"Best" 2 Amp Car Charger?

Just looking for everyone's opinions.
What is the "best" 2 Amp Car Charger that you have personal experience with?
I see a ton on eBay and Amazon, but confused as to what everyone prefers.
Look forward to your suggestions...

Either really.
Just looking for a fast charge device for the car (12v).
Any info would be appreciated...

You don't have to get a 2 amp charger if it's just for your phone. It will only draw about 1 amp at most.

I got the Verizon 2amp charger. Thing works great!
Sent from my locked bootloader Verizon GSIII.

I believe the one T-Mobile sells is 2.1A, and has an additional USB port so you can charge 2 devices at 1A simultaneously

T-Mobile actually sells a 3amp now.

I wish I could find a 3 amp, that did 5v to 15v so I could charge my Transformer Prime and another device...

I want that charger, but not at the $40 price tag.

I bought 2 refurbished at&t chargers ( micro usb) on ebay for $5 from one of those daily deals offers. Been using them about 6 months now, rock solid. Charges most phones faster (imo).

I have the Kensington K33497US PowerBolt Duo in both of my cars as well as on my ZX14. It has 2 USB outlets, a 1 amp and a 2.1 amp. On trips it has no problem keeping our my phone, my wife's phone and/or wife's iPad at full charge. Note: this is with both devices in use (display on and running apps)...
Here is a link to the product on Amazon: Kensington K33497US PowerBolt Duo

That sounds like a good option for you (albeit expensive), since it sounds like you were using an apple device (the iPad) on the 2.1amp outlet and an Android device on the 1 amp outlet... but it seems that this particular charger is not the best choice for non-apple devices, based on this review. This guy sounds pretty knowledgeable on the subject, and reviewed a few different similar products too, so it's some good reading.
To summarize his reviews across some of the different products he reviewed, it seems as if he has yet to find a 2.1amp/1amp combination charger that (a) supports Android devices out of the box AND (b) can deliver the full 3.1amps at once. He seems to recommend this one (with a little modification) or this one.
Of those two, it seems like latter is a better all-around choice, especially for people who own a mix of apple and non-apple devices. From his review:
"The 2 Amp port appears to be using the Apple protocol for USB power, so that port will only provide 0.5 Amps to most other devices. The upside of this is the 1 Amp port somewhat over delivers, and can source 2 Amps if nothing else is connected and 1.5 Amps if the 2 Amp port is sourcing 0.5 Amps for a non-Apple device. Thus this product can support one-high power non-Apple device (in the 1 Amp port) and one lower power device (in the 2 Amp port)."

So, my advice is the following:
Understand the differences between the Apple protocol and the non-apple protocol (or at least understand that there is a difference)
Know what types of devices you will use with the charger
Know what protocol the charger uses, and make sure it aligns well with your planned usage
Find out whether the 2.1amp and 1amp ports will work to the full 3.1 together, or if it's capped at 2.1
Read the reviews
But, as I said, that last like I posed above seems to be a good all-around charger at a good price ($9.99 + prime shipping)

On a related note... does anyone know of an app that one can use to easily see how much amperage the phone is getting through the usb port?

Battery Monitor Widget should do what you need. It displays the current current and charge (yes, I made that sound redundant on purpose) for the battery.

Hmmmm... I just downloaded it just seems to give the charge levels, not the actual real-time current.
I get stuff like:
32.7degC / 4122mV
1050/1500mAh

Am I missing something?
Also, as I'm thinking about this more, it seems like ANY app would really only be able to give me NET current, that is... (input)-(amount being used). That wouldn't really allow me to find out how much the charger is putting out, right?

Thank you for all the input.
I stumbled across this Anker 3A charger on Amazon
http://www.amazon.com/Anker-Heavy-Duty-High-Output-Superfast-Charger/dp/B00809LJAI/ref=sr_1_sc_2?s=wireless&ie=UTF8&qid=1342121296&sr=1-2-spell&keywords=car+caherger+3a
Seems to fit the bill, and has preaty good reviews.
Thoughts?

Yes I believe for the galaxy s3 it only shows the "estimated" amp draw of the device, which is given by that expression.

After reading the OP on this thread http://forum.xda-developers.com/showthread.php?t=1754102 the phone will draw either 500ma or 750ma. The type of charge is determined by how the charger handles pins for the USB cable. I wonder if some of the chargers that say they provide 1+ amps have the USB port setup in this manner so that the S3 thinks it's in AC charge mode.

He was talking more about his SGS2 I think. The SGS3 is 750mA or 1A I think.

The 500mA is inline with what I've previously heard about the amount of current available over a single USB port. I re-read his post and it does sound like he's making the assumption that the S2 and S3 are the same.

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.

[Q] New Android Convert From Crapple. Please Help Me Find Chargers!!!

So no matter where I look, I cannot find good chargers for my GN2. Here I was thinking that I'd be able to use my 10+ white brick crapple charging blocks at 1A and here my awesome GN2 uses a 2A.
Now I understand that Apple swayed away from yet another standard and the pins need to be shorted in almost all car chargers in order for anything other than an apple device to accept an AC charge. Awesome.
I'm very happy that this huge battery needs a 2A charger but I'm back at square one. I need chargers... I need a lot. Please somebody point me in the right direction on what every android peep is doing to charge their phones on fast chargers... I am mostly in need of a car charger. Every forum I look at, the thread ends with no definitive answer...
Much thanks.

This is the charger that I use for my car charging needs. Ive had it for a couple if years and it has worked flawlessly. It also has an extra usb port for charging a 2nd device. I havent had any quality issues with mine like some of the reviewers have claimed. This works brilliantly with my Note 2. It can output up to 4 amps and charges 2 Note 2's with max screen brightness and GPS with no problem.

[Q] USB Cables for Note II

Can anyone point me in the direction of cables to get that will actually charge up my Note II using 2.0A? The cables I've found will at most only charge at 1.0 A and I was wondering if anyone had any actual cables (like the OEM that came with the Note II) that they could recommend?
I don't want to short out the cables myself.
Also wondering if there's some sort of App that would allow me to force my phone to charge as though it was always on AC power. I'm not rooted.
Any info would be great, thanks.

Watch the reviews of these products but I have several blackberry usb cables that provide better results for me personally when charging. However they arent good when it comes to tramsfereing files at fast speeds.
Now that samsung one is more of hit and miss. However if you have the charger that came with your phone just buy a usb cable is all.

Yes I charge at 2 amps. It's the actual charger/brick/plug not the cable that pumps the amps. Not only do I charge at 2 amps but I also get good data speeds. Monoprice sells great stuff at great prices. If you can find REAL OEM equipment at a good price I would suggest you get it but if not give them a try.

i use monoprice cables as well. never had any issues.

That's not exactly true. The cable plays a part in how much of the current gets sent to the phone. That's why a lot of the times you have to short the cable so that it reads as a charger and not a data plug.

Well I've been using smartphones for over 10 years and I've never had to short a cable to get it to read as anything other than what it was. Just my guess, if you have to purposely short a cable to get it to work right, you probably have the wrong cable. I use these cables all the time and my phone charges just fine with no shorting. Now I am using the brick that came with my Note II and I use the brick that came with my Galaxy Tab 2 7 when at work, which also charges at 2 amps. The reason why I buy so many of them is because the cord is a lot heavier than the OEM ones and the added weight sometimes makes the connector loose. But Monoprice has a lifetime warranty on all their products and a easy return policy so if a couple do fail over time it costs you nothing to get a replacement.

Yeah, there are several threads about this as most USB cables are designed to read as data cables and therefore do not give you the maximum current for charging. Most people short out two pins to make it read as a charging cable. That's why I posted the thread looking for cables that are already designed as charging cables and not data cables. They're pretty difficult to sort through. Thanks for the links.

In need of a good car charger

The one I got barely charges the phone, it charges really really slow, any of you guys know of a good brand?
also looking for a good efficient wireless charger what do you guys think?
Thanks in advance.

Been using this one for a couple years, dual 1 amp ports and it's very low profile. Sticks out of the power socket just a few millimeters. Charges as fast as most standard USB chargers.
