big samm, usb devices dont operate like that. The device being charged (phone) regulates the charge rate up to the expected amperage - 500 ma is the normal usb spec and the max most computer ports can supply. To get above that the source/charger must be able to supply it and the phone needs to expect it. Either by assuming the source can supply it - if it cant like when hooked to a computer no harm done, it will just charge slower. Or by getting some signal from the source like my old phone did. The Note's stock charger is 1 amp so that is likely the max charge rate. Very unlikely it would be able to go faster with a 1.8 amp source. For starters that would be dumping 7 watts into a small battery...
How fast does this thing charge?

I have the Asus Sabertooth 990fx. It supports USB 3 fast charge. I'm not sure what the output it, but it will charge my phone from 5% to 100% in 3 hours 5 minuets. On the other hand charging from a standard usb 2.0 port it takes over 5 hours to charge.
If any of you have a computer with USB 3.0 support, and your bios supports fast charge you might check into it. It rivals the stock wall charger and you have access to your files while charging,

All I know is my phones charges faster with my 1.8amp chargers...for example today I was streaming a movie on Netflix via 3G in my car with a fast charger 2amp... my battery was at 53% 1h10 mins the phone was fully charged. With a regular Samsung car charger the phone would slowly discharge or slowly charge.

I have noticed the charging differences when using a usb cable thats not Samsung. When using my HTC wall charger and usb cable or my LG combo the charging takes longer than usual compared to samsungs. All three wall chargers specs are the same. When i use the Samsung cable on either chargers it would be a faster charge. Also tested belkin cable and generic one with the same results of the slow charge.
