Car charger that charges at wall charger speeds?

Any car chargers that anyone could point me to that charges as fast as a wall charger?
As it is right now, unless I have my screen off and no apps running it drains faster than the charger can put juice into it...
I'm just using an el-cheap-o aftermarket car charger.
Thanks!

What I use is a cig to usb plug (cost me 10 bucks at walmart). Then I bring the cord from home that came with my phone and plug that into the USB to cig thingy. Works like a charm, I haven't noticed it charging slower than when at home.

i bought one from t-mobile... its about $29 but its worth the price. I get charge speeds btw 850ma and 950ma when on idle

i have the oem cig to usb charger from Samsung i purchased it at best buy with a gift card lol, when i first got my galaxy tablet.

Just get any standard microusb charger rated at 1a (or 1000mAh ). I'm betting your elcheapo is .5a (500mAh).

I finally got around to ordering that Motorola charger on Amazon - works just how I wanted it to - thanks so much!

our device requires an official samsung charger to charge at full ac speed. there was an article on the xda front page last week about how to mod your charger to be recognized as official.

All I know is that now I can run my GPS with the screen on and still move UP in battery - before it would drain faster than the car charger would charge, so, I'm happy with what I have now.

Actually the problem is that some of the car chargers are not at 1amp output but less .75 or .85. Thats why your not really seeing an increase. The stock charger is at 1amp. I know AllGamer likes to use the Blackberry ones (which i believe are 1.5amps) Correct me if im wrong AllGamer.
So just look for 1 amp car chargers the cable doesnt matter itll hold whatever you attach it to.

So, no matter wht brand charger you have as long as you connect the two middle pins you will get full charge as long as the charger can put out 1000ma?
I really need a good charger for the car, right now i use a blackberry charger at work an it charges pretty fast. But i need to know how do i find the currect charge rate of a charger. Is there an app for that?

Get tmobiles car charger. Its faster than any others I've tried.

As I remember those chargers needed the center pins shorted to be recognized as AC.

This charger doesn't keep up. I have one. It will still drain faster than it charges if you're running a GPS app with the screen on.

Does anyone have an experience with this charger from MONOPRICE
http://www.monoprice.com/products/p..._id=1082603&p_id=8858&seq=1&format=4#feedback
I need a great car charger and really dont want to spend to much money on it. Furthermore, if I am getting a 1+amp charger, as long as i am using the stock samsung charging cable then it shouldnt matter if the charger itself has D- and D+ shorted right?
Im assuming this is something standard on all usb CHARGING cables as appose to data cables.?

You want a good reliable charger at eBay pricing..... spend the money 1 time and be done with it. You could've already gotten the T-Mobile one and been done with it.

For those of you buying the USB 12V Cigarette adapters read this.
Basically if you use a data sync cord with one of those adapters, unless it shorts the 2 data pins together internally (probably not) the phone is going to think it's plugged into a computer and only charge at 500ma (max output for a computer USB port). The write up above explains to short the 2 data cables together (this is done internally with the main AC charger head) back towards the phone so it will charge at 1amp instead of 500ma.
You can buy this cable and just modify it as described. I bought this USB adapter so I could charge 2 things at once.

Let me get this clear.
All i need to look for when it is charging is AC mode. As long as it says that, it doesnt matter what i have or have not done to the cables, AC mode is AC mode.
The charger i am looking at getting is 2.1 amp (because it has a spare usb port...so 1amp per line) and when i plug it in and it says AC MODE then its good to go right.
I just bought a TMOBILE offical charger that shows AC MODE, so when it MONOPRICE charger arrives i can compare. If it doesnt work its another 5 bucks, if it does i can take the tmo one back.
But again i am just wondering are there any caveats to AC MODE, or is it that once AC mode shows that is all that matters.

Efficient enough car charger.

Hi guys.
I have a problem finding good car charger for my phone while in car.
I either use sygic sat nav or Google maps but on top of that I stream music either via Google music or di.fm app.
Problem starts when I start streaming. My battery slowly drops down about 1% per 15min. I've tried various car chargers that have either 1amp, 2.1 amp and even dual 3.5amp they don't do the job. Only my HTC 1amp charger manages to hold the charge but it doesn't charge on top of that.
Any ideas and suggestions?

I bought the car charger from Amazon HERE earlier this year and it has worked out awesome. I usually leave it in my car but also makes a great wall charger for when you need it in a pinch and didnt bring your own. Its 17 (I got free shipping since I have Amazon Prime) and well worth it since I dont think I ever have to buy another car charger again for any device I own. Even charges my tablet.

Genuine Motorola rapid car charger, simply the best. Charges like a wall charger, seriously, phone says it's plugged into AC power

I use a 1A HTC charger and never had any issues. Are you sure your cigarette lighter is working properly? It sounds like all of these chargers you've tried are charging at less than 1A.

I think 1 amp is about all it will do. It will have a hard time keeping up if you are using it a lot. I have the htc car charger and it seems to keep up for me but actually getting a decent charge while using it will be hard.

not all 1a chargers actually charge at 1a. it depends on if the two middle pins are shorted together or not.
this charger is cheap as hell - 3 bucks - and charges at a full 1a. i use it and it works perfectly.

I noticed this too, using a Kensington USB charger in the car. On my drive out to Phoenix, I noticed that having Navigation running while plugged in caused the battery to drain.
I also noticed that running Torque sucks the battery down as well. I stopped at a gas station that had a ton of gadgets, so I bought another off-brand USB adapter that stated its output is 1.5A. I also picked up the OEM extended battery at a VZW store while out there. It doesn't drain as fast now, but it does still drain a bit.

Motorola
Absolutely go for the motorola charger. I use it everytime in car, it's a 1A charger, has a nice blue light and can charge your phone even when using navigation.
And on top of that it's also cheap. I bought it in boundle with a motorola wall charger @ 10€.

is it this one guys http://www.ebay.com/itm/OEM-Motorol...846874?pt=PDA_Accessories&hash=item2a1ea6619a

Make shift cable.
If you're super cheap and/or like to DIY, I was able to get my Galaxy Nexus to recognize any USB charger as AC by cutting a USB extension cable in half. I then soldered/twisted the green and white wires within the USB cable together and then I soldered the red to red and black to black. By putting the modified USB extension in between the charger and a USB to Micro USB cable it will force the phone to recognize the charger as AC instead of USB. I sealed up my adapter with some White and Green heat-shrink tubing I had lying around so it would be easy to identify. Same thing can be done to a USB to Micro-USB cable if you want.

Best car charger?

So which car charger do you guys recommend for the S3 that has AC charging enabled?

rapid charger at up to 1A. best car charger on the market, especially for the price.

Does anyone know where to get a USB coil cord that would fit into this?

Personally I have the wireless charging mod done and in my car use a Palm Pre Touchstone as a charger. It looks incredibly good and clean.
It is NOT the fastest charger however (only about 500mah charge rate).
If you want the fastest charging, I would get one of the ipad car chargers. 2.1 amps of charge power will more than juice your phone.
Personally, I recommend the Griffin one: http://www.ebay.com/itm/GRIFFIN-POW...ccessories&hash=item3a779d867b#ht_2277wt_1166
You may be able to find it cheaper somewhere.

I've read in a few places that rapid charging isn't good for our batteries. Any truth to that?

The phone will only take 1 amp regardless of the charger being 2 amps. Buy a well built one and you'll be fine, they all charge the same provided they are 1 amp.

+1 for this, I've been using this for ALL of my Android phones.

A lot of people seem to recommend that Motorola charger in these forums for various devices. I think I'm going to order one.

The Moto car charger has decent reviews on Amazon.
There any others recommendations of car chargers ?

Be careful. Bought a cheap one and found it sent dirty power that introduced noise into the audio out on my car dock.

I cant find the link but there is a 3 amp chager in the tmobile store its expensive but worth it.. a 15 minute drive gave me a 23% boost

I bought that bad boy. The build quality is awesome. You can twist off the cap and replace the fuse if it's blown. Unlike some other chargers you have to pry it out and possibly break it. This one can charge up to 3.1 amp on one usb port for tablets and 1.0 amp on the other port cell phones. Yes by default my phone was charging in AC mode with my sam captivate. Then i decided to modify it from one of users tip on there for permanent AC charging. No issues so far.

OEM charger output vs. high output car charger

IIRC the stock wall charger is rated at 1.8Ah. But, what is the phone's actual draw? Does it ever get up there near 1.8mAh?
I'm just trying to figure out if a car charger with "only 1000mA" will be sufficient. I'm guessing that the OEM wall charger is rated well above whatever the phone might ask for, but as to how much, I don't know.
I'm actually looking at these two right now as they both seem to give a pretty high output for both Android and Apple devices.

My experience with other phones is that the phone draws exactly what the stock charger gives it. I'd imagine it's the same with this one. 3140mah is a lot of battery to charge.

I'd agree. I charged it the first couple days using the OGP wall charger and USB cable from my Nexus 4. It took all night. Switched the cable with the one in the box, and it charges in like an hour!

I have a 2.1a car charger, and the OGPro charges in exactly the same amount of time as the stock wall charger.
Oddly, it charges slower from my 2a Note II charger.

Im looking at all of the chargers from Anker on Amazon. It seems they have the best positive reviews of anything I've seen. Although the 3.6 watt (white unit with either 2 usb ports or one port and a micro usb cable) unit is newer than the 3.1 (black heavy duty), the black unit can give the full 3.1 watts to either port or split it amongst the two ports. And according to Anker, either port will work for Apple or android. They suggested i get the newer (white) unit, but i want to have the full 3.1 watts available to a single port for future h higher powered devices.

I'll have to check those out. I've been looking at this one, which has good reviews on it.

My concern with that one is that it gives a total of 2.1A. So if you charge your OGP using one usb port, there's only 0.3A left for the other port. The disclaimer at the end of the description says that if you are charging an iPad to not use the second port. I'm guessing that warning would also apply too us with the high draw OGP. It also states that the blue light gets even brighter in the dark. You might need to cover the led if it's too bright,but that's a personal taste thing,and it might not actually be that intrusive. Lastly, do you have enough room in your vehicle to rest both your phone, and the head of the charging device? I have a dual outlet 12v supplier in my car, but i bought one that has no cord. The two outlets are rigidly mounted right at the end of the cigarette lighter plug.

I bought a Griffin Powerjolt single USB at Walmart. It only charges at full speed using the OGPro's stock cable. Any other cable is slower, and the cable from my old S2 gives me a "Slow Charging" notification.
Anyway, this charger is just a stop-gap. I'm going to be hard wiring two USB plugs into my truck's 12v system (with some 5v regulators and an Add-a-Circuit).

I was looking at the 3.6A charger, here's the link on amazon.
As I expected, one port is for Apple and one for Android. This is very irritating because I need to charge my OGP while my fiance charges her OG at the same time on trips.
Can our OGP charge at full speed on the Apple port?
Edit: I just read that the kernal in Android 4.2 fixes this issue so we can charge in any USB charger, including apple chargers. I'm guessing LG devices still on 4.1 won't benefit from this update.

Shouldn't going to Settings > PC Connection > USB Connection Type and then setting it to "Charge only" force the device to see any cable as a charge only cable thus making it charge faster?

As per Anker, the Apple port will charge Android at full speed. I have not verified this myself as I have not gotten mine yet, but that's what I'm told, and expect. I'm waiting for their wall charger to come back in stock as the shipping will be free if l order both.

I ordered the black 3.6v version. I'll get it Monday or Tuesday since I have Prime.

Old RAZR car charger work with N5?

Everyone,
This might be a dumb question to some, but I'm a bit paranoid about harming my shiny new N5!
I have an "old" car charger from my Droid RAZR, and I was curious if would harm my new N5 to use it. I occasionally take long-ish trips to visit in laws and stuff, and on Sprint's network especially, roaming can suck up battery like nobody's business.
The car charger I have is rated at 5.1v and 850mA, but I noticed that the N5s wall charger is rated at 5V and 1200mA. Will this damage my N5 or battery life over the long term or anything like that?
I can't post links yet, but the Amazon product code is B005LFXBLE, if anyone is curious about which item I own.
Thanks in advance, experts!

The OG RAZR Charger will work fine but like others said any 1A+ 5V car charger will work fine just be careful of quality some cheap ones will cause issues.
There are some car chargers endorsed by others listed in this forum. (I use a $10 2 port charger by Onn I picked up from Wal-Mart that works fine)
