Olympus Connector and Charger

[ElCucoArg]

Hi,

I'm from Argentina and bought an Olympus XZ-1 on ebay refurbished.
The camera is going to reach someone in the USA. That person is going to bring it to me here in Argentina.
This was no more than the camera and battery, no cables and manuals.

I bought the cap for the lens and a case that came out a few bucks more.

What I care about now is the charger and the USB cable.

As I see in Official Olympus XZ-1 page, This are the accesories:

USB Cable: CB-USB-6
Charger: AC F-2AC

I have two questions that I can not understand,

1. The CB-USB-6 is a cable that has USB on one side and across a mini USB or micro USB or any generic or is an owner of Olympus?

2. F-2AC charger as I understand it is connected to the camera and plug. What I wanted to know is if I can charge directly with the CB-USB-6 connected to the pc or I have to charge connected to the wall?

Regards, Martin.
