Please sell me your car charger

I have been trying to get hold of a working car charger for the Universal that would charge the phone while it is running navigational programs but to no avail.
If anyone has any for sale, do let me know.

The car charger costs barely $5 in china and on ebay. It can be purchased from anywhere. I use the car charger that i got with my Holux GPS reciever. I have a lot of car chargers. This is how they work. You plug in your USB cord into the car charger and the car charger goes into the cigarette lighter in the car. I am not selling mine. Go get one from ebay. Just search on ebay for USB car charger.

I have done so and the thing, its either I'm having bad luck with them or there's something wrong with my phone. The best I ever got was that it charged the phone when it was OFF but when I switched it on, the charge disappears.
I tried using my GPS's car charger and another USB Car Charger as well but they both do not work and I do not know why.
I have spent so much searching for the right car charger which is why I am so desperate now just to get a second hand one that would definitely work.

I think you'll find this has been discussed here before, try searching.
FYI, I used the charger from my Holux GPS, and whilst it works, it dosn't charge whilst using TomTom. If you try a long trip with this setup, you will find that the battery charge drops. This charger is good only for topping up the Uni whilst not in use. I use the genuine iMate charger and this does run TT and charge at the same time. You need the higher amperage of the iMate charger.

Nope, my car charger works fine in charging the Universal while in use and turned off. It just charges a bit slower while in use and thats quite an obious reason.
Only thing to consider is how much the output levels are of the car charger.

Thanks for your input guys
I have done my research on the car chargers and from my understanding, the only reason could be the shorting of pins 4 and 5, or something along those lines. Other than that, I have tried out various models of chargers and they do not work.
For those who say you need a higher output, I have tried those rated at 1000mAh which is that charger output for the wall unit. This charger connects to the USB cable yet even when I tried a couple of types of USB cables, it still did not charge the phone.
I also used a lower output of 850mAh and it worked fine with the cables tested abouve, so it shows the cable had no problem. But it could only charge the Universal when the phone was turned off. When switched on, the phone does not even charge, not even in the least bit and I am not sure why. Surely 850mAh is more than enough to get it charging while on the navigational (TomTom) programs because when I connect my Universal to my laptop to charge, I am still able to run TomTom and that charge is only rated at 500mAh.
Thus you can see why I am so frustrated with all these charges. If any of you are able to point me in the direction of getting an original chrager online, I would be more than grateful for your help and guidance. I also wouldn't mind buying a third-party charger as long as it works perfectly with the phone when running nagivational programs.

This is the one i have. works brilliantly, charges universal and BT GPS reciever and lets me use my copilot navigation software.

Well, I can only guess the 1000mAh you tried may have been defective???
My car charger is the iMate genuine car charger. This rated at 1000mAh and works great. It charges and runs TT6 no problem. (well, that was untill it packed up the other night so I'm sending back under warranty) But it did work great.

Poundland have a USB car adapter that works perfectly with your USB lead to charge the Exec - works fine on mine!

re: car charging problems
just one thing to ask: are you a smoker?
I only say this because i use a usb car charger and it only charges faster than it drains if you are careful to blow/clean all the fag ash out of the socket in the car to get a good connection. Otherwise the charging led sometimes comes on but cant supply enough power to charge quicker than my universal drains its battery

I never get ash in there. Its impossible to get ash in there unless you really want it there. You are supposed to use the knob and not stick your cig in there. lol

I have used a Belkin one, one that I bought for an iPod that has a standard USB socket you can plug any cable into, and a cheap ebay one.
They all work, BUT.. you have to plug them in when the device is off. Once the charge light comes on, you can turn it on, and it will charge, although slowly.
If you plug it in while the device is on, it will not start charging.
I don't know why this is, but considering it's the same on all 3 chargers, and I have seen people complaining about this on the Universal a few times, I think it's just the way things are.

Yup because at first i was wondering too why my device isnt charging. Actually the charge light on my GPS came on quicker than the Universal.lol... i had to wait for a few moments and kept trying till the universal began charging. So yeah you gotta wait with the universal shut off.

I have not bothered reading all the replies but the problem with most car chargers is the AMPS, the voltage is right @ 5 volts but the amps is usually 0.5. Ideally the universal needs 1 or 2 amps, the new tomtom standalone units use 2 Amp USB car chargers and are a direct fit for our universals !!! isnt that convenient.

I don't have a charger as such but I use - strangely enough - a sony psp usb cord that goes through a USB cigarette adapter picked up from a poundshop here in UK ( a shop that sells lots of cheap gadgetry - for the non british of you )that also has a connector that is exactly what is needed for my fortuna bluetooth . it works fine . I realise that it does not recharge the phone but keeps it charged . I've not tried the usb to usb mini through the usb lighter adapter though . I guess that the trick its to have a charged universal before you leave on a trip .

I found I was having trouble charging my Universal with a USB adaptor in the car. The "charging" light would only come in if the phone was off, and while it would stay on when the phone turned on, it would not actually be charging and the damned thing would eventually run out of charge (I drive lots).
I eventually realised that if I turned the screen brightness down to it's lowest illumination whilst charging it worked fine. Obviously not much power comes out of the socket...
Now my battery has packed up due to another issue, but turn the screen down and it should be fine.

Voltage Regulator 5v / 2a /
I have read with interest all the comments and solution here and thought it might help to add mine what I have made and fitted to all my vehicles is a mini USB power supply, simply cut the pc plug from a mini USB lead and add one UA 78S05
VOLTAGE REGULATOR 5V / 2A /
http://www.donberg.ie/descript/u/ua78s05.htm
Connect the input leg to 12 v dc bolt the regulator to a GOOD earth/heat sink (car body) and off you go up to 2 amps @5v BUT DO TEST WITH VOLT METER BEFORE CONNECTING PPC

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.
ALexander

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.

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?

[Q] Standard Car charger vs USB car charger

I recently sold my old Toyota Rav4 which only had a standard cigarette lighter car charger. I used a cheap charger I've had since my old Blackberry Tour to charge my ET4G. I work on the road a lot and used the car charger a lot for about the last 10 months til my phone started dying on me. Sprint store tested the phone and said the battery was slightly swollen and definitely showed signs of being damaged which in turn damaged the terminals on the phone causing constant reboots. I paid $35 to have Sprint/Samsung replace the phone as it was less than a yr old and under warranty.
I now have a new car and new ET4G. New car has USB port under the radio as well as 2 standard car charging ports. I've done several searches and read several threads about different voltages and which ones actually charge phones and tablets etc but none have answered my question. The question is is USB charging any safer than standard car charger? I've been told by a friend that fluctuations in the cars battery can send different amounts of charge to the phone and damage it over time. Both methods charge my phone so I don't care which one I use though I'd rather use USB as my USB cord is just 1.5 feet long (perfect length to reach my phone mount).
For some reason they actually gave me a new ET4G not a refurb and it works great. I don't want to damage the battery on this one and would like to keep it alive and sell it when I upgrade phones around December. That's only a few months away but I'd like to know I'm not damaging the battery in the mean time. Any input would be great. Thanks in advance and sorry for the lengthy write up.

Anyone with any input? Anyone use USB to micro USB in their cars?

Don't know if the new car is also a Toyota but here goes...
04 and 10 Toyotas - tried a cheapo MicroUSB charger and the voltage actually drained the battery! So I bought a $10 lighter to USB port charger, plugged in the cable and charges like a champ!
It really depends on how much power they're pushing through the USB port and whether the E4GT can regulate it. I'm finding it to work great - and MTP mode should give you access to the music on the head unit. (Again, *if* it's a newer Toyota...)

Most radios and internal usb ports will be 500ma (same as a standard computer usb port). That is only enough to charge the phone when it is sleeping. Just snag a $10 adapter that puts out 1a.

Thank you both. I just drove 2 hours with Bluetooth on and GPS running while connected to USB. Battery drained 8% which isn't much so it wasn't strong enough to charge it but slowed down drain.
The new car is a 2013 Hyundai Elantra GT (It's a new model to Hyundai). The cigarette charger doesn't seem to over heat the phone like my Toyota did. I'll ask Hyundai how much charge the cigarette lighter port puts out I guess.
Sent from my SPH-D710 using xda app-developers app

I highly recommend the OEM Motorola car charger. Got mine on Amazon for $6. It was the only charger that would work on my old phone because it had voltage control. Any generic charger would only drain my battery while still displaying the charging animation.

I highly recommend the OEM Motorola car charger. Got mine on Amazon for $6. It was the only charger that would work on my old phone because it had voltage control. Any generic charger would only drain my battery while still displaying the charging animation.

Sweet, I'll take a look at it. I heard back from Hyundai and the guy said he has no documentation on it yet since its a new model but if I wanted to swing by he could test it real quick and let me know. Today was hot as hell. I got in the car and blasted the AC. Put the phone on the USB charger and after about 10 minutes I got a warning on my screen saying phone is too hot and charging has stopped. I didn't even have GPS on or anything. I quickly unplugged the phone and it was fine after that. How can the USB overheat the phone when it can't even charge it while I run GPS and Bluetooth? I wasn't too happy. I used a brand new USB to micro USB cord from Monoprice (5 pin if that makes a difference).

Car install Questions

Hello XDA members and fellow nexus 7 owners!
After reading these forums for months or even years i decided to get a Nexus 7 2013 myself. It took me a long time since they are not being sold that much in the Netherlands.
Upcoming Tuesday it will be shipped and i can not wait to be able and install it in the car.
Setup? ---- I am going to run the nexus 7 together with my 1 din car radio. Which means i wont be using a dac or anything else just spotify over bluetooth to the car stereo and that is it.
The only addition i would like to have is a backup cam since i am terrible at parking... go ask my rear bumper he will show it.
Now i know about rooting and all that but i would like to know which camera to buy. I have seen people using a easycap and i can get one on ebay. But which setup are you running or do you recommend me to get? Any ebay or aliexpress links will be appreciated. This way i can buy the stuff and know it will surely work.
And yeah i been searching through forum and reddit. But everyone is using a different setup of rom and hardware which just makes it confusing. I already have the usb otg cable and thats basically it.
Thanks in advance!

Prepare for a world of hurt. You'd need to find a real UVC adapter then start the app each time you want to back up.
UVC and EasyCap are terrible for start up times, 4 seconds to show on mine. Oh, EasyCap drivers aren't in the system by default, the need to be installed and loaded on boot with a script.
The latest thing on the Timur's forum was to use a USB camera. Problem with that for me was they're housing are terrible. not suited for cars at all.

thanks alot for your reply! i decided not to do the cam install as i been reading alot of issues indeed! My nexus 7 was delivered today. Now im just having issues with charging in car and how to do that. I think the 2.1a car charger i have should be able to keep it at 100. Since it keeps my phone galaxy s8+ at 100 using navigation spotify and such

Prepare for a world o... I already said that didn't I?
Are you using this in car only? The problem is the tablet can use power faster than it can charge, especially when using navigation.
Mine was fine for about a year then it started not keeping a charge. I did the battery removal mod and couldn't be happier.

I just dont understand how that battery removal mod works. Or what i should do to achieve the same thing. Not really a genius with eletrical work unless i see pictures of everything then it is easy ofcourse.
Seems like no one in holland has this lmao. O yeah and here its only 1 week hot outside like 30C max so i dont know if its needed.

It's not so much a heat thing as the battery will drain in use. It simply can't charge fast enough. I had the problem even through winter.
I guess I left out the part where I should've mentioned to use it with the battery and see if there's an issue.
There's info but not great info on the removal mod. It's straight forward but it need "large" wiring and a power supply over 1.8amps.
Hook everything up, without installing right away, and get a feel for it. All the little details will show itself.

Again you are so right! I have had the car install now some days and it drains more than it charges xD the gps is also bad which sucks. But using waze it goes into -200 mA and with only spotify on and no navigation to +150 mA. I will really need to check that battery removal mod. How did you do that? do you have some old pics laying around or a scheme? I even tested 2 new car chargers i bought 24w 4.8a and neither that keeps it charging pfft. And this with medium settings on screen brightness

What do you mean "GPS sucks?" As it doesn't lock on satellites, or it just drains the battery more?
The battery removal mod is pretty straight forward.
You'll need an adjustable 12v power supply that puts out over 2 amps adjusted to 4.4v. This is the one I have: https://www.amazon.com/gp/product/B00C0KL1OM/ref=oh_aui_search_detailpage?ie=UTF8&psc=1
Find an old power supply you have lying around, like for a router, and use those wires. If they're too thin the tablet will be unstable.
I'd probably look for an extra battery online in case you want to revert. And this is the part photos are needed.
I'm having problems finding the ones I saw when I did it. I'll look some more and if I can't find them I'mm take some myself the weekend.
It just involves separating the battery from it's controller and soldering the voltage regulator in place of the battery. The ground has to connected to one of the tiny black wires at the controllers connector and it's done.
I wired the voltage regulator into my radio's constant power supply and I still use a charger to the micro USB to turn it on and off.
-edit: oh yeah. here's the video from the guy that discovered the mod: https://www.youtube.com/watch?v=9N2Bh4fI8Bo

Thanks again for your reply. I just checked that video it seems doable.
With gps i ment the lock on satellites. I found someone who was using a kind of re radiator if that is what it is called and im thinking of buying one.
I think i will just start soldering and doing that battery removal trick. Do you think i could do it and just plug it into a anker car charger? It is 5v 2.4a each slot. This is the one https://www.anker.com/products/variant/powerdrive-2-ports/A2310012
Or should i go for a dc to dc regulator as you have? I have currently 3 of those car chargers laying around all different brands but same watts.

Here's a photo someone else posted just the other day. The second wire is ran better than I did: https://forum.xda-developers.com/showpost.php?p=76554736&postcount=464
I use a 5v supply when I work on my tablet in the house, but I've heard 5v could cause problems with the tablet not recognizing when power is connected to the micro usb.
My GPS was terrible at first. Long lock times, if it locked, would drop satellites spontaneously then come right back. I even bought an external USB receiver. Then it just started working.

I guess there is just 1 way to find out if the car charger works hehehe i will give it a shot see what i manage to do. Still looking for a housing or anything to mount the tablet in for my car a renault megane II from 2003. Seems like i will have to mold and fiberglass it.
