast charging accomplish the same thing?

Like the idea, but what does fast charging do ultimately to you're overall battery life and health long-term?

It has no side effect on the battery. The stock charger has I think like 2a charging power, most computers have only 500mA. Fast charging simply tricks the kernel into thinking it's plugged into a wall outlet and charges at the full power available. The only side affect is that it could ruin the USB port. However after two years of using it I have never seen any issues myself nor have I read any.

According to what I personally saw in the source code and what @ktoonsez said, the fast charging gets ignored when it's an ac charger. Just going off of source code and what the code actually does. Might just be a placebo effect on your end all in all tho fast charging sure is the best thing since sliced bread xD

I have a car charger that has a spare USB plug on it. If I use the actual car charger it charges as normal, but when I plug in the white USB cord that came with the phone into the same car charger it definitely charges almost twice as fast. Living proof. I was on a road trip using GPS and LTE while streaming music. While on the car charger it would almost not charge at all, just supplement enough to not drop in percentage. Then, when I switch to the other USB it charges up no problem.. Really works.

Elesbb,
First off, Thank you for making this and sharing it to the community. I have been looking for something just like this. Comes in very handy.
I don't know if you update this anymore, but I was wondering if you could make a choice for different icons for the widget. If not, no big deal, the icon is just a little too cartoon-y for me.
Thank you!

I just googled "maximum usb milliamp output from a standard computer usb port" and to my
surprise I must have found at least 25 links which I read that deals with this subject.
And all of them specifically point out that a normal laptop or desktop computer's usb port puts
out a maximum of 500 milliamps unless someone has some special usb pci/pcie card installed
inside their home computers, I never seen any that do but it is possible that such a card exists.
So this mod would really not do anything at all, it would not charge faster and it could not hurt
the usb ports of any computer since it cannot change the max. milliamp output of the usb port.
Now if we had some kind of special program which we install in our computers to allow the usb
ports to put out 2amps (2000 milliamps) then it would charge just as fast as our wall AC chargers do.
But modifying anything inside our phones cannot change the fact that it's the computer and it's usb
ports which determines what the maximum amount of milliamps that it can output.
Look at it this way, if you have a 5 gallon gas can you cannot pour 10 gallons of gasoline out of it.

The maker of this (ktoonsez) stated this in his thread. However, a lot of computers (newer ones) do have higher power outputs to power things like external hard drives, cooling fans... etc. For instance, mine, when paired with the fast charging mod, outputs 700ma but without, stays at 500ma. So while you are correct, there are a lot of computers (especially newer) that do have huger output ratings. This is clearly seen when my external hard drive won't work on my grandfather's dinosaur computer (even his new printer has issues). But plugged into my laptop, it's has no problem.
Also, I believe USB 3.0 has a 1amp output.

You know what, you are just about right, I just did some more googling and found
that the usb 3.0 ports on newer computers do have a greater output than 500milliamps.
They have a maximum of 900milliamps, still no where near the 2000milliamp which
the home charger puts out, but it's close to double of the standard usb 2.0 ports.
I read that many newer computers including mine has a dedicated 3.0 port which stays awake
even if we turn the computer off & it continues charging whatever is plugged into the 3.0 port.
So 900milliamps is a lot better than 500milliamps when comparing usb 2.0 to 3.0 however
current is current, the phone itself cannot distinguish between a 500milliamp or 900milliamp
charging rate, if it gets 900ma it will charge a lot faster than if it only gets 500 milliamps.
All cell phones have a safety feature built into their circuitry which prevents us from charging
the phone at a higher rate than what Samsung specifies by plugging it into a charger which puts
out more than 2amps, if the phone did not have that circuitry it would dramatically shorten the life
of the battery.
That's why Samsung ships 2amp home chargers with their phones and not a 2.5 or a 3amp one.
If this mod which is being discussed here defeats the safety feature in the phone's circuitry which
prevents it from being charged too fast then I would highly advise against installing or using it.
The only time a higher rated battery charger should be used is if we have an extended battery
which was rated at let's say 4200milliamps in which case a 3-4 amp charger would be best.

It doesn't defeat the security of built in kernel protection. Androids own API has a way to detect if the plug is wall charger or USB. The mod simply tells android OS that the USB charger is an AC charger and to not limit charging to USB levels. That's why USB doesn't work when the mod is enabled. It's no way harmful to the device. Been using it since I've gotten my phone and even back on my s3.

Just install the APK then either on your home screen or your lock screen add a widget and select Fast Charge Toggle. Done. Will prolly work on other kernels with fast charging option but only tested on @ktoonsez kernel

You're right!! The widget is the ugliest thing I've ever seen but it works perfect! Thank you much!!

It doesn't defeat the security of built in kernel protection. Androids own API has a way to detect if the plug is wall charger or USB. The mod simply tells android OS that the USB charger is an AC charger and to not limit charging to USB levels. That's why USB doesn't work when the mod is enabled. It's no way harmful to the device. Been using it since I've gotten my phone and even back on my s3.

Okay, see what you mean.
Did you know that there are 3 or 4 free apps at the playstore which display the amount of mA
the phone is being charged with at any given time, it also displays the maximum mA that the
charger or usb port can charge. Here are a couple links in case you or anyone is interested:

Charging The 10.1

I lost the original charger to my 10.1 2014 Edition and I've had problems ever since. Earlier this week I thought I would order a Limefuel 24W 4.8A dual port rapid charger. I thought to myself: Hey I can untick Power saving and have all my needed apps running. Even using a root mod to run 4 way multitasking. Yet it's still sucking up more juice than the charger is spitting out. Am I doing something wrong or did I get a faulty unit from China? This was NEVER a problem when using the Damn Samsung charger along with the foreign adapter dongle it shipped with. I thought getting one so powerful would charge it even faster.
Maybe I should just ship it back and get an official unit from Samsung? Although I don't see how getting less energy will make the tablet charge any better

4.8 amp should do the trick. Could be a fake unit. Is it heavy? 4.8 amp is pretty much, so it should be as big as a lap top charger.
But remember , a cheap usb cable may also be the problem. Try a short one of good quality.
Edit.Just tried a 1.2 amp Nexus 5 charger on my P605. Charging good on full brightness.
Thanks

The charging circuitry and s/w on the device determine charging speed. Do a search. Someone posted the different charging amperages using the stock charge and Apple and HTC chargers and USB cables. The device detected the latter and charged at about half of the former.

Yes thats obvious and i doesnt even need to " do a search ".
The problem was it wouldnt charge at all.
Thanks

Does the p600 also not charge correctly with a non samsung charger? I remember my p1000 requiring an adapter that had a resistor between two connections to charge correctly at a laptop or different charger.
