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.)
