That is correct, 900ma is the max, do you happen to know if all usb 3 equipped computers can deliver that though? I have one on my desktop that does, but a friend of mine has a laptop that I wonder about, I haven't checked it yet for him, but he thinks it's only outputting 500ma or so, maybe a hardware problem, but i'm curious if the output current should be 900ma to meet the standard to be advertised as 3.0
The Note 3 is limited to 2a,Even on my 8a charger.

It is fine. Even if the car only had a 10a fuse on the cigarette lighter, that is still 120W.
5v @ 2.4a is only 12W. Granted there is some loss going from 12v to 5v,but it should be well within limit

USB 3 has a MAXIMUM current rating of 900mA. The "standard" is still at 500mA, some at 750mA. If your computer is using a 'splitter bus' it's sharing power between all ports, maybe that's why you'll also notice a lower current output if you're powering different devices.
Oh, and actually there is the mythical USB Power Port since USB 2, which in theory would go up to 5A...but I still haven't seen computers with a port like this, only a few wall chargers.

WOW! You have an 8A charger??!! What for? hahaha talk about killing a fly with a cannon... It would be cool if the phone could stand it, though... Super fast charging! :O
My car has an outlet with a 2.5A fuse. Don't know why haha but it does. Better be safe than with a blown fuse
2.5a fuse is a bit small. I have used a power inverter to power my laptop and no issues. You can check the manual or service manual, it should indicate fuse size and location. Or there is sometimes a fuse card. Really no damage except you would need to replace the fuse. They make 4.8a car chargers so I am assuming most cars can take it.
2.4a 5v us only 1a at 12v

Ooooohhhh a multiport charger...yeah, that makes more sense. For a minute there I thought you had a single-port charger firing 8A lasersI have a 5 port 8a charger. It auto senses the power needed by each port. Supposedly it can provide 3a to chrome books. But the Note 3 won't accept more than 2a anyway

With the stock wall charger and cable, my Note 3 went from 5% to 80% in 1.25 hours (pretty fast!)
In contrast, trying to get it from 97% to 100% took far longer than 5 minutes like I assumed (if the rate was the same across the spectrum of charged-ness.

Are you saying that 1200ma from the note3 wall charger via its usb3 is faster than the galaxy s3 charger with its usb 2?
(I do realize that data transfer via usb 3.0 is much faster).
Mike
The note 3 power supply should be 2 amp, the "charger" is actually built in, you need to understand that the charging algorithm will change the charging current as the battery charges, battery temp, and percent of charge will affect charging rate, you will probably see Max charge rate between 20% and 80%, depending on temp, I believe it is showing you current charge rate, not maximum. And yes, 3.0 is much faster at data transfer, from a USB 3.0 port, the USB 3.0 cable makes NO difference if using a 2.0 port
Thanks for that.
@pcguys question really confused me. So it puts out (n3 charger) 2.0 A nominally as stated, but may read 1.2A during the process.
How can I put my hair back in?
