Satio charging help please :(

[xman500]

Actually am confused what kind of charger should I buy for my Sony Ericsson satio... i saw it can be charged via w800i charger which is lying with me.. whats the role of the pins in the charger.. should i carry on charging with it or should I buy a new one? thanks in advance
