what kind of charger options I need for Samsung galaxy gt-i9000 ? Now I have copy of real Samsung charger called 'home charger' and options is TYPE:kj-tc14a input: 100-240V - 50/60Hz Max 0.1A OUTPUT: DC 5.2 - 450mA and I have original battery Samsung 3.7 V Li-ion battery 1500 mAh it is fine? Or I need different? I am worried about battery life and mobile if it is not exactly which is necessary. Maybe somebody can learn me things about charger things, thank you.
