I want to buy a 32GB memory card for my new Samsung Galaxy Note 3
and I see "Type 1 class 10" and "Type 2 class 10".

Googling, I see they use the word "type" for card types such as
compact flash and SD, etc., but no good explanation of the difference
between card types at any one class.

Also, I have never seen a 5.3 volt USB charger, but the OEM charger
seems to be 5.3VDC and 2.0 Amps.

Must I get a car charger that is 5.3 volts?
(That's going to be hard to find.)

the class is the speed. don't worry about the type.

usb must be 5v +- 0.25v, or 4.75-5.25v, which means the oem charger is
not usb compliant.

they probably did that to reduce charge time but that's a really *bad*
way to do it.

what really matters is the amperage, and that's 2a. there are many 2a
chargers.

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.

I think the class is speed: for general storage purposes it doesn't
matter, but for e. g. storing (or rather, recording and playing back -
storing alone is OK of course) video, you need above a certain class.

The _type_ I _think_ may refer to an older format change that is also
sometimes referred to as HD - high density - in the case of SD cards:
some older equipment can't use cards that are HD. Non-HD cards go are
mostly up to 2G in size, though a few 4G are available; I don't think
you can find HD ones below 4G. But I could be wrong in thinking types I
and II are the same as non-HD and HD.

Also, I have never seen a 5.3 volt USB charger, but the OEM charger

I doubt it. Does your 'phone show "charging" when connected to a
friend's charger that doesn't say 5.3? Does it charge when connected to
a PC? You could always try anyway - they're cheap enough, if you can't
borrow one.

Looks like there's a *mistake* in the wirelessground.com web page, it

I can read it as 5.3 volts printed right on my charger!

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....

As others have said, it's not compliant with the USB charging spec, but
it's also only higher by a very slight amount, which should not matter.
The USB spec is for 4.75 to 5.25. Samsung is at 5.3. That could just
be someone writing the spec, rounding up and maybe the device itself is
compliant if you measured it.

In any case, any USB 2.0 charger will work.

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 USB data sockets on computers and USB Hubs often can't provide more
than 500 mA (0.5 A). That's why some gadgets, eg USB disc drives,
sometimes have a cable with two USB plugs - to get twice the power.

The 'next' USB standard, USB 3, will allow for more power to be
delivered. Meanwhile, smartphones and tablets are usually provided with
mains power adaptors which can provide more than 2 Amps, but with USB 2
style sockets so that the same USB cable can be used for charging (from
a mains power adaptor or car adaptor) and for data connections with
computers (which are very unlikely to have USB 3 sockets yet, as the
basic specification has only just been fixed). It's possible that some
computers or USB hubs may be able to provide 1 Amp or more from their
USB 2 sockets, if a device is plugged in that can use it.

The difference between "5.3 volts" and "5 volts" in the markings and
description of the mains chargers being argued about here, is probably
down to differing national regulations rather than to any actual
difference in the chargers themselves. USB chargers, and the power wire
in a computer's USB socket, is required to have its output "between 4.75
volts and 5.25 volts" according to the international standard; the
nominal voltage is 5. But I can imagine that some countries might
require that the device be marked with the maximum voltage it can
produce - and if the same country's laws round all voltage limits to one
decimal place, you end up with a marking of "5.3 volts" for a device
that does in fact produce no more than 5.25 volts (if you can find a
volt meter accurate enough to tell the difference).

If you want to have a smartphone in the car being charged up even while
it's in use (for navigation or music or whatever) then make sure the car
USB charge adaptor can manage 2 Amps (some can't).

If you get a branded item from the same shop as you got the handset
from, or a reputable dealer of that brand, there shouldn't be any
problems. Going for a cheap alternative, especially a 'fake', may well
end in tears.

Only disagree with the last part. I've bought a few chargers off of Ebay,
for $5 and have had no problems. If you buy it from the "dealer", eg
at the phone carrier store, it's typically $25+, which seems a bit steep
for a 5v charger.
