Actually, that's the wrong picture.
Here's the right picture showing 5.3 volts at 2.0 amps output.
http://www.wirelessground.com/samsun...ger-2-amp.html

The move to USB 3.0 only affects charge rates connected to a PC.

2.x is limited to 500mA while 3.x is 900mA I think.

Both standards use 5V, but 2A AC chargers often run a bit higher at 5.3V.
The chargers don't directly adhere to either USB spec and basically
trigger fast charge the same as before, by shorting out or putting a
fixed resistance between the data pins.

My old HP TouchPad USB 5.3V/2A charger with 2.0 cord charges my Note 3
just as fast as the Samsung 5.3V/2A adapter with USB 3.0 cord does.

If you look closely, you'll notice that the "USB 3.0" Samsung charger
doesn't actually have the extra 3.0 pins, it uses a 2.0 port. That's
because for pure charging devices the standard doesn't matter, only the
current and voltage rating and that it shorts the data pins.

As for the title question, I never myself could figure out the difference.
If you know, tell me because it makes no sense class 1 or class 2 except
from a driver perspective.

don't worry about it. it doesn't matter.

5.3v is noncompliant.

all adapters will be 5v (or sometimes 5.1v). it makes no difference.

originally, but the battery charging spec allows for more current.

no they don't.

5.3v is outside the usb spec.

then it's not compliant in more ways than one.

it's supposed to negotiate the power over the data pins.

it is not compliant with the usb spec.

don't use it with anything other than a note iii and any other samsung
product that it lists it will work with.

you won't and it makes no difference anyway.

You don't want one, it could fry some other device you plug into it,
just get a 5.0V 2.0A one and you'll be ok.

Duhhhh... and here's a picture showing a charger with *exactly* the same
product code (EP-TA10JWS) with the correct voltage (5.0v) in the product
label and text of the web page.
http://www.amazon.com/Samsung-Galaxy-Travel-Charger-EP-TA10JWS/dp/B00H8482KQ

Looks like there's a *mistake* in the wirelessground.com web page, it
should say 5.0v not 5.3v. So a 5.0v car charger would be the right
choice for you.

.... got the picture yet?

I can read it as 5.3 volts printed right on my charger!
So the only mistake is in the Amazon photos.

Hi,
It is not that super critical. As long as charger is good quality.
Also if you get wrong micro SD card, it won't work well. For example too
fast one some times gives trouble. Follow the manual. Get a brand name
like Samsung, Lexar....

It'll be fine.

The USB spec goes up to 5.25V. The extra 50mV won't fry anything.

In fact, the device probably won't even see it. If you're drawing 2A, you'd
lose 50mV by a 25milliohm resistance in the cable. Given that USB cables
contain hair-thicknesses of copper these days, that's not unlikely. I've
seen cables with 1 ohm resistance. In fact, to get a resistance as low as
25mohm you'd need about 0.75mm^2 of copper - that's roughly the thickness of
the cable that powers your desktop PC.

A lower current draw will have less voltage drop, but any way you look at it
what the device sees will be in spec. And the device would cope just fine
with 5.3V straight, the DC-DC converter will have a much bigger margin.

The nominal 5.3V is already out of spec, who knows what the tolerance is
on it, +/- 5% perhaps, so now it could be 300mV over, then someone
charges an unprotected e-cigarette from it and ...

Hmm. Hadn't heard of rechargeable electronic cigarettes. The ones i have
