I haven't come across a dual USB charger that will put 1A into an Android phone out of the box. If you don't mind buying a USB cable that has the data pins shorted (so the phone recognizes it as a dedicated charger), then the Griffin Powerjolt dual USB car charger (1A each port) is nice.

The Note will only charge at about 1/2A until you use cables with the data pins shorted together (I shorted the data pins inside the charger).
It looks nice (almost like in came with the car since it sits about flush with your dash). I can confirm it can put 1A into the Note (using Current Widget).

So it's not the car adapter that's not putting out 1A, it's the USB cable? If I were to use any car adapter + charging USB cable, my GNote would charge at full rate?
Also: how do I know if my USB cable is strictly charging or charging + data?

The charger has to be capable of putting out 1A or more for our Notes. If the voltage regulator inside the charger can't put out >=1A, then having the data pins shorted won't do any good. But if it can put out 1A+ and you don't have the data pins shorted, then the Note won't draw the full 1A. A lot of car chargers capable of 1A+ don't have the data pins shorted. I have read some people have luck with a OEM Motorola (1A out of the box) and I believe there is at least one Rocketfish charger (sold at Bestbuy) that gives 1A out of the box (although it only has one USB output). The problem is most chargers are meant to be compatible with iDevices and don't try to comply with the USB spec.
Most likely the data pins aren't shorted on any cable you have. Even if you have a charge only cable, it is probably just missing the data wires (not shorted). A few guys at work were buying cables off Ebay that were purposely made to have the data pins shorted. There are a few threads here on XDA (in the Note sections) that discuss various chargers and the need to short the data pins together.
Here is a discussion about a dual USB charger and charging Notes in general. http://forum.xda-developers.com/showthread.php?t=1720992

To the OP:
I just bought this off ebay: http://www.ebay.com/itm/ws/eBayISAPI.dll?ViewItem&item=170834845305&ssPageName=ADME:L:OU:CA:3160
It's a dual port, 2.1A and 1A output, I guess the device draws current as needed?

I bought a bluetooth FM transmitter, and it came with charging cables. I know they are charging cables because it doesn't work as data transfer. Do you think the pins are shorted, or the wires are absent? Any way I can check?

i used the voltage widget(as he mentioned) to check and see if it puts out 1am
just download/install the widget,plug into phone, and see what the widget says
if its 5,000 or less, then its running at only .5 amp
i see at least 9,000 (though it should be 10,000 or so) when 1amp is running

If you don't want to cut into a cable and solder, you can use:
http://www.amazon.com/Smart-Adapter...UTF8&colid=7NRVJS6JI4DY&coliid=I3TYTQBSNKZ4GK
With shipping, its kind of expensive. I ordered a few (shipping costs the same as for 1) and put one in the car because, without it, the cable I was using only charged at 500 ma.

thanks but i already tried that
it worked great for about a month (full 1amp) but now its conked out on me
so i was trying to go the shorted charger route this time, instead of an adapter
is there an instruction book somewhere that shows how to short cable?
