Total GPS/Car charging kit - $11.37!

So I went onto monoprice.com and was able to get a complete car kit that included a cigarette to USB adapter, 3ft USB to 5-pin microUSB cable, and universal car mount, all for a total of $11.28 $11.37 including shipping!
the individual items are:
cigarette to USB

I hope this helps anyone who is looking for a cheap but effective mounting system for their car
EDIT
The adapter did not charge the phone correctly, so my phone would drain faster than it would recharge. I went to amazon.com and bought a car charger that should work great, and only ends up making the total a few cents higher

Wow. Good price there.

The output of the car charger is 1000ma, the stock wall charger is 700ma I believe. You think it'll hurt it? If anything, I think the phone will just get warmer than normal when plugged in.

that's the car mount I use. Picked it up from there, really cheap but you get what you pay for. Its an ok car mount but not great.

Well hey, it'll work right? Lol.
As for the charger, I'm not sure. I don't think I'll do anything bad really.

dam thats not a bad price!

Just a FYI
Even though the car charger is rated at 1000mA, it does not have the D+ and D- pins shorted together. This causes the phone to think it is connected to a data only device (and not a power supply). Because of this, it only draws 500mA, which when using with Navigation actually causes more drain than what the charge is.
It's a simple fix though. Just pull apart the charger, and solder the middle pins together (look on the underside of the board, and solder together the two middle solder points). The proper way to do it, and the way I did it, was to bridge it using a 200ohm resistor.

Ask that kinda sucks. Well I'll see how it works before I try anything. Is there a canker on that site that will work correctly? Or is the problem with the car to usb rather than the usb cable itself?

I bought one of these chargers for my duaghter before this thread and it does not work with her Vibrant. Guess I will have to mod it.

You have to be a hard core tweaker to break down an solder a $2 cable. I wasted more than $2 worth of time just reading the post about it.

Ok, so it didn't work. The phone just said that the usb had been plugged in, but it didn't charge. I took a pic of what the charger looks like torn apart, can you tell me where I need to souder? Am I going to have to tear open the usb casing, or is it something I can do without tearing it apart any further?

So I grabbed another car-to-usb thing, and now it says It's charging but It's apparently draining faster than it is charging :-( it doesn't even seem to be slowing down the drain. Do you guys think that a different cable might affect things, or should I just get a new charger/adapter?

I don't have this charger, but try using the cable that came with the phone. If its the same, then try to exchange it or using a different cable.

I also bought mine from monoprice and it does not charge. It only drains .
Will look for alternatives.

I just did a few quick searches, because like a few others have said, it drains faster than it charges when using navigation. Not good if you're on a long trip.
Also, it is not the cable itself it's the charger that is not correct. I used both a monoprice wire and the oem one that came with phone. Just as an update, I have noticed that while soldering the points helped a little, it is still not pulling as much as even the stock wall charger (which is only rated at .7A). I found this out by going to the file /sys/class/power_supply/battery/batt_chg_current.
-While plugged into the wall ithe value is showing 1050 on average.
-Plugged into usb it shows 850 on average
-On the modified car charger around 900 on average.
So even with the mod it still doesn't pull the full amp and still drains a bit quicker than the charge

You can try the fix and see if you get better results than me. If you look at the port that you would plug in the usb cable, (from the angle you took the picture) you will see four pins "bend" down into the pcb board. These are the four pins I am talking about. The outside two are for power. The middle two are your D+ D- (data) pins. if you flip over the board you will see the 4 factory solder points, just add a dab of solder to the two middle points.

I bought this combo as well and the charger works fine for my usage: pandora on my one hour commute. I can't get navigation to work right (and I know how to get to work so I have not tested that.
Only flaw so far is that the audio cable from my phone placement on the windscreen to the aux-jack in for my stereo is an inch too far than my cable can reach. Time to get a longer cable.

I just went ahead and bought this on amazon.com
http://www.amazon.com/gp/product/B003WRBGK6/ref=oss_product
This should do the trick, and when coupled with the gps mount is only a couple cents more than buying the adapter+cable
it would make the total package... $11.37

what do you guys think about this one?
http://www.amazon.com/Portable-Char..._21?ie=UTF8&s=wireless&qid=1282314027&sr=1-21
suppose to replace car / wall charger as a one unit...

The new car charger works great when my phone is asleep it will fully charge in under an hour! The only thing is, with my screen all the way up using gps it still drains a lot faster than it charges. When I turned the screen down, it didn't seem to go down at all in the 5 or 6 minutes of driving I did. Does this screen really suck THAT MUCH power??? Are there any chargers out there capable of charging this phone well enough to allow for full screen brightness while using the gps functionality?

[Q] Original Samsung Galaxy S2 Car Charger

Hi, I'm looking for official samsung galaxy s2 charger that is without the car mount/ holder. anyone knows where can i get it ?

Is this a genuine samsung charger? I'm using a generic car charger right now and the battery drains faster than it charges while using sat nav.

I bought one of these chargers too (the CAD300U). It charges the phone ok, but if i'm using the sat nav the battery drains faster than it is charged, which makes it pretty useless.
Anyone got a suggestion of a good charger that will charge the phone even when using it as a sat nav?
Whilst i'm on the topic. What have people found is best sat nav app for the UK? I find google maps to not be clear enough. The route marker is the same colour as the motorway.

I use this:
http://www.amazon.com/Kensington-K33497US-PowerBolt-Charger-Compatible/dp/B003PU01M4
The phone i heard only pulls 650mA so this is way more than enough (2.1a and 1a). safe to use as phone will only draw what it needs. if you use a regular charger they only supply 500mA usually. this results in overheating of charger as the phone will attempt to pull 500mA +. It will also drain your battery as your GPS will probably pull 500mA +
This will probably charge your phone during GPS use instead of just keeping it on.
+ it has another slot so if you own more than one USB device its good to go

I bought the official Samsung one, it was 700ma the charger which was great. But the biggest issue was the ground loop interference from the car (and I am not the only one to complain).
Samsung could have done a better job, or provided a 3.5mm cable with the audio filter in it.
Be warned, £35 for the official one may come as a big dissapointment.

That Kensington doesn't have great reviews on the uk amazon site. people saying it doesn't fit the cigarette socket very well - too tight.
I also found this one from Belkin: Belkin Micro USB CLA Adaptor (F8Z445EA)
But can't find any info on its mA output.
edit i take that back. apparently it can supply "despite being able to deliver 1A at 5V USB power". so that should do the job nicely.
also, how do i get the mods to validate my account so i don't have to wait 5 mins every time i want to post something? - i have tried to find out in the general XDA forum, but there doesn't seem to be any mention of it

Im using this: http://www.sonyericsson.com/cws/products/accessories/overview/an401?cc=gb&lc=en#view=features_specifications
Works great for me. I have used it with gps and bluetooth on a road with terrible signal coverage without any problems.
stratplayer
If you get ground loop interference when connecting a 3.5 jack, you probably have a grounding fault in your audio system.
It happened to me, I found out that one of my speakers toutched some metal in the door. The grounding circut in your cd player may also be broken, so when you connect the phone it may try to ground itself through your phone. If you have an external amplifier, you can try to ground the rca cables. You can also try to ground the cd player housing.

For gadgets like this I usually go to Amazon. There are plenty of choices out there. I use Avantek for my S4. Rock solid. Haven't used a S2 myself but I think it will charge your S2 w/o any problem.

Brodit active car holder won't charge the S2

Hey guys,
I got my brodit active car holder now for a few days and it seems it doesn't supply enough juice to the S2 while in use :-(
While navigating with navigon, it even loses charge, though it's connected .... that's really disapointing, since brodit normally supplies quality products.
Anyone else got the brodit active holder with the same problems?
boba

Not got the Brodit, but I have the same problem when using CoPilot and charging via the USB cable attached to a car charger. It can keep the charge at current level with CoPilot on, but will only charge with CoPilot off.
Also noticed if SII has less than 50% charge, it won't charge at all with CoPilot on.
Taking a punt on one of these to see if it makes a difference:
http://www.buyincoins.com/details/d...-for-ipad-iphone-4g-ipod-2a-product-2748.html

Which holder do you have exactly? Can you make a photo?
Does it toggle car dock in the S2? You can see a steering wheel in notification bar.

I was thinking exactly the same thing this lunchtime. I have the cigarete lighter active Brodit mount and - if i makes any difference - a 2004 Vauxhall Astra H. I as wondering if I would have to turn off the nice things [like satellite view, etc] on the phone for it to survive the journey. Not happy.

Is the S2 in USB AC Mode?
Take a look here: Einstellungen - Telefoninfo - Status
Yesterday I modified a Brodit active car holder from the good old htc HD2 to fit the S2. Now I have fast charging (AC) and Car-Mode.

I currently own some chargers. Not the original one, well the UK Version with no use in Austria.
A 1A HTC Charger with USB socket, a 450mA noname charger with USB socket and a no name car charger with micro usb.
The car charger and the HTC charger show charging(AC) whilst the noname 450mA charger shows charging(USB)...
It would be interesting to measure the exact mA taken by the phone...

Hi all,
Okay, I've now tried four different chargers, and I've also had the phone replaced. Today, in a last attempt, I bought an official Samsung charger.
NONE of them work - even though the phone says "charging on AC" for all of them.
The only thing I haven't tried is a different car (which I'm going to do, once my neighbour gets home).
The one sensible suggestion I've read is that Samsung have screwed up somewhere in software and the phone can't draw enough juice.
Electronics is beyond my little brain, so I don't get why the GS2 charges from my netbook (even when it's only on battery) but won't charge in the car.
And I'm not talking when I'm using satnav. It won't charge at all. In fact (weirdly) it actually DISCHARGES much faster than it does if it's just sitting in my pocket.
I've logged this with my provider (Voda UK), because I refuse to get stuck with a useless phone for the next 18 months if this isn't sorted out. It's ludicrous. If I can't charge the phone in the car it's as good as useless to me.

UPDATE:
Okay, I just tried my neighbour's car (Vauxhall Astra) and the GS2 charged perfectly. 3% in four minutes. Pretty much what I get off the mains charger.
I wish I knew about electrics but I don't. Explanations will have to come from the boffins round here.
I tell you what, though. I don't really want to get a new car just to use my phone properly

Do you have any chsrger with a led?
If the led stays dark the cigarette lighgter of your car might need a new fuse.
Which car?

You might be able to change to a higher amp fuse in your car fusebox.

Brodit mount arrived and looks great. Fit and design excellent and seems to charge as I would want.

So what charger do you guys advice? Which charger does charge the phone, even while navigating with Navigon?

I got the Brodit active charger (BR512...), there isn't a problem with charging at all.
I think the issue you got is really car related. My guess:
a) your cigarette lighter port is poorly wired -> Measure voltage at the port with a voltmeter, it should be at least 12V DC (Edit: Even if it does there is still the possibility that your wiring is bad, showing 12V doesn't mean it can handle the current this charger needs)
b) your cigarette lighter port doesn't make a good contact to the brodit plug. Check for corrosion of the contacts, dust, dirt, etc. Some ports go bad after lots of plug in / out cycles.
If you have no idea what I'm talking about here, I'm pretty sure every car mechanic can fix your problem for a small amount of money
Edit: it's very possible this plug works with other chargers and phones and still fails with the S2 charger. The reason for this is the different ways chargers convert the car's 12V DC into 5V DC. Some might work down to 7V input, some already **** up at 11.8V

I have the same problem with my GSII trying to charge it with my 12V Ipod adapter...
I just arrive from a short travel with my Citroën Xsara and i almost got lost cose the phone discharged all the time while using IGO on the phone...
I don't think this is car related because there are so many people with different cars having this problem... so... Samsung wants me to buy a new car to be able to use their phone in travels?

Hi guys, just thought I'd try to clear up a few of things:
1. All phones can use more power than they can draw. Note that the more apps you use, the more juice you draw depending on their features.
2. Not all CLAs are the same. Most modern devices will need 2amps, but the majority of CLAs on the market are 1 - 1.2amp units.
3. Your device will stop charging if it reaches a certain temperature, without giving you any further indication that it is too hot. This is a common scenario if you've got a phone on the dash giving guidance, with the sun rays beating a back. And yes this does mean dedicated satnav devices have a greater operational temperature range than phones, usually a 15-20 degree difference (celcius).
4. If the CLA is being tripped out due to poor isolation (a lot of cars suffer from this) it will also stop charging.
5. In general terms, the lower the battery level of the device, the more juice it pulls. This is why you may find you ha email no problems getting a small charge when you start with a battery at 85%, but your phone dies if the battery is 50% or less.
Hope that helps.

OK, I have no idea what the problem is. I have a Brodit active charger (the cig-plug version) for my Galaxy SII. It's not charging my phone AT ALL. There is no sound, nothing displayed on my phone when I connect it. I have the charger led (blue light) on, so I know it's working.
Things I have tried so far:
1. Asked for a replacement from Brodit. Got it, no difference.
2. Tried with a different car (I have a BMW, my wife a brand new Toyota Auris) - doesn't charge it either.
3. Tried a different no-name universal charger - it works perfectly well, the phone is charging as expected. Other things like the GPS device also work fine.
4. Tried a different kernel and ROM on my phone, still no success.
Any suggestions are welcome.

Thats strange, in the first place i thought a faulty micro-usb or charger. But you got it replaced so can't be the problem.
I have a brodit with charger too, but i use it in a different way, meaning i can remove my holder and unplug it without unplugging my charger. ( near my holder i have a small connector that i can unplug).
What i did is cutting the cable from the charger and i did put a male usb port on it ( regular male usb port) and i have a Belkin charger with a usb port, this charger deliver 1A charging current and charge my phone even when i use my navigation. ( with bluetooth and gps on).
Your phones micro-usb seems to be fine too because it charge with other brands of chargers.
Your BMW delivers enough power i guess at your cigarette lighter plug, because it doesn't charge at the Toyota either and both not delivering enough power would be coincidence.
Anyway mine works perfect the way i did it and if i can remember it worked too with my original plug attached too. ( though the original one doesn't provide enough power sometimes to keep it charged while using navigation).
The only thing i can think of is that there is some stress-pressure on your connection between phone and holder connection and that one pin isn't connected properly, with the universal charger you only plug the micro-usb plug in your phone and the micro-usb plug can adjust freely to your phones micro-usb port.
Try to wiggle a bit with your phone when in the holder and see if the power comes on. Or try to connect a little device on your holders micro-usb port ( if you have something small that charge over micro-usb) and see if that works.

Car Charger Spec Query

i am looking for a decent [working, cheap and quick charging] car charger.
I know I'll need at least a 1amp [right?] however i have seen a few that charger at 1amp and 2.1amp
is it going to ruin my battery if i use 2.1amp?
anyone found and goodies out there?
thanks

I second this request, i've got a few generic car chargers from older gear that i've tried with the galaxy nexus. So far they all come up as charging via usb, and so the phone loses power when the navigation/bluetooth/etc/etc is all on. I understand the power requirements, and looked into the data-cable soldering malarkey solution, but my soldering skills in the "fire hazard" class at best so i'd much rather an off the shelf solution.
I'd be very grateful if anyone could point out a car charger that they know/strongly suspect works fine.
Cheers

so the same car charger i've been using for my nexus one for navigation won't work with the GNex?

No, but it won't charge the battery faster either.

More amps is fine. Your phone will only pull what it needs, even if more amps are available.
Sent from my Galaxy Nexus using xda premium

Also be aware that even though some car chargers state they can supply >1A current, some phones (like my Nexus One and Galaxy Nexus) will not recognize it as a high speed charger.
Smartphones and other devices check to see if the data pins (D+ and D-) are shorted or have a specific resistance before activating high-speed mode since normal USB data specifications say that devices should only pull <500mA from the port.
I have this one: http://www.amazon.com/dp/B002IW79ZC/?tag=68656c7064757-20, which is supposed to supply 1A, but I when I plug my phone in with a normal USB micro cable, it says it's charging through "USB" vs "AC", where "AC" is the high-speed charging.
I've made a hacked cable adapter, though, which has the data pins shorted. When I use this with the car adapter, it charges at full speed. You should check to be sure that your phone is fully utilizing the charger by going into the Settings > Battery menu.

Hi all,
I thought I'd share how I've gotten on. There's a 2.1a charger that maplins sell that I thought might do it, but alas no - still comes up as "Charging(USB)". I know taFFer solved the problem with a little solder, and a lot of forum threads also suggest the same fix, but the last time I picked up a soldering iron actually ended with a trip to A&E (long, embarrassing, story) so I was still keen to find an off the shelf solution.
Anyway, after reading a lot more forums, I found a few different people recommending the same motorola charger. Amazon UK sell it, so I stuck in an order. Details below:
MOTOROLA P513 MICRO USB IN CAR CHARGER, £5.45*
http://www.amazon.co.uk/gp/product/B000S5Q9CA
*above item(s) sold by and shipped from Keep Talking
It arrived today and sure enough simply plugging it into the car results in it appearing as Charging(AC). I've not gone on a long enough drive to know about charging speed when gps/bluetooth/etc is all going, but if anyone else is after a cheap car charger that just works without hacking your own cable I think this is the one.
Cheers
***EDIT***
After criss-crossing the country over the xmas period i can tell you this charger is working fine for me. Even when using all the gps, bluetooth, screen on, etc that i can muster (while still driving straight!) the phone gains power and would often come out the car more charged than when it went in. The charger has one annoyance - they've built in a blue led to the charger which is lit up the whole time the thing is plugged in and thats kind of distracting, i don't really know what they were thinking with that, but otherwise i've no complaints.

For optimal charging, you need 1000mAh output. How much does this charger output?

In Car Charger - Recommendations?

For the past 2 years on my old Desire I was using a homebrew in car charger I put together myself that would happily provide 1A, but my new One X seems a little more power hungry than that and when in car mode it seems to discharge slowly even though it's still plugged in.
Can anybody recommend anything suited for the One X's huge power drain (homebrew or off the shelf, I don't mind) other than HTC's expensive official one? I was looking at the Belkin ones floating about but they still only provide 1A.
Thanks, Dave.

i bought the official ATT universal charger when i got my GS II in Oct and it should work with the One X. also, i think some car docks/mounts are active and have their own chargers, so you might not want both.

I'm using the official HTC Dual USB charger. Does the job nicely. and looks pretty good too. I just wish it was in white to match my One X

Did you try it with BT on, Sat Nav + music, screen on ?
I have the same issue as OP. Changed my 800 mah for a 1A but battery is still draining =(

Same problem here... 2x1A HTC Charger... Is there anyboby who tried Belkin 2A mini charger?... I am bit scared, because in my battery monitor history Ive never seen more than + 600mAh... Even when off on home charger... It seems to me, that phone woudlnt allow quick charging... :-(

I had my phone connected to:
Car Bluetooth,
Google Maps on screen,
Screen On,
Poweramp Playing in background via speaker, and
Phone connected to the official HTC Dual USB Car Charger.
No power issues whatsoever. I had it connected and charging for about 10 minutes.

I kind of solved this problem by setting ballanced power consumption policy in my Sygic mobile navigation and lower brightness setting. But still I am unable tu charge my phone while using WAZE (navigation and lot of HSDPA data trafic)...but for now its ok..most important for me is charging during navigation by sygic....
In the end problem is still there and should be solved...I think that its really not ok to charge battery only by 600mA while other phones are able to take 1000mA usually delivered by all chargers..

I just posted about this issue here:

it's not a problem of charging current, but of the phone battery overheating - it will just stop charging until it cools down (and if there's navi running it won't cool down, ever). I even tried a 2A charger - it will charge happily, but once I start Waze or Sygic it gets hot and starts to discharge again.
I think this is bad design because it should be able to run off the charger without battery in this case, but what it does is charge+discharge battery at the same time... either that or it just starts sipping from the charger when hot because it doesn't care if it's charging or just running from the charger....
Anyway, it has to be fixed.

same problem for me, but with some exception.
Im using Belkin mini car charger with 1A output. in car im turn on only GPS + 3g network. brightness set to 25%.
and with all of this settings battery slowly drain.
Also ive should say that battery not overheated through charging, but after 1% drained, phone says that "consumption is more that charger can give"...
Right now i think about other usb cable, not using original yet, may be inside it wire diameter too small to fit 1A.....

In fact i changed cable too... And it seems thats everything running ok even with waze on
And problem wasnt really overheating related since I have my car holder in front of air-condition grid... Its always under 30°C Best place for quadcore beast btw

I just use the data cable plugged into the USB adapter.
Keeps it topped nicely.

So not perfectly OK... I was driving long way again yesterday... With Sygic on, and my battery stuck at 71% didnt go down on charger, but didnt rise too.. In fact I started my trip at 80% Well it did the job in fact, but after 3hrs of driving it should be full as any other smartphone... :-\
There us something bad with charging policy in OneXs system... :-\

that's because it is using GPS (huge power hog), the screen is on (even bigger power hog) and then the CPU doing the calculations and rendering of the graphics, even with my desire hd it doesn't rise much when using sat nav. its a fact of life. the power consumed by the device is more than the charger can provide.
people have even reported that the mains charger isn't charging it quick enough whilst gaming for instance. (which doesn't surprise me)

Than it is fail of HTC... In fact my LGO2X (in most cases much worst than HTC) Handled it nicelly. HTC doesnt use potencial of charger. It takes only 600mA (top) while charger can deliver 1000mA.... And LG was able to use it....

I modified tiny generic usb car charger (5VDC 1A), so it allows faster charging. When opened up, D+ and D- pins were fed with some amount of electricity to allow iDevice charging, but I simply cut away traces leading to those pins and soldered them together. Phone reports "Charging (AC)". It really is standard method, but "surprisingly" Apple refused to follow standards and generic chargers do not work.

Hi,
i´m not really sure if this question is in the right place here.
After getting my HOX to replace my DHD i would like to know if i can use the DHD Car Charger (original HTC) for the HOX, too?
Thx...

Check out Avantek on Amazon. 2 out of its 5 ports are providing 2.4A, enough to charge your One X at full speed. An awesome product at an awesome price.
