Car Charger

Having some issues where, while using Navigation on the S3, the in-car charger that I have (Generic USB adapter) only slows down the discharge, the percentage goes down.
Is there any difference in in-car chargers? do I need a more powerful one?
Grateful for any advice

Common problem with weaker chargers or USB, the latter usually charges at 500ma which is the USB standard. Get a 1000ma charger for it and you will be good to go.

Thanks for the advice

I ordered a 2 amp car charger at the time of my preorder for this reason.

Lots of USB chargers suck pretty bad, even ones rated high amp. Some give false ratings.
This one is quite often recommended here at XDA and it's the best one I've tried so far.
HTC T-Mobile myTouch 3G Car Charger - Black

It lets me use Pandora, GPS & screen on at the same time.
It won't give me a charge up, but it does help to prevent the battery from draining.

Battery charger that will "keep up"?

Hello guys
I have a cheap USB charger I got on eBay.
I use my phone as a dash board cam (with the screen on) and the battery decharges faster than the charger can charge it.
Will it be possible for me to find a charger that will "keep up"
Thanks a lot in advance!

it could be either the usb cable if it's not stock or damaged but it very well may be the charger, look for a little bit higher end charger (as in not the cheapest one you can find) and it should work

The specs in the item description says 500-700 mA output at 5VDC. Not only is that low output current, but most list a minimum spec, not a range. You can probably assume 500 mA output for that one, which is not enough. The battery will discharge at a higher rate than that charger can provide.
Anyway, look for one that is rated for 1 Amp (or 1000 mA) output at 5 volts. This should be sufficient. I still use my HTC 1A charger that came with my Nexus One car dock for that reason.

Samsung phones seem to have 2 charging profiles, usb gives you around 450mah and ac gives you around 650mah.
650mah still isn't enough when doing nav/bluetooth streaming, until samsung starts using a full amp for charging you will never have a charger that will keep up.

motorola fast charger
you can use this one:
Search for "Motorola Vehicle Power Adapter micro-USB Rapid Rate Charger" on Amazon
I have been using this for quite a while now on Nexus 7, its just awesome. It has an output of 950+mah which would be enough for Nexus 7.

I used this Griffin-Powerjolt. Found it at walmart, and took it apart and soldered the two middle pins. But found my info here on XDA, but cant seam to find the thread. And I can play games, stream music, etc, and my charger keeps up and charges fine. But this post sums up your question.
Also I'm on AOKP JB and when I was on there ICS roms they have the charging mod so even when I had a cheap-o 500mah charger it saw it as an AC charger and charged at AC charge speed. I think also Cyanogenmod has implemented this also, but im not sure.

+1 for the Motorola charger recommended earlier. It puts out 950ma so the phone will read charging via 'AC' rather than 'USB'. Charges quick and will be able to keep up with BT and GPS navigation. Here is a direct link:

I've been using it with all of my Android devices and works very well. Great quality as well. Highly recommend!

I use the 2A Amazon branded charger. You'll want to set it in fast charge, because the phone thinks it is a usb charger. You can open it and short the pins, if you want.

Actual current draw (aka...how fast your phone charges) is not determined by the charger but rather by the phone itself. The ratings on the chargers is what they are capable of, but will be dependent on the device. People would be frying devices all the time by using one device with anothers charging cable that has a totally different output if it was determined by the charger alone.

x3 on this charger. Have used it for the last couple of Android phones as well. Work fantastically with my Nexus streaming music via bluetooth to my car stereo. Never has a problem keeping up.

I'm using my N1 charger still too. Keeps up with nav, stream music, and max brightness. I don't use BT, but otherwise I always gain quite a bit of charge.

oh in another way, you could install a custom kernel and enable fast charging, works for me though.

I bought 2 of these charging only cables. They work perfect, full "AC" charge through any car charger port.
http://www.amazon.com/gp/product/B007F1DV76/ref=oh_details_o02_s00_i00
Put one in my car and my GFs car.
The problem is a "USB" charger spec doesn't allow for the higher voltage charging under most situations. Any cable that does provide the full "AC" charge is a 'non-USB compliant' charger (or something like that), thus, the cable I listed above doesn't say "USB" charger. That is a very brief explanation.

That works fine but I heard it uses your battery faster.

[Q] Stweaks, Car Charger, Currents - Need clarification

Hi everyone,
I have few questions regarding Stweaks and in car charging.
Phone - Note 2 7105 LTE
Charger in car, 2.1A (confirmed it can output enough of juice)
Charging cable - iBolt xProDock (9ft, one with AUX and microusb "in one")
I am getting 800ma charge no matter what. With regular charging cable in same car charger I get arround 1700ma.
In both cases my charger is recognized as AC
Now as I understood (probably wrong) it's due to limitation of the "Docking" feature in Samsung phones which limits charging to 700ma or something?
So, I rooted the phone and I am running Wanamlite with 2.7 adam kernel together with Stweaks app.
As my car charger is recognized as AC, I assume there is no point in messing with SDP and CDP values (which are at 475ma and 1000ma values by default)?
DCP however has default values of 1800ma input and 1700ma to the battery.
Only thing i did was to tic the box "Ignore unstable power" and now my phone is charging with 1700ma in the car. So far all good, at least on paper.
My question is if it's SAFE to have the settings like that in CAR? or should I lower some of the values? I assume if i fiddle with those value (downscale) it wil also negatively affect my charging with regular in-wall charger?
Thank you

GRIFFIN Dual USB Car Charger issue

Hello everybody,
I have recently bought the Griffin Dual USB car charger.
I use quite often a GPS navigator when I am driving, so I wanted to buy a car charger which was powerful enough to sustain gps and 3g data plus a little extra juice to charge my phone battery. I found this charger on the internet and the specifications say it's got an output of 1A which should be more than enough for my needs. However, I was quite surprised when I realised that the battery still goes down really slowly when I use the gps app.
I've had a look online and apparently most car chargers are not recognised by your phone as a proper charger. For this reason, they provide only 500mA. You can double check this by having a look at 'settings > about device > Status > Battery status'. If it says 'Charging (USB)', it provides 500mA. Instead, if it says 'Charging (AC)', it provides more (so called fast charging). Well, my phone says Charging (AC). But it's still not enough apparently
Do you guys know any app or anything I can do to test how much the charger is actually providing?
As you can imagine, this is quite annoying.
Thanks

i'm in the same boat as you but a different dual USB Charger
It's suppose to output 2.1A + 1A or something along those lines and it does charge last generation iPad and an iPad Mini at the same time without an issue.
When I plug a Galaxy Nexus in it charges as a USB BUT when I plug the Galaxy S3 it charges as AC but a 2 hour trip only got my phone battery up to 47% which is way way too slow and that is without GPS
The AC charger that came with my phone only outputs 1A but it charges my phone in 2.5 hours from dead flat to full

My car charger is the same. 2.1A port for tablets and stuff. 1A port for everything else. I have noticed that if I plug my s3 in the 2.1A port, it charges slightly faster. However, it's not even close to my 1A wall charger.

Hi, if you are looking for a best usb car charger for your device then i have a option for you. Please check my profile and fo to the link in my bio.. Thank you

I recall back with my old phone (Virgin Mobile LG Optimus V), the lead devs teamed up and made a flashable patch that allowed you to toggle fast charging on and off, basically telling the phone whether it should consider the power source a USB or Wall charger and it worked good. Maybe we can get some people to team up and build that for the S3?

Any way to force fast charge when charging via USB

Any way to force fast charge when charging via USB
When charging with wall outlet with original LG charger the phone charges pretty quickly.
However when charging via USB in my car there are time it will charge slowly (which I can deal with) but there are other times it will not change quick enough resulting in the battery actually losing charge. What is weird is I can't figure out the variability as the load should be pretty consistent (screen on, bluetooth on, GPS on, car home ultra, navigation and stream music).
I had a Galaxy Nexus that had the same problem but was able to resolve it with combination of using a power only USB cable and custom kernel that support Fast Charge which I set via Trickster MOD. I am using the same setup except I can't find an equivalent way to trigger Force Fast Charge.
I am using GSam Battery Monitor to try to diagnose but am getting confusing results. The mV reading varies from time to time from -1000ish to +1300ish.
Is there a way to solve my problem?
Thanks in advance!

What is the rated amperage output of the car charger and have you tried using the original LG cable with it?

If the port on your car isn't putting it enough amps it will never fast charge. Try getting a fast charge car charger.

Hum... I didn't think about checking the output of the car charger. Thank you for the suggestions. I think that is the problem.
I have a GoGroove FlexSMART X2 Mini (http://www.gogroove.com/GOgroove-Fl...eless-In-Car-Bluetooth-FM-Transmitter-pid9385) and I found out its output is rated as DC 5.0V 600mA. I think I'm going to need to get a twin socket adapter, one socket for the X2 mini and one socket for a fast charge car charger.

Buy a 12VDC charger with at least a 5V 2A output and you should be good.
